Improved use of resources is of enormously high relevance and crucial for achieving as well as maintaining a sustainable condition. Especially industrial production has a superior responsibility in creating a long-term viable way of living. However, there is a lack of systematic evaluation procedures for operational resources in production systems, meaning product material, energy, equipment and humans. Especially small and medium-sized enterprises, representing the largest number of all companies in Europe, are mostly not able to deal with these kinds of issues in addition to their daily business. The purpose of this licentiate thesis is the investigation for and development of an evaluation approach for resource efficiency and effectiveness in small and medium-sized enterprises. Two literature reviews and one industrial case study have been carried out. To start with, the first literature review founds a theoretical basis for the meaning of resource efficiency and effectiveness. The second literature review investigates latest measures and approaches for production system evaluation. In the next step an evaluation approach for resource efficiency and effectiveness evaluation in small and medium-sized enterprises is developed and tested within a single case study. The result consists of a comprehensive approach for small and medium-sized enterprises with focus on economic short-term and long-term improvements.

Background: High quality evidence on the cost-effectiveness of planned birth in alternative settings (at home, in a midwifery unit or an obstetric unit) has been lacking, and is a priority area for maternity policy. Aim: To provide evidence about the efficiency of the configuration of maternity care in England and to estimate the cost-effectiveness of alternative settings for intrapartum care for ‘low risk’ women, thereby providing guidance for commissioners, clinicians and for pregnant women and their families. Methods: A literature review of existing evidence was followed by four stand-alone empirical studies using different methods to determine the efficiency and cost-effectiveness of alternative settings for intrapartum care. Data from the Birthplace in England Programme of Research were analysed to explore whether there are differences in the efficiency of maternity units when they are stratified according to the type and scale of unit. Incremental cost-effectiveness ratios were used to estimate the short-term cost-effectiveness of different planned settings for birth for ‘low risk’ women and to develop a template for the design of decision-analytic models to estimate life-long cost-effectiveness for the mother and baby dyad. Findings: The larger obstetric units (OUs) tended to be more efficient than the smaller OUs. Less than half of free-standing midwifery units (FMUs) were operating at full efficiency. The cost of intrapartum and after birth care, and associated related complications, was less for births planned at home, in a free standing midwifery unit (FMU), or in an alongside midwifery unit (AMU) compared with planned births in an obstetric unit (OU). Planned birth in a FMU or in an AMU compared with an OU will generate incremental cost savings but with uncertainty surrounding the outcomes for the baby. Planned birth in all non-OU settings generated incremental cost savings and improved outcomes for mothers. For ‘low risk’ women having a second or subsequent birth, planned birth at home was found to be the most cost-effective option.

Annotation:

This thesis is an investigation of whether an energy efficiency obligation scheme would be cost-effective for the Swedish industrial sector. The basic guidelines of the scheme were constructed based on the characteristics proposed in the Energy Efficiency Directive and the previously implemented schemes in other EU Member States. In order to measure the cost effectiveness of the scheme for the industries, a Cost Benefit Analysis was performed. The results of the study show that the participation of the industries in an energy efficiency obligation scheme seems to be cost effective, and the Benefit to Cost Ratios of the analysis where ranging in numbers higher than one, showing that the benefits outweigh the costs. The scheme is in general more cost effective when scenarios assuming high policy intensity for the whole economy of the country are used as input for the calculation of the BCRs, which are also affected positively when higher fuel prices scenarios are adopted. The obligation should be placed upon the distributors, since the prices of energy distribution are administratively regulated. There is opportunity of financial benefits for the Swedish industries from agreements of energy savings delivery to the distributors in order for them to fulfill their obligation. These benefits will support the cost recovery of the investments for the energy savings measures. The possibility of certificate trading in the context of the scheme is another option that can create opportunities for financial gains and stimulate further the energy market. Basing the costs inputs from other EU Member States offers an insight on how these costs could be formed in the case of Sweden, but they cannot be taken as a complete calculation of the scheme’s financial effects. As a result, this study does not offer a final conclusion on the cost-effectiveness of the scheme; it rather serves as a means of support of the final conclusion regarding the cost-effectiveness of energy efficiency obligation schemes for the Swedish industries.

Annotation:

Livestock guarding dogs (LSGDs) have been used for centuries to reduce depredation on livestock and more recently, to facilitate the conservation of threatened predator species. Conservation NGOs (non-government organisations) in southern Africa promote the use of Anatolian Shepherds as LSGDs. However, livestock farmers in Botswana have been using a variety of different breeds for this purpose, including the local mixed-breed “Tswana” dogs. Postal, telephonic and face-to-face interview questionnaires were administered to 108 livestock farmers in Botswana to gauge how their LSGDs were being used, in order to determine what factors contributed to the success and affordability of these dogs. Eighty-three percent of farmers had LSGDs which equaled or decreased livestock depredations on their farms, with an average reduction in livestock depredation of 75% per year. This equated to an average saving of US$2,017 annually per farm. The costs of purchasing (average US$27) and maintaining the 198 LSGDs in my study (average US$169/LSGD/year) were very low compared to other countries and helped contribute to the high profits obtained by farmers (average US$1,497/farm or US$789/LSGD). A unique investigation of different breeds was possible due to the diverse array of breeds in the sample (Anatolian Shepherds, Cross Breeds, Tswana dogs, Greyhounds and Pitbulls), with the crossbreed dogs (Crosses and Tswana LSGDs) performing the best. LSGDs that reduced depredation and had minimal behavioural problems were the most likely to incite positive changes in their owners in regards to attitudes towards predators. Sixtysix percent of farmers stated that they were more tolerant of predators since obtaining a LSGD, and 51% reported that they were less likely to kill predators since obtaining a LSGD. My results indicate that successful, well-behaved LSGDs are a cost-effective tool that has the ability to increase farm productivity and improve predator-farmer conflicts in Botswana. The methods recommended in my thesis, in particular the benefits of using local breeds of dog as LSGDs, can be implemented on farming practices the world over to assist farming productivity and to promote conservation efforts.

This study compared the effectiveness, cost and efficiency of four formative evaluation conditions: (a) revision based on learner data (RLD), (b) revision based on expert data (RED), (c) revision based on both learner and expert data (RBD), and (d) revision without data (RND). Two more conditions were present in the study: materials in draft (MID) and no treatment (NT). The NT condition consisted of students who were tested without exposure to the instructional materials. The instruction that was formatively evaluated was a six-page article describing the relationship between diet and cancer. The article was written by chemistry professors for an "undergraduate chemistry course for non-science students". Undergraduates (n = 187) provided the effectiveness data. They randomly received one of the four formatively evaluated versions of the article, read the article, answered questions on an objective test, and indicated their confidence with respect to their responses. Professional revisors (n = 8) provided cost data. Each revisor provided cost estimates for all formative evaluation conditions. Efficiency was provided by combining effectiveness with cost data. Effectiveness differences were found between the MID and RLD, and the MID and RBD. The mean test scores, as well as the mean confidence-weighed test scores, of both RLD and RBD were significantly higher than those of the MID. Cost differences indicated three levels of cost. RND was the least costly formative evaluation condition. RLD and RED were equivalent in cost and more costly than RND. RBD was the most costly formative evaluation condition. With respect to efficiency, RLD was recommended. RLD was the least costly condition that was significantly more effective than MID. (Abstract shortened by UMI.)

Annotation:

Growing energy demand, depleting fossil fuels, and increasing environmental concerns lead to adaptation to clean and sustainable energy sources. Renewable energy sources are now believed to play a critical role in diminishing the deteriorating environment, supplying power to remote areas with no access to the grid, and overcoming the energy crisis by reducing the stress on existing power networks. Therefore, an upsurge in renewablesbased energy systems development has been observed during the previous few decades. In particular, solar PV technology has demonstrated extraordinary growth due to readily available solar energy, technological advancement, and a decline in costs. However, its low power conversion efficiency, intermittency, high capital cost, and low power quality are the major challenges in further uptake. This research intends to enhance the overall performance of PV systems by providing novel solutions at all levels of a PV system hierarchy. The first level investigated is the solar energy to PV power conversion, where an efficient maximum power point tracking (MPPT) method is developed. Secondly, the dc to ac power conversion is explored, and an optimal PV system sizing approach with abidance to power quality constraints is developed. Finally, smart power management strategies are investigated to utilise the energy produced by solar PV efficiently, such that the minimum cost of energy can be achieved while considering various technical constraints. The methods involve Genetic Algorithm (GA) for finding the optimal parameters, mathematical models, MATLAB/Simulink simulations of solar PV system (including PV arrays, dc/dc converter with MPPT, batteries, dc/ac inverter, and electric load), and experimental testing of the developed MPPT method and power management strategies at the smart energy lab, Edith Cowan University. Highly dynamic weather and electricity consumption data encompassing multiple seasons are used to test the viability of the developed methods. The results exhibit that the developed hybrid MPPT technique outperforms the conventional techniques by offering a tracking efficiency of above 99%, a tracking speed of less than 1s and almost zero steady-state oscillations under rapidly varying environmental conditions. Additionally, the developed MPPT technique can also track the global maximum power point during partial shading conditions. The analyses of power quality at the inverter’s terminal voltage and current waveforms revealed that solar PV capacity, battery size, and LC filter parameters are critical for the reliable operation of a solar PV system and may result in poor power quality leading to system failure if not selected properly. On the other hand, the optimal system parameters found through the developed methodology can design a solar PV system with minimum cost and conformance to international power quality standards. The comparison between the grid-connected and stand-alone solar PV system reveals that for the studied case, the grid-connected system is more economical than the stand-alone system but outputs higher life cycle emissions. It was also found that for grid tied PV systems, minimum cost of energy can be achieved at an optimal renewable to grid ratio. Additionally, applying a time varying tariff yields a slightly lower energy cost than the anytime flat tariff. A sensitivity analysis of the reliability index, i.e., loss of power supply probability (LPSP), demonstrates that for the stand-alone PV systems, there is an inverse relationship between LPSP and cost of energy. Contrarily, for grid-connected systems, the cost of energy does not vary significantly with the change in LPSP.

