This master’s thesis deals with manufacturing and logistic issues of low voltage cabinets produced by ProCS, s.r.o. company. The aim is to design and evaluate manufacturing and assembling process rationalization proposal. The proposal is based on familiarization with technological process of cabinet's manufacturing. Becoming familiar with manufacturing and assembling process of marshalling and system cabinets made it possible to find an opportunity of rationalization through automation of selected assembling processes. Automation of striping and crimping process is possible through suitable crimping machine. Situation before and after rationalization is economically interpreted and evaluated using break even point analysis. Through mentioned rationalization arrangement it is possible to improve manufacturing flexibility, reduce lead times and cut down manufacturing costs.

The master thesis focuses on the creation of the business plan proposal. Via implemented analysis (SLEPT, SWOT and Porter’s model) and questionnaire research were identified conditions for successful establishment and running of fitness centre M-Gym, s.r.o. in Brno. It involves the choice of tools and strategies, which allows the company to succeed on the market and become competitive.

Denna studie undersöker tidsvinsterna med en investeringen av automatiserade regressionstester i förhållande till manuellt genomförande. Syftet med detta är att skapa ett beslutsunderlag av ROI och break-even beräkningar med avsikten att minska osäkerheten ifall investeringen kommer resultera i en tidsvinst under systemets livslängd samt hur stora dessa vinster kan bli. För att undersöka detta har automatiska regressionstester utvecklats, där en mätning av tidsåtgången för detta användes som den investerade tiden. De automatiska testernas tid för genomförandet av studiens testfall jämfördes med den manuella motsvarigheten. Detta har tillsammans med empiriskt material från intervjuer stått som grund för ROI och break-even beräkningar gällande investeringen av automatiska regressionstester. Det empiriska materialet bidrog till beräkningarna med parametrarna testfrekvens, testmängd och livslängd. Till skillnad från tidigare forskning genomför studien beräkningar med flera testfrekvenser, vilket resulterade i att även vid en relativt låg testfrekvens har automatiska regressionstester goda förutsättningar för ett positivt ROI. Vid en medel till hög testfrekvens kunde break-even punkten uppnås inom ett år med möjligheter för stora tidsvinster. Det empiriska materialet har även påvisat att uppstartsfasen, systemtypen, testfallens komplexitet och återanvändning är faktorer som kan påverka tidsvinsterna. / This study examines the time savings of an investment in automated regression tests relative to a manual approach. The purpose of this is to produce an underlay for decision making consisting of ROI and break-even calculations which has the intention of reducing uncertainty in case the investment will result in time savings within the systems life span as well as how big these savings can become. To examine this, automated regression tests have been developed where time spent was measured to be used as the invested time. The time it took for the automated tests to execute the studies test cases were compared with the manual counterpart. This has, together with the empirical material from the interviews, formed the basis for ROI and break-even calculations regarding the investment of automated regression tests. The empirical material contributed to the calculations with parameters for test frequency, test amount and life span. Unlike previous research, this study uses calculations with a higher amount of test frequencies which showed that even with a relatively low test frequency, automated regression tests have good opportunities for a positive ROI. With a medium to high test frequency, the break-even point was reached within one year with possibilities for great time savings. The empirical material has also shown that the start-up phase, system type, test case complexity and reusability are factors that can affect the time savings.

Master of Agribusiness / Department of Agricultural Economics / Jason Bergtold / Efficiency and technology are increasingly important selling points for combine harvesters. Diesel-electric hybrid drives have taken hold in the construction equipment industry, and are providing marketable efficiency benefits for some heavy equipment customers. This thesis explores the technical and economic feasibility of utilizing diesel-electric hybrid drives on AGCO combine harvesters. To determine the technical feasibility of utilizing diesel-electric hybrid drives on AGCO combine harvesters, a search was conducted for prior literature relating to the use of electric drives on other heavy, off-highway equipment. This information, coupled with data provided by experts in the field, was used to determine if electric drives could fulfill the unique requirements of combine harvesters, and be practically utilized for this application. To determine the economic feasibility of utilizing diesel-electric hybrid drives on AGCO combine harvesters, an optimization model was constructed to seek out the most economically viable configuration of electric drives for this application. The model takes in to consideration the different use-cases in which this equipment is expected to perform, as well as the component costs and operating efficiencies of both the drives in place currently and the proposed electric drives. The outcome of the model was then utilized to compare the best-case configuration to the minimum requirement for economic feasibility. The technical feasibility assessment conducted for this thesis led to the conclusion that it would be technically feasible to utilize electric drives on a combine harvester. There are commercially available electric drive components which are suitable for use in the environment that this equipment is expected to operate in, and a prototype combine harvester having electric drives has previously been constructed. The economic feasibility assessment conducted for this thesis revealed that it is not economically feasible to utilize electric drives on AGCO combine harvesters at this time. Under the current circumstances, the most economically viable configuration would take nearly twice the machine’s usable operating life to provide a benefit to a customer from fuel savings. Sensitivity analysis revealed that significant changes in the price of fuel or electric drive components would be necessary to change the outcome of this study.

