Testo completoAbstract (sommario):
Background: Lean production and performance management are very important aspect in the production process because when activities that do not add value to a product are not reduced or eliminated it would amount to waste which would eventually result to unnecessary cost for the organization. Thus it is vital to have the right performance management system in place to control of the organization. Objectives: The purpose of this thesis is to first identify the different types of production wastes evident in the production process of the case companies and how these waste have been reduced or eliminated. As the management of performance in lean production is very important, the second objective of this study is find out how these companies are currently managing performance in lean production in comparison with the performance management systems model Method: This is a multiple-case study with systematic combining approach as the orientation. Interview and documents are the instruments of data collection. Empirical data from each case has been analyzed based on cross and within case analysis. Construct validity, external validity, and reliability are the basis for scientific credibility of this thesis. Conclusions: Not all types of production wastes are evident in all the case companies studied due to one reason or the other. In reducing or eliminating these wastes, they have adopted different lean principles based on their product type. When it comes to managing performance in lean production it is clear that each of the case company adopts almost similar performance management systems although they have adopted different approach. Suggestions for future research: It would be interesting to undergo a similar research in the service sector to see if the findings arrived would be the same or if it will lead to contradictory results. Additionally, since the main focus was on performance in within the studied case companies, it would be interesting to see the outcome of how performance management between these companies and their external suppliers would turn out.

Manure production and nutrient management in pasture-based dairy production systems by Walter Svinurai The effect of dietary treatments on nutrient excretion was determined and an attempt to improving the retention of excreted nitrogen in stored manure using Aloe ferox leaf gel (AFLG) and pine bark was conducted at a pasture-based dairy farm. The animal mass-balance method was used to determine nutrient excretion by cows fed on three dietary treatments, Lolium perrene-based treatment (LP), Lolium multiforium-based treatment (LM) and Lolium perenne- Trifolium repens -based treatment (LTF). In separate experiments, slurry from dairy cows fed LM was amended with AFLG and pine bark at concentrations of 25, 50, 75 and 100 g/l and stored under anaerobic conditions for 16 days. The highest and lowest excretions of N, P and K were observed in LM and LP treatments, respectively. Increasing dietary N improved K and N retention in milk and, consequently increased milk urea nitrogen (MUN) and N excretion (P < 0.05). The concentrations of AFLG affected N and P retention in manure (P < 0.05). The highest retention in total Kjeldahl nitrogen (TKN) of the initial was 42% AFLG at 25g/l inclusion rate. Ammonium nitrogen (AMN) concentration increased significantly due to the interactive effect of AFLG inclusion rate and time. Pine bark powder significantly improved N and P retention in manure at all concentrations. The retention in TKN was higher (P < 0.05) at 25g/l pine bark powder than other concentrations. The interaction effect of inclusion rate and time increased iii AMN (P < 0.05). Dietary treatments significantly affected nutrient excretion, and AFLG and pine bark considerably improved N retention in stored slurry. Findings from the filed trial suggest the need for more attention on managing dietary nutrients in the post-rainy and cool-dry season when growth of pasture influenced choice of dietary treatments that led to high nutrient excretion. Field simulation of the additives to determine their efficacy and environmental hazards was recommended.

Testo completoAbstract (sommario):
This thesis explores the strategy and its management at the University of Oulu in relation to the political and legal guidance. Conflicting interests inside the organization are also examined. In order to combine both internal and external pressure mechanisms on strategic management and performance measurement, the institutional perspective is needed. Neoinstitutional theory with mechanisms of institutional isomorphism provide framework for understanding what pressure mechanisms affect the most on universities as an organization. In strategic management, attention is also paid to how the strategy is implemented and how the strategic performance is monitored in case university.
Thesis is executed as qualitative case study which aims to describe how the external pressure mechanisms for institutional isomorphism a) materialize in the strategic management and b) reflect on the performance measurement criteria of University of Oulu. The analysis was primarily based on three managerial documents. Complementing information was acquired through interviewing the person responsible for these managerial documents, university intranet and official publications. The analysis was carried out as theory-grounded content analysis.
The data was coded in theory-based categories: coercive / regulative, mimetic / cultural-cognitive and normative. As a result of analysis it can be stated that institutional isomorphism is materialized in the case of University of Oulu through all three aforementioned mechanisms. The coercive features are based on University law, MCE funding criteria, MCE performance agreement and other laws or regulations. The mimetic features are related to organization structure, management frameworks, monitoring systems and other things, for example profiling. The normative features are rooted in academic profession, social obligations, recruiting and accreditation. The most visible finding regarding the performance measurement were a) strong influence of coercive mechanism through MCE funding criteria, which shows as almost complete copying of funding criteria to be used as performance measurement indicators in strategic management b) the need to further develop the PM system.
The findings of this study are from many parts in accordance with previous studies utilizing the same framework in university context and are considered reliable. However further conclusions about how the institutional isomorphism influences other universities’ strategic management and performance measurement cannot be drawn based on this case study. Thus more research is needed on how the universities form, implement and monitor their strategies under the effect of different external and internal pressures.