The thesis project explores the use of an optimization methodology for selecting the lowest monetary cost combinations of technologies to meet a set operational energy efficiency targets for buildings. The optimization approach, which is operated on a normative energy model, is compared with existing prescriptive methodologies for selecting technology combinations and a metric is developed for ranking their effectiveness; the E/C Ratio. The energy savings/ cost ratio is also the objective function that the optimization algorithm is set to maximize. The optimization routine is coded in to a custom MATLAB script and is used in two case studies to optimize a proto-typical Korean apartment and office building. The optimization methodology finds technology combinations that are much more cost effective than the prescriptive methodology at meeting an energy savings target and can generically be applied to other buildings given a palette of technology alternatives and the corresponding cost data.

The objective of this work is the evaluation of the impact of new direct acting antivirals for Hepatitis C as a case of disruptive healthcare innovation that challenged healthcare systems. Two systematic reviews address cost-utility analyses of new therapies and productivity costs of Hepatitis C. Then we present an assessment of clinical guidelines update at a European level from 2016 to 2018 and the method addresses methodological issues identified as lacking in previous works. Specifically, the Markov model included productivity cost measurement and real drug acquisition costs. The results confirm that European update on Hepatitis C treatment recommendations was efficient as it yielded health gains and savings on the cost side. Economic evaluation can be useful not only to assess healthcare innovations, but also as an efficiency test of clinical decisions.
L’objectiu d’aquest treball és l’avaluació de l’impacte de nous antivirals d’acció directa per a l’hepatitis C com a innovació sanitària disruptiva que va desafiar els sistemes sanitaris. Dues revisions sistemàtiques analitzen els estudis de cost-utilitat de les noves teràpies i els costos de productivitat de l’hepatitis C. A continuació s’avalua l’actualització de les recomanacions clíniques a nivell europeu entre el 2016 i el 2018 i el mètode inclou qüestions metodològiques que s’han identificat com a mancances en treballs anteriors. En concret, el model Markov incorpora els costos de productivitat i els costos reals d’adquisició dels medicaments. Els resultats confirmen que l’actualització europea sobre les recomanacions de tractament contra l’hepatitis C va ser eficaç, ja que va generar guanys en salut i estalvis en costos. L’avaluació econòmica pot ser útil no només per avaluar les innovacions sanitàries, sinó també com a test d’eficiència de les decisions clíniques.

Providing an economic case for establishing new protected areas and demonstrating how conservation enhances human well-being is becoming necessary to reinforce moral arguments for biodiversity protection. Accordingly; this study aimed to assess whether the spatial distribution of priority areas changes in accordance with gains in economic-efficiency when ecosystem service benefits are explicitly considered. Using the site-selection software Marxan, priority areas for South Africa were identified under four scenarios, two of which incorporated a spatial cost benefit analysis of the opportunity costs and ecosystem service benefits associated with conservation. Additional scenarios assessed how reserve design and costs changed when communal-land agriculture and resource use were weighted to account for the social costs of conservation. Opportunity costs were spatially variable and greatest in regions where mixed commercial farming was practiced. Economic benefits exceeded costs in the western interior, northern regions and along the eastern coastline. These areas contracted when ecosystem service benefits were more conservatively estimated by applying the principle of additionality. There was minimal to moderate spatial agreement between the scenarios (0.12 < κ < 0.55).When economic benefits were considered, areas that made more economic sense from a conservation management perspective were prioritized. These changes in spatial distribution were associated with gains in economic efficiency. The cost: benefit ratio was ca. 10 times greater than when no economic variables were considered (scenario 1 = 10.44 vs. scenario 4 = 1.15). When heavy weightings (> 100) were applied, the reserve systems became dispersed (R = 0.91 (for weighting factor of 10), R = 0.52 (for weighting factor of 1000)) in the former homelands and more costly overall (difference of R2.95B between the extremes). Considering the economic benefits of conservation changes the spatial distribution of priority areas and improves their economic efficiency. Disregarding economic benefits may compromise the implementation potential of priority areas, particularly when the economic benefits of competing land-uses are brought to the table. Furthermore, it is important to explicitly consider the social costs of conservation and consider resettlement or compensation costs among the trade-offs.

There is a growing recognition that we cannot afford the provision of all new health care technologies, even those that are proven to be beneficial. This is increasingly true in the US, where health care spending is on an unsustainable upward trajectory. US health care spending is greatly in excess of that of other countries; however, with respect to key health metrics, the US health care system performs relatively poorly. Despite this, unlike many other developed countries economic evaluation, and more specifically cost effectiveness evidence, is used sparingly in the US health care system. Notably, the Centers for Medicare and Medicaid Services (CMS), administrators of the Medicare programme, state that cost-effectiveness evidence is not relevant to coverage decisions for medical technology and interventions evaluated as part of National Coverage Determinations (NCDs). The empirical aspect of this thesis evaluates the current use and potential value of using cost-effectiveness evidence in CMS NCDs. A database was built using data obtained from NCD decision memoranda, the medical literature, a Medicare claims database, and Medicare reimbursement information. The findings of the empirical work show that, CMS’s stated position notwithstanding, cost-effectiveness evidence has been cited or discussed in a number of coverage decisions, and there is a statistically significant difference between positive and non-coverage decisions with respect to cost effectiveness. When controlling for factors likely to have an effect on coverage decisions, the availability of cost-effectiveness evidence is a statistically significant predictor of coverage. In addition, the quality of the supporting clinical evidence, the availability of alternative interventions, and the recency of the decision are statistically significant variables. Further, when hypothetically reallocating resources in accordance with cost-effectiveness substantial gains in aggregate health are estimated. It is shown that using cost-effectiveness to guide resource allocation has an effect on resource allocation across patient populations and types of technology.

ENGLISH ABSTRACT: Wine cellars are diverse in terms of equipment types and process configurations. Whilst other food production processes have, in many cases, been properly analysed and modelled, this process diversity has resulted in an absence of process analyses in the wine industry. Each wine cellar is unique and represents a fully integrated agro-business, starting with a raw material (grapes) and extending to marketing and selling of the final product (wine). This makes the wine industry unique in this context. This study is the first attempt to analyse winemaking procedures in the form of a process audit. The study was approached in the following manner: • A questionnaire was developed to assess cellar configurations and conditions. This questionnaire was submitted to a statistically significant number of cellars, and a statistically significant number of questionnaires were returned. • The data collected from the questionnaire were statistically analysed and associations between equipment or procedures and wine faults were identified. • Three cellars were studied in depth. These three cellars had their processes audited and their effluent characterised. Additional data were obtained from current sampling projects and these data were analysed to complement the data obtained from the questionnaire • A preliminary input/output model was developed. The major results of this study are: • It was found that certain faults that appear in wine might be associated with equipment and/or process faults. These associations are statistically significant and they show that cellar hygiene is of critical importance when assessing these wine faults. The most important of these faults are VA, microbial contamination of the wine, sluggish and stuck fermentations. A risk hierarchy was derived to indicate which events are associated with others most strongly. • It was found that few wineries measure water consumption and even fewer wineries measure the quantity of effluent produced. • Correlations have been developed to predict winery parameters in terms of tons of grapes pressed per annum. These parameters include water and electricity consumed, wine produced and the quantity of effluent produced. Effluent characteristics have also been correlated to the tons of grapes pressed per annum. These characteristics include chemical oxygen demand, sodium absorption ratio and total dissolved solids in solution. Chemical oxygen demand was identified as the most important contributing factor in winery effluent. It was shown that all variables rise with an increase in cellar size, but the rise is not linear. This implies that large cellars have greater quantities of effluent of lower quality than small cellars. Most cellars have effluent concentrations that require some form of effluent treatment. The characterisation of effluent shows that the most widely used disposal practice is irrigation, and that the effluent disposed in this manner does not meet legislative requirements. • A preliminary input/output model was developed in order to enable wineries that have not measured the relevant parameters to predict the abovementioned variations. The resolution of these predictions is low but the model serves to provide an initial estimate if there are no data available. The model will give industrial averages for any given cellar size. • An economic balance was performed using this preliminary model. It was shown that if cellars were to lower the consumption of utilities and to reduce the strength of their effluent (using cleaner practices and not dilution) the reduction of operating costs could be reduced by 14% for smaller cellars to 17% for larger cellars. This study has shown that it is possible to make wine in a more environmentally friendly manner, producing better quality wines, without incurring extra costs.
AFRIKAANSE OPSOMMING: Wynkelders is diverse eenhede ten opsigte van die tipe toerusting en prosesse wat gebruik word. Terwyl ander prosesse rondom voedselproduksie in baie gevalle reeds geanaliseer en gemodelleer is, het die diversiteit in die wynindustrie gelei tot 'n afwesigheid van prosesanalises. Elke wynkelder is uniek en verteenwoordig 'n ten voile geintegreerde agro-besigheid wat begin met die rou materiaal (druiwe) en lei tot die bemarking en verkope van die finale produk (wyn), 'n eienskap wat die wynindustrie uniek maak in hierdie verband. Hierdie studie is die eerste poging om die wynmaakproses in die vorm van ‘n proses-oudit te analiseer. Die studie is soos volg aangepak: • ‘n Vraelys is ontwikkel om kelderkonfigurasies en -toestande te ondersoek. Die vraelys is aan ‘n statisties betekenisvolle aantal kelders voorgele, en ‘n statisties betekenisvolle aantal vraelyste is terugontvang. • Die data wat uit die vraelyste ontvang is, is statisties ontleed en verwantskappe tussen toerusting of prosesse en wyngebreke is geidentifiseer. • Drie kelders is in diepte bestudeer. Hierdie drie kelders se prosesse is geoudit en die afvloeiwater is gekarakteriseer. Addisionele data is verkry van huidige projekte en hierdie data is ge-analiseer om die data van die vraelys aan te vul. • ‘n Voorlopige inset / uitset model is ontwikkel. Die belangrikste resultate van hierdie studie is: • Dit is bevind dat sekere gebreke wat in wyn voorkom geassosieer kan word met tekortkominge in toerusting en/of prosesse in die kelder. Hierdie assosiasies is statisties betekenisvol en toon dat kelderhigtene van kritiese belang is wanneer gebreke in wyn ondersoek word. Die mees belangrike gebreke wat voorkom is vlugtige suur, mikrobiese kontaminasie van wyn, slepende en gestaakte fermentasie. ‘n Risikohierargie is afgelei om die gebeure te toon wat die sterktste met mekaar geassosieer word. • Dit is gevind dat min wynkelders waterverbruik meet. Selfs minder kelders meet die hoeveelheid afvloeiwater wat geproduseer word. • Korrelasies is ontwikkel om kelderparameters te voorspel in terme van ton druiwe gepars per jaar. Hierdie parameters sluit in water- en elektrisiteitsverbruik, wyn geprosuseer en hoeveelheid afvloeiwater geproduseer. Eienskappe van afvloeiwater is ook gekorreleer met die ton druiwe wat per jaar gepars word. Hierdie eienskappe sluit in chemiese suurstofbehoeftes, natrium absorpsieverhoudings en totale opgeloste soliede materiaal in oplossing. Chemiese suurstofbehoeftes is geidentifiseer as die mees belangrike bydraende faktor tot afvloeiwater in kelders. Dit is getoon dat alle veranderlikes verhoog hoe groter die kelder, maar hierdie verhoging is nie lineer nie. Dit impliseer dat groter kelder meer afvloeiwater van ‘n laer kwaliteit produseer. Die meeste kelders produseer afvloeiwater van sodanige konsentrasies dat behandeling daarvan nodig is. Die ondersoek van hierdie afvloeiwater toon dat die mees algemene wyse van wegdoening van afvloeiwater besproeiing is, en dat afvloeiwater wat op hierdie manier weggedoen word, nie voldoen aan die wetgewing se vereistes nie. • 'n Voorlopige inset/uitset model is ontwikkel om kelders wat nie die toepaslike parameters gemeet het nie in staat te stel om hierdie parameters te voorspel. Die akuraatheid van hierdie voorspellings is nie hoog nie, maar die model verskaf ‘n aanvanklike skatting waar daar geen data beskikbaar is nie. Die model verskaf industriele gemiddeldes aan kelders van enige grootte. • ‘n Ekonomiese balans is uitgevoer deur van hierdie model gebruik te maak. Dit is getoon dat indien kelders die gebruik van water en elektrisiteit verminder en die konsentrasie van afvloeiwater verlaag (deur van skoner paktyke gebruik te maak, en nie verdunning nie) die bestuurskoste met 14% vir kleiner kelders tot 17% vir groter kelders verlaag kan word. Die studie het getoon dat dit moontlik is om wyn te maak op ‘n meer omgewingsvriendelike wyse, en sodoende beter kwaliteit wyn te produseer sonder addisionele kostes.