<p>This paper presents the feasibility study of setting up the new potting tray production line based on the two alternatives: partly outsource a process in the production line or wholly make all processes in-house. Both the qualitative and quantitative approaches have been exploited to analyze and compare between the make or buy decision. Also the nature of business, particularly SMEs, in Thailand has been presented, in which it has certain characteristics that influence the business doing and decision, especially to the supply chain management. The literature relating to the forecasting techniques, outsourcing decision framework, inventory management, and investment analysis have been reviewed and applied with the empirical findings. As this production line has not yet been in place, monthly sales volumes are forecasted within the five years time frame. Based on the forecasted sales volume, simulations are implemented to distribute the probability and project a certain demand required for each month. The projected demand is used as a baseline to determine required safety stock of materials, inventory cost, time between production runs and resources utilization for each option. Finally, in the quantitative analysis, the five years forecasted sales volume is used as a framework and several decision making-techniques such as break-even analysis, cash flow and decision trees are employed to come up with the results in financial aspects.</p>

2009 beslutade det europeiska fotbollsförbundet UEFA att införa regelverket Financial Fair Play Regulations, för att förbättra fotbollens ekonomiska hälsa. Detta som en följd av en allt mer ansvarslös och irrationell pengahantering bland europeiska fotbollsklubbar, med stora underskott och försenade betalningar som konsekvens. Ett avsnitt i regelverket berör de så kallade ”break-even”-kraven, som sätter begränsningar för hur stora underskott klubbar får visa upp.   I vår uppsats har syftet varit att utreda huruvida ”break-even”-kraven är att anse som förenliga med EU-rättsliga konkurrensregler, specifikt art. 101.1 FEUF. Detta då kraven, enligt vår uppfattning, kan anses ha en konkurrenshämmande verkan i form av investeringsbegränsningar och en asymmetrisk effekt på transfermarknaden.   För att kunna utreda den rättsliga giltigheten, har vi använt oss av relevant praxis på EU-nivå inom områdena konkurrensrätt och idrott. Eftersom regelverket är så pass nyutkommet, har det ännu inte hunnit prövas rättsligt på EU-nivå. I och med detta, har det för oss funnits stort utrymme för diskussion och hypotetiska scenarion. Vår studie av praxis har visat att bestämmelserna kan bedömas vara förenliga med EU-rätten, trots en konkurrensbegränsande verkan. I vår analys har vi därför, utifrån befintliga förutsättningar, diskuterat huruvida vi anser att ”break-even”-kraven ska bedömas vara förenliga med art. 101.1 FEUF, även om de kan anses ha en konkurrenshämmande effekt. Vi har vägt in både ekonomiska och sportsliga faktorer i vår analys, och har även diskuterat möjligheten till alternativa tillvägagångssätt.

In an effort to maximize yields, many soybean growers have begun moving to intensive, input-based soybean management systems. However, limited reliable information exists about the effect of these inputs on soybean yield. The purpose of this study was to evaluate the effect of individual inputs and combinations of inputs as part of high-yield management systems on soybean seed yield and to determine the effect of one of these inputs, lactofen, on soybean physiology. Small plot studies were established in nine states across the Midwest. A number of commercially available soybean inputs were evaluated individually and in combination to determine their effect on soybean yield and quality. Lactofen and comparison treatments were applied to soybeans at multiple growth stages and yield and yield components were determined. When examined across environments, input-intensive combination treatments increased soybean yields from 3.9 to 8.1 %. However, break-even economic analysis indicated that the combination (SOYA) treatments evaluated had 0% probability of breaking across a wide range of yield levels and soybean prices, due to the high input costs. The foliar insecticide showed the highest probability of breaking even across a range of yield levels and crop prices (40% to 99%). Yield increases and breakeven probabilities were generally greatest in the northern states (Minnesota, Wisconsin, Michigan) and similar in the central and southern states. Lactofen application did not kill the apical meristem and had minimal effect on yield components compared to untreated soybeans at any growth stage. Meristem removal increased node m-2 in some environments, but did not increase pods m-2 and seeds m-2 or seed yield.

Neste trabalho, realizamos um estudo analítico da estabilidade dos sistemas dinâmicos p-fuzzy. Estabelecemos condições necessárias e suficientes para existência de ponto de equilíbrio para sistemas p-fuzzy unidimensionais e bidimensionais e derivamos condições para estabilidade deste ponto. Vimos que, uma condição suficiente para existência de ponto de equilíbrio é uma mudança de sinal na saída do controlador. Este trabalho mostra ainda, que a estabilidade de um ponto de equilíbrio depende, principalmente, das variáveis de entradas e saídas do sistema baseado em regras fuzzy associado ao sistema p-fuzzy. Além dos diversos resultados matemáticos encontrados, com demonstrações rigorosas, realizamos inúmeros experimentos computacionais e obtivemos resultados que atestam a veracidade de da teoria aqui proposta. Apresentamos ainda, algumas aplicações em Biomatemática onde podemos comprovar, em situações concretas, a eficácia, versatilidade e robustez da teoria desenvolvida / Abstract: A p-fuzzy dynamic system is a system whose dynamics is obtained through a fuzzy rule-based systems. ln this work we present an analytical study of the stability of p-fuzzy dynamic systems. We establish necessary and sufficient conditions to existence of equilibrium point for one variable and two variable p-fuzzy systems and, we derive conditions for stability of this point. We saw that, a sufficient condition for existence of equilibrium point is a change of signal in the output of the controller This work still shows, that the stability of an equilibrium point depends, mainly, fuzzy rule-based systems's input-output. Many mathematical results has been found and demonstrated rigorously. We still made many computational experiments and its results show that all developed mathematical theory is efficient. We still present, some applications in Biomathematics where we can prove, in real situations, the efficiency, versatility and robustness of the developed theory in this work / Doutorado / Doutor em Matemática Aplicada