Testo completoAbstract (sommario):
A field lysimeter experiment was conducted on a sandy loam soil during the growing seasons of 1989 and 1990. The experiment tested the effects of four water table treatments on soybean (Glycine max) yields. The water table depths were 40, 60, 80, and 100 cm in depth.Yields were measured in terms of: total seed mass per plant, number of seeds per plant, number of pods per plant, number of seeds per pod, and speed protein content at harvest.
The water management simulation model DRAINMOD, was used to develop irrigation and drainage strategies for soybean production. Three water table management methods were tested with each of three water table depths. The methods were conventional drainage, controlled drainage, and subirrigation, and the water table depths were 40, 60, 80, and 100 cm.
It was shown that for the driest year highest yields are obtained with subsurface irrigation and a weir setting of 40 cm. For the average year, highest yields are obtained with subirrigation and a 60 cm weir setting. For the wet years, best results are found when controlled drainage is used with 80 cm weir setting. It was found that in all but the driest and wettest years controlled drainage improved yields by 10% or more.

Genzyme's manufacturing and supply chain organization is responsible for the production and delivery of medically necessary medicines for patients with rare diseases around the world. Because of the nature of the products produced at Genzyme, a lapse in operational performance has societal as well as economic impacts. Therefore increased understanding of the complex production systems at Genzyme is helpful to reduce risk and improve performance. This thesis is an analysis of a system of two critical production processes at Genzyme. These processes are studied collectively because shared resources make them a tightly coupled system. The research is presented in three sections. The first section explores the current state of the system and explains general performance trends. The second section examines the impact of scheduling complexity arising from shared resources. The third section discusses how process improvement methodologies could be applied at Genzyme. The following conclusions arise from the work conducted for this thesis. First, the performance of the system has declined due to an increase in utilization and an already high level of variability. Second, variability caused by shared resource conflicts can be minimized using new scheduling techniques. And finally, continuous improvement methods are recommended to further reduce variability and increase overall process performance.

Testo completoAbstract (sommario):
This research project introduces a new type of information system, the periodic data production management system, and proposes several innovative system design concepts for this application area. Periodic data production systems are common in the information industry for the production of information. These systems process large quantities of data in order to produce statistical reports in predefined intervals. The workflow of such a system is typically distributed world-wide and consists of several semi-computerized production steps which transform data packages. For example, market research companies apply these systems in order to sell marketing information over specified timelines. production of information. These systems process large quantities of data in order to produce statistical reports in predefined intervals. The workflow of such a system is typically distributed world-wide and consists of several semi-computerized production steps which transform data packages. For example, market research companies apply these systems in order to sell marketing information over specified timelines. There has been identified a lack of concepts for IT-aided management in this area. This thesis clearly defines the complex requirements of periodic data production management systems. It is shown that these systems can be defines as IT-support for planning, monitoring and controlling periodic data production processes. Their significant advantages are that information industry will be enabled to increase production performance, and to ease (and speed up) the identification of the production progress as well as the achievable optimisation potential in order to control rationalisation goals. In addition, this thesis provides solutions for he generic problem how to introduce such a management system on top of an unchangeable periodic data production system. Two promising system designs for periodic data production management are derived, analysed and compared in order to gain knowledge about appropriate concepts and this application area. Production planning systems are the metaphor models used for the so-called closely coupled approach. The metaphor model for the loosely coupled approach is project management. The latter approach is prototyped as an application in the market research industry and used as case study. Evaluation results are real-world experiences which demonstrate the extraordinary efficiency of systems based on the loosely coupled approach. Special is a scenario-based evaluation that accurately demonstrates the many improvements achievable with this approach. Main results are that production planning and process quality can vitally be improved. Finally, among other propositions, it is suggested to concentrate future work on the development of product lines for periodic data production management systems in order to increase their reuse.

La gestion de production s'intéresse à une classe de décisions à prendre dans une entreprise de production de façon à lui faire atteindre son objectif. Comme le problème à résoudre est très vaste, il faut l'aborder au moyen d'une approche hiérarchisée. Les sytèmes de gestion hiérarchiques se caractérisent par plusieurs niveaux de décision coordonnés. Concevoir de tels systèmes suppose de définir les modèles à utiliser à chaque niveau (enntités, objectif, horizon), et une procédure de coordination. Les modèles étudiés dans ce mémoire sont destinés au niveau haut d'un système hiérarchique; l'outil de production est représenté comme un réseau de sous-systèmes à capacités finies et l'objectif à atteindre est la production à flux tendus de familles de produits. On démontre que pour certaines structures de coûts de stockage, il existe un algorithme très simple pour résoudre ce problème d'optimisation déterministe. On montre également qu'il est possible de relaxer cette contrainte et d'utiliser la programmation dynamique, mais le volume de calcul requis s'en trouve considérablement augmentéProduction Management is concerned with a class of decisions to be made in a manufacturing firm in order to gear it towards its objective. Since this decision making problem is very large, it must be approached hierarchically. Hierarchical production management systems are characterized by several decision levels operating in a coordinated fashion. Designing such systems means defining the models to be used at each level (entities, objective, horizon), and a coordination procedure. The models studied in this work are devised for the higher levels of a hierarchy ; the production system is represented as a network of subsystems with limited capacity and the objective sought is to minimize the flow time of product families. It is proved that under certain assumptions concerning the inventory holding costs, a very simple algorithm exists to solve this deterministic optimization problem. It is then shown that it is possible to relax this assumption by using dynamic programming but the amount of computations required increases dramatically