ENGLISH ABSTRACT: Since 1988 it became practice for welfare organisations to submit an evaluation of their welfare programme as part of their application for state funding for the next year. Included in this evaluation is a section on the cost efficiency of the programme. After the first democratic election in 1994 a number of processes were started to develop new welfare policies for the country. In all of these processes cost efficiency is seen as a principle, but in spite of this, so it seems from the documents, is the evaluation of cost efficiency still a problem. The question therefore arises: What is the present status of the evaluation of the cost efficiency of social services after twelve years of program evaluation? Only a few studies on the methodology of the evaluation of cost efficiency within the South African context were found through the literature study. An exploratory study was therefore undertaken to determine what the reasons could be why so little progress was made with cost effiency evaluation. The empirical study focussed on residential facilities for older persons and was done within one welfare organisation in the Western- and Southern Cape. A sample of twenty managers was randomly selected and fifteen respondents returned the questionaire. It is a potential danger that managers of residential facilities for older persons could see the evaluation of the services rendered as just another administrative task, because of the very strong link between evaluation and the application for state funding. The researcher therefore wanted to ascertain what the attitude of the managers is towards the evaluation of their services, and especially the evaluation of the cost-efficiency thereof. It was found that the managers are positive towards program evaluation and the evaluation of cost efficiency, but the majority of them responded that the lack of guidelines and manuals is a deficiency. The lack of proper measuring instruments was also stressed. The research also shown that the managers conceptualize cost efficiency mainly in terms of costs and not as a relation between the outcomes of the programme and the costs thereof. The managers of residential facilities uses the evaluation document that was send out by the department, because it forms part of the application for state funding. This means that the level of program evaluation is actually determined by the department. It was found that this document focused mainly on the measuring of inputs and outputs and not so much of the evaluation of the outcomes of the programme. Based on the results of the study the researcher proposed guidelines to promote the evaluation of the cost efficiency of social services.
AFRIKAANSE OPSOMMING: Dit is sedert 1988 praktyk dat vrywillige welsynsorganisasies jaarliks 'n evaluering van hulle maatskaplikewelsynsprogram moet indien as deel van die aansoek om staatsubsidie vir die volgende jaar. By hierdie evaluering van die maatskaplikewelsynsprogramme is die evaluering van die kostedoeltreffendheid van die program ingesluit. Na die eerste demokratiese verkiesing in 1994 het verskeie prosesse aan die gang gekom om nuwe maatskaplikewelsynsbeleid vir Suid-Afrika te ontwikkel. In al die dokumente wat deur die prosesse ontwikkel is, word die kostedoeltreffendheid van maatskaplikewelsynsdienste as 'n belangrike beginsel gestel. Tog blyk dit, uit die verslae van sommige van die prosesse, dat die evaluering van kostedoeltreffendheid 'n probleem blyk te wees. Die vraag ontstaan dan tereg: Wat is die huidige stand van die evaluering van die kostedoeltreffendheid van maatskaplikewelsynsprogramme twaalf jaar sedert die implementering van programevaluering? Uit die literatuurstudie het dit geblyk dat daar min studies in Suid-Afrika bestaan wat handel oor die metodiek van kostedoeltreffendheidsevaluering van maatskaplikewelsynsprogramme. Verkennende navorsing is onderneem om vas te stel waarom daar oënskynlik min vordering gemaak is met die evaluering van kostedoeltreffendheid van maatskaplikewelsynsprogramme. Die empiriese studie het gefokus op residensiële fasiliteite vir ouer persone en die navorsing is uitgevoer by een welsynsorganisasie in die Wes- en Suid-Kaap. 'n Steekproef van twintig bestuurders is op ewekansige wyse geselekteer en vyftien respondente het die vraelys teruggestuur. Die gevaar bestaan dat, vanweë die sterk verband tussen die evaluering van die program en die aansoek vir subsidie, die evaluering van die maatskaplikewelsynsprogram bloot net as nog 'n administratiewe taak gesien kan word. Daarom wou die navorser vasstel wat die bestuurders van residensiële versorgingsprogramme vir ouer persone se houding jeens programevaluering en die evaluering van die kostedoeltreffendheid van die program is. In die studie is bevind dat die bestuurders positief jeens programevaluering en die evaluering van die kostedoeltreffendheid van die programme is, maar die oorgrote meerderheid bestuurders het aangedui dat hulle dit as 'n leemte sien dat daar min riglyne of handleidings bestaan. Die gebrek aan meetinstrumente is ook beklemtoon. Uit die studie het dit verder geblyk dat die bestuurders die konsep kostedoeltreffendheid hoofsaaklik in terme van koste verstaan, en nie in terme van 'n verhouding van die uitkomste van die program tot die koste daarvan nie. Die bestuurders van residensiële fasiliteite voltooi jaarliks die evalueringsdokument van die betrokke staatsdepartement, omdat dit deel vorm van die aansoekprosedure vir staatsubsidie. Hierdie dokument bepaal derhalwe die vlak van programevaluering. Dit het uit die studie geblyk dat die dokument wat gebruik word grootliks fokus op die meting van insette en uitsette en nie soseer op die uitkomste van die welsynsprogramme nie. Gebaseer op die bevindinge van die navorsing is riglyne voorgestel wat sal meewerk om die evaluering van die kostedoeltreffendheid van maatskaplike dienste te bevorder.

ENGLISH ABSTRACT: Manufacturers can gain a competitive advantage through lower production cost, better quality, better efficiencies and being more flexible and dependable than its competitors. Lower production cost can be a result of first-time-right quality products and efficient production processes in terms of throughput. Low production cost is not a destination but a journey where the goalpost will always move as competitors will continuously come up with ideas to lower prices and margins have to be cut in order to stay competitive. This is where manufacturers must come up with initiatives to continuously drive its operational metrics to remain competitive. This research report will explain how Distell's biggest bottling plant, Green Park, successfully introduced Process Control to increase its quality operational metric and a Six Sigma project to reduce downtime to increase its efficiency operational metric to drive its operational costs down. Process Control was introduced as a TOM initiative with a subsequent reduction in rework due to poor quality (thousands) from R1 585 to R484. This contributed to 'first-time-right' production, better efficiencies and not tying up valuable production time with reworks. The Six Sigma principles were used on a production line to introduce initiatives to reduce changeovers and unplanned downtime to improve its GEE. This initiative has a projected benefit of R687 (thousands). The report also indicated that a 1% increase in Green Park's overall GEE will result in 1% saving of production hours resulting in a 1% saving of variable cost. This will result in an OEE of 63% that will save 226 hours and R410(thousands).
AFRIKAANSE OPSOMMING: Vervaardigers kan 'n kompeterende voorsprong verkry deur laer produksiekoste, beter gehalte en groter doeltreffendheid te bewerkstellig en deur meer buigbaar en betroubaar as hul teestanders te wees. Goeie gehalte produkte wat die eerste keer reg is en doeltreffende produksieprosesse vir verwerkingskapasiteit kan laer produksiekoste tot gevolg het. Lae produksiekoste is nie 'n bestemming nie, maar 'n reis waartydens die doelpale sal skuif met teestanders wat deurgaans met idees om pryse te verjaag, vorendag sal kom. Winsgrense sal moet verklein word om kompeterend te bly. Hier moet vervaardigers inisiatief aan die dag lê om hul operasionele meetbares te dryf om kompeterend te bly. Hierdie navorsingsverslag sal verduidelik hoe Distell se grootste botterings aanleg, Green Park, prosesbeheer (Process Control) suksesvol in werking gestel het om sy meetbares wat operasionele gehalte betref, te verhoog, en 'n Six Sigma-projek ingestel het om staantyd te verminder sodat sy meetbares wat operasionele doeltreffendheid betref, kan verhoog en sy operasionele koste sodoende besnoei word. Prosesbeheer is as algehele gehaltebestuursinisiatief ingestel met 'n gevolglike vermindering van herverwerking weens swak gehalte (duisende) van R1 585 na R484. Dit het bygedra tot groter doeltreffendheid met produksie wat uit die staanspoor reg is, en verhoed dat kosbare produksietyd op herverwerking gespandeer word. Die Six Sigma-beginsels is in 'n produksielyn gebruik om inisiatiewe in werking te stel om oorskakelings en onbeplande staantyd ter verbetering van die algehele toerustingsdoeltreffendheid (OEE), te verminder. Hierdie inisiatief hou 'n geprojekteerde voordeel van R687 (duisende) in. Die verslag dui verder aan dat 'n 1%-verhoging in Green Park se algehele OEE sal lei tot 'n 1% besparing in produksie-ure, wat 'n 1% besparing op veranderlike koste tot gevolg het. Dit sal tot 'n OEE van 63% lei, wat 226 uur en R410 (duisende) sal spaar.

