Повний текст джерелаThe purpose of this Master of Business Administration project is to identify possible expansion capabilities, by researching the most cost-effective two-dimensional barcode technology known as an item unique identification that will allow for tracking Department of the Navy assets from cradle to grave. While the Navy is not 100 percent complete, the Office of the Under Secretary of Defense for Acquisition, Technology, and Logistics mandated that all new tangible and legacy items over $5,000 and/or serially managed, mission critical, or controlled by inventory, must be serialized and registered by 2010. There are two methods that the Navy can use to mark such items: intrusive and nonintrusive. For legacy items, the best method to mark an item would be nonintrusive, due to the criticality of maintaining the integrity of the item for safety reasons. Thus, it was determined that the best marking procedure for legacy items would be metal foil tags, generated by a contracting company, since they are the most cost-effective, nonintrusive marking method.

Повний текст джерелаEnvironmental awareness and increased interest in energy-efficient housing have made the buildings more insulated in Sweden. Usually, it is quite easy to calculate a profit from a greater amount of insulation, in the long term. This is usually the seller’s main argument to why the client should choose the thicker insulation. For a client that wants to build a rental property, it is usually the economy that determines whether a project should be started or not. Hopefully this study will be a help to choose the most economic insulation thickness in walls. The purpose of this study is to investigate where the optimum of wall insulation thickness is in an apartment building for renting which is built on a limited area. Quite often there are requirements for a maximum building area from the municipality, which means that the rentable living space will come smaller when the insulation gets thicker. Qualitative interviews were used to determinate the common wall constructions which the insulation would be optimized for. These walls were placed in a theoretical reference building in which the energy use were estimated using hand calculations where mathematical expressions of a variety of insulation thickness were used. Thereafter, the prices of the walls were calculated using a spreadsheet program called Sektionsdata. A life cycle cost analysis was performed in which the historical statistics on rents, energy prices and interest rates were used. Finally, the optimal insulation thickness was found for each wall type. The wall types chosen were a wall of concrete and brick, a wall of concrete and rendering, a wall of wood and brick and a wall of wood and rendering. Optimal insulation thickness of the wall with concrete and brick ended up at 84mm. For the wall of rendered concrete, the optimal insulation thickness ended up at 88mm. The optimal insulation thickness of the walls of wood could not be found as the wall structure with two and three insulation layers made the walls too isolated in an economic perspective even at a minimal thickness of the layer that was going to be optimized. The study shows that with current building codes in Sweden it is profitable to keep down the wall insulation thickness in an apartment building for renting, built on a limited area.

Повний текст джерелаExcept in Stockholm, local public transport shows a declining trend in spite of an annual total subsidy from the County councils of 10 billion SEK. This is fair enough. Running local bus services in small and medium sized towns in accordance with welfare economic criteria implies among other things a pricing policy which requires subsidization just above 50%, which happens to be the same as the present degree of tax-financing. However, this is just a coincidence, and not a mark of optimality, because it is found that the structure of fares is clearly suboptimal. As regards investment policy it is furthermore confirmed by a questionnaire survey that neither the principals (the County councils) nor their agents (bus companies) use cost-benefit analysis (CBA) for the design of local public transport systems, so the purpose of the thesis is to demonstrate the potential improvements of public transport in small and medium sized towns run on the basis of welfare economics. The operationalization of the welfare economic foundations requires some theoretical reorientation in the particular case of local public transport. A fundamental division of the supply is made between the “merit goods” part of total supply and the “normal goods” part, where benefit is measured by the individual willingness-to-pay. In a case study of the bus transport system of Linköping a number of generally applicable minor improvements are found by the welfare economic approach, which aggregated to the national level would imply a total net benefit which more spectacular projects in the public transport sector rarely can present.