Testo completoAbstract (sommario):
The relationship between volume production and stand density, often termed the 'growth-density relationship', has been studied since the beginnings of forestry and yet no conclusive evidence about a general pattern has been established. Throughout the literature claims and counterclaims concerning the growth-density relationship can be found. Different conclusions have been attributed to the diverse range of definitions of volume and stand density among problems with study design and other pitfalls. Using data from two thinning studies representing non-intensively and intensively managed plantations, one spacing trial, and one thinning experiment a comprehensive analysis was performed to examine the growth-density relationship in loblolly pine. Volume production was defined as either gross or net periodic annual increment of total, pulpwood, or sawtimber volume. These definitions of volume production were then related to seven measures of stand density including the number of stems per hectare, basal area per hectare, two measures relative spacing and three measures of stand density index. A generalized exponential and power type function was used to test the hypothesis that volume production follows either an increasing or unimodal pattern with stand density. These patterns were tested using all combinations of the six definitions of volume production and the seven measures of stand density. Significance of the parameters indicated that different patterns existed depending on the type of management (intensive vs. non-intensive), if thinning is performed, and depending on the definitions of growth and density. The growth-density pattern was generally the same between gross and net production although different patterns emerged when comparing total, pulpwood, and sawtimber volumes. The definitions of stand density which used diameter as a measure of average tree size were more highly correlated with volume production and produced similar patterns while the number of stems per hectare was the least correlated. Further analysis was performed to evaluate Langsaeter's hypothesis which states that volume production is constant and optimal across a wide range of stocking. A mixed-model approach was used to test the equality in mean volume production across a range of planting densities and thinning intensities. To account for the effects of age, the equality in mean volume production was tested separately across a range of ages from 8 to 25 years within the spacing trial data and across a range of one to six years since thinning within the thinning experiment. A multiple comparison test indicate that pattern of volume production and stocking is highly related to the two stages of self-thinning. In young stands, within the distance-independent mortality stage, volume production increases with increasing planting density and therefor increasing stocking. During the distance-dependent mortality stage the assumption of constant and optimal volume production across a wide range of stocking is generally correct. However when mortality began to reduce canopy closure to the point that the residual stand could not recover gaps in the canopy a decline in volume production occurred resulting in a decreasing relationship with increasing stocking. Finally, a system of equations were constructed to describe volume production at the individual tree and stand levels. From this model it was determined that stand level volume production follow an increasing pattern with stand density.Ph. D.

Mestrado em Engenharia e Gestão IndustrialWith the increase of international competition in global markets, a strive for higher quality goods is present in the companies. To sustain and improve market share, companies must produce high quality products in a low-cost perspective and make them available in the market within the shortest time possible. In order to assure that only the best products go to the market, prototypes must be built and tested, iterations and corrections must be made. However, the ability to create feasible prototypes requires a non-standard manufacturing value stream, in order to embrace open creativity, using processes without a focus on the production optimization, but capable of achieving a wide range of product transformations, where each operation might be unique. This thesis presents a proposal of a new Lean Prototype Production Management framework, which outlines results in a manufacturing company, providing better understanding on how Lean Thinking application impacts prototype production management.
Com o aumento da concorrência nos mercados globais, um aumento na necessidade de criar produtos de maior qualidade está presente nas empresas. Para manter e melhorar a quota de mercado, as empresas devem produzir produtos de alta qualidade a baixo custo e torná-los disponíveis no mercado dentro do menor tempo possível. A fim de assegurar que apenas os melhores produtos estão presentes no mercado, protótipos devem ser construídos e testados, iterações e correções devem ser feitas. No entanto, o processo de criação de protótipos viáveis requer um fluxo de valor de produção não-padrão, de modo a abraçar a criatividade aberta, usando processos produtivos com um foco não na otimização da produção, mas capazes de alcançar uma vasta gama de transformações no produto, onde cada operação pode ser única. Esta tese apresenta uma proposta de modelo de Lean Prototype Production Management, que descreve os resultados numa organização industrial, fornecendo uma melhor compreensão de como a aplicação dos conceitos de Lean Thinking tem impacto no processo de gestão de produção de protótipos.

Ndjebayi, Joseph Nloga. "Aluminum Production Costs: A Comparative Case Study of Production Strategy". ScholarWorks, 2017. https://scholarworks.waldenu.edu/dissertations/4468.
Testo completoAbstract (sommario):
Slumping world aluminum prices have energized some aluminum producers to institute strategies to reduce product costs. This multiple comparative case study explored the strategies used by 4 aluminum producers in Western Europe: 2 companies that have successfully reduced production costs and 2 companies that have not. Wicksteed's economic theory of production and production costs was the conceptual framework for this research. Data from the companies' strategic and industry reports and from interviews with 32 senior managers were analyzed using pattern finding and clustering, a recursive approach to data gathering and analysis established by Miles, Huberman, and Saldana. Six themes emerged: (a) upstream integration, (b) energy and price efficiency, (c) carbon-manufacturing capability, (d) operational excellence and productivity, (e) technological and research developmental abilities, and (f) circular economy. The analysis of these themes indicated that the most significant opportunities for productivity improvement include (a) minimizing energy and material use, specifically alumina, cathodes, and carbon, (b) vertically integrating alumina production, (c) developing an efficient circular economic model that integrates the material properties to expand the recyclability of waste, and (d) increasing the electrolytic cell life cycle. Overall, vertical integration provides a competitive advantage and gives the producer ability to control costs. In-house carbon manufacturing capacity reduces a smelter's operating cost. Technological capabilities can minimize energy and material consumption rates. Increased productivity and reduced energy and material use can yield positive social changes, such as the preservation of natural resources, reduced emissions, and waste.

