Thesis (MComm (Logistics))--University of Stellenbosch, 2011.
ENGLISH ABSTRACT: Mobile phone networks form an integral part of economic and social development globally. Mobile phones have become an everyday part of life and it is hard to imagine a competitive economy without the availability of mobile communications. Emerging markets benefit most from the implementation of mobile technology and growth trends are outperforming earlier predictions. The most popular and sustainable payment model used by mobile phone networks in emerging markets is the pre paid mechanism used for the distribution of airtime. This mechanism brings about unique challenges for networks in emerging markets. In this thesis the importance of the mobile phone network pre paid value channel is introduced through an analysis of pre paid revenue. A brief introduction is given to the systems and products that contribute to the functioning of the pre paid value channel. The revenue generation process is described with regards to the pre paid sector of the market and an in-depth explanation of the importance of deferred revenue is given, how it is recorded and what role it fulfils in the generation of revenue. The complexity of the network environment, both technical and operational makes the use of a business automation and support system (BSS) a necessary tool for effective execution of tasks and processes within the network environment. These systems record information from a wide spectrum of available technical network resources and use this information to automate the flow of network products. The use of such a system for the calculation of deferred revenue is suggested. Saaty‟s Analytical Hierarchy Process (AHP) algorithm and the Elimination and Choice Expressing Reality (ELECTRE) method are used to compare the newly proposed method for the calculation of deferred revenue using a BSS. Using Saaty's algorithm to estimate the effectiveness of deferred revenue as reported through the use of a BSS yields favourable results for the proposed method. This helps to bridge the gap in the poorly researched mobile telecommunications industry. ELECTRE is used to substantiate the findings of the model using AHP and meaningful tests are done to motivate correctness and accuracy of the results obtained throughout. Most importantly, the findings were shared with academic and industry experts, adding meaningful resemblance to the goals set out to achieve.
AFRIKAANSE OPSOMMING: Mobiele foon netwerke is wêreldwyd 'n onlosmaakbare deel van ekonomiese en sosiale ontwikkeling. Mobiele fone is deel van ons alledaagse lewe en dit is moeilik om 'n kompeterende ekonomie te bedink sonder die beskikbaarheid van mobiele kommunikasie. Ontluikende markte trek die meeste voordeel uit die implementering van mobiele tegnologie en groeitendense vertoon beter as wat vroeër voorspel is. Die mees gewilde en volhoubare betaalmetode wat deur mobiele foon netwerke in ontluikende markte gebruik word, is die voorafbetalingsmeganisme wat vir die verspreiding van lugtyd gebruik word. Hierdie meganisme bring unieke uitdagings vorendag in ontluikende markte. Die tesis beskryf die belangrikheid van die mobiele foon netwerk voorafbetalingswaardekanaal deur 'n analise te maak van vooruitbetalingsinkomste. 'n Kort oorsig oor die sisteme en produkte wat bydra tot die funksionering van die vooruitbetalingswaardekanaal word verskaf. 'n Beskrywing van die inkomste-genereringsproses vir die vooruitbetaling-sektor van die mark word verskaf en 'n in-diepte verduideliking van die belangrikheid van uitgestelde inkomste, hoe dit vasgelê word en watter rol dit speel in die generering van inkomste word verduidelik. Die kompleksiteit van die netwerkomgewing, beide op 'n tegniese en operasionele vlak, maak die gebruik van 'n besigheidsoutomatisering en ondersteuningsisteem (BSS) 'n noodsaaklike instrument vir die effektiewe uitvoer van take en prosesse binne die netwerkomgewing. Hierdie sisteme stoor informasie vanuit 'n wye spektrum van beskikbare tegniese netwerkbronne en gebruik die inligting om die vloei van netwerkprodukte te outomatiseer. Die gebruik van sodanige sisteem word voorgestel vir die berekening van uitgestelde inkomste. Saaty se Analitiese Hierargie Proses-algoritme (AHP) en die Eliminasie en Realiteit-Deur-Keuse Uitdrukkingsmetode (ELECTRE) word gebruik vir die vergelyking van die voorgestelde metode vir die berekening van uitgestelde inkomste deur middel van 'n BSS. Die gebruik van Saaty se algoritme om die effektiwiteit te bereken van uitgestelde inkomste soos gemeld deur die gebruik van 'n BSS, lewer gunstige resultate vir die voorgestelde metode. Dit vul 'n leemte in die swak nagevorsde mobiele telekommunikasie industrie. ELECTRE word gebruik om die bevindinge van die AHP-model te substansieer en betekenisvolle toetse word deurentyd gedoen om die korrektheid en akkuraatheid van die resultate te motiveer. Die belangrikste aspek van die navorsing is dat die bevindinge gedeel is met kenners binne die akademie sowel as die industrie, wat nou aansluit by die doelstellings wat aanvanklik beoog is.

For the last decades, numerous researchers have studied housing preferences of populations. However, very few researchers put highlight on young adults in Sweden and their housing preference. From a Swedish perspective, it is worthwhile to investigate housing preferences of young adults as the populationof young adults is consistently growing and their roles as dynamic consumers are crucial in the housing market. This thesis aims to examine housing preference of young adults aged 18 to 30 in largest cities in Sweden by comparison to older age groups. By identifying housing attributes highly valuedby the young adults, the research shall provide guideline to practitioners withfuture housing development to attract the young generation. The research is a quantitative study with application of a survey method. Analytic hierarchy process (AHP) method forms a foundation of thequestionnaire design, enabling to observe young adults’ trade-off decisionsamong multiple housing attributes. Total 767 responses are collected and the responses with valid consistency ratio (CR) are selectively used in the analysis.The result demonstrates that young adults have high preference for ‘low price’,‘proximity to public transportation’, ‘balcony’, ‘feeling of safety’ and ‘proximity to work or school’ in a housing decision. On the contrary, they show little interest in ‘neighborhood environment’ and ‘sustainable aspects’ of an apartment in general. In comparison with older age groups, young adults have higher preference for the proximity of an apartment and having a dishwasher;yet their preferences for ‘cleanliness’, ‘green space’ and ‘separate kitchen’ of adwelling are lower than the older generation. The practitioners shall keep these findings in mind when planning and designing apartments for the young consumers.
De senaste decennierna har åtskilliga forskare undersökt boendepreferenser hos befolkningen i ett flertal olika länder. Trots detta finns det väldigt fåforsknings-rapporter som sätter fokus på unga vuxna i Sverige och derasboendepreferenser. Ur ett svenskt perspektiv är det viktigt att undersökaboendepreferenserna för denna folkgrupp. Detta eftersom unga vuxnas befolkningen konstant växer och deras dynamiska roll som konsumenter är livsviktiga för bostadsmarknaden. Denna rapport siktar på att, genomjämförelse med äldre åldersgrupper, undersöka boendepreferenser hos unga vuxna mellan 18 och 30 som bor i Sveriges största städer. Genom att identifierade egenskaper som är högt värderade av de unga vuxna, ämnar forskningen attge riktlinjer till framtida bostadsutveckling för att attrahera den unga generationen. Denna studie är av typen kvantitativ forskning, med surveyundersökning som vetenskaplig metod. Den metod som utformningen av frågeformulären bygger på är analytic hierarchy process (AHP). Metoden används för att observera unga vuxnas avvägning kring många olika boendeegenskaper. Totalt är 767 svarinsamlade varav de svar som har en giltig consistency ratio används i analysen.Resultatet visar att unga vuxna starkt föredrar egenskaper som ‘lågt pris’,‘närhet till kollektivtrafik’, ‘balkong’, ‘säkerhetskänsla’ och ‘närhet till skola eller jobb”. Vidare visar undersökningen att egenskaper som ”grannskapsmiljö”och ”hållbarhetsaspekter” generellt inte prioriteras högt. Vid jämförelse medäldre åldersgrupper har unga vuxna större intresse av lägenhetens läge samt ifall lägenheten har diskmaskin. Unga vuxnas preferenser för ‘renhet’, ‘grönaytor’ och ‘separat kök’ är däremot lägre än preferenserna kring sammaegenskaper hos de äldre generationerna. Bostadsutvecklare borde väga in dessa upptäckter vid planering och design av lägenheter för unga konsumenter.