Повний текст джерелаThe aim of this thesis is to develop a method that provides design assistance for District Heating Network (DHN). This tool allows simultaneously the optimization of the configuration and its sizing, thanks to an MINLP formulation (Mixed Integer Non-Linear Programming). Binary variables help to choose the optimal configuration (network layout and technologies of production), whereas continuous variables help DHN sizing (temperature, diameter, velocity, heat exchanger area, thermal generating capacity …). The objective function to minimize is the total cost (capex and opex), subjected to numerous nonlinear constraints (e.g. thermal losses, pressure drop, energy balance).This method enables to design temperature cascade between consumers, when consumer temperature requirements are different, and also looped network (only one pipe in one trench). It helps also the decision to connect (or not) consumers to the main network and also the location(s) and type(s) of the heating plant. Moreover, the arbitrage between heat losses and pressure drops is taken into account thanks to physical considerations (non-linear equations). Eventually, it is possible to design 4th generation DHN and prove their financial profitability over the long terms (30 years). First a multi-step resolution strategy is proposed to ensure finding global optimum of the complex MINLP problem. Then academic study cases are analyzed to underline the numerous assets of the formulation. Finally, the optimal design compared to an existing DHN ensures the consistency of the method and allows to build a study case at a wider scale, which can be solved thanks to the comprehensive strategy developed. The design assistance method is available for initial design as well as for extension of existing DHN

Повний текст джерелаThe current electric power system isfacing the challenges of environmental protection,increasing global electricity demand, high reliability requirement, cleanliness of energy, and planning restrictions. To evolve towards green and smart electric power system, centralized generating facilities are now being transformed into smaller and more distributed generations. As a consequence, the concept of microgrid emerges, where a microgrid can operate as a single controllable system and can be assumed as a cluster of loads and distributed energy resources, which may include many renewable energy sources and energy storage systems. The energy management of large numbers of distributed energy resources is needed for reliable operation of microgrid system. Therefore, energy management is the fundamental part of the microgrid operation for economical and sustainable development. In this regard, this thesis focuses on proposing energy management optimization models for optimal operation of microgrid system that include proposed practical Li-ion battery degradation cost model. These different energy management models include objective functions of operating cost of distributed generators, emission cost of conventional generation source, maximum utilization of renewable energy sources, battery degradation cost, demand response incentives, and load shedding penalization cost, with microgrid component and physical network constraints. A comprehensive conceptual seven layer model is also developed to provide standardized insights in implementing real transactive energy systems

Повний текст джерелаGlobally, the construction industry is one of the main sectors responsible for primary energy consumption and CO2 emissions. In Brazil, about 48.5% of electricity consumption comes from the building sector, with commercial buildings representing 14.4% of this value. In this context, the characteristics of the façade - considered the greatest constructive element in commercial buildings - directly influence energy consumption and the environmental impacts of this type of building. As a result, investment in policies that promote energy efficiency can be considered the key to sustainable development and climate change mitigation. Several global agreements, such as the Kyoto Protocol, the European Directive 2010/31 / EU (with the well-known \"20-20-20\" objectives) and Annex 57, from the International Energy Agency (IEA), have established limits to CO2 emissions, energy consumption reduction, investments in production of renewable energy and methods for assessing a building´s incorporated energy and CO2 emissions. Among the systems used to evaluate and create more sustainable buildings, the Life Cycle Assessment (LCA) stands out. This technique can make a holistic assessment of a product´s entire life cycle and identify issues that impact the environment. This method makes it evident that the energy consumption yielding from the building´s use phase is an important factor in the building´s life cycle, bringing significant environmental impacts. Among all the tools available to integrate the evaluation of energy with environmental performance, MARS-SC Methodology and Cost Optimum Analysis stand out on this research. The first is a multicriteria analysis, which performs the normalization of environmental impacts by indicator´s categories, while the second one provides an optimization study between a baseline scenario and several energy rehabilitation ones, considering cost, CO2 emissions and energy resources consumption. The objective of this research is to assess the integrated energy consumption, environmental impact and cost of different life cycle façade solutions (288 scenarios) from office buildings in Brazil through methodologies of multi-criteria analysis (MARSSC) and Cost Optimum Analysis. For the analysis scenarios, the energy consumption and material quantities - which generated the environmental impacts and costs - were calculated. The results showed the importance of a building´s life cycle´s use phase, which represented an average of 70% in CO2 emissions. This impact was reflected in the life cycle cost of construction solutions, as the scenarios with higher energy consumption in the use phase caused the major operating costs impact. Among the parameters evaluated, for each scenario, the type of façade and the window-to-wall ratio were the ones that most influenced the results in all aspects (energy, environmental and cost). The Traditional Façade scenarios obtained the best performance, while the Curtain Façade, WWR 80%, colorless glass without shading devices had the highest energy consumption, more expensive and more environmentally impacting. In contrast, the use of shading devices, despite of increasing CO2 in the pre-use phase, reduced energy consumption in the building´s use phase. This fact showed, on ending accounts, reductions in the total environmental impact and cost of construction solutions, i.e. the reduction of operating costs surpassed the cost of construction. Thus, the premise of having energy efficiency linked to the architectural project can guarantee better buildings, not only energetically, but also environmentally and economically. This may impact not only one building, but a whole group of buildings within a neighborhood, a city or even a country.