This paper evaluates the logistics for production chemicals used on the offshore installations of the coast of Norway. Statoil provided the following problem description: There are an increasing number of fields on the Norwegian continental shelf that are going in to mature stage of its production. In this part of the field’s life cycle the need for production chemicals are increasing. The problem for the supply chain is that the tank capacity on-board the installations are limited and the procurement process is significant. The technology on the tanks on-board is old and manual readings of the tank level are needed. This could lead to the need for priority calls by the supply vessels, which are costly, or in the worst case stop in production. In the first part of the paper the offshore supply chain at Statoil is described, and a description of the importance of the production chemicals is given. A brief description of the theory related to the problem within the subject of Supply Chain Management is provided, and a chapter describing the field work at Statoil is also given. It was concluded that simulation modelling was to be used in the analysis part of the work. Discreet event simulation is a common method for analysing complex systems. This method allows the user to evaluate effect of changes on a system prior to making them. This is useful since introducing changes in the existing system could be very costly. The simulation case looks at the situation on three of Statoil’s installation on the Norwegian continental shelf. The values that are evaluated is the tank levels for the different chemicals, and how these values develop over time as changes are introduced to the case in different scenarios. There were developed four different scenarios: Scenario one: The systems were modelled with the existing tank capacities with four different demand settings. If no problems were found in this scenario it was assumed that the system functioned satisfactory: AS-IS demand based on the average demand over the last three years 10% increase in this average demand 25% increase of this average demand 50% increase of this average demand Scenario two: Introducing increased capacity. This scenario was evaluated for the cases that had an inadequate result during the first scenario. In this scenario the tank capacities were increased to be able to last for 10 days with a demand given as the maximum possible in today’s situation. The simulation was conducted for the same demands as in scenario one. Scenario three: This report is also evaluating the effect of Integrated Operations, and one important topic in this field is sharing of real time data. Based on this the model was alternated so that the tank levels could be monitored in real time, automatic tank level reading, providing an "IO" improvement to the system. A simulation run with this setup was done for all the installations for the same demand values as in scenario one, and the tank utilization grade was compared to the case in scenario one. Scenario four: In this scenario the automatic tank reading setup was combined with the increased capacity of scenario two. This is assumed to be the most realistic of the improvements, as installation of new and larger tanks offshore most likely would feature this new technology as well. This simulation study can be seen as a "what-if" analysis. And the results are presented below: Scenario one: Satisfactory results for both installation A and B for all the demand levels, indicating a sufficient tank capacity at the given demand. Unsatisfactory results were found for the chemicals H2S remover and Nitrates at installation C Scenario two: Increasing the tanks at installation C for the chemicals mentioned above gave a very large improvement in the result, indicating that the capacity in the existing setup is insufficient for the demand situation. The result was also that there were no problems when the demand rose from the initial average to the 50% increased level. Scenario Three: Allowing for continuous monitoring of the tank levels gave an improved utilization of the tanks at all the installations. The benefits of this alternation to the system was found to be largest in the situations that had the worst results in the original setup used in scenario one. Scenario four: This scenario gave a perfect result for all the demand values that was tested on the case of H2S remover and Nitrates for Installation C. The good results from the alterations in scenario two and three continued to improve when they were combined. Using simulation as a method for analysing the offshore supply chain provides a good overview of the situation and the possible problems. The two possible improvements, increasing the capacity and implementing automatic tank readings both gave good results. Since the possibility to do this evaluation on the real system would not be possible due to the fact that the cost of such alteration would be too large, it was found that simulation provides a good alternative to evaluating the supply chain. The simulation model does not give a recommended or optimal improvement for the cases where problems were discovered, but could be used to evaluate how the system would perform under different circumstances. As stated in the conclusion, no cost calculations have been conducted on the results from the simulation. The result of such an analysis could be that some, or all, the improvements used in scenario two-four are unfeasible. This would have to be evaluated before a recommended solution could be provided.

The effect of level and timing of nitrogen (N) fertilizer application on grain yield (YLD), grain protein (GPC), and breadmaking ability of four hard red spring wheat cultivars and on soil residual nitrate was investigated. Nitrogen fertility caused an increase in YLD, lodging, several yield components, GPC, and breadmaking quality and caused a reduction in N harvest index and grain ash, and N use efficiency (NUE) resulting in an increase in soil residual NO$ sb3$-N. Split N application reduced lodging, tillers and spikes m$ sp{-2}$ and caused an increase in grain weight, GPC, loaf volume and NUE. Grain yield increases were largely due to increases in the grain spike$ sp{-1}$ and tillers n$ sp{-2}$. Absolute protein content was found to be critical in determining GPC. Cultivars showed plastic responses to N. Despite its high YLD and flour yield, Hege 155-85 may be risky to produce because of its high dependence on N. Mineralization of N occurred during winter. Marked differences existed between the sites.