Cost-effectiveness models for health care interventions generally make the assumption that all resources are available, as required, without capacity constraints. This assumption may be a reasonable approximation of the truth for a range of questions faced by decision makers in health care. However, in some health care settings, capacity constraints predominate leading to queue development. In these situations the use of a modelling technique that can accommodate these constraints would appear advisable to allow the efficiency of competing healthcare interventions to be determined. Nevertheless, there have been no empirical comparisons of economic modelling techniques that capture capacity constraints and those that do not. Further, there are only a few cost-effectiveness analyses (CEA) of health care that capture the effect of capacity constraints at all. This research seeks to explore these gaps in the literature in an applied manner.

Introduction: Ensuring universal access to primary health care (PHC) is a key component of the Ethiopian nationalhealth policy. The policy also emphasises promoting and enhancing national self-reliance in health development bymobilizing and efficiently utilizing resources including community participation. To this end, the government introducedthe accelerated expansion of the PHC strategy through a comprehensive health extension programme (HEP). HEP is afamily and community-based health care delivery system institutionalised at health post level which combines carefullyselected high impact promotive, preventive and basic curative interventions. All HEP interventions are promotive and preventive except the malaria intervention which, in addition, incorporates a curative service. In the country, malaria is a leading disease. Unlike most Sub-Saharan African countries where P. falciparum accounts for almost all malaria infections, in Ethiopia both P. falciparum and P. vivax are co-dominant. Considering this peculiar epidemiological nature, the national guideline recommends alternative diagnosis and treatment strategies. Rationale: The lack of adequate resources and the efficiency with which available resources are being utilised are the main challenges in any health care setting. Therefore, if the HEP which consumes consideral amount of resource desires to reach its intended goal, monitoring and improving its efficiency is of great public heath importance. HEP has been successful in improving access to PHC including the malaria diagnosis and treatment service. Though this is a crucial measure, its quality ought to be considered. For the malaria curative service, studying the cost-effectiveness of the available strategy and patients’ adherence to the treatment regimen can be considered as proxy measures of quality for which local evidence is lacking. However, none of the existing studies in this field of research has addressed the Ethiopian malaria epidemiological context and its diagnosis and treatment guideline. In Tigray, for more than two decades, access to malaria early diagnosis and prompt treatment was facilitated by volunteer community healthworkers (CHWs). However, with the introduction of artemether-lumefantrine (AL) the service was compromised mainly for reasons of cost, safety and logistic. Therefore, it was important to explore the feasibility and the impact of community deployment of AL with rapid diagnostic tests (RDTs). The aim: to explore the overall performance of HEP and particularly the access to and quality of malaria early diagnosis and prompt treatment in the Tigray region of Ethiopia. Methods: Different study designs and populations were used for each of the four specific objectives. Data envelop analysis (DEA) was applied to assess the HEP efficiency. For this, register data for the output variables and primary data for the input and the environmental factors were collected. A health provider perspective cost-effectiveness analysis was used to determine which among the currently available diagnostic and treatment strategies is best for the country. Effectiveness data were generated from a stratified cross-sectional survey and secondary data were used to calculate the cost. For measuring adherence to the six-dose AL regimen, an assessment questionnaire and pill count was employed at patients´ home. To determine whether deploying AL with RDT at community level was feasible and effective, a number of designs were used: longitudinal follow-up, cross-sectional surveys, cost analysis, verbal autopsyquestionnaires and focal group discussions. Main findings: More than three-quarters of the health posts were found to be technically inefficient with an average score of 42%, which implies potentially they could improve their efficiency by 58%. Scale of operation was not a cause of inefficiency. None of the considered environmental factors was associated with efficiency. The Parascreen-based strategy (multispecies RDT-BS) was found to be the most cost-effective strategy, which allowed treating correctly an additional 65% of patients with less cost than the paracheck-BS. Presumptive-BS was highly dominated. Among P.falciparum positive patients to whom AL was prescribed, more than a quarter did not finish their treatment. The main reasons for interrupting the dose were ‘too many tablets’ and ‘felt better before finishing the dose’. The ownership of aradio, the belief that malaria cannot be treated traditionally and a delay of more than one day in seeking treatment after the onset of fever were significantly associated with being adherent. Deploying AL with RDT at community level was demonstrated to be effective and feasible. In the intervention district, almost 60% of suspected cases were managed by CHWs. Malaria transmission was lower at least threefold and malaria mortality risk by around 40% compared to the control district. The use of RDTs reduced cost and possibly the risk of drug resistance development. Conclusion: Though improving access to health care is important, it should be considered a means, not an end. Themore accessible a system is the more people could utilise it to improve their health. Thus, ensuring the access obtainedthrough HEP is maintained, its quality is improved and efficiently utilised to its optimal productivity level is a necessarytask. The DEA study revealed a high level of inefficiency where majority of the health posts needed improvement.This thesis also found parascreen-BS to be the most cost-effective strategy and that there is no epidemiological andeconomical contextual justification to keep both, the presumptive-BS and the RDT-BS specific only to P.falciparum.The high poor adherence levels raises great concern as it leads to recurrent malaria attacks of the patient, speed upthe development and spread of drug resistance strains and reduces the effect of the drug on the transmission. Therefore,providing effective drug alone is not sufficient; assessing and monitoring adherence to the treatment is by faressential. Deployment of AL with RDT through a community-based service has shown an enormous impact in termsof cost, transmission, morbidity and mortality. However, it is worth noting that this results came from an area wherea community-based service has been involved in the PHC system for more than three decades.

The present paper describes an innovative electro-hydraulic system developed for automated side loaders. The system is based on Intelligent Flow Control (IFC), a concept where open circuit electric displacement controlled pumps are coupled with EH directional control valves. IFC was selected in order to achieve the level of performance required, in terms of efficiency and productivity (i.e. cycle times), and also to provide the best possible control of the side loader arm. The paper describes the system layout and the basics of the controls: from the alghorithms of the arm actuators to the vehicle on board telemetry and diagnostic. The paper reports the comparison between the IFC system (implemented on the vehicle) and a more traditional approach based on a Load Sense Flow Sharing concept. The benefits of the IFC solution are highlighted focusing on the energy efficiency (very important especially in the case of CNG engines, where the torque available at idle is significantly lower than diesel engines), but also in terms of controlability and response (due to the lack of load sensing signal lines).

Can smart metering program and time-of-use (TOU) prices help reduce energy consumption in New York City? Being able to track electricity consumption levels and to modify consumer usage patterns are important for policy makers to efficiently manage the energy markets. Unfortunately, no reliable and up-to-date data have been brought to bear on this question. I study the effects of time-of-use (TOU) prices and smart metering for the residents of Shanghai and I investigate further what can policy makers do in order to adapt and transfer this successful DSM experience from Shanghai to the residential sector in New York City. The primary objective of my study is to characterize the realistic short-term and long-term potential for the smart metering program in New York City given my empirical findings that the smart metering program has had brought great benefits to the residents of Shanghai. People respond to incentives; if electricity is charged at different prices throughout a day, consumers are likely to shift their usage to when it is cheaper. My findings suggest that policy makers should think harder about designing a pricing scheme that can optimize the social plus

This research evaluates the impact of automated and semi-automated devices on the process of loading, discharging, stacking and un-stacking of containers using Quayside Cranes (QSCs), Straddle Carriers (SCs), Rubber Tyred Gantry cranes (RTGs) and Rail Mounted Gantry cranes (RMGs) in container terminals. The emphasis of study is on the assessment of performance and cost effectiveness of the existing automated quayside and yard cranes. The study in this thesis examines the economic implications of reducing QSCs' cycle-times brought about by automatic features installed on the post-Panamax cranes. It demonstrates that a considerable increase in the productivity of QSCs is related directly or indirectly to an expected reduction of crane cycle-times. The concept offered by the proposed improvements distinguishes between the traditional system of loading and discharging of containers and the automated methods. It implies that automation devices installed on conventional QSCs significantly reduce the total turnaroundtime and hence the cost of containerships' waiting-times. It argues, however, that there should be a balance between the cost of containerships' waiting-times and the cost of automated berths' unproductive-times (idle-times). This study uses the elements of queuing theories and proposes a novel break-even method for calculating such a balance. The number of container Ground Slots (GSs) and the annual throughput of container terminals expressed in Twenty-foot Equivalent Units (TEUs) have been used as the efficiency and performance measure for many years. The study in this thesis introduces appropriate container yard design layouts and provides a generic model for calculating the annual throughput for container terminals using semiautomated SC and RTG and automated and semi-automated RMG operating systems. The throughput model proposed in this study incorporates the dynamic nature, size, type and capacity of the automated container yard operating systems and the average dwell-times, transhipment ratio, accessibility and stacking height of the containers as the salient factors in determining a container terminal throughput. Further, this thesis analyses the concept of cost functions for container yard operating systems proposed. It develops a generic cost-based model that provides the basis for a pair-wise comparison, analysis and evaluation of the economic efficiency and effectiveness of automated and semi-automated container yard stacking cranes and helps to make rational decisions. This study proposes a Multiple Attribute Decision-Making (MADM) method for evaluating and selecting the best container yard operating system amongst alternatives by examining the most important operating criteria involved. The MADM method proposed enables a decision-maker to study complex problems and allows consideration of qualitative and qualitative attributes that are heterogeneous in nature. An Analytical Hierarchy Process (AHP) technique has been employed as a weighting method to solve the MADM problem. The AHP allows for the decomposition of decision problem into a hierarchical order and enables a pair-wise comparison of the attributes and alternatives. The results of the AHP analysis provide the basis for a pair-wise comparison, judgement and selection of the best automated or semi-automated container yard operating system.