Повний текст джерелаThe aims of this work is to show the contributions that the interaction between real options theory and target costing may offer in the pricing process. The justification for this issue lies in the lack of studies on the subject, because there are many works on the target costing and the real options theory, however, in the literature no studies were found that explicitly describe the interaction between the real options theory and target costing. To get to the objective of the work, spoke out about the pricing from the perspective of cost, the investment analysis and the economic viewpoint, it was demonstrated throughout the work the various techniques and theories on pricing, supported on a deductive method, descriptive and exploratory. At the end of the work, using the assumptions of target costing as premises of managerial flexibility of real options theory, proved a great contribution to the pricing process because decision makers might have a far more complete variables that impact the price and make the right decision on market possibilities
O presente trabalho tem como objetivo mostrar as contribuições que a interação entre a teoria das opções e o target costing podem oferecer ao processo de precificação. A justificativa para este tema reside na escassez de trabalhos sobre o assunto, pois, existem muitos trabalhos sobre o target costing e sobre a teoria das opções reais, porém, na literatura não foram encontrados trabalhos que descrevam explicitamente a interação entre a teoria das opções reais e o target costing. Para chegar-se ao objetivo do trabalho, discorreu-se sobre a precificação pela ótica de custos, pela análise de investimentos e pela ótica econômica, ou seja, demonstrou-se ao longo do trabalho as diversas técnicas e teorias sobre precificação, amparado em um método dedutivo, do tipo descritivo e exploratório. Ao final do trabalho, utilizando os pressupostos do target costing como premissas de flexibilidade gerencial da teoria das opções reais, demonstrou-se uma grande contribuição ao processo de precificação pois, os tomadores de decisão puderam ter uma visão bem mais completa das variáveis que impactam no preço e tomar a decisão correta via as possibilidades de mercado