Testo completoAbstract (sommario):
The use of microalgae culture to convert CO2 from power plant flue gases into
biomass that are readily converted into biofuels offers a new frame of
opportunities to enhance, compliment or replace fossil-fuel-use. Apart from
being renewable, microalgae also have the capacity to utilise materials from a
variety of wastewater and the ability to yield both liquid and gaseous biofuels.
However, the processes of cultivation, incorporation of a production system for
power plant waste flue gas use, algae harvesting, and oil extraction from the
biomass have many challenges. Using SimaPro software, Life cycle
Assessment (LCA) of the challenges limiting the microalgae (Chlorella vulgaris)
biofuel production process was performed to study algae-based pathway for
producing biofuels. Attention was paid to material use, energy consumed and
the environmental burdens associated with the production processes. The goal
was to determine the weak spots within the production system and identify
changes in particular data-set that can lead to and lower material use, energy
consumption and lower environmental impacts than the baseline microalgae
biofuel production system. The analysis considered a hypothetical
transesterification and Anaerobic Digestion (AD) transformation of algae-to-
biofuel process. Life cycle Inventory (LCI) characterisation results of the
baseline biodiesel (BD) transesterification scenario indicates that heating to get
the biomass to 90% DWB accounts for 64% of the total input energy, while
electrical energy and fertilizer obligations represents 19% and 16% respectively.
Also, Life Cycle Impact Assessment (LCIA) results of the baseline BD
production scenario show high proportional contribution of electricity and heat
energy obligations for most impact categories considered relative to other
resources. This is attributed to the concentration/drying requirement of algae
biomass in order to ease downstream processes of lipid extraction and
subsequent transesterification of extracted lipids into BD. Thus, four prospective
alternative production scenarios were successfully characterised to evaluate the
extent of their impact scenarios on the production system with regards to
lowering material use, lower energy consumption and lower environmental
burdens than the standard algae biofuel production system. A 55.3% reduction
in mineral use obligation was evaluated as the most significant impact reduction
due to the integration of 100% recycling of production harvest water for the AD
production system. Recycling also saw water demand reduced from 3726 kg
(freshwater).kgBD-
1
to 591kg (freshwater).kgBD-
1
after accounting for
evaporative losses/biomass drying for the BD transesterification production
process. Also, the use of wastewater/sea water as alternative growth media for
the BD production system, indicated potential savings of: 4.2 MJ (11.8%) in
electricity/heat obligation, 10.7% reductions for climate change impact, and 87%
offset in mineral use requirement relative to the baseline production system.
Likewise, LCIA characterisation comparison results comparing the baseline
production scenarios with that of a set-up with co-product economic allocation
consideration show very interesting outcomes. Indicating -12 MJ surplus (-33%)
reductions for fossil fuels resource use impact category, 52.7% impact
reductions for mineral use impact and 56.6% reductions for land use impact
categories relative to the baseline BD production process model. These results
show the importance of allocation consideration to LCA as a decision support
tool. Overall, process improvements that are needed to optimise economic
viability also improve the life cycle environmental impacts or sustainability of the
production systems. Results obtained have been observed to agree reasonably
with Monte Carlo sensitivity analysis, with the production scenario proposing the
exploitation of wastewater/sea water to culture algae biomass offering the best
result outcome. This study may have implications for additional resources such
as production facility and its construction process, feedstock processing
logistics and transport infrastructure which are excluded. Future LCA study will
require extensive consideration of these additional resources such as: facility
size and its construction, better engineering data for water transfer, combined
heat and power plant efficiency estimates and the fate of long-term emissions
such as organic nitrogen in the AD digestate. Conclusions were drawn and
suggestions proffered for further study.

A new inventory management strategy was developed for Schlumberger to reduce waste in material handling and improve the warehouse receiving efficiency. The current warehouse receiving situation was analyzed; then the receiving procedure was summarized and the time spent for each step was measured. After that, the cause and effect analysis for the low efficient warehouse operation was analyzed and solutions are proposed. The implementation of this model in the company has seen significant improvements in warehouse operation efficiency. The receiving time of specific machined parts has been reduced by 32% and the receiving of specific sub assembled parts has been reduced by 53%. The improvement has led to a cost saving of US$ 422,148.