Este trabalho descreve um experimento sobre o processo de decisão para priorização de projetos de melhoria em uma indústria de bens de capital. Apenas dois critérios eram aplicados na tarefa de priorizar projetos; exigências legais e complexidade técnica, então, foi proposto avaliar os projetos através de um conjunto mais amplo de critérios, incluindo imagem da marca, participação de mercado, alinhamento estratégico, tempo de lançamento de um novo produto. Para lidar com um número maior de critérios qualitativos e quantitativos, foi introduzido desde então, dois métodos multicritérios, a saber: o uso do AHP (analytical hierarchic process) e o DS-AHP (Dempster-Shafer /AHP). Os fundamentos teóricos dos dois métodos são apresentados. O primeiro método é usado para determinar as importâncias relativas das alternativas, por meio de ponderações em cada nível da estrutura hierárquica; a qualidade dos julgamentos é avaliada por um \"índice de consistência\". O segundo método também utiliza a plataforma de análise do AHP acrescentado mensuração da ignorância no processo de julgamentos por meio de probabilidades subjetivas. São comentadas as aplicações dos métodos em uma específica indústria. Foram observadas objeções dos decisores à aplicação do processo AHP, decorrentes da necessidade de numerosas re-avaliações dos julgamentos, quando o \"índice de consistência\" apresentava-se maior que os valores recomendados. Como ponto positivo foi destacada a simplicidade do método para aplicações no ambiente empresarial. Quanto ao método DS-AHP, o uso do conceito de crença nos julgamentos dos decisores, permitiu melhores aproximações às situações reais; neste caso, a alternativa eleita pôde ser claramente compreendida como a mais provável, e não classificada como provavelmente ou certamente a melhor. O DS-AHP quandocomparado ao AHP apresenta-se como um ferramental de condução mais direta para a obtenção dos resultados principalmente no que se refere ao menor número de comparações exigidas, também ajuda o decisor a identificar e corrigir as possíveis fontes de ignorância, que podem afetar a qualidade da decisão.
This study describes an experiment about the definition of portfolio of improvement projects in an industry of capital goods, which had until recently been prioritized based mainly on legislation demand and technical complexity. It was proposed to increase the criteria numbers including: market image, market share, strategic alignment, launch time to new products. To handle several criteria with focus quantitative and qualitative aspects was necessary introduced two multcriterial methods, namely, analytical hierarchic process (AHP) and Dempster-Shafer AHP process (DS-AHP). The first referred method is used to manage the relative importance of alternatives regarding the fore mentioned criteria based on weights attributed to structure hierarchical levels. The second referred method also uses AHP platform to enable ignorance measurement based on subjective probabilities. Results from direct application of the methods in this specific industry are commented. It was observed that the decision makers have some objections with respect to the AHP process, in the sense that there were judgment inconsistencies which required additional evaluation of the candidate solutions, what was seen as somewhat tiresome. The main advantages which was emphasize by decision makers refers to the ease of application in corporate environmental . As for the DS - AHP process, the possibility of considering believes in a structured way was felt as more appropriated to the real decision process, which effectively involves uncertainties. In this way, the elected alternative can be clearly understood as most probably - and not certainly - the best. Also the DS-AHP process was seen as more directly conducive to the final results in comparison with the AHP process.

ABSTRACTNowadays the importance of environmental logistics is increasing while organizations are trying to pay more attention to their transport activities. Since PNL is a famous logistics company in Nordic countries and transport activates are done by sub contractors they intend to make sound environmental choices by assessing their suppliers from environmental performance in order to identify the best suppliers which is comply with the PNL environmental policy.In this project the survey study and questionnaire has been made in order to evaluate the supplier performance from environmental perspective. At first the investigation has been made for improving the previous questionnaire which was made by PNL. Some parts were revised according to researchers‟ knowledge, reliable references and suggestion of environmental consultant. Lots of study has been made in order to find the most importing effects that can affect environmentalism. Obtained results from questionnaire were analyzed and appropriate suggestions were given in order to enlighten the significant importance of environmental issues.Due to complexity of decision making environment, the applicable and reliable method should be applied to cope with complexity and the factors that can affect the objective while simplifying the process. Analytical Hierarchy process has been applied for this project in order to change the qualitative situation into quantitative manner to rate the suppliers based on their performance.The first step in AHP process is constructing hierarchy in two or more level for evaluating the alternatives. The goal of the project is environmental performance .Second level is criteria which has been made according to literature and the importance of them while the suggestions of consultant has been applied as well. Third level is sub criteria which are questions of questionnaire and finally the forth level include alternative which is suppliers.Next step in AHP process is weighting criteria and sub criteria and making pair wise comparison between them. Procedure of weighting is done by researchers and managers from PNL in order to decrease the subjectivity of decision making process. The result from suppliers has been investigated and points were given to them according to their performance and ability regarding environmental logistics.Sensitivity analysis was made for analyzing the result from AHP in order to investigate the responsiveness of the result.Key words: Logistics, Environmentalism, AHP Method, Supplier Assessment, Survey Study.

Den spanska fastighetsmarknaden är på uppgång då fastighetspriserna ökar igen efter den globala finanskrisen 2008. Den här uppsatsen syftar både till att lösa ett fabricerat investeringsproblem med hjälp av AHP, Analytical Hierarchy Process, och till att undersöka hur processen av ett fastighetsköp som EU-medborgare kan se ut gällande lagar och regler.  Investeringsproblemet består utav att välja en av tre fastigheter, alla radhus med olika egenskaper lokaliserade i olika delar av Valencia på den spanska östkusten, baserat på resultatet från en  enkätundersökning utförd på plats i staden med ett urval om 70 respondenter i åldrarna mellan 20-29 år. Faktorerna som påverkar beslutet har delats in i tre huvudgrupper baserade på fastighetsvärdering; Lägesfaktorer, Byggnadsfaktorer och Ekonomiska faktorer. Lägesfaktorerna är sedan uppdelade i Avstånd till kusten och Avstånd till stadens centrum. Byggnadsfaktorerna i befintlighet av Terrass, Garage eller Kök med öppen planlösning. Slutligen består de Ekonomiska faktorerna endast av en faktor som är Pris, det annonserade priset €/m2. Enkätundersökningen kunde konstatera att en fastighet nära kusten föredras över en nära stadens centrum, 57 % över 43 %. Att Terrass var överlägset den viktigaste byggnadsfaktorn med en prioritet på 63 %, Garage  24 %, och att Kök med öppen planlösning inte prioriteras med endast 13 %. Huvudgrupperna prioriterades som följande; Lägesfaktorer 41,4 %, Ekonomiska faktorer, e.i. Pris, 34,3 %, och Byggnadsfaktorer 24,3 % - vilket är i linje med teori på området.  Resultaten från enkätundersökningen applicerat på AHP-modellen tillsammans med lokala prioriteter från jämförelsematriser visade att en av de tre fastigheterna rankas som mest effektiv. Det kontaterades vara det tredje objektet, ett radhuset nära stranden, som var att föredra med 55 % i global prioritet, följt av det första objektet med 26 % och sist det andra objektet med 19 %.  Uppsatsen konstaterar också att anlita en tredje part kan undvikas om man känner sig bekväm med övriga kontakter då de obligatoriska avgifterna för advokat, notarie och transaktionsskatt redan adderar 10-15% utöver köpeskillingen. Att processen att endast köpa en fastighet är relativt simpel, då det tekniskt sett endast är N.I.E-nummer krävs, men att det krävs betydligt mer att bli skatteresident och kunna ta del av skattemässiga lättnader. Slutligen diskuteras att med sina stigande fastighetspriser, sin enorma utvecklingspotential, det varma klimatet och den inkluderande mentaliteten hos folket kan Spanien vara en plats väl värt att investera i.
The Spanish housing market has been on the rise since 2014 as property prices are increasing again after the global financial crisis of 2008. This paper aims to both solve an illustrated investment problem using the decision making method AHP, Analytical Hierarchy Process, and to investigate the process of property investment in Spain as an E.U. resident concerning rules and regulations. The investment problem consists of selecting one out of three properties, all town houses with different characteristics, located in different parts of the city Valencia on the Spanish east coast based on the results of a survey done on site in Valencia with a sample of 70 respondents in the ages between 20-29 years.  The factors that influence the decision are based on property valuation; Localization factors, Technical building factors and Economic factors. The Localization factors are further divided into Distance to the city center and Distance to the cost. The Technical building factors in Terrace, Garage and Open-plan kitchen. Lastly the Economic factors only consist of one factor which is Price, the advertised price €/m2.The survey concluded that a property close to the cost is preferred over one close to the city center, 57 % over 43 %. That Terrace is the absolute most important building factor with a priority of 63 %, followed by Garage at 24 % and that Open-plan kitchen is not prioritized with only 13 %. The three main groups were prioritized as follows; Localization factors 41,4 %, Economic factors, i.e. Price, 34,3 %, and Technical building factors 24,3 % - which is consistent with theory on the subject.The results of the survey applied to an AHP hierarchy together with the local priorities from the application of the Saaty-scale and comparison matrices, result in one out of the three properties being ranked as the most efficient. It was concluded that the third property, a townhouse close to the beach, was preferred with a 55 % in global priority, followed by the first property with 26 % and lastly the second with 19 %. The paper also concludes that hiring a third party is something to consider avoiding if one feels comfortable with other contacts as the obligated lawyer, clerk and transaction fees already adds on 10-15% of the purchase price. That the process of only purchasing a property is relatively easy, as technically only N.I.E number is required, but that it requires significantly more to become resident to obtain tax benefits. Lastly the project discusses that with its rising property prices, development opportunities, the warm climate and the mentality of the people Spain certainly can be somewhere worth investing in.

Prioritizing software requirements helps to determine which requirements that are most important,and in which order requirements should be developed and tested throughout the development lifecycle. By prioritizing the requirements, software engineers can put focus on a subset of all requirements, and implement these in a particular release. This thesis aims to analyze two ratio scale prioritization techniques in a controlled experiment.The experiment was designed to compare time consumption, scalability, accuracy, ease of use, and ease to learning between the two techniques. All these evaluation parameters are combined together to find out which technique is more suitable to use when prioritizing software requirements. The two techniques investigated in the study presented in this thesis are: Analytical Hierarchy Process (AHP), which is based on pair-wise comparisons; and Cumulative Voting (CV) which is based on distributing points between requirements. The results of the experiment indicate that CV is less time consuming than AHP, which makes it more scalable. Further, CV is regarded as easier to use, and easier to learn than AHP. In addition, the results show that CV is more accurate than AHP while measuring the perceived accuracy. However, no conclusions could be made regarding actual accuracy due to misinterpretations by the study participants.