Повний текст джерелаWe then undertook a study to examine the incidence of hip fracture In Singapore from 2000 to 2017. We observed several important trends in the occurrence of hip fractures in this study. During the period 2000-2017, absolute numbers of hip fractures continued to increase, with a mean annual increase of 71 fractures per 100,000 and an Average Annual Percentage Change (AAPC) of 3.5% (95% CI: 3.3, 3.8). Nevertheless, the crude fracture rate per 100,000 declined in both men and women, indicating that the increase in absolute number of hip fractures was due to an increase in the numbers of women and men at risk for hip fracture. When crude rates per 100,000 were age-adjusted, fractures trends declined even more steeply, indicating the major contribution of the aging Singapore population to the increase in total number of fractures. With the available information on patients’ knowledge, attitude and practice, as well as the cost burden of fracture management in Singapore obtained from the studies as conducted in the thesis, we therefore undertook a fracture liaison service program (OPTIMAL) to prevent recurrent fractures from 2008 to 2016. The OPTIMAL program is a clinician champion-driven, case coordinator-run secondary prevention program for osteoporotic fractures. The program strives to narrow the prevalent care gap in osteoporosis care through a judicious combination of fracture case finding, appropriate assessment and evaluation, patient education on osteoporosis and risk factor management, education on nutrition, fall prevention and exercises for muscle strengthening, balance and coordination, in addition to the use of effective anti-osteoporosis pharmacological agents. The most important finding of this study was the reduction in all sites fracture risk by 41% and hip fracture risk by 47.1% of patients enrolled into the OPTIMAL program when compared with non-enrolees after two years. The absolute risk reduction in hip fracture rate was 7.67% (15.58% in non-enrolees versus 7.93% in OPTIMAL enrolled patients). The absolute reduction in fracture risk was 9% at 5 years. The OPTIMAL program prevented 77 hip fractures for every 1000 participants and reduce mortality by 40% over five years. This led to significant gains of 228 QALYs per 1000 patients. Patients in the program incurred higher costs due to costs of the intervention, BMD test, and osteoporosis treatment, but preventing subsequent hip fractures also saved costs. Discounting costs and benefits at 5 % per year, the program cost $5,607 more and gained 0.228 QALYs per patient, with an incremental cost-effectiveness ratio (ICER) of $24,636 per QALY gained. These results compared favourably with other observational studies and randomised controlled trials of similar fracture liaison service program (8). Taking together with the reduction in fracture, this projected good return of investment would support the cost-effectiveness of implementing such program in Singapore. Therefore, the overall results from the studies as presented in the thesis would indicate that with the aging population, there is a likelihood of increased osteoporosis-related fractures. This projected increase is expected to impose heavy financial burden to the health care system in Singapore. However, with a coordinated approach in managing osteoporosis as shown by the OPTIMAL program implemented in Singapore, it may be possible at least to damper the clinical and financial impact of osteoporosis-related fractures. The results from the studies in this thesis would also provide an example of tackling the problem of increased osteoporosis-related fractures faced by other countries, particularly in the Asia-Pacific region.

The ascending of carbon dioxide density is the main reason causing the global warming which occasionally results in extremely abnormal weather. Due to the decreasing capacity of fossil materials on earth, practitioners and researchers now pay more attentions on the renewable energy such as solar and wind power. Recent years, Taiwan government intrigued the development of wind power industry. This thesis is devoted to find the optimal placement of wind turbines in a wind farm. There are many factors affecting the efficiency of wind power production. Among them, wake effect is the most significant. Therefore, the wind power production efficiency does not necessarily grows with the increasing number of installed wind turbines. This thesis applied a hyper-heuristic algorithm combining several metaheuristics to construct an optimal wind turbine placement considering wake effect influence. Finally, we compare our approach with existing works in the literature.

The use of public transportation in the city of Kaohsiung is low due to the incomplete network of routes and insufficient quality of transport service. According to the report “Survey of daily use of transportation modes” by the Ministry of Transportation and Communications, Taiwan in 2010, the utilization rate of individual transport modes in Kaohsiung reached 83%; however, the utilization rate of public transport modes only accounted for 6%. In order to increase the riderships of public transport and improve the availability of public transit network, the government started to build the light rail transit in June 2013. This study investigates the acceptance of the light rail transit by conducting questionnaire surveys for those who took bus 168 designed for light rail transit routes. Four modes of public transportation including light rail transit, mass rapid transit, bus rapid transit, and bus are compared and chosen by respondents. In addition, this study constructs a mathematical programming model concerning operating costs to solve the optimal operations of circle light rail transit with the objective of the maximum operating profit. The results show that the transit bureau should reduce the departure frequency when transit riderships reach only the 30-50% of planned targets so as to reduce the operating loss. Nevertheless, the frequency could be increased when riderships reach the 60-100% of planned targets. This study provides practical suggestions for the transit bureau in the decision-making process in the operation of light rail transit.