Durch ihre Umwelt- und Nährwertvorteile erweckten Afrikanische indigene Blattgemüse – „African Indigenous Vegetables“ (AIV) in letzter Zeit Aufmerksamkeit als „Supergemüse“ (Cernansky 2015). Da mehrere Spezies aus unterschiedlichen botanischen Familien innerhalb der AIVs vertreten sind, ist ein besseres Verständnis Spezies spezifischer Eigenschaften, wie z.B. Ernährungswert und agronomischem Management nötig, um diese Vorteile voll ausschöpfen zu können. In dieser Arbeit haben wir Afrikanisch indigene Blattgemüsearten aus fünf Familien, inklusive C3 and C4 Spezies und Leguminosen und nicht-Leguminosen (Brassica carinata/Cruciferae - Ethiopian Kale, Amaranthus cruentus/Amaranthaceae - Amaranth, Vigna unguiculata/Leguminosae - Cowpea, Solanum scabrum/Solanaceae - African Nightshade, Cleome gynandra/Capparaceae - Spiderplant) mit einer importierten und in Kenia häufig angebauten Gemüseart (Brassica oleracea acephala/Cruciferae - Exotic Kale) verglichen. Wir betrachteten die Pflanzenarten hinsichtlich ihrer Konzentrationen an wertgebenden und toxischen Elementen in Blättern als Index für den Nährwert, ihrer Reaktionen auf unterschiedliche zur Verfügung gestellten Mengen und Formen an Phosphor (P) als Index für die Adaptation an suboptimale chemische Bodenbedingungen und ihre erntebedingten Nährstoffausfuhren aus dem Boden als Index für den Düngerbedarf. Die Arbeit war in das interdisziplinäre Forschungsprogramm HORTINLEA (Horticultural Innovation and Learning for Improved Nutrition and Livelihood in East Africa) eingebunden.African Indigenous Vegetables (AIVs) have recently captured considerable attention as “super vegetables” due to their nutritional and environmental benefits (Cernansky 2015). As AIVs include many species belonging to different botanical families, more species-specific knowledge e.g. on nutritional value and agronomic management is needed to fully exploit those benefits. In this thesis we compared leafy AIV species from five families including C3 and C4 species, and a legume and non-legume species (Brassica carinata/Cruciferae - Ethiopian kale, Amaranthus cruentus/Amaranthaceae - amaranth, Vigna unguiculata/Leguminosae cowpea, Solanum scabrum/Solanaceae - African nightshade, Cleome gynandra/Capparaceae - spider plant) with a non-indigenous species, which is commonly grown in Kenya (Brassica oleracea acephala/Cruciferae - “exotic kale”). We compared the leaf concentrations of beneficial nutrients and heavy metals as an index for the nutritional value, the performance under different rates and forms of phosphorus (P) supply as an index for adaptation to suboptimal chemical soil conditions, and the harvest-related nutrient outflow from soil as an index for fertilizer need. The thesis was embedded in the interdisciplinary research program HORTINLEA (Horticultural Innovation and Learning for Improved Nutrition and Livelihood in East Africa).

Shi, Wei. "Management of Microbial Nitrate Production in Agricultural Soils". DigitalCommons@USU, 1998. https://digitalcommons.usu.edu/etd/3956.
Testo completoAbstract (sommario):
Nitrate (NO3-) is of central importance in the internal soil nitrogen (N) cycle. While animal wastes and nitrification inhibitors have been used in modern agriculture for decades, their effects on soil NO3- production in relation to ammonium (NH4+) availability and nitrifier population activity in agricultural soils receiving animal wastes or nitrification inhibitors.
Several laboratory and field studies assessed the impacts of variously treated dairy wastes and the effects of repeated long-term use of a nitrification inhibitor, nitrapyrin, on microbial NO3- production and soil NO3- concentrations in Utah agricultural soils. The various process rates of N mineralization, nitrification, and microbial N immobilization were determined in laboratory and field systems using 15N isotope dilution techniques. Nitrification potentials were used simultaneously to measure the nitrifier population size and activity.
Microbial NO3- immobilization was not observed in the laboratory and field experiments. The lack of microbial NO3- immobilization was not observed in the laboratory and field experiments. The lack of microbial NO3- consumption indicates that nitrification was the primary process controlling soil NO3- concentrations. Nitrifiers were not weaker competitors than heterotrophs for utilizing soil NH4+; about 50% of the NH4+ mineralized was used by nitrifiers. Low carbon availability may have limited heterotrophic microbial growth, thereby minimizing the heterotrophic microbial consumption of NH4+ and NO3-.
Effects of dairy wastes on soil NH4+ availability depend on the treatment systems of dairy wastes and their application rates. The N mineralization potentials were approximately 5% of the organic N in dairy-waste compost versus 90% of the organic N in dairy waste digested anaerobically. Dairy-waste compost at appropriate application rates did not increase nitrification rates, nitrification potentials, or soil NO3- concentrations for several months following application. However, even stabilized dairy-waste compost led to high nitrification rates and potentials and elevated soil NO3- concentrations when it was applied at an excessive rate (i.e., 100 Mg dry wt. ha-1).
In a dryland wheat agroecosystem, repeated use of nitrapyrin for 8 years had a 2-year residual effect observed as lower nitrification potentials in soils with a history of nitrapyrin use compared to soils without that history.

Testo completoAbstract (sommario):
This thesis covers an introduction to the present conditions for newspaper publishing, definitions and analyses of the processes of newspaper production and distribution, expected future developments with respect to products and production processes, and finally, conclusions regarding the need for global coordination of products, production and distribution.
Primarily, the conditions in the Nordic countries have been analysed. Particular attention has been drawn to Swedish morning newspapers with a circulation exceeding about 50 000 copies per publishing day.
The study has been carried out mainly through literature research, through case studies using the SDA-method, and through acquisition and analyses of production data from the case studies. In addition, interviews and questionnaires have been used.
A modern newspaper printing plant requires heavy investments. The number of newspaper printing plants is decreasing, but he number of newspaper titles printed in each plant increases. The flexibility in and utilisation of the remaining plants increases as well as the complexity and variety of the products handled.
In all case studies of newspaper production, the companies use fixed production and distribution plans, following the same timetable from day to day. Delayed press starts, deviations from the calculated production speed, and interruptions during the production immediately cause disturbances in the distribution, delay costs, and goodwill losses.
The time needed to produce a fixed number of copies varies within a wide range. Days of more complex production in the production plants meet with problems more often. The average net production speed is progressively reduced at higher page counts. Inserting operations result in an accelerated reduction. The difference is mainly caused by product related differences in cruising speed and by the occurrence of unplanned stops. The coordination of products, production and distribution is essential already today, and will be even more important in the future.
More flexible production and distribution plans would imply controlled and predictable risks. In addition, it will render increased utilisation of the resources available. A product model can be used in order to identify an associated production process model as a set of separate activities. Detailed modelling of the different activities demands detailed tracking and systematic use of the production history. A detailed activity modelling will make it possible to predict the capability of a certain activity in terms of production speed and reliability. This will facilitate coordination on a global level.