Ventilation is a critical task in underground mining operation. Lack of a good ventilation system causes accumulation of harmful gases, explosions, and even fatalities. A proper ventilation system provides adequate fresh air to miners for a safe and comfortable working environment. Fans, which provide air flow to different faces of a mine, have great impact in ventilation systems. Thus, selection of appropriate fans for a mine is the acute task. Unsuitable selection of a fan decreases safety and production rate, which increases capital and operational costs. Moreover, pitch angle of fans&rsquo
blades plays an important role in fan&rsquo
s efficiency. Therefore, selection of a fan and its pitch angle, which yields the maximum efficiency, is an emerging issue for an efficient mine ventilation. The main objective of this research study is to provide a decision making methodology for the selection of a main fan and its appropriate pitch angle for efficient mine ventilation. Nowadays, analytical hierarchy process as multi criteria decision making is used, and it yields outputs based on pairwise comparison. On the other hand, Fuzzy Logic as a soft computing method was combined with analytical hierarchy process and combined model did not yield appropriate results
because Fuzzy AHP increased uncertainty ratio in this study. However, fuzzy analytical hierarchy process might be inapplicable when it faces with vague and complex data set. Soft computing methods can be utilized for complicated situations. One of the soft computing methods is a Neuro-Fuzzy algorithm which is used in classification and DM issues. This study has two phases: i) selection of an appropriate fan using Analytical Hierarchy Process (AHP) and Fuzzy Analytical Hierarchy Process (Fuzzy AHP) and ii) selection of an appropriate pitch angle using Neuro-Fuzzy algorithm and Fuzzy AHP method. This study showed that AHP can be effectively utilized for main fan selection. It performs better than Fuzzy AHP because FAHP contains more expertise and makes problems more complex for evaluating. When FAHP and Neuro-Fuzzy is compared for pitch angle selection, both methodologies yielded the same results. Therefore, utilization of Neuro-Fuzzy in situation with complicated and vague data will be applicable.

Since the emergence in the early 1990s, PPP options have become increasingly popular to the governments of both developed and developing countries. On average, US$ 95b are invested annually in the developing countries in the form of PPP options up until 2017. However, a mixed result is documented with respect to their performances. PPP arrangements include multiple stakeholders that have diverse interests associated with their particular affiliations, and accordingly the performance expectations of these stakeholders also differ. Traditional approaches to performance evaluation are unable to capture all of the expectations to be included in the process of PPP project evaluation. Hence, using appropriate performance indicators and analysing their relative importance in influencing the performance score of particular projects remains unexplored in the developing country context. Against this backdrop, this study examines current practices of PPP performance evaluation, develops a framework of weighted performance indicators for developing countries and applies the model in a number of PPP projects in Bangladesh. A mixedmethod approach has been used, which includes the analytical hierarchy process (AHP) for establishing weights of the key performance areas (KPAs) and associated indicators and a case study method for applying the developed model to selected PPP projects in Bangladesh. Results show that ‘financing’, ‘planning and initiation’ and ‘transparency and accountability’ are the most important KPAs in evaluating PPP performances in Bangladesh and ‘feasibility analysis’, ‘life cycle evaluation and monitoring’ and ‘optimal risk allocation’ are the most significant performance indicators. Unlike traditional performance evaluation methods, a prioritised set of performance indicators and KPAs for the PPPs of Bangladesh has been identified. The findings also reveal that sincere government commitment is relatively more important for the success of PPPs than the enactment of enabling legislation in the context of developing countries. This suggests more efforts are required to be employed by the host government to build confidence in the private partner selected for engagement in PPP arrangements. Furthermore, a framework for performance evaluation of power sector PPPs, based on the KPAs, has been proposed. This could be used for evaluating the performance of power PPPs in a more objective and systematic way in Bangladesh and other South Asian countries. Finally, the weighted process applied to the various performance indicators provides an improved understanding of the relative significance of KPAs and their component indicators. Attaching weights to the KPAs and performance indicators of PPPs, and applying those weights to derive individual project scores in a developing country context, especially in Bangladesh, represents an innovation and thus a contribution to the PPP performance literature. Awareness of the outcomes of the weighted performance evaluation process developed in this study could help project implementers and regulators prioritise their attention and resource allocation decisions related to achievement of performance improvement on the more significant key performance areas. The weighted process is expected to contribute to reducing biases of either perceived Likert scaled scores or only the weightings in PPP performance evaluation.

In general, the adoption and diffusion of Information Systems (IS) in agriculture industry is a neglected issue in academia, let alone the livestock sector. In livestock industry, Radio Frequency Identification (RFID) technology is currently used in order to ensure meat safety. Generally, the livestock supply chain involves a large number of people and organisations/farms. To ensure a successful animal-tracing system, the examination of the adoption behaviour of those stakeholders is worthwhile. So far, no initiative has been made by the researchers to investigate the adoption process and relevant factors in a livestock setting. This research aims to close this research-gap. Furthermore, the ultimate success of an innovation is dependent not just on the adoption but on its continued and extended use. Scholars have been investigating on adoption and continuance behaviour of an innovation but not in an integrated fashion.This current research has studied both the adoption and continued and extended usage behaviour of Australian livestock industry regarding RFID technology in a single framework. Moreover, the extension decision of an innovation is a continuous and complex process. It is not easy for farms to identify a correct extension application from many possibilities. As has not been done yet a Decision Support System (DSS), which is based on Analytical Hierarchy Process (AHP), is developed in this research aiming to aid farms to choose the best extension-project.It is assumed that the adoption factors in a mandatory environment would be different than that of in a voluntary environment. In literature, it is very rare to find a comparative study of the adoption factors of a single innovation in both voluntary and mandatory environments. This research studied the both environments.This research adopted the ‘mixed method’ methodology. Face-to-face direct interview with semi-structured questionnaire has been used for the collection of qualitative data. Data obtained from the field study have been analysed using NVivo software package. On the other hand, Partial Least Square (PLS)-based Structural Equation Modelling (SEM) technique has been used for analysing the quantitative data obtained from a national survey on the variables identified earlier from the qualitative method.The findings of this research confirmed that environmental factors, organisational factors, and technological factors influence the adoption of RFID technology in livestock industry. The continued use and extended use of RFID systems are dependent on satisfaction obtained from using the current system. Moreover, confirmation bridges the adoption and continuance; this is the stage which influences the further-use of an innovation after being adopted.This current research has both theoretical and practical implications. Investigating the adoption factors along with continued and extended use factors in a single framework is a unique initiative by far in literature. This research strengthens the adoption-diffusion research of IS by getting insights from the livestock sector. Using the factors and variables, obtained from the research to develop a practical decision making process (i.e., the DSS) is innovative. As practical implications, governments and other organisations that have the power to make an industry to adopt an innovation should consider the findings of this study for efficient policy development and implementation. Similarly, the innovation-vendors/manufacturers may look at the derived factors for a successful acceptance of an innovation. Finally, the DSS does have the merit to be made more extensive and used at farm level in order to assist the farm decision-makers to choose their extension projects.

This thesis investigates Enterprise Resource Planning (ERP) adoption and implementation in Service Sector Organisations (SSOs). ERP is a business management system that has emerged to support organisations to use a system of integrated applications to enhance their Information Technology (IT) infrastructures, enhance business processes and deliver high quality of services. Regardless of the fact that several other sector organisations have adopted and implemented ERP systems, its application in SSOs is rather inadequate. Among other reasons, two core rationales can be attributed to the latter fact – firstly, SSOs lack the sufficient knowledge, expertise and training to implement such sophisticated integrated systems and secondly, the top management lacks the ability to take appropriate decisions for ERP adoption and implementation. However, merely focusing on a number of factors influencing ERP adoption and implementation may not be suffice, as there is a need for a systematic decision-making process for adopting and implementing ERP systems in SSOs. The limited number of ERP systems’ applications in SSOs has resulted in inadequate research in this area with many issues, like its adoption and implementation requiring further exploration. Despite, the implications of ERP systems have yet to be assessed in SSOs, leaving ample scope for relevance and producing a unique piece of research work. Thus, the author demonstrates that it is of high importance to investigate this area within SSOs and contribute towards successful ERP adoption and implementation. This thesis makes a step forward and contributes to the body of knowledge as it: investigates factors influencing the decision-making process for ERP adoption and implementation in SSOs, prioritises the importance of factors influencing ERP adoption and implementation, evaluates ERP lifecycle phases and stages, maps the ERP factors on different phases and stages of the ERP lifecycle, and in doing so, to propose a model for ERP adoption and implementation in SSOs. The author claims that such an ERP adoption and implementation process in SSOs is significant and novel as: it extends established norms for ERP adoption and implementation, by including Analytical Hierarchy Process (AHP) technique for prioritising the importance of factors, thus, facilitating SSOs to produce more robust proposals for ERP adoption and implementation. The author further assess the proposed ERP adoption and implementation model by using a qualitative, interpretive, multiple case study research strategy. Findings from two case studies demonstrate that such a systematic approach contributes towards more robust decisions for ERP adoption and implementation and indicates that it is acceptable by the case study organisations. The thesis proposes, assesses and presents a novel model for ERP adoption and implementation in SSOs and contributes to the body of knowledge by extending the literature.