End stage renal disease (ESRD) has been a widespread disease in many countries, especially in Taiwan. According to statistics from the Taiwan Society of Nephrology in 2002, Taiwan ranks second globally in the prevalence and also has the highest incidence of ESRD. In addition, although ESRD patients occupy only 0.15% in the whole health insurance in Taiwan, it costs 7.2% (the highest of whole diseases) of the expense of health insurance. In other words, it is known that the resources and money spent in this disease become a huge burden in the society. Hence, this paper examined the cost-effectiveness of ESRD treatment for patients to make them treated with better cost-effectiveness treatment modalities. The Markov-chain model was used to study the influence of substitutive policies on the overall cost-effectiveness of the ESRD treatment program. After analyzing the cost-effectiveness of the treatments, a mathematical model was constructed to allocate the patients to maximize the effectiveness under the limited funds and to achieve their best QALYs (quality-adjusted life-years). The result shows that Peritoneal Dialysis is the treatment with better cost-effectiveness; therefore, various policies in the budget allocation model are constructed to analyze how the policy will change under different parameters by using sensitivity analysis. The method provides the government a reference for promoting popularization program to change patient proportions in the specific treatment.

In recent years, the agriculture in Taiwan has been fast diminished, especially after joining WTO and the ECFA. Meanwhile, the government has managed to promote the development of the value-added agriculture: eco-tourism. According to the Council of Agriculture, in 2007 the share of agriculture in GDP is 1.45%. But if counting the 1st, 2nd, and 3rd levels of agriculture-related industries, the share is about 11 %. In 2010, the share is slightly increased to 11.21%. As can be seen, the added value of agriculture effectively increases farmers' income and their competitiveness. The development of eco-tourism majorly relies on the local ecological resources. However, the promotion plan of eco-tourism should not only consider the comparative advantages between the eco-tourism and agriculture, but also the ecosystem services of different agricultural crops production process. For example, the government of Nicaragua cooperated with the Global Environment Facility (GEF) on subside farmers who develop their farms with the function of ecosystem services by increasing the ecological diversity, water conservation, and the carbon sequestration effect, etc (Pagiola et al., 2007). In addition, it is important to consider the human impact on the ecological protection areas, transportation routes, species rarity and other indicators. Currently, Taiwan has no specific studies integrating multiple-oriented indicators to provide the local government the information of planning the regional economic development. Therefore, in this study, the Geographical Information System (GIS) was applied to integrate indicators such as land use, geological environment, boundary maps of towns and villages, transportation facility, and social economic information. By applying cost-benefit analysis, the agricultural output value per unit of land, the agro-ecosystem service value, tourism output value, leisure value were evaluated to effectively select the optimal farmlands to be developed as an ecotourism area, which may help to accelerate economic prosperity, improve the balance of regional development, and provide employment opportunities.

According to the official website information in 2014, the total population in Puli Township is 85,445, of which 26% is engaged in agriculture. The major agricultural products are rice, water bamboos, edible red sugar canes, and flowers. Agricultural industry is an important economic activity in Puli. However, after Taiwan participated into the World Trade Organization (WTO) in 2002, the agricultural sector suffered a severe impact. The development of leisure agriculture to decrease the substitutability from the foreigner industry can enhance its competitiveness. Therefore, in recent years, the transformation of agriculture into leisure farm has developed rapidly. According to the Council of Agriculture, the estimated visitors to the leisure farms exceeded 15 million and the business created the value up to NT$ 8 billion in 2012. However, when the government promote the leisure agriculture development, not only the comparative advantage of agricultural output value and tourism output value but also the ecosystem services in the production process of different agricultural crops should be considered. For example, the government of Nicaragua and the Global Environment Facility (GEF) cooperated on subsidies for farmers for making farmlands developing the function of ecosystem services to increase the ecological diversity, water conservation, and the carbon sequestration effect (Pagiola et al., 2007). In addition, to manage the development of the leisure industry should also consider the geographical and environmental conditions, transportation convenience, the socio-economic background, and other indicators. Currently, Taiwan has not had specific studies integrating multiple-oriented indicators to provide the local government to plan the regional economic development. Therefore, in this study, the Geographical Information System (GIS) was applied to integrate indicators such as land use, geological environment, boundary maps of towns and villages, transportation facility, and social economic information. By applying cost-benefit analysis, the agricultural output value per unit of land, the agro-ecosystem service value, tourism output value, leisure value were evaluated to effectively select the optimal farmlands to be developed as a leisure farm, which may help to accelerate economic prosperity, improve the balance of regional development, and provide employment opportunities.