Testo completoAbstract (sommario):
Thesis (MScEng)--University of Stellenbosch, 2003.ENGLISH ABSTRACT: Two fundamental aspects in modem business success are performance management and physical asset management. The current problem in the asset management environment is the lack of structured performance management, which is required to effectively control and enhance the dynamics of the asset and its life cycle. The result is ineffective assets with high life cycle costs, which will consequently influence the bottom line and return on investment, negatively. An Asset _eerformance Management Model (APM2 , pronounced A-P-M square) was developed. A sound theoretical foundation together with the experience of a leading asset management consultant resulted in the realization of a model that (i) gives a balanced view of asset performance, (ii) link asset performance to strategic business objectives, (iii) facilitates decision-making and problem solving, and (iv) enhances asset control and continuous improvement. The APM2 was developed by rese~ching and integrating five building blocks, which encompass the model requirements. The APM2 consists of two distinct components, namely: • the APM Reference Structure (APMRS), and • a range of APM Dockets. The APMRS is a basic structure that integrates the various building blocks into a framework for providing guidance and control, giving perspective on the entire model and explaining the high-level content of the model. It consists of five levels, each with a distinct focus: • Levell: Enterprise • Level2: Factory • Level3: Process Unit • Level4: Aggregate • Level5: Component The APM Dockets are a subset of the APMRS, where each level has a docket. These dockets are executable, unit-specific procedures, guiding and leading stakeholders towards improved asset performance. Also each of the five levels consists of six similar and inter-related elements. These elements are the foundation for each docket: lement 1: Stakeholders Element 2: Objectives Element 3: Measures Element 4: External Monitor & Targets Element 5: Responsibilities & Decision-Making Element 6: Control & Continuous Improvement Element 7 represents the link to the next level in the APM Reference Structure. • • • • • • Conclusively the APM2,s simplicity and understandability is realized through the APM Reference Structure, while the range of APM Dockets contribute to the practicality objective. The model has a strong theoretical foundation, but at the same time is generic, to be used in a wide range of industries. A leading asset management consultant plans to integrate the APM2 into their asset management program based on the thesis documentation. This application will test and validate the APM2 in practice. It is further recommended that an asset management program, with the associated APM2 , be used in conjunction with the Theory of Constraints and Total Productive Maintenance, because of obvious relationships. Further research is also suggested in relation with some of the experimental asset life cycle phases as well as certain financial considerations.
AFRIKAANSE OPSOMMING: Twee fundamentele aspekte in hedendaagse besigheidsukses is prestasiebestuur and fisiese batebestuur. Die huidige probleem binne die batebestuursomgewing is die gebrek aan gestruktureerde prestasiebestuur, wat 'n vereiste is vir effektiewe beheer en verbeterings rondom die bate en sy lewensiklus. Die resultaat is oneffektiewe bates met hoë lewensikluskoste wat gevolglik wins en beleggingsopbrengs negatief beïnvloed. 'n Prestasiebestuur Model vir Bates (APM2, uitgespreek as A-P-M square) is ontwikkel. 'n Deeglike teoretiese fondasie tesame metdie ondervinding van vooraanstaande raadgewende batebestuurders, het die realisering van 'n model tot gevolg gehad, wat (i) bateprestasie gebalanseerd voorstel, (ii) bateprestasie met strategiese doelstellings verbind, (iii) besluitneming and probleemoplossing fasiliteer, en (iv) batekontrole en voortdurende verbetering bevorder. Die APM2 is ontwikkel deur middel van die identifisering en integrasie van vyf boustene wat die vereistes vir die modelomvat. Die APM2 bestaan onderskeidelik uit twee komponente, naamlik: • die APM Verwysingstruktuur (APMRS), en • 'n reeks APM Vouers. Die APMRS is 'n basiese struktuur wat die verskillende boustene binne 'n raamwerk integreer en sodoende leiding en beheer fasiliteer, die model as geheel in perspektief stel en die modelinhoud op hoë vlak verduidelik. Dit bestaan uit vyf vlakke, elk met 'n spesifieke fokus: • Vlak 1: Onderneming • Vlak2: Fabriek • Vlak 3: Proseseenheid • Vlak 4: Aggregaat • Vlak 5: Komponent Die APM Vouers is 'n subdeel van die APMRS, waar elke vlak 'n vouer het. Hierdie vouers is uitvoerbare, eenheid-spesifieke prosedures wat deelhebbers lei na beter bateprestasie. Ook bestaan elkeen van die vyf vlakke uit ses soortgelyke en inter-afhanklike elemente. Hierdie elemente is die fondasie vir elk van die vouers: • Element 1: Deelhebbers • Element 2: Doelwitte • Element 3: Metings • Element 4: Eksterne Monitering & Mikpunte • Element 5: Verantwoordelikhede & Besluitneming • Element 6: Kontrole & Voortdurende Verbetering • Element 7 stel die verbinding met die volgende vlak in die APM Verwysingstruktuur voor. Gevolglik word die eenvoud en verstaanbaarheid van die APM2 gerealiseer deur die APM Verwysingstruktuur, terwyl die reeks APM Vouers bydra tot die praktiese doelwit. Die model het 'n sterk teoretiese grondslag, maar terselfdertyd is dit generies, sodat dit in 'n wye spektrum van industrieë gebruik kan word. Gebaseer op die tesis dokumentasie beplan vooraanstaande raadgewende batebestuurders om die APM2 te integreer met hul batsbestuursprogram. Hierdie toepassing sal sodoende die APM2 in die praktyk toets en bekragtig. Dit word verder aanbeveel dat 'n batebestuursprogram, met die geassosieerde APM2, tesame met die Theory of Constraints en Total Productive Maintenance gebruik word, as gevolg van voor die hand liggende verwantskappe. Verdere navorsing word ook voorgestel in verband met die eksperimentele fases binne die batelewensiklus, asook rakende sekere finansiële oorwegings.