No atual momento histórico, diante das transformações aceleradas das paisagens, em que as dinâmicas da sociedade se interpenetram e, muitas vezes, se sobressaem às dinâmicas da natureza, a questão ambiental assume importância em vários campos do conhecimento, sobretudo, na Geografia. Em meio aos diversos trabalhos desenvolvidos no âmbito geográfico e ambiental, tem-se a erosão como um dos assuntos mais enfatizados. Neste contexto, o objetivo geral da tese foi analisar os principais elementos que influenciam na vulnerabilidade ambiental aos processos erosivos lineares (sulcos, ravinas e voçorocas) de parte dos municípios de Marabá Paulista-SP e Presidente Epitácio-SP. Sob a perspectiva teórico-metodológica do pensamento da complexidade, foram caracterizados os aspectos do relevo, declividade, solos, substrato rochoso, cobertura vegetal, curvatura da superfície e uso da terra, além da elaboração de documentos cartográficos em ambiente de Sistemas de Informação Geográfica, em especial, o mapa de vulnerabilidade ambiental aos processos erosivos lineares. Em virtude das possibilidades de integração dos dados e atribuição de pesos, o referido mapa foi realizado a partir da lógica fuzzy, especificamente, da Técnica do Processo Analítico Hierárquico (AHP), a qual proporcionou o mapeamento de maneira classificada: baixa (0.32%), média (65.15%), alta (34.45%) e muito alta vulnerabilidade (0.08%). A baixa vulnerabilidade está elencada às matas ciliares remanescentes. A média vulnerabilidade se localiza nos topos das colinas com declividades inferiores a 5%. O uso da terra predominante é a pastagem e os solos são, em sua maioria, desenvolvidos e arenosos. A alta vulnerabilidade está, principalmente, nas vertentes convexas e retilíneas, em que as inclinações podem alcançar 15%. A pastagem prevalece, todavia, verificou-se a expansão do cultivo de cana de açúcar e do solo exposto para seu consecutivo plantio. A muito alta vulnerabilidade apresenta-se nas vertentes côncavas, cuja curvatura favorece a convergência das águas pluviais e, portanto, o fluxo linear. Tal evento se intensifica perante às declividades acentuadas – superiores a 20% para a região. Combinado a estes atributos, sobre solos rasos tem-se o pastoreio intensivo do gado, o qual acelera a compactação do solo e acarreta a erosão, sendo uma das formas de degradação mais recorrente no Extremo Oeste Paulista. Assim, o presente estudo pode contribuir no sentido de orientar a implantação de medidas preventivas e corretivas de controle à erosão por intermédio do planejamento ambiental.
In the current historical moment, given the accelerated changes in landscapes, in which the dynamics of society interpenetrate and, often, exceed the dynamics of nature, the environmental issue assumes importance in several fields of knowledge, especially, Geography. Among the diverse assignments developed in geographical and environmental contexts, erosion is one of the most commonly emphasized subjects. Therefore, this thesis aimed to analyze the main elements that influence environmental vulnerability to linear erosive processes (rills, ravines and gullies) in parts of Marabá Paulista-SP and Presidente Epitácio-SP. From the theoretical-methodological perspective of thought complexity, the relief, slope plans, soils, bedrocks, vegetation, surface curvature and land use aspects were characterized, in addition to the elaboration of cartographic documents using the Geographic Information System, in particular, the map of environmental vulnerability to linear erosive processes. Due to the possibilities of integrating data and assigning weights, the map was performed based on fuzzy sets, specifically, the Analytical Hierarchy Process (AHP), which provided classified mapping: low (0.32%), medium (65.15%), high (34.45%) and very high vulnerability (0.08%). The low vulnerability is identified in the reminiscent cilliary forests. The medium vulnerability is located on the hilltops with slopes of less than 5%. The land use is predominantly for pasture and soils are for the most part developed and sandy. The high vulnerability is primarily the convex and rectilinear aspects, where the slopes can reach 15%. On the prevailing pasture, however, the expansion of the sugar cane crop was found and soil exposed to its successive planting. The very high vulnerability is present in the concave slopes, whose curvature favors the convergence of rainwater and thus, linear flow. This event is intensified towards the steep slopes – more than 20% of the region. Combined with these attributes, on shallow soils there is intensive grazing of livestock, which accelerates soil compaction and leads to erosion, one of the most recurrent means of degradation in the Far West of São Paulo. Thus, the present study may contribute to guiding the management of preventive and corrective measures to control erosion through environmental planning.

Construction activity is known to have a major impact on the environment and is a major consumer of a wide range of naturally occurring and synthesized resources. Despite the recognition that environmental issues are important to the survival of the construction industry, the industry continues to degrade the environment, exploiting resources and generating waste, and is slow to change its conventional practices to incorporate environmental matters as part of its decision making process. With increased awareness and knowledge of these impacts, efforts are being made to avoid these adverse effects and to work towards impact mitigation. Among these is sustainable building material selection. Building material selection is an important issue in building design and construction decision-making and environmental issues need to be incorporated into the evaluation process. The research reported in this thesis was initiated to address these issues in the UK, towards developing an assessment model for incorporating sustainability into building material selection process. A questionnaire survey was conducted to investigate the level of awareness, knowledge and implementation of sustainable practices among architects and designers and how this impacts on their design decisions. To facilitate the implementation of sustainable practices into building material selection, a set of sustainable assessment criteria (SAC) for modeling and evaluating sustainability performance of building materials was developed. Building material can be assessed using an index system that combines the principal criteria of sustainable development. The derived criteria were assessed and aggregated into a composite sustainability index using the Analytical Hierarchy Process (AHP) technique which has been praised for its ability to incorporate both objective and subjective considerations in the decision process. The development of a sustainability index is a way of supporting decision makers faced with making numerous and sometimes conflicting evaluation as with building material selection. The methodology adopted in undertaking this research was the mixed method approach involving a detailed review of the relevant literature, followed by an industry-wide survey of UK architects and designers. Following this, case study was conducted to collect data for sustainability criteria used in the assessment model. The data collected were analyzed, with the aid of SPSS, Excel and expert choice software using a variety of statistical methods including descriptive statistics analysis, relative index analysis, Kendall’s concordance and factor analysis. The key finding was the existing gap between awareness and implementation of sustainable construction practices, which has led to failure of realizing the benefits of a sustainable approach to construction. The study showed a discrepancy between what architects and designers claim to be convinced about, and knowledgeable in, and their commitment and practices; they seem to be unable to translate their environmental awareness and knowledge into appropriate design decisions and are in need of a decision support system that can aid the incorporation of sustainability into building design. The model developed satisfy this gap and was validated by application to a roof covering material selection decision process for a case study building project by means of experts’ review via a survey and the findings obtained suggest that the model is valuable and suitable for use in practice. Finally, areas for further research were identified.

Resumo: A bacia do Rio Jundiaí Mirim, compreendida nos municípios de Jundiaí, Jarinu e Campo Limpo Paulista, embora seja considerada, na sua maior parte, como uma área de conservação ambiental, tem sido atingida por pressões antrópicas, incluindo ocupação desordenada, operações mineiras, práticas agrícolas inadequadas, desmatamento, entre outras. Cerca de 97% do abastecimento de água da cidade de Jundiaí, o principal pólo consumidor local, é captado dessa bacia. Apesar dessa situação preocupante do uso da terra na área da bacia, nenhum estudo consistente foi realizado até hoje sobre seu impacto potencial sobre o abastecimento de água na região. Nesse contexto, esta pesquisa teve como principal objetivo traçar uma metodologia de análise do risco a perda da capacidade hídrica da bacia do Rio Jundiaí Mirim em função da impermeabilização do solo ocasionada pela ação antrópica, relacionando características morfométricas da bacia à informações pedológicas e ocupacionais. Dois métodos básicos foram utilizados para integração e análise espacial dos dados: o Processo Analítico Hierárquico (PAR) (método dirigido pelo conhecimento) e a Regressão de Multivariáveis (RM) (método dirigido pelos dados). Mapas de favorabilidade da manutenção da capacidade hídrica da bacia foram gerados através do método PAR, retro-ajustado pelo método RM, para dois cenários: (i) ocupação atual da bacia e, (ü) ocupação máxima para manutenção da capacidade hídrica dos canais principais da bacia. A análise cruzada nem os mapas gerados para esses dois cenários permitiu a derivação do produto-alvo desse estudo: um mapa de classes de risco a perda da capacidade hídrica da bacia. Dez Cinco sub-bacias foram classificadas como de muito baixo e baixo risco a perda de suas capacidades hídricas. Segundo os critérios utilizados na análise e considerando as condições atuais de ocupação, a bacia do rio Jundiaí Mirim não apresenta áreas de alto risco quanto a sua capacidade de fornecer água para as cidades da região
Abstract: The Jundiai Mirim river watershed (JMRW) is comprised within the cities of Jundiaí, Jarinu and Campo Limpo Paulista. Although a large portion of this watershed is considered a site of environmental protection, the area has been increasingly submitted to anthropic-related changes, including intricate house settlement, mining operations, damaging farming practices, deforesting, etc. Some 97% of the city of Jundiaí water supply, the main consuming center in the area, comes :&om the JMRW. Albeit this improper land use within the watershed is widely acknowledged, there have been no comprehensive scientific investigations as regards the potential impacts and threats that such anthropic changes may inflict in the water supply of the region. In this context, the main objective of this project is to develop a method for risk assessment of the potential loss of the JMRW hydric capacity, focusing on the effects of soil impermeability driven by antropic events and considering the synergy between morphometric, pedological and landuse characteristics of the watershed. Two basic methods were employed for data integration and spatial analysis: the Analytical Hierarchy Process (AHP - a knowledge-driven method) and the Multivariables Regression (MR - a data-driven method). Maps of favorability of hydric capacity maintenance were produced through AHP, and the mo deI was retro-adjusted by MR calculations. Two scenarios were considered: (i) present occupation of the watershed; and (ii) maximum possible occupation within a protective limit to maintain the hydric capacity of the main rivers of the watershed. Cross analysis of the favorability maps created for these two scenarios yielded the aimed risk assessment map for the JMRW. Five sub-basins were classified within very low and low risk to loose their hydric capacity. Considering the criteria employed in this work and the existent pattern of landuse, the JMRW shows a situation of overall low risk and it has the necessary resources to keeping the water supply of the region