Повний текст джерелаWe live in an era of digital transformation and, the importance of Technologies of Information and Communication in today's societies is increasing. The access and use of these technologies have socioeconomic impacts and, the benefits cover several sectors. The European Union has created different initiatives to improve and increase connectivity to faster communication networks and, at affordable prices. In this way, optical fiber plays a fundamental role due to its advantages, such as higher speed, better connectivity, more signal stability, and greater infrastructure durability. However, there is a visible difference in access between cities and less populated areas to this type of technology, making it necessary to increase investment in more rural areas. In this context, Portugal created public tenders and, in a partnership with private companies, the access to fiber in rural areas has been increasing. This work aims to measure the costs and benefits of optical fiber installation in Portuguese municipalities with lower population density. Although investment in these places is not as attractive as in cities, the objective is to prove that the benefits outweigh the costs. The methodology used was a cost-benefit analysis, in line with the state of the art in the area and that the European Commission subscribes for this type of project. In addition, an online questionnaire was structured and distributed to the municipalities under analysis, to understand the general opinion regarding fiber optics. In the 63 municipalities analyzed it was verified that the benefits outweighed the costs. On average, for each euro invested there, is calculated a return of 3.49€ (if there was a new fiber connection) or 1.74€ (if there was an upgrade from basic broadband to optical fiber). Thereby, under the assumptions assumed, it has been proved that investment in these rural areas is beneficial.
Vivemos numa fase de transformação digital e a importância das Tecnologias de Informação e Comunicação nas sociedades atuais é cada vez maior. O acesso e o uso destas tecnologias têm impactos socioeconómicos e os benefícios são transversais a vários setores. A União Europeia tem criado iniciativas no sentido de aumentar e melhorar a conectividade a redes de comunicação mais rápidas e a preços acessíveis. Desta forma, a fibra ótica desempenha um papel fundamental, devido às suas vantagens, como maior velocidade, melhor conectividade, maior estabilidade do sinal e maior durabilidade das infraestruturas. Contudo, é visível a diferença de acesso, entre as cidades e as zonas menos habitadas, a este tipo de tecnologia, sendo necessário aumentar o investimento nos locais mais rurais. Portugal, neste contexto, apoiou este investimento através de concursos públicos e, em parceria com algumas empresas portuguesas, o acesso a fibra ótica tem vindo a aumentar nas zonas rurais. Este trabalho propõe uma forma de mensurar os custos e os benefícios da implementação da fibra ótica em municípios portugueses, com menor densidade populacional. Apesar do investimento nestes locais não ser tão atrativo como nas cidades, o objetivo é perceber se os benefícios superam os custos. A metodologia usada foi uma análise de custo benefício, em linha com o estado da arte da área, e que a Comissão Europeia subscreve para este tipo de investimentos. Foi ainda estruturado e distribuído um questionário online junto dos Municípios em análise, com o intuito de perceber o nível de conhecimento e opiniões relativamente à fibra ótica. Nos 63 municípios analisados, verificam-se benefícios superiores aos custos. Em média, por cada euro investido calcula-se um retorno de 3.49€ (no caso da instalação de fibra ótica) ou 1.74€ (no caso de ter existido um upgrade de banda larga básica para fibra ótica). Dentro dos pressupostos assumidos conclui-se que o investimento nestas zonas rurais é benéfico.