Bibliography: pages 89-92.The scheduling of production in job shops is generally accomplished in four stages; aggregate planning, machine loading, sequencing and detailed scheduling. In industrial job shops, the number of jobs and machines makes detailed scheduling a particularly complicated and unwieldy task. When faced with this situation, a typical response of managements is to simply ignore the problem and apply some remedial action by adapting existing company operation procedures. The first objective of this dissertation is to indicate the dangers and inefficiencies which result when the problem of detailed scheduling is ignored. This is done in terms of a case study analysis in which the problems which currently exist in the machine shop at Atlantis Aluminium, a jobbing foundry, are illustrated. The second objective is to develop a systematic approach for the solution of detailed scheduling in job shops. Major steps in this approach are: i) a classification of shop scheduling problems ii) a survey of relevant scheduling literature in order to determine existing detailed scheduling techniques iii) the design of the scheduling system This approach is illustrated by applying it to the machine shop at Atlantis Aluminium.

Lean manufacturing has seen its creators, Toyota, rise from insignificance in the middle of the previous century, to the biggest selling car manufacturer in the world today. Another Japanese car manufacturer, Honda, which has also been practising the principles of lean avidly during the last few decades, has also made huge strides towards becoming a dominant force in the car market. These Japanese companies‟ adoption of lean has seen many of their mass producing United States (US) and European counterparts struggle for survival. Maynard (2003:10) predicted that by the end of the decade, at least one of the „Big Three‟ auto makers in the US – Chrysler, Ford, and General Motors (GM) – would be forced to undertake significant restructuring to continue in operation. At the time of this writing all indications are that this prediction will come true. GM is in the process of major shareholding restructuring in an attempt to keep the company afloat, having run up insurmountable debts in the face of the current global economic downturn. Adopting the lean methodology has become a matter of necessity. The continued use of mass production methods alone is no longer viable; companies need to also employ lean methods intelligently in order to remain competitive. This study is regarded as a crucial endeavour to assist operations managers of manufacturing concerns in developing lean implementation strategies which will maximise the benefits to the organization.

Testo completoAbstract (sommario):
The responsiveness of organizational leaders regarding suggestions related to various managerial techniques has led to the coinage of the ‘management fashion’ idiom. It has been convincingly argued that phenomena like management control systems are prone to trends, and that such trends permeate into the daily life of managers through the use of persuasive rhetoric. This thesis is a theory-generating study of change in management control systems. More precisely, its purpose is to seek an understanding of how fashions within the field of management control emerge through processes of interaction and co-production. By asking the question “how do the forces involved in the shaping of a market for management control systems interact and combine in order to create management fashions?” the thesis seeks to generate a comprehensive conjecture on the management fashion setting process. The thesis is based on an empirical case study completed with extensive literature readings. In order to generate theory, a methodology based on abductive reasoning has been produced. Theoretically, the thesis borrows from micro sociological theory on imitation and co-production but extends also into such fields as psychology, aesthetics, rhetoric and economics; aside from the obvious management control and management accounting themes. The thesis concludes by producing a comprehensive model of the management fashion setting process. The contribution of the thesis can be understood as either providing an alternative to or completing the dominant interpretation of the phenomena. The main difference between the arrived at suggestion and the prevailing interpretation is the role of the actors which is changed from norm following consumers of fashion to creative producers of fashion. This change represents a change in scientific traditions and necessitates the adoption of additional frames of reference when studying management fashion phenomena.

Potential applications of the game lie in experimentation, policy formulation and education in mine economics. The Mine Manager is described using the terminology of games.The selection of parameters and of the level of detail in the model reflects a compromise between realism and simplicity. At the development stage, the selection of project specifications concerns the mining method and capacity installation. Decisions on cut-off grade and/or cut-off value, capacity utilization, the sequence of mining, stockpiling and expansion are made during the mine life. Decision making takes place within a framework provided by an abstraction of the operating environment of a mine, and must comply with a set of rules. These rules ensure that only feasible decisions are made. Within this constraint, the model offers a high degree of flexibility in setting the values of the decision variables.
The Mine Manager combines elements of geology, mining, management and gaming. Conditional simulation is used to generate grades of copper, zinc and gold in a massive sulphide deposit. Mining operations in both underground and open-pit mines are modelled, and hypothetical capital and operating cost functions are developed for the mine and mill. A pricing model generates new price series for each run of the game.
The Mine Manager is operated interactively on a microcomputer through the use of modular software. The user interface and a sample run of the game are described, and the information displays created by the game are presented.