A maioria dos empreendimentos do setor elétrico brasileiro não apresentam uma avaliação sistemática espaço-temporal de suas estruturas para identificar vulnerabilidades ambientais nos empreendimentos. Assim, este estudo teve como objetivo analisar a susceptibilidade de movimento de massa em linhas de transmissão, na região da Serra da Mantiqueira, sujeitas aos efeitos de chuvas tropicais e operacionalizar uma plataforma dinâmica de análise e alerta nas áreas de maior criticidade. Para este trabalho, foram levantados dados estáticos e dinâmicos na região a partir de fontes de acesso público e privado. A seguir, foram definidos os múltiplos critérios através do processo de análise hierárquica (AHP). Utilizando Sistemas de Informações Geográficas (SIG) e álgebra de mapas, foi possível determinar o mapa de susceptibilidade em cinco classes e operacionalizar a plataforma de monitoramento, análise e alerta a riscos ambientais baseando-se nas áreas identificadas e nos dados dinâmicos meteorológicos e hidrológicos. Como resultado, foi gerado um banco de dados geográfico com abrangência regional (14.000 km²), que envolveu 7 critérios: declividade, distância das linhas de transmissão, densidade de drenagem, uso do solo, tipo do solo, densidade de fraturas e falhas, e precipitação. A distribuição das classes de susceptibilidade encontradas na região de estudo foram: muito baixa (1,5%), baixa (12%), média (34,9%), alta (45,3%) e muito alta (6,2%). Foi possível ainda, identificar diferentes movimentos de massa em áreas próximas à linhas de transmissão, quanto próximas aos outros elementos de risco, como moradias, estradas, bordas de reservatórios e torres de telecomunicações. A plataforma de monitoramento operacionalizada possibilitou o estabelecimento de análises dinâmicas sobre a ocorrência de eventos naturais extremos, através do envio de notificações e acesso WEB com o mapa das áreas afetadas. Assim, este estudo pode se tornar um instrumento de avaliação, acompanhamento e gerenciamento para a gestão pública e agências reguladoras do setor elétrico.
Most of the Brazilian electric sector enterprises do not present a systematic space-time evaluation of their structures to identify environmental vulnerabilities in the projects. Thus, this study aimed to analyze the susceptibility of mass movement in transmission lines, in the Serra da Mantiqueira region, subject to the effects of tropical rains and to operationalize a dynamic platform of analysis and alertness in the most critical areas. For this work, static and dynamic data were collected in the region from public and private sources. Next, the multiple criteria were defined through the hierarchical analysis process (AHP). Using Geographic Information Systems (GIS) and map algebra, it was possible to determine the susceptibility map in five classes and to operationalize the monitoring platform for monitoring, analysis and alert to environmental risks based on identified areas and dynamic meteorological and hydrological data. As a result, a geographic database with a regional coverage (14.000 km²) was generated, involving 7 criteria: slope, distance of transmission lines, drainage density, soil use, soil type, fracture and failure density, and precipitation. The distribution of susceptibility classes found in the study region were very low (1.5%), low (12%), average (34.9%), high (45.3%) and very high (6, 2%). It was also possible to identify different mass movements in areas close to the transmission lines, as well as to other risk elements such as dwellings, roads, reservoir borders and telecommunications towers. The operationalized monitoring platform allowed the establishment of dynamic analyzes on the occurrence of extreme natural events, by sending notifications and WEB access with the map of the affected areas. Thus, this study can become an instrument of evaluation, monitoring and management for the public management and regulatory agencies of the electric sector.

To improve their services and maintain patients’ satisfaction, healthcare organisations have adopted and applied different quality tools and models in recent times, with some even developing their own quality-based initiatives. For example, the approach of Lean Six Sigma (L6σ) has recently been gradually and slowly implemented in healthcare institutions. However, the nature and complexity of healthcare environment which directly impact on humans require leaders to carefully apply appropriate Quality Management (QM) systems suitable for this critical environment. The aim of this research project is to develop a Knowledge Based System (KBS) to assist healthcare managers and practitioners during decision-making process in the context of achieving excellent benchmark and action plans prioritisation. The system will be built based on a conceptual framework for Quality Management in Healthcare Environment (QMHE) which will be modified into a model. The KBS will be developed from this model with the integration of Gauging Absence of Pre-requisite (GAP) method for benchmarking and Analytical Hierarchy Process (AHP) method for prioritisation. The contribution of this research is the use of KBS with GAP and AHP to develop an integrated Knowledge-Based Lean Six Sigma (KB-L6σ) in QMHE. This will accomplish the necessities of investigating quality problems and recommend suitable solutions according to international best practices. It will use a systematic approach that can be applied multiple times, follow defined steps to secure consistency in the approach and integrate different healthcare management levels to maintain strategic decision-making alignment. It consists of 964 KB rules that have been produced via a knowledge acquisition process from the literature and interviewing experts in the field of QM and L6σ in healthcare environment. Feedback from conferences and system testing were used for the verification of the model, whilst validation was carried out through three case studies implementation at three tertiary hospitals in Oman. The analysis of using the KB system in these hospitals has shown clearly that the developed system is a consistent and reliable methodology for assisting decision-makers in designing, planning, and implementing L6σ for QMHE.

[EN] Leachate from waste landfill or treatment plants is a very complex and highly contaminated liquid effluent. In its composition, dissolved organic matter, inorganic salts, heavy metals and other xenobiotic organic compounds, are found, so it can be toxic, carcinogenic and capable of inducing a potential risk to biota and humans. European law does not allow such leachate to leave the premises without being depolluted. There are many procedures that enable debugging, always combining different techniques. Choosing the best method to use in each case is a complex decision, as it depends on many tangible and intangible factors that must be weighted to achieve a balance between technical, cost, and environmental sustainability. A hybrid method for choosing the optimal combination of techniques to apply in each case, by combining a multi-criteria hierarchical analysis based on expert data, obtained by the Delphi method, with an analysis by the method of VIKOR to reach a consensus solution is presented. This thesis will perform a sensitivity analysis on the weights of the criteria involved in the decision and performance values of the alternatives, expressed both in terms of the decision criteria.
[ES] El lixiviado de los vertederos de plantas de residuos es un líquido muy complejo y altamente contaminado. En su composición se puede encontrar materia orgánica disuelta, sales inorgánicas, metales pesados y otros compuestos orgánicos xenobióticos, por lo que pueden ser tóxicos, cancerígenos y capaces de inducir un riesgo potencial en el medio ambiente y los seres humanos. La legislación europea no permite que tales lixiviados salgan de las instalaciones sin ser depurados. Hay muchos procedimientos que permiten la depuración, siempre combinando diferentes técnicas. Elegir el mejor método a utilizar en cada caso es una decisión compleja, ya que depende de muchos factores tangibles e intangibles que deben sopesarse para lograr un equilibrio entre la técnica, el costo y la sostenibilidad ambiental. Se presenta un método híbrido para la elección de la combinación óptima de técnicas de depuración de entre las disponibles, mediante la aplicación de un análisis jerárquico de criterios múltiples AHP sobre la base de datos de expertos, obtenidos por el método Delphi, junto a un análisis de resultados por el método VIKOR, para llegar a una solución de consenso, que pueda ser asumible por la mayoría de los expertos consultados como propia. En esta tesis se realiza un análisis de sensibilidad en los pesos de los criterios de decisión y en los valores de rendimiento de las alternativas, expresados ambos en términos de los criterios de decisión.