The aim of the thesis is to determine why there are set wrong conditions of public expenditure programs to improve energy efficiency in the Czech Republic. The thesis analyzes conditions of funding and planning of specific projects funded by the Operational Environment program. The main criterion for evaluating projects is the consideration of energy efficiency. Methodologically, the research is based on an analysis of secondary data and the concept of cost-effectiveness. Based on the analysis, recommendations are made for changes in processes and parameterization of public expenditure programs in order to take account of higher energy efficiency criteria in the design and selection of supported projects, and thus be the energy efficiency target for 2020 by 20% could be achieved.

Buildings have a significant impact on energy usage and the environment. Much of the research in architectural sustainability has centered on economically advanced countries because they consume the most energy and have the most resources. However, sustainable architecture is important in developing countries, where the energy consumption of the building sector is increasing significantly. Currently, developing countries struggle with vaccine storage because vaccines are typically warehoused in old buildings that are poorly designed and wasteful of energy. This thesis created and studied a decision support tool that can be used to aid in the design of economically feasible Net Zero Energy vaccine warehouses for the developing world. The decision support tool used a simulation-optimization approach to combine an optimization technique with two simulation softwares in order to determine the cost-optimal design solution. To test its effectiveness, a new national vaccine storage facility located in Tunis, Tunisia was used. Nine building parameters were investigated to see which have the most significant effect on the annual energy usage and initial construction cost of the building. First, tests were conducted for two construction techniques, five different climates in the developing world, and three photovoltaic system prices to gain insight on the design space of the optimal solution. The results showed the difference between an economically efficient and economically inefficient Net Zero Energy building and the results were used to provide generalized climatic recommendations for all the building parameters studied. The final test showed the benefits of combining two optimization techniques, a design of experiments and a genetic algorithm, to form a two-step process to aid in the building design in the early stages and final stages of the design process. The proposed decision support tool can efficiently and effectively aid in the design of an economically feasible Net Zero Energy vaccine warehouse for the developing world.

There is little understanding of the implementation efficiency and effectiveness of restoring plant invaded landscapes within operational contexts. South Africa's Working for Water (WfW) programme is arguably the most ambitious alien plant control programme in the world, yet little is known about its cost-effectiveness and the challenges it faces in linking poverty and environmental objectives. My first aim was to assess the cost-effectiveness of invasive plant removal, and the factors that underpin its effectiveness over large spatial and temporal scales. The second aim was to compare the accuracy of evidence-based findings with managers' experience-based beliefs, and to assess whether managers are willing to change their beliefs after being exposed to it. The third aim was to assess the costs and benefits of removal versus removal followed by active native re-vegetation. My final aim is to assess the challenges and lessons learnt by managers linking ecological restoration with poverty alleviation objectives, specifically within the public works model. My study area was focused primarily on two WfW river catchment projects in the western region of the Eastern Cape province. I adopted an interdisciplinary approach drawing from a range of methods such as observational studies, statistical modelling and interviews with managers. The key findings were that control efforts in the two catchment projects are largely inadequate owing to many sites being re-invaded and not enough resources being allocated to the catchments. It would take between 54 and 695 years to clear the respective catchments. In terms of cost-effectiveness, my results exceeded previous estimates by 1.5 to 8.6 times for each catchment project. After being exposed to the evidence-based findings, the managers did not change their beliefs when it came to forecasting the future effectiveness. I found that active native re-vegetation after removal of invasive plants is very costly and that priority should be given to understanding the effectiveness of the removal treatments on native species recovery. The managers cited significant challenges in effectively and efficiently meeting the programmes dual objectives. Based on a broader review of the public works literature I recommend WfW re-examine the type of public works they currently use.

Governments around the world provide financial incentives to encourage renewable energy generation and energy conservation. The primary goals of these efforts are to mitigate climate change and improve long-term energy independence by reducing reliance on fossil fuels. The consensus in the energy incentive literature is that performance-based incentives, which fund energy output, are more cost efficient than investment-based incentives, which fund capital input. This thesis uses a 30-year case study of Oregon's Business Energy Tax Credit (BETC) program to argue that investment-based energy incentives are moderately cost efficient relative to other state performance-based incentives and can be an effective driver of clean energy deployment. However, this analysis also finds that there are significant opportunities to improve the cost efficiency of investment-based energy incentive programs by targeting least cost projects. Namely, 50% of the first year kilowatt-hour electricity returns of the BETC program could have been achieved at 10% of the cost. These lessons from historical BETC spending should guide policymakers, NGO.s, and businesses who aim to make targeted use of fiscally-constrained energy incentive programs.

This thesis describes the role of cost effective maintenance in achieving competitive advantages. It explores by means of a survey which maintenance practices are used, and how maintenance policies are selected in Swedish industries. Also, it suggests a model for selecting the most cost effective maintenance policy, and how to improve the effectiveness of condition based maintenance decision-making. Finally it discusses how to assess the impact of maintenance practices on business strategic objectives. The main results achieved in the thesis are 1) A better understanding of maintenance organisation, management, systems and maintenance status in Swedish industry. For example, it was found that about 70% of Swedish companies still consider maintenance as a cost centre. Preventive and predictive maintenance approaches are also emphasised. 2) Most Swedish firms, i.e. about 81%, use the accumulated knowledge and experience within the company as a method for maintenance selection. Besides, about 31% use a method based on modelling the time to failure and optimisation. About 10% use failure mode effect and criticality analysis (FMECA) and decision trees and only 2% use multiple criterion decision-making (MCDM). However, the most used maintenance selection method is not the one most satisfactory to its users. Furthermore, about 30% use a combination of at least two methods. 3) A practical model for selecting and improving the most cost effective maintenance policy was developed. It is characterised by incorporating all the strengths of the four methods used in industry. 4) A mechanistic model for predicting the value of vibration level was verified both at the lab and in a case study. 5) A model for identifying, assessing, monitoring and improving the economic impact of maintenance was developed and tested in a case study. Thus it was proved that maintenance is no longer a cost centre, but could be a profit-generating function. To achieve competitive advantages, companies should do the right thing, e.g. use the most cost effective maintenance policy, and they should do it right, e.g. ensure that they have the right competence. Furthermore, they should apply the never-ending improvement cycle, i.e. Plan-Do-Check-Act, which requires identifying problem areas by assessing the savings and profits generated by maintenance and monitoring the economic impact of the applied maintenance policy. Thus, they would know where investments should be allocated to eliminate the basic reasons for losses and increase savings. The major conclusion is that proper maintenance would improve the quality, efficiency and effectiveness of production systems, and hence enhances company competitiveness, i.e. productivity and value advantages, and long-term profitability.

Die vorliegende kumulative Promotion umfasst drei veröffentlichte Publikationen, die im Rahmen der Berliner Borderline Versorgungsstudie (BBV-Studie) durchgeführt wurden. In Studie 1 wurde die effectiveness der ambulanten Dialektisch-Behavioralen Therapie (DBT) an N = 47 Patienten mit einer Borderline Persönlichkeitsstörung (BPS), die das DBT-Behandlungsjahr vollständig durchlaufen haben, untersucht. Im Prä-Post-Vergleich zeigten sich für die untersuchten Symptombereiche signifikante Veränderungen und die Effektstärken lagen überwiegend im mittleren Bereich. 77% der Patienten erfüllten nach einem Jahr DBT nicht mehr die diagnostischen Kriterien für eine BPS. In Studie 2 wurden die Krankheitskosten von N = 55 BPS-Patienten in dem Jahr vor der ambulanten DBT umfassend aus einer gesellschaftlichen Perspektive erhoben. Die durchschnittlichen Kosten lagen bei €26.882 (SD = €32.275). Davon gingen mit €17.976 (SD = €23.867) etwa 66% auf die direkten, mit €8.906 (SD = €15.518) knapp 34% auf die indirekten Kosten zurück. In Studie 3 wurden für die N = 47 DBT- compleater die Krankheitskosten im Jahr vor der Therapie mit denen während des DBT-Behandlungsjahres und mit denen während des ersten Katamnesejahres (N = 33) verglichen. Die durchschnittlichen Krankheitskosten lagen im Jahr vor der DBT bei €28.026 (SD = €33.081), während des DBT-Jahres bei €18.758 (SD = €19.450) und sanken innerhalb des Katamnesejahres weiter auf €14.750 (SD = €18.592). Die deutlichsten Kostenreduktionen zeigten sich im stationären Bereich. Hingegen konnten die indirekten Kosten kaum gesenkt werden. Insgesamt weist die vorliegende Promotion darauf hin, dass die ambulante DBT auch unter Versorgungsbedingungen in Berlin wirksam ist. Zudem besitzt die BPS auch in Deutschland eine hohe gesellschaftliche Relevanz. Die Krankheitskosten können deutlich gesenkt werden, wenn BPS-Patienten in einem DBT-Netzwerk behandelt werden. Hieraus ergeben sich erste Hinweise auf die Effizienz der ambulanten DBT.
This thesis includes three publications that were conducted as part of a Berlin wide treatment study (“Berliner Borderline Versorgungsstudie“). In study 1, we examined the effectiveness of dialectical behavior therapy (DBT) for borderline personality disorder (BPD) under the routine health care situation in Berlin. N = 47 patients completed the one-year treatment and provided data. Our findings demonstrate significant improvements on all measures with medium effect sizes. Moreover, at the end of the first treatment year, 77% of the patients no longer met the criteria for a BPD diagnosis. In Study 2, BPD-related cost-of-illness 12 months prior to outpatient DBT was assessed in a sample of N = 55 BPD-patients from a societal perspective. Total cost-of-illness was €26882 (SD = €32275) per patient. €17976 (SD = €23867; 66%) were direct costs and €8906 (SD = €15518; 34%) were calculated as indirect costs. In study 3, societal cost-of-illness of the N = 47 DBT completers was calculated for 12 months prior to DBT and further investigated during DBT-treatment year and during the following year. Total mean annual cost-of-illness was €28026 (SD = €33081) during pre-treatment, €18758 (SD = €19450) during the DBT treatment year and €14750 (SD = €18592) during the follow-up year for the N = 33 patients who participated in the final assessment. Cost savings were mainly due to marked reductions of inpatient treatment costs, while indirect costs barely decreased. In sum, the present thesis shows that outpatient DBT under routine mental health care conditions in Berlin leads to positive results. Furthermore, mean annual cost-of-illness of German BPD-patients exceed those of many other mental disorders meaning that BPD poses a high economic burden. Importantly, treatment of BPD patients with an outpatient DBT program is associated with substantial overall cost savings. Correspondingly, outpatient DBT has the potential to be an efficient treatment.

Mestrado Bolonha em Gestão e Estratégia Industrial
Com o aumento da competitividade dos mercados e simultaneamente rápida mudança dos mesmos, houve a necessidade de conseguir responder eficientemente a estas oscilações. De forma a conseguir responder eficientemente a esta volatilidade, desenvolveu-se a manufatura ágil, com o foco em produções flexíveis, altamente customizáveis e capazes de responder aos mais diversos requisitos dos clientes. No entanto, trata-se de uma abordagem complexa que obriga a uma adaptação por parte da empresa a uma escala estrutural, o que leva muitos gestores a questionar a sua viabilidade. Neste contexto, no presente estudo foi desenvolvido um modelo conceptual que relaciona a manufatura ágil com a capacidade de resposta aos clientes, a eficiência dos custos e a performance financeira. O modelo foi testado recorrendo a Structural equation modeling, mais especificamente, à metodologia Partial Least Squares (PLS), utilizando os dados obtidos de um questionário, previamente desenvolvido e realizado por inquérito a 298 empresas de manufatura portuguesa. Os resultados obtidos permitem concluir que as práticas de manufatura ágil tem um impacto direto na customer effectiveness e na performance financeira e afetam, ainda, indiretamente a cost efficiency, observando-se, assim, uma relação positiva e significativa com os diferentes desempenhos da empresa, podendo desta forma ser considerada uma mais-valia para as empresas de manufatura.
With the increase in the competitiveness of the markets and at the same time their rapid change, there was a need to efficiently respond to these fluctuations. To respond efficiently to this volatility, agile manufacturing was developed, with a focus on flexible, highly customizable productions capable of responding to the most diverse customer requirements. However, it is a complex methodology that requires the company to adapt to a structural scale, which leads to many managers questioning its viability. In this context, in the present study a conceptual model was developed that relates agile manufacturing to customer responsiveness, cost efficiency and financial performance. The model was tested using Structural equation modeling, more specifically, the Partial Least Squares (PLS) methodology, using data obtained from a questionnaire previously developed and carried out through a survey of 298 Portuguese manufacturing companies. The results obtained allow us to conclude that agile manufacturing practices have a direct impact on customer effectiveness and financial performance and indirectly affect cost efficiency, thus observing a positive and significant relationship with the different performances of the company, thus, it can be considered an asset for manufacturing companies.

La définition des priorités en matière de santé, dans le contexte de la couverture sanitaire universelle, met l'accent sur trois valeurs : améliorer la santé de la population, garantir l'égalité d'accès aux services et la qualité de ceux-ci et éviter l'appauvrissement des usagers ou la sous-utilisation des services par ceux-ci en raison de dépenses non remboursables. L’efficience allocative peut être mesurée par rapport à l'une quelconque de ces valeurs, ou par rapport à l'ensemble, par différentes variantes de l'analyse coût-efficacité. Dans cette thèse, nous utilisons la « Generalized Cost-Effectiveness Analysis », une approche normalisée développée par le programme « Choosing Interventions that are Cost-Effective » de l’Organisation Mondiale de la Santé, (WHO-CHOICE), qui peut être appliquée à toutes les interventions dans différents contextes. En utilisant cette approche, notre travail de thèse fournit une estimation quantitative de l'efficience allocative des ressources pour trois groupes de problèmes de santé : les maladies transmissibles, les maladies non transmissibles, les accidents de la circulation, en mettant l'accent sur deux régions économiquement et épidémiologiquement différentes : l'Afrique subsaharienne de l’Est et l'Asie du Sud-Est. Nos objectifs étant d’éclairer les débats sur les politiques de santé, d’améliorer le corpus mondial de connaissances sur le rapport coût-efficacité de différentes interventions en fournissant davantage d’informations sur l’efficience de l’allocation de ressources pour les trois groupes de problèmes de santé précités et de contribuer aux discussions sur l’élaboration des programmes de soins de santé universels
Priority setting in health, in the context of Universal Health Coverage, emphasizes three values: improving population health, ensuring equity in access to and quality of services and avoiding impoverishment or underutilization of services as a result of out-of-pocket expenditures. Allocative efficiency can be measured with respect to any one of these values, or with respect to all together by different variants of Cost-Effectiveness Analysis. In this thesis, we use the Generalized Cost-Effectiveness Analysis, a standardized approach developed by the World Health Organization’s programme, ‘Choosing Interventions that are Cost-Effective’ (WHO-CHOICE) that can be applied to all interventions in different settings. This thesis provides a quantitative assessment of allocative efficiency within three health categories: communicable diseases, noncommunicable diseases, and road traffic injuries, focusing on two economically and epidemiologically diverse regions: Eastern sub-Saharan Africa and Southeast Asia. Our objectives are to inform health policy debates, improve the world’s body of knowledge on the cost-effectiveness of different interventions by providing more information on the allocative efficiency in those three disease groups and contribute to discussions on Universal Health Care packages

Les procédés électrochimiques d'oxydation avancée constituent une technologie efficace pour traiter les produits pharmaceutiques car ils permettent la formation d'oxydants puissants tels que les radicaux hydroxyles capables d'éliminer presque tout type de contaminants organiques grâce à leur très haut pouvoir oxydant. Parmi eux, l’électro-Fenton et l’oxydation anodique sont des méthodes respectueuses de l'environnement car ils n'utilisent aucun réactif chimique (oxydation anodique) ou uniquement l'oxygène de l'air et des ions fer en tant que catalyseur (électro-Fenton).Dans cette thèse, quatre produits pharmaceutiques appartenant à des familles différentes ont été sélectionnés en fonction de leur toxicité et de leur présence dans les eaux de l'environnement. Leur élimination de l'eau a été effectuée par électro-Fenton. Les objectifs de ce travail étaient de déterminer (i) les meilleures conditions opératoires à l’échelle du laboratoire (courant et concentration du catalyseur), (ii) la cinétique de dégradation et de minéralisation et enfin (iii) de proposer une voie de minéralisation basée sur des intermédiaires aromatiques, des acides carboxyliques et des ions libérés dans la solution.Comme ces traitements ont été appliqués avec succès, un réacteur pilote composé alternativement d'anodes en BDD et de cathodes en feutre de carbone, doté d’un système d'aération et fonctionnant en mode continu a été construit pour évaluer la faisabilité d’un changement d’échelle et se diriger vers une pré-industrialisation du procédé. Différentes configurations d'électrodes ont été testées. Le débit et le courant se sont avérés être plus influents sur le taux de minéralisation et sur la consommation d'énergie, respectivement. Pour mieux comprendre le rôle du débit et des configurations, une étude hydrodynamique a été réalisée. Le modèle hydrodynamique a été associé à un modèle cinétique de minéralisation afin d'obtenir un modèle permettant de prédire le pourcentage de minéralisation à différentes positions à l'intérieur du réacteur en régime permanent. Ainsi, ce modèle peut aider à optimiser les conditions opératoires et à dimensionner les futurs réacteurs en fonction de l’objectif de minéralisation du traitement (taux de minéralisation élevé, traitement combiné, flux élevé,…).Afin de réduire les coûts opératoires, la combinaison d’un procédé électrochimique et d’un traitement biologique a ensuite été étudiée. Afin d’obtenir un traitement combiné efficace, il a été constaté que le traitement électrochimique devait (i) dégrader l'hydrochlorothiazide (ii) réduire de manière significative la concentration de ses intermédiaires aromatiques car ils inhibent de manière significative l'activité bactérienne, (iii) favoriser la formation de molécules biodégradables telles que les acides carboxyliques. La biodégradation de quatre acides carboxyliques formés lors du traitement par électro-Fenton de l'hydrochlorothiazide a également été étudiée. Il a été démontré qu'ils étaient dégradés de manière séquentielle avec différentes phases de latence et cinétiques de dégradation. Ainsi, pour les minéraliser, un réacteur de type «piston» est recommandé. La combinaison de traitement a ensuite été appliquée à un traitement électrochimique effectué à faible courant avec une anode en BDD et une anode en Platine. Un degré de minéralisation de 38 et 50% a été obtenu par le traitement biologique permettant d'atteindre un taux de minéralisation global de 66 et 85% avec les anodes en BDD et Platine respectivement. Ainsi, cette combinaison de traitement a été un succès, un changement d’échelle du procédé peut alors être envisagé
Electrochemical advanced oxidation processes (EAOPs) constitute an efficient technology to treat the pharmaceuticals as they allow the formation of strong oxidants such as hydroxyl radicals able to remove nearly any type of organic contaminants thanks to their very high oxidation power. Among them the electro-Fenton and anodic oxidation processes are environmentally friendly methods as they use no chemical reagent (anodic oxidation) or only oxygen of air and iron ions as a catalyst (electro-Fenton).In this thesis, four pharmaceuticals from different families and structures were selected based on their toxicity and their occurrence in environmental waters and their removal from water was performed by EAOPs. The objectives of this work were to determine the best operating conditions at lab scale (current and catalyst concentration), investigate the kinetic of degradation and mineralization and finally propose a mineralization pathway based on aromatic intermediates, carboxylic acids and ions released to the solution.As these treatments were successfully applied, a lab scale pilot reactor composed alternately of BDD anodes and carbon felt cathodes with a bottom aeration system and working in the continuous mode was built to scale-up these processes in order to pre-industrialize them. Different configurations of electrodes were tested. The flow rate and the current were found to be more influent on the mineralization rate and on the energy consumption, respectively. To deeper understand the role of the flow rate and the configurations a hydrodynamic study was performed. The hydrodynamic results were gathered with a kinetic model for the mineralization to obtain a model predicting the percentage of mineralization at different position inside the reactor during the steady state. Thus, this model can help to optimize the operating conditions and to size future reactors depending on the mineralization objective of the treatment (high mineralization rate, combined treatment, high flow, …).To reduce operating cost, the combination of an electrochemical process and a biological treatment was then investigated. In this frame, it was found that electrochemical treatment can (i) degrade the hydrochlorothiazide (ii) reduce significantly the concentration of its aromatic intermediates as they were shown to significantly inhibit the bacterial activity, (iii) promote the formation of biodegradable molecules such as carboxylic acids. The biodegradation of four carboxylic acids formed during the electro-Fenton treatment of the hydrochlorothiazide at lab scale was also studied. It was demonstrated that they were sequentially degraded with different lag phases and kinetics of degradation. Thus to mineralize them, a “plug flow” type reactor is recommended. The combination of treatment was then applied with an electrochemical treatment performed at low current with a BDD anode and a Platine anode. A mineralization degree of 38% and 50% were obtained by the biological treatment enabling to globally reach a mineralization rate of 66% and 85% with the BDD and the Platine anodes respectively. Thus this combined treatment was successful and open the way for the scale-up of these processes