En la seua composició es pot trobar matèria orgànica dissolta, sals inorgàniques, metalls pesats i altres compostos orgànics xenobiòtics, per la qual cosa poden ser tòxics, cancerígens i capaços d'induir un risc potencial en el medi ambient i els éssers humans. La legislació europea no permet que aquests lixiviats isquen de les instal·lacions sense ser depurats. Hi ha molts procediments que permeten la depuració, sempre combinant diferents tècniques. Triar el millor mètode a utilitzar en cada cas és una decisió complexa, ja que depèn de molts factors tangibles i intangibles que han de sospesar-se per aconseguir un equilibri entre la tècnica, el cost i la sostenibilitat ambiental. Es presenta un mètode híbrid per a l'elecció de la combinació òptima de tècniques de depuració d'entre les disponibles, mitjançant l'aplicació d'una anàlisi jeràrquica de criteris múltiples AHP sobre la base de dades d'experts, obtinguts pel mètode Delphi, al costat d'una anàlisi de resultats pel mètode VIKOR, per a arribar a una solució de consens, que puga ser assumible per la majoria dels experts consultats com a pròpia. En aquesta tesi es durà a terme una anàlisi de sensibilitat en els pesos dels criteris de decisió i en els valors de rendiment de les alternatives, expressats tots dos en termes dels criteris de decisió.

Our country is a risky position in terms of natural disasters. In the long run, preferentially settlement areas were selected to ensure maximum benefits in terms of both economic and security aspects, other criteria is not taken account when selection of sites. The main purpose of this study is to examine and compare the properties of settlement location based on natural hazard and environmental constraints to be able to understand the interaction between the settlements and natural conditions at the regional scale of YeSilirmak Basin. A MCDA was set up with 10 different data layers in two data domains (environmental and natural hazards domains), are evaluated. The results of the MCDA scores are then transferred to settlement databases in order to evaluate the number of existing settlements in different environmental and natural hazard related suitability classes. It is found that almost 29% of YeSilirmak catchment is environmentally favorable for settlement, and in coherence with that 41% of all existing settlements are located in this zone, indicating a clear preference among the perception of environmentally better places to be settled in. On the other hand with respect to the natural hazards dataset, the locations of the settlements fail to create any preference, as 73,32% of the area is used by 73,50% of existing settlements, which indicates that the perception of natural hazards are low and do not effect settlement criteria, while the acceptable risk of community is high.

Change from a regulated to deregulated structure means that, the centralized maintenance system is not valid any more. In the surveyed published literature, there is not a single model which incorporates all maintenance cost components to analyze the effect of different maintenance strategies for generator companies (GENCOs). The work enclosed in this thesis demonstrates that there is a considerable requirement for accurately modelling cost components of the maintenance model, to be used in maintenance scheduling for deregulated power system, in order to attain a superior schedule with major financial and operational impact. This research investigates and models most cost factors that affect the maintenance activities of the deregulated GENCOs, and demonstrates the utilization of the developed cost models in maintenance scheduling. It also presents the data gathering process for the developed maintenance cost model. A generator maintenance scheduling model that considers direct and indirect maintenance costs, opportunity costs (i.e. loss of customer goodwill), effective maintenance strategies, failures, and interruptions is developed. A Genetic Algorithm (GA) based approach is employed to achieve maintenance schedules to various generators maintenance scenarios. An Analytical Hierarchy Process (AHP) approach is proposed for modelling customer goodwill. The maintenance model was redeveloped under the Reliability Centred Maintenance (RCM) strategy to analyze the effect of a maintenance strategy on maintenance costs. Case studies are presented to demonstrate the utilisation of the developed models.The investigation shows that the market prices, opportunity costs and maintenance strategy have an effect on the final maintenance schedule. The research demonstrates that the cost components are critical factors to achieve an effective maintenance schedule, and they must be considered and carefully modelled in order to reflect more realistic situation for maintenance scheduling of generator units in deregulation environment.

It also presents the data gathering process for the developed maintenance cost model. A generator maintenance scheduling model that considers direct and indirect maintenance costs, opportunity costs (i.e. loss of customer goodwill), effective maintenance strategies, failures, and interruptions is developed. A Genetic Algorithm (GA) based approach is employed to achieve maintenance schedules to various generators maintenance scenarios. An Analytical Hierarchy Process (AHP) approach is proposed for modelling customer goodwill. The maintenance model was redeveloped under the Reliability Centred Maintenance (RCM) strategy to analyze the effect of a maintenance strategy on maintenance costs. Case studies are presented to demonstrate the utilisation of the developed models.The investigation shows that the market prices, opportunity costs and maintenance strategy have an effect on the final maintenance schedule. The research demonstrates that the cost components are critical factors to achieve an effective maintenance schedule, and they must be considered and carefully modelled in order to reflect more realistic situation for maintenance scheduling of generator units in deregulation environment.

The increased demand for biofuels is expected to put additional strain on the available agricultural resources while at the same time causing environmental degradation. Hence, new energy policies need to be formulated and implemented in order to meet global energy needs while reducing the impact of biofuels farming and production. This research focuses on proving a decision support system which can aid the formulation of policies for the sustainable biofuel production. The system seeks to address policy formulation that requires reconciliation of the qualitative aspects of decision making (such as stakeholder’s viewpoints) with quantitative data, which often may be imprecise. To allow this, based on: Fuzzy logic and Multi Criteria Decision Making (MCDM) in the form of Analytical Hierarchy Process (AHP). Using these concepts, three software functionalities, “Options vs. Fuzzy Criteria Matrix”, “Analytical Hierarchy Process” and “Fuzzy AHP” were developed. These were added within the framework of pre-existing base software, Compendium (developed by the Open University, UK). A number of case study based models have been investigated using the software. These models made use of data from the Philippines and India in order to pinpoint suitable land and crop options for these countries. The models based on AHP and Fuzzy AHP were very successful in identifying suitable crop options for India by capturing both the stakeholder viewpoints and quantitative data. The software functionalities are very effective in scenario planning and selection of policies that would be beneficial in achieving a desired future scenario. The models further revealed that the newly developed software correctly identified many of the important issues in a consistent manner.

Forward osmosis (FO) is an emerging technology for water treatment due to their ability to draw freshwater using an osmotic pressure gradient across a semi-permeable membrane. However, the lack of draw agents that could both produce reasonable flux and be separated from the draw solution at a low cost stand in the way of widespread implementation. This study had two objectives: evaluate the performance of three materials — peptone, carboxymethyl cellulose (CMC), and magnetite nanoparticles (Fe3O4 NPs) — as potential draw agents, and to use multi-criteria decision matrices to systematically prioritize known draw agents from literature for research investigation. Peptone showed water flux and reverse solute flux values comparable to other organic draw agents. CMC’s high viscosity made it impractical to use and is not recommended as a draw agent. Fe3O4 NPs showed average low fluxes (e.g., 2.14 LMH) but discrete occurrences of high flux values (e.g., 14 LMH) were observed during FO tests. This result indicates that these nanoparticles have potential as draw agents but further work is needed to optimize the characteristics of the nanoparticle suspension. Separation of the nanoparticles from the product water using coagulation was shown to be theoretically possible if only electrostatic and van der Waals forces are taken into account, not steric repulsion. If coagulation is to be considered for separation, research efforts on development of nanoparticle suspensions as FO draw agents should focus on development of electrostatically stabilized nanoparticles. A combination of Fe3O4 NP and peptone showed a higher flux than Fe3O4 NPs alone, but did not produce additive or synergistic flux. This warrants further research to investigate more combinations of draw agents to achieve higher flux than that obtained by individual draw agents. Potential draw agents were prioritized by conducting a literature review of draw agents, extracting data on evaluation criteria for draw agents developed over the past five years, using these data to rank the draw agents using the Analytical Hierarchy Process (AHP) and Technique for Order of Preference by Similarity to Ideal Solutions (TOPSIS). The evaluation criteria used in the ranking matrices were water flux, reverse solute flux, replenishment cost, regeneration cost, and regeneration efficacy. The results showed that the top five ranked draw agents were P-2SO3-2Na, TPHMP-Na, PEI-600P-Na, NaCl, and NH4-CO2. The impact of the assumption made during the multi-criteria decision analysis process was evaluated through sensitivity analyses altering criterion weighting and including more criteria. This ranking system provided recommendations for future research and development on draw agents by highlighting research gaps.

evaluate disruption risks in the supply chain of petroleum production. This methodology is developed to formalise and facilitate the systematic integration and implementation of various models; such as analytical hierarchy process (AHP) and partial least squares structural equation model (PLS-SEM) and various statistical tests. The methodology is validated with the case of Nigeria’s oil industry. The study revealed the need to provide a responsive approach to managing the influence of geopolitical risk factors affecting supply chain in the petroleum production industry. However, the exploration and production risk, and geopolitical risk were identified as concomitant risk factors that impact performance in Nigeria’s oil industry. The research findings show that behavioural-based mechanisms successfully predict the ability of the petroleum industry to manage supply chain risks. The significant implication for this study is that the current theoretical debate on the supply chain risk management creates the understanding of agency theory as a governing mechanism for supply chain risk in the Nigerian oil industry. The systematic approach results provide an insight and objective information for decisions-making in resolving disruption risk to the petroleum supply chain in Nigeria. Furthermore, this study highlights to stakeholders on how to develop supply chain risk management strategies for mitigating and building resilience in the supply chain in the Nigerian oil industry. The developed systematic method is associated with supply chain risk management and performance measure. The approach facilitates an effective way for the stakeholders to plan according to their risk mitigation strategies. This will consistently help the stakeholders to evaluate supply chain risk and respond to disruptions in supply chain. This capability will allow for efficient management of supply chain and provide the organization with quicker response to customer needs, continuity of supply, lower costs of operations and improve return on investment in the Nigeria oil industry. Therefore, the methodology applied provide a new way for implementing good practice for managing disruption risk in supply chain. Further, the systematic approach provides a simplistic modelling process for disruption risk evaluation for researchers and oil industry professionals. This approach would develop a holistic procedure for monitoring and controlling disruption risk in supply chains practices in Nigeria.