Le législateur français a intégré le critère d’efficience dans la détermination du prix du médicament remboursable en 2012. L’efficience des médicaments doit être documentée pour les produits susceptibles d’apporter un bénéfice thérapeutique important et d’avoir un impact significatif sur les dépenses d’assurance maladie. Elle vise à mesurer le coût du gain marginal en santé produit par une intervention, par rapport au coût et à l’efficacité d’une autre intervention substituable. La thèse se situe dans une perspective d’analyse empirique des relations de délégation à l’œuvre dans la régulation du médicament, en vue de son accès au remboursement et de la fixation de son prix en France. Elle se fonde sur une analyse de trois applications de l’évaluation de l’efficience reflétant un approfondissement progressif de l’évaluation économique de l’intervention de santé dans trois contextes institutionnels distincts. Leur comparaison permet d’identifier les enjeux soulevés par la mise en œuvre de la régulation, les facteurs de son efficacité et les risques associés au regard du cadre théorique de la théorie des incitations en se posant successivement les questions suivantes : 1) L’information produite par le calcul économique expose-t-elle le décideur à un risque de manipulation de l’outil ? 2) L’apport du calcul économique est-il amélioré dans un processus d’évaluation contraint? 3) Des approches complémentaires peuvent-elles enrichir l’évaluation économique et en améliorer l’usage en révélant d’autres déterminants de la décision en santé? Les travaux de la thèse mettent en évidence l’apport du critère d’efficience pour améliorer l’information du décideur. Le risque, réel, de capture de régulation peut être limité par un processus d’évaluation plus transparent et par une explicitation des enjeux de la décision et des objectifs de la régulation
In 2012, cost-effectiveness has been formally introduced in the French legislation as a criterion to determine the price of prescription drugs. Cost-effectiveness is requested to claim for reimbursement of drugs expected to provide a therapeutic benefit and to have a significant impact on Social Insurance budget. Cost-effectiveness estimates the incremental cost and effectiveness produced by an intervention in comparison to other interventions that could have been used. The thesis is an empirical analysis of delegation relationships in the regulation of reimbursed drugs in France. The thesis analyses three different applications of cost-effectiveness evaluation to highlight the issues surrounding the use of economic calculation and the risks that are associated with it through three questions: 1) does the cost-effectiveness evaluation expose the regulator to regulation capture? 2) Is the contribution of the cost-effectiveness evaluation enhanced in a regulatory framed process? 3) Could complementary evaluations enrich cost-effectiveness evaluation and favour its usage via the clarification of the issues surrounding the decision? The thesis documents the benefit provided by the introduction of the cost-effectiveness criteria. The actual risk of regulation capture could be limited through a more transparent process of evaluation and through a clarification of the objectives of the regulation

Contexte. L’augmentation de la participation au dépistage organisé des cancers et la réduction des inégalités sociales et géographiques de participation représentent un enjeu de santé publique majeur. Objectifs. Evaluer l’efficience de 2 interventions visant à augmenter la participation et à réduire les inégalités dans le dépistage organisé des cancers en France. Méthodes. Nous avons réalisé une analyse coût-efficacité du point de vue du financeur: 1) d’une invitation à une unité de mammographie mobile (MM) dans le dépistage du cancer du sein à partir de données rétrospectives (n=37461), 2) d’un accompagnement personnalisé (AP) («patient navigation») dans le dépistage du cancer colorectal à partir d’un essai contrôlé randomisé (n=16250). Résultats. Le coût incrémentiel par dépistage supplémentaire comparé au dépistage habituel était: 1) de 611€ [492-821] pour l‘invitation au MM (+3.8% [2,8-4,8], +23.21€ [22.64-23.78]), et 2) de 1212€ [872-1978] pour l‘AP (+3.3% [1.5-5.0], +39.70€). L’efficacité et l’efficience étaient plus importantes dans les zones défavorisées et dans les zones éloignées pour le MM, alors qu’elles étaient moins favorables dans les zones défavorisées pour l’AP. Conclusion. La MM et l’AP peuvent réduire les inégalités en étant plus efficient dans les zones éloignées et les zones défavorisées pour la MM, alors que pour y parvenir, l’AP devrait cibler les sujets défavorisés, bien que n’étant pas la stratégie la plus efficiente. Les recherches doivent être poursuivies pour déterminer les conditions optimales de l’intégration du MM dans le dépistage, et pour améliorer l’efficacité et l’efficience de l’AP, qui ne peut être recommandé en l’état pour l’instant
Background. Increasing participation in organized cancers screening and reducing social and geographical inequalities in participation represent a major public health issue. Objectives. To determine the costeffectiveness of 2 interventions aiming at increasing participation and reducing inequalities in organized cancer screening in France Methods. We conducted a cost-effectiveness analysis from the payer's perspective: 1) of an invitation to a mobile mammography unit (MM) unit for breast cancer screening from retrospective data (n = 37461), 2) of a patient navigation program (PN) for colorectal cancer screening from a randomized controlled trial (n = 16250). Results. The incremental cost per additional screen compared with usual screening was: 1) € 611 [492-821] for the invitation to the MM (+ 3.8% [2.8-4.8], + € 23.21 [22.64-23.78] ), and 2) of € 1 212 [872-1 978] for PN (+ 3.3% [1.5-5.0], + 39.70 €). Effectiveness and cost-effectiveness were greater in deprived areas and in remote areas for MM, whereas they were less favorable in deprived areas for PN. Conclusion. MM and PN can reduce inequalities while being more efficient in remote areas and in deprived areas for MM, while, to achieve this, PN should target deprived people, even if being not the most efficient strategy. Research needs to be pursued to determine the optimal conditions for MM integration in organized breast cancer screening, and to improve the effectiveness and cost-effectiveness of PN, which can not be recommended as experimented for now

This study presents findings from survey and interview data investigating replication of green building measures by Commercial Building Partnership (CBP) partners that worked directly with the Pacific Northwest National Laboratory (PNNL). PNNL partnered directly with 12 organizations on new and retrofit construction projects, which represented approximately 28 percent of the entire U.S. Department of Energy (DOE) CBP program. Through a feedback survey mechanism, along with personal interviews, quantitative and qualitative data were gathered relating to replication efforts by each organization. These data were analyzed to provide insight into two primary research areas: 1) CBP partners' replication efforts of green building approaches used in the CBP project to the rest of the organization's building portfolio, and, 2) the market potential for technology diffusion into the total U.S. commercial building stock, as a direct result of the CBP program. The first area of this research focused specifically on replication efforts underway or planned by each CBP program participant. The second area of this research develops a diffusion of innovations model to analyze potential broad market impacts of the CBP program on the commercial building industry in the United States. Findings from this study provided insight into motivations and objectives CBP partners had for program participation. Factors that impact replication include motivation, organizational structure and objectives firms have for implementation of energy efficient technologies. Comparing these factors between different CBP partners revealed patterns in motivation for constructing energy efficient buildings, along with better insight into market trends for green building practices. The optimized approach to the CBP program allows partners to develop green building parameters that fit the specific uses of their building, resulting in greater motivation for replication. In addition, the diffusion model developed for this analysis indicates that this method of market prediction may be used to adequately capture cumulative construction metrics for a whole-building analysis as opposed to individual energy efficiency measures used in green building.

The closed-type plant factory (PF) is the highest-level horticulture facility. By providing artificial environment for plants, it can reach the stable quantities as a goal in the whole year. However the cost and energy of PF initial construction are high, they lead to higher costs when it compares to Open field agriculture. Therefore, reducing the cost and enhance the efficiency become the most important goals for the PF. The study has three ways to investigate. First, use different daily light integral in lettuce seedling. Second, adjust light intensity and CO2 concentration according to the lettuce condition. Third, the best proportion of concentration of nutrition and water replacing in hydroponics. We hope these three ways can enhance the resource usage efficiency of light, CO2 and nutrient solution. First part is using different daily light integral in lettuce seedling. We hope that when we supply more photons, it can increase the lettuce weight and can enhance the growth in usage light efficiency. As a result, using different photons can increase lettuce weight and light efficiency in lettuce seedling. However, different treatments have the same growth rate in 4 weeks. It is mean that its effect cannot remain at the later period. Also, the light period has 24 hours in seedling; it can decrease light usage efficiency when planting the later period. Second part is depending on lettuce photosynthetic rate to give different light intensity and CO2 concentration. When the photosynthetic rate is increasing, we will supply more resource to accelerate the production. When the photosynthetic rate is decreasing, we will reduce light and CO2 resource. By this way, we can reduce the cost and enhance the efficiency. In the result, the varied treatment is depending on lettuce photosynthetic rate have the heaviest fresh weight of treatments (light-prior or CO2-prior). The cost per 100g lettuce in varied treatment was lower than the other treatments. It can reduce cost 10% - 24%. In the light use efficiency, the varied treatment has the same value with CO2-prior. It proved the proposed strategy which is based on plant demand. And it could improve the yield and decrease the operating cost effectively. Third part is nutrient solution usage effectively. This part contains two approaches. One is using different electrical conductivity on lettuce and discusses the influence of it. The other is using different replacement quantity of nutrient solution in hydroponics. In the continuous planting, we find the relationship between calculating the ion by putting it and the lettuce fresh weight to find the best nutrient solution usage effectively. As a result, the different electrical conductivity has no significant differences in Yamasaki nutrient solution. It is appropriate for lettuce that electrical conductivity is 1.0 mS cm-1 in Yamasaki nutrient solution. When nutrient solution was planted lettuce at three times, lettuce fresh weight and ion absorption were decreasing. When we continuous plant them, the electricity illumination and nutrient solution cost will increase. Replacing all nutrient solution will be the best usage efficiency. However, considering environment effect, we don’t suggest to replace all nutrient solution. It is an appropriate treatment for only replacing 50% nutrient solution.

Annotation:

The topic of emission reduction has been a big concern in Europe as, although the emissions of pollutants have been decreasing, air pollution remains a problem. The present work aims to bridge the existing gap on the literature, finding spatially distributed solutions that achieve the emissions targets imposed by the National Emission Ceilings Directive (NEC) for 2030, using Portugal as a case study. The main objective of this dissertation is to find technologies that can achieve Portugal's NEC in a cost-effective way. For this purpose the identification of the most crucial sector activity categories regarding the emissions and the identification of the cheapest technologies that will enable the achievement of the targets, through the GAINS model database in activity level, emissions and costs by technology was performed, as well as the identification of the areas of Portugal for which those measures should be applied to achieve the target in a cost-effective way through the EESIP-Air model application, using spatially distributed emission data taken from EMEP. This work provides essential information to support and define an integrated strategy to fulfil NEC. Results show that the areas of Portugal with the highest levels of pollutant emissions are the west coast, with an incidence in the urban areas of Porto and Lisbon and, concerning NH3, also the areas of Alentejo and Trás-os-Montes (agricultural areas). NOx is the pollutant for which CLE2030 simulations are closer to the ceiling due to the measures related to the transport sector (European emission standards) so that, the extra effort to be done is not as relevant as for the other pollutants - NH3, SO2, NMVOC and PM2.5. Scenario OPT2030 led to the best solutions to achieve the NEC targets (43 kt/year for NH3, 95 kt/year for NOx, 27 kt/year for PM2.5, 30 kt/year for SO2 and 132 kt/year for VOC), allowing the reduction of the emission in 14% (NH3), 25% (NOx), 45% (PM2.5), 35% (SO2), and 21% (NMVOC) comparing with the scenario CLE2015. The costs obtained for each scenario are: 543 m€/year (CLE2015), 509 m€/year (CLE2030) and 518 m€/year (OPT2030). OPT2030 implies an increase in 2% relative to the cost for scenario CLE2030, however it represents the minimum required to achieve the NEC targets.
O tema da redução de emissões tem sido uma grande preocupação na Europa pois, embora as emissões de poluentes tenham diminuído, a poluição do ar continua a constituir um problema. O presente trabalho tem como objetivo preencher a lacuna existente na literatura, encontrando soluções espacialmente distribuídas que atinjam as metas de emissões impostas pela Diretiva Tetos de Emissão Nacional (TEN) para 2030, usando Portugal como estudo de caso. O principal objetivo desta dissertação é encontrar tecnologias que permitam atingir os tetos para Portugal ao mais baixo custo. Para esse fim, foram identificadas as categorias de atividades mais relevantes de cada setor em relação às emissões e as tecnologias mais baratas que permitirão o alcance das metas, recorrendo à base de dados do modelo GAINS sobre nível de atividade, emissões e custos por tecnologia. Foram também identificadas as áreas de Portugal para as quais essas medidas devem ser aplicadas de forma a atingir os objetivos de forma económica através da utilização do modelo EESIP-Air, usando dados de emissões espacialmente distribuídos retirados do EMEP. As áreas de Portugal com emissões de poluentes mais elevadas são a costa oeste, com incidência nas áreas urbanas do Porto e Lisboa e, no que diz respeito ao NH3, também as áreas do Alentejo e Trás-os-Montes (áreas agrícolas). O NOx é o poluente para o qual as simulações do cenário CLE2030 estão mais próximas do teto devido às medidas adotadas no setor de transportes (normas europeias de emissão), de modo que o esforço extra a ser feito não é tão relevante quanto para outros poluentes NH3, SO2, NMVOC e PM2.5. O cenário OPT2030 apresentou as melhores soluções para atingir os TEN (43 kt / ano para NH3, 95 kt / ano para NOx, 27 kt / ano para PM2,5, 30 kt / ano para SO2 e 132 kt / ano para VOC), permitindo a redução da emissão em 14% (NH3), 25% (NOx), 45% (PM2,5), 35% (SO2) e 21% (NMVOC) em comparação com o cenário CLE2015. Os custos obtidos para cada cenário são: 543 m€ / ano (CLE2015), 509 m€ / ano (CLE2030) e 518 m€ / ano (OPT2030). O OPT2030 implica um aumento de 2% em relação ao custo do cenário CLE2030, no entanto, o mínimo necessário para atingir os TEN. Este trabalho fornece informações essenciais para apoiar e definir uma estratégia integrada para atingir os TEN.

Highway bus operators in Taiwan have been receiving subsidy from the government Since October 1996. To evaluate the effects of subsidy, we have to investigate the variation in performance before and after the subsidy. This paper uses DEA (Data Envelopment Analysis) method to evaluate the performance index of cost efficiency and service effectiveness. CCR models for both cost efficiency and service effectiveness are constructed using 1996 (before subsidy) and 1997 (after subsidy) data. The efficiency and effectiveness analysis, slack analysis, and sensitivity analysis, are conducted to compare the differences before and after the subsidy. In addition, we construct the productivity change model, using the data from 1995 to 1997, to compare the shift in technology, catching-up in efficiency, and change in total efficiency. Finally, we test cost efficiency and service effectiveness of the whole industry to see whether there exists significant difference before and after the subsidy For the whole industry, the result shows that there is no significant difference in cost efficiency and service effectiveness before and after the subsidy. For the operators, the performance of Yuan Lin Bus before subsidy and Yi Shin Bus after subsidy are the best companies in cost efficiency. Dam Shui Bus, Yi Shin Bus, Ding Dong Bus, and Tainan Bus have made good progresses after subsidy. Miao Li Bus and Pain Hu Bus are the best companies in service effectiveness. The result of productivity change model shows that, Taipei Bus, Dam Shui Bus, Yi Shin Bus, Nan Tou Bus,Chia Yi Bus and Ding Dong Bus are the best ones in cost efficiency whose DEA values were 1 in 1997, and they kept progresses from 1995 to 1997. However, all operators did not performed very well in service effectiveness except for Miao Li Bus and Chia Yi Bus who made slight progresses in recent three years.

Technological systems are not merely designed with a narrow function in mind. Good designs typically aim at reducing operational costs, e.g. through achieving high energy efficiency and improved dependability (i.e. reliability, availability and maintainability). When there is a choice of alternative design options that perform the same function, it makes sense to compare alternatives so that the variant that minimises operational costs can be selected. In this paper, we examine this issue in the context of the design of Waste Heat Recovery Systems (WHRS) for main engines of large commercial freight vessels. We propose a method that can predict the operational cost of a WHRS via thermodynamic analysis which shows costs related to energy utilisation, and dependability analysis which shows costs related to system unavailability and repair. Our approach builds on recent advances in thermodynamic simulation and compositional dependability analysis techniques. It is a model-based approach, and allows reuse of component libraries, and a high degree of automation which simplify application of the method. Our case study shows that alternative designs can be explored in fast iterations of this method, and that this facilitates the evidence-based selection of a design that minimises operational costs.

This paper discussed the efficiency and cost-effectiveness of ISV (in-situ vitrification) technology applied on remediation of illegal waste dumping sites. Waste/soil samples from several illegal waste dumping sites in southern Taiwan were used for testing and evaluation. The stability and weather durability of vitrified samples were evaluated through reviewing test results of physical-chemical characteristics and TCLP analysis, the structure of vitrified samples was analyzed by means of SEM、EDS and XRD. The results of TCLP showed that the heavy metal concentration in leachate from vitrified samples is far below regulatory limits, this is probably because heavy metal elements were encapsulated or bonded in matrix structure of vitrified samples. The density of vitrified samples ranged from 2.46 to 2.65 g/cm3, hardness of all samples is no less than 7, which means that waste/soil becomes denser, harder and less volume after vitrification. ISV technology was recommended by this paper because it can make waste/polluted-soil more stable, weather durable and, therefore, resourcing material.

The Lower Athabasca Water Management Framework limits water extractions by the oil sands industry near Fort McMurray, Alberta. To increase water-use efficiency and minimise the cost of water restrictions, several policy and technology options were developed and assessed using quantitative and qualitative methods. Selected options were the policies of water trade and pricing with refund, and the technologies of storage, and consolidated tailings and increased recycling. Options were designed based on year 2020 demand and assessed relative to prior allocation. Using linear programming and static optimisation, it is shown that an off-stream storage sized to avoid water restrictions, in combination with efficient water allocation (e.g. water trade), is most cost-effective, although provides no ongoing incentive to increase water-use efficiency. Only the policy options provide equal incentives across firms to increase efficiency. To achieve both objectives of increased water-use efficiency and minimised costs, a combined policy and technology approach is recommended.