Esta Tesis centra la atención en la aplicación que los SIG pueden tener en diferentes campos de la economía como las empresas minoristas o los centros tecnológicos intensivos en conocimiento. Los SIG pueden definirse como el conjunto de herramientas para recoger, almacenar, transformar y mostrar los datos espaciales para un conjunto particular de propósitos (Burrough, 1988). Por su parte, Barredo (1996) precisa que los SIG son sistemas digitales que, a través de un conjunto de herramientas de hardware y de software, permiten el análisis y manipulación de datos geográficos proporcionando una modelación de la realidad. Por una parte, en el sector minorista, la apertura de un nuevo local es un factor crítico ya que comporta una serie de riesgos monetarios y de imagen muy elevados para la empresa. Por ello, resulta clave realizar un correcto análisis de la localización para las nuevas aperturas (Hernández & Bennison, 2000). El uso de los SIG ha facilitado la comprensión de la información geográfica para los gerentes que carecen de conocimientos técnicos, ayudándoles, por tanto, a tomar decisiones difíciles y de gran envergadura (Ozimec et al., 2010). Además, los SIG son capaces de gestionar la información cartográfica con datos alfanuméricos. Por ello, los SIG se están convirtiendo en una herramienta indispensable para la toma de decisiones sobre la localización de establecimientos (Mendes & Themido, 2004). Por otra parte, los centros tecnológicos, cuando se conciben como proveedores de servicios avanzados para permitir la innovación (COTEC, 2003), también pueden ser considerados ¿minoristas¿ cuyo producto son los servicios intensivos en conocimiento o knowledge intensive business services (KIS). Por lo tanto, el concepto de trade areas también se puede aplicar a los centros tecnológicos en cuanto a su ubicación y el diseño de sus estrategias, entre otros aspectos. Así, diferentes autores destacan la importancia de la proximidad geográfica de los centros de tecnología para que puedan ofrecer un servicio eficaz y apoyar a las empresas (Barrio & García-Quevedo, 2005; Tödtling & Kaufmann, 2001). Por ello, en la investigación que se llevará a cabo en esta Tesis, también se aplicarán técnicas GIS a los centros tecnológicos, en un intento de mejorar el conocimiento sobre los determinantes de la distribución espacial entre las empresas asociadas a un centro tecnológico.

The utilization of Geographic Information System (GIS) offers a wide range of applications for groundwater assessment, delineation, discovery, and resource management. The aim of the present study is to establish a long-term plan for groundwater consumption by implementing novel approaches that ensure the proper utilization and effective maintenance of critical groundwater resources. In this study, GIS techniques, employing Satty's analytical hierarchy method (AHP), were used to demarcate groundwater potential zones in the National Capital Territory (NCT) of India. Seven spatial and non-spatial thematic layers, including Slope, Geology, Rainfall, Soil, Land use / Land cover, Soil, Lineament, and Drainage Density, were examined in the GIS software, and appropriate weights were assigned to define the Groundwater potential zones. An integrated map for Delhi, India was generated as a result. The groundwater potential areas were categorized into five zones: 1-very poor, 2-poor, 3-moderate, 4-good, and 5- very good. The very poor class covered an area of 12.87 km2, poor class covered 174.24 km2, moderate class covered 695.58 km2, good class covered 592.61 km2, and very good class covered 23.08 km2, respectively. This study helps in effective resource management, water supply planning, agricultural development, environmental protection, and disaster management. By understanding the distribution and availability of groundwater, stakeholders can make informed decisions to ensure sustainable use and protection of this valuable resource.

Taiwan Power Company (TPC) is a public service unit in Taiwan; its main business includes generating, transporting and distributing electricity. Field staff of TPC must continually install new or inspect existing power network along roads or in mountainous areas in order to provide adequate services to customers so that they suffer high frequency of transportation-related accidents. During the period between 2001 and 2010, there are 291 traffic accidents, or 62.7% of the total number of accidents for TPC, reported by field staffs causing financial losses to the Company and indelible pains to the surviving family. In this research, a “safety factor” is proposed based on analyzing the information and data collected on the national and TPC transportation-related accidents for recent decades as the basis for evaluating the overall traffic safety. Questionnaires are then distributed to TPC field engineers and personnel who are involved in various levels of TPC management to collect their opinions and comments. The information is then analyzed using the AHP (Analytic Hierarchy process) to find out causes for the reported accidents, and the results reveal that the C.R.iterion order of importance for the traffic safety factor is “human factor”, “Environmental factor”, “road factor”, and “vehicular factor”. Factors such as drunk driving, not obeying traffic signals, obstacles on road, and uneven road surface are identified to cause accidents. Additionally, for TPC field staffs, scattered aggregates and pebbles, puddles, loose sand and aggregates, and uneven road surface caused by sporadic afternoon thunderstorm are recognized to cause high frequency of traffic accidents. Recommendations based on the findings have been proposed to TPC for improving the situation to reduced future accidents.

With the rapidly growing trend of wearable technology, the development of these devices is becoming more important as technology is continuously being integrated into our daily life. International investigation firm Gartner predicted that global output of wearable technology devices will be $ 10 billion by 2016. The application potential in many different industries are limitless and of a time sensitive nature as many firms are already developing and bringing products to market. In the healthcare industry alone, the wearable technology device provides many self-management health platforms including front-end physiological parameter gathering, and back-end expert consultation. In one specific example, they are currently developing a smart phone APP, which accumulates users' physiological parameters from either intelligent wearable technology devices or manual input, and feeds it into an online cloud database, where experts such as a nutritionist can effectively offer timely feedback to the user. The main purpose of this study is to obtain critical factors regarding how new products such as intelligent medical wearable devices should be designed, based on experts’ opinions, in order to improve the customers’ acceptance of this technology, and assist in new product development from start to growth. The initial criteria of this study were based on previous smart phone design references and in-depth interviews with experts who have years of experience understanding adapted use of such medical devices by customers. We then screened the initial criteria with the Fuzzy Delphi method and used the analytical hierarchy process (AHP) method to obtain critical factors with relative importance weights that can provide designers as well as business planners suggestions in the new product development stage. The result showed that the most significant dimension of intelligent wearable device in the health-care field is the "functional properties"; the second is the "style image", while the "environmental concern" has less impact. Further analysis of the factors under dimensions also showed that "the functional convenience properties" is the most important. This suggests that in addition to providing on-time measuring functions through cloud computing technology, the intelligent wearable medical device should also provide other fundamental and useful functions such as vibration warning, etc. Although our study showed that the environmental factor is not significant, we suggest that the recycling technology is worth concerned, as it could eliminate unnecessary waste or even lower related costs of the intelligent medical wearable devices. The recommendation for future research is that we can use the big data we have collected from this platform to classify customer groups, and cross analyze the results of this study with other research areas for future and varying industry analysis.

This is a study base on Analytical Hierarchy Process (AHP) which we discuss with the promotion policy of LPG vehicles and its performing limitations. Then analyzing the main factor with questionnaires in which LPG vehicles could be accepted by the public. The results show that the safety of LPG vehicles is most emphasized which including the safety of LPG equipments and the promotion of its safety. For example, the gas steel cylinders of LPG cars are safer than the fuel tanks of the cars we drive, however, people still think there is a possibility of explosion and afraid of changing a LPG engine. The purposes of this study are as follows: 1. To explore the relationship between the difficulties in promoting LPG and the reason it is rejected by the public in Taiwan. 2. Could the present policy be further improved to increase the will of people in using LPG engines?

Tourism industry is commonly known as non-smokestack industry. The challenges of Taiwan's economy are confronted with wages stagnation as well as the limited and contracted employment opportunities. The tourism industry not only can promote and expand employment, stimulate growth of economy, but also can bring in the multiplier effect serving as a new driver of economic growth in Taiwan. This study focuses on the National Scenic Area (NSA), explores factors of marketing competitive advantage, and constructs effective focused marketing strategies. National Scenic Area is an important resource for Taiwan tourism industry. To build a competitive advantage and a superior positioning in the minds of domestic and overseatourists, tourism industry must transform from the traditional producers and providers into a "value creator", and strive to create a value-added NSA. Regarding of the market segment, target market selection and even the strategic positioning as well as the marketing mix under the strategic planning, 4P must be re-examined and reformed to meet the new era of consumer demand for domestic and foreign tourists. This study uses modified Delphi methodwith Analytic Hierarchy Process (AHP) and targets interviewees from industrial, governmental and academics sectors. The results discover that (a)While constructing competitive advantage for the NSA, “strategic positioning” should be first emphasized, in particular, developing distinct long-term strategic goals; (b) in terms of product strategies, the NSA should focus on integrated product strategies regarding top tourism services quality, transportation convenience, diverse recreational activities and accommodation facilities, i.e. to construct superior products; (c) as for pricing strategies, NSA should tailor its strategic pricing to different targeted groups, and should integrate the development of related supportive industries, design modular tour packages to enrich the versatility of competitive pricing and construct marketing competitive advantage; (d) the NSA should adopt both virtual and actual channel strategies as their channel strategiesand combine themwith related industries to establish integrated channel network enabling a full range of seamless travel experience for tourists and visitors; (e) after strategic positioning and enhancing the product strategies are accomplished, additional integrated marketing components can have massive marketing campaigns ready to be launched.

Open tendering procedure generally plays a major part in public constructions procurement procedures to award the procurement by selecting the most appropriate supplier with either "the lowest-price tender" or "the most advantage tender". Awarding the procurement based on the principle of the lowest-price ender usually execute the inspection of low-price and low-quality. The consequence of this rule of tender-awarding might cause the continuously disturbing of maintenance to the entity, or the controversy of contract performing during the stage of inspection and acceptance. Awarding the procurement based on the principle of the most advantage can solve the problem of low-quality construction caused by the lowest-price tender orientation, however, the formulation of selecting component and selecting weight to synthesize the integral competence of suppliers to ensure them to contract it. This research will adopt the analytic hierarchy process to constitute its selecting element, and proceed with the questionnaire to build the selecting items and weights to assist the government in the reference basis of selecting suppliers for procurement projects.

A credit scoring model integrates a statistical method with the opinions of an expert group and therefore contains a combination of risk factors and weights. The assignment of weights in the modeling processes is a central interest of and a prime challenge for most financial institutions. Traditionally, an expert group determines the weights in accordance with the experts’ views on the importance of the various risk factors. However, the group’s members often have conflicting objectives (i.e., risk minimization vs. market share maximization) and can be dominated by a single dominating opinion maker, which leads to bias and poor model performance. The analytic hierarchy process (AHP) is a multiple-criteria decision-making tool that has been successfully used in various fields. This study is the pioneer to apply the AHP method to the credit scoring process to create a model that increases the predictive power. The study then tests the AHP model in a case study and compares the results with existing scoring techniques. The findings suggest that the AHP scoring model significantly improves the credit scoring model’s predictive ability.

There are technology and knowledge-intensive properties in the medical equipment industry. Its output grows up double in recent years. Output of medical equipment industry in Taiwan in 2004 is NT$50.4 billion and export value is NT$ 27.6 billion. We expected the output of medical equipment in Taiwan to achieve NT $200 billion by 2011. In order to advance the quality of medical services, the Department of Health, Executive Yuan issued "specific medical technology inspects of administration of medical equipment or uses management approach ", but it has not enough relevant regulations of medical equipment in Chinese medicine. The application of Chinese medicine uses a lot of equipments for diagnosis or treatment due to technological development in recent years, but certification of relevant medical equipment has not definite clearly standard of selling and operators’ qualifications. This study focuses on the research of domestic and foreign literatures and government agency system, and questionnaires of domestic dealer and physician. And this study used Analytic Hierarchy Process (AHP) to find a complete set of the operation qualifications of the medical equipments in Chinese medicine. It can make medical and research in Chinese medicine scientific in the future.

This study employs Analytic Hierarchy process (AHP) to examine the indicating factors of occupational injury. In Dragon Steel, many employees and contractors suffer from occupational injuries each year. To solve the problems, it is necessary to find out the key factors related to the occupational injuries to consolidate the industrial safety and prevent the happening of occupational injury. This research intends to provide references to enhance and improve the company’s management to minimize the happening of occupational injury. This research employs AHP to examine the indicating factors of the occupational injuries of the employees and contractors. With the information derived from the statistics of the occupational injuries in the company over the past ten years, the factors were summarized into six basic indicators: hazard recognition, management mechanism, management personnel, educational training, code of practice, and automatic inspection. This research interviewed 5 management experts and 5 site technicians, who were requested to fill out the questionnaire. The results were processed with AHP to find out the correlations between the factors and the priority of the indicating factors in occupational safety and health as the guidelines for enhancing and improving management to minimize injuries and death caused by occupational hazard.

The fact that Taiwan Power Company (TPC) frequently faces high-risk electrical work has led to the company’s large number of occupational accidents and casualties every year. In fact, over 40,000 TPC employees and contractors deal with high voltage and work under extremely risky conditions, such as underground, in a tunnel, or on top of a power line tower on a daily basis. To protect the life and safety of TPC employees and to maintain the sustainability of power business, the issue of occupational accident is especially worth looking into. In accordance, this research applies Analytic Hierarchy Process (AHP) to examine the index factors of TPC-associated occupational accidents and to collect the data of TPC-associated occupational accidents over the past 10 years. Moreover, interviews with personnel at the management level and field engineers are conducted and analyzed through AHP in a hope to find out the primary index factors as well as hidden risk factors that account for occupational accidents of TPC employees. As a result, this research has discovered that both personnel at the management level and field engineers regard “fall from high places” and “electrical safety hazards” as the primary forms of occupational accidents, and they also rank “hazard awareness” as top one index factor for preventing and improving occupational accidents. To avoid occupational accidents resulted from multi-level contracting, that is, contractors generally failing to follow occupational safety regulations due to a lack of awareness or knowledge of occupational safety and public health, TPC contractors should enhance safety training among employees, and the employees should strictly follow the standards of safe operation. With the efforts from both sides, occupational accidents should be less likely to occur.

In recent years, Armed Forces continually implement the streamlining policy to greatly reduce the personnel maintenance budget. The operation process changes in accordance with organization downsizing. There is no more plenty of manpower to deal with the unplanned work. Therefore, the flexible project management method has been gradually frequently applied. In addition, in order to control execution process, avoid impact from risk occurrence, and precisely complete mission, the project risk management has been the necessary part in the standard operation process. The related management field of Air Force aircraft flight is widespread. The effect factors such as environment, human, mechanism, and etc. could cause the risk of mission. Any malfunction management will lead to severe damage of aircraft. The object of project management in this study is the damage aircraft required for major repair. By means of applying project management method to effectively analyze the risk of project management. This study which conducted Analytical Hierarchy Process (AHP) was based on savant interview and questionnaire investigation to select the project management phase of major repair. Besides, by way of collecting the key factors, sorting active personnel by hierarchy, such as ranking, seniority, and experience, to deconstruct the key factors of project management phase, followed by applying Microsoft Excel program for analysis and comparison to effectively control success key factors of project management. The study results show that “accurate determination of failure”, “parts supportability”, and “market sourcing popularity” is the most critical risk factors. The leadership and management class of Air Force should strictly control these factors and propose adequate solution to eliminate or reduce the management risk and make project operate smoothly.

The main goal of this work is to formulate a mathematical model of a decision support system for choosing the most suitable mode of transport to implement within a metropolitan context, considering uncertainty and ambiguity embedded in transportation problems. The model should consider not only economic parameters such as transport costs, production costs, and transport demand but, above all, environmental and social parameters, which define the quality of the transport service. The study applies a hybrid approach based on two different theories: the Analytical Hierarchy Process (AHP) (Saaty, 1980) and the Evidence- or Dempster-Shafer-Theory (DST) (Dempster 1967; 1968; Shafer, 1976). This is the first time that this methodology is used in the field of local public transport. AHP is used to structure the transportation problem and to define the criteria and alternatives. We used the AHP along with the mathematical Theory of Evidence, called also Dempster-Shafer Theory (DST), to evaluate the users' uncertainty in judgments, and to fuse data coming from diverse sources. Finally, we used the Transformable Belief Model (Smets, 1999) to quantify the probability embedded in belief functions. In the first part of this study, we have carried out a survey to investigate the users‟ point of view about the quality of transport, expressed through fifteen criteria, representative of the transport quality. The criteria were chosen according to the set proposed by Prioni and Hensher (2000), to the criteria included in the Transportation Research Board Handbook (1999) and to the European Standard EN13816. In particular, the chosen criteria are: Accessibility; Security; Cleanliness; Number of offered seats; Crowding; Frequency; Travel Time; Punctuality; Regularity of trips; Flexibility; Information; Single ticket(one ticket for all modes of transport, like a transport card); Intermodality; Pollution; Travel fares. In order to obtain more efficient results, we have divided these fifteen criteria into three macro categories. Each categories is composed of five criteria, and that are: Service Criteria, Time Criteria and External Criteria. Within the proposed survey, shared on the web, the users were asked to rank the chosen criteria. To investigate the transport company‟s point of view, we have extrapolated data, about costs and demand for transport, from financial statements. Among the transport companies that work into the metropolitan city of Bari, we have chosen the Ferrovie Appulo Lucane, which uses both Railway and Roadway transport. Starting from the data about costs and demand of transport, we have obtained the Average Cost curves for Railways and Road Transport. In this way, we have calculated the break-even point between the two curves. Due to the complexity of the transport problem, we have used the Analytical Hierarchy Process to decompose the problem in different levels. Because of the decomposition, we have obtained priority vectors, both for the pairwise comparison matrix of criteria and for the knowledge matrix, which we have taken as basic probability assignments (bpa) for application of the Dempster-Shafer Theory (DST). The DST is used to fuse different users‟ opinions, and to fuse users and company points of view, using the Dempster Rule of Combination. Moreover, the DST is used to take into account Uncertainty embedded in human judgment, thanks to the Belief and Plausibility measures, which are respectively the lower and upper bound of likelihood. Finally, in order to obtain the probability measures, we have used the Pigistic Trasnformation by Smets. The results show which alternatives users and transport company consider the best in relation to analyzed criteria.
