The thesis contains 3 repairable systems and 2 replacement systems: First a repairable system is considered with Markovian deterioration and imperfect repair, carried out at fixed times. We look for optimal strategies under certain conditions. Two optimality criteria are considered: expected discounted cost and long-run average cost. Conditions are found under which the optimal policy is a control-limit policy as used by Derman or Ross. We explicitly explain how to derive this optimal policy; numerical examples are given, too. The special case of unbounded cost is also studied. With the first model the state space is numerable but with the second it is not. With the fourth model the system occurs a shock process and is only inspected after such a shock. Models 3 and 5 are replacement systems with Morkovian deterioration and finite state space {0,...,N}. A system in state N is considered to be in a very serious situation. Hence there is the condition, e.g. stipulated by law, that the percentage of all replaced machines in state N in the group of all replaced machines may not be larger than 100 epsilon for a fixed epsilon in [0,1]. We prove that a generalized control limit policy maximizes the expected running time of a machine and we explain explicitly how to derive this optimal policy. Illustrated numerical examples are given.

This master´s thesis is focused on evaluation of company´s economic performance. Evaluation is done by standard methods of financial analysis and modern method Economic Value Added. Theoretical part describes methods and procedures that can be used for evaluation of economic performance. Practical part deals with evaluation of economic performance of the company KOH-I-NOOR PONAS Ltd.

<p>Traditional and cont emporary studies of spatial administrative systems are reviewed. Economic, political and historical factors are related to patterns of administrative areas. The hypothesized relationships are tested using data for the Ontario Hydro-Electric Power Commission. Linear and quadratic models relating functional costs to workload of the administrative areas are offered. The quadratic models incorporate the concept of the long-run average cost curve. A theoretical relationship between the shape of an administrative area and the level of economic efficiency is tested. Linear programming is used to simulate administrative patterns. Four indices are used to describe and compare the patterns. One of the indices, the weighted mean, is used to operationalise Pred's Behavioural Matrix . Recommendations are made for future work. </p> / Thesis / Doctor of Philosophy (PhD)

The aim of this thesis is to perform an analysis of MODUS ltd. which will be based on evaluation of its economic performance and finding out the causes of the current situation. In the first part, there is basic theoretical determination of the analysis and all of its appurtenances. The second part emphasizes on an extensive characteristics of the chosen company, so that it is possible to perceive the calculated determinants from the right perspective. The third part includes the performance of the analysis of a given company and a well-arranged recording and subsequent evaluation of the results obtained. The thesis is concluded with the evaluation of the economic situation of the company based on the results of the analysis and with the recommendation of particular measures which would increase the economic efficiency and effectiveness in the future. Furthermore, there is a summary of models and determinants used with an indication of their advantages and disadvantages.

The aim of this dissertation is to design finance management model and then to test it in real company operated in field of facility management (property and asset management in the field of real estate’s). Designed model works with instruments of financial analysis and investment management. Key hypothesis of the model tells that return on equity should by higher or equal in comparison to weighted average cost of capital. This hypothesis is used not only for effective financial management of the company but also for its smaller units (business centres). Part of the dissertation is definition how to implement and use the model (31 steps for the implementation). Designed model (and hypothesis as well) is verified on the case study.

本研究的目的在於探討企業的財務結構決策是否攸關市場價值。根據加權平均資金成本與企業評價模式相關文獻基礎，產生下列三個假設：(1)資本結構與平均資金成本存有關聯性；(2)最適資本結構必須存在，以使平均資金成本達到最低；(3)平均資金成本與企業價值也存有關聯性。故本研究之實證議題探討：(1)平均資金成本與資本結構的關聯性以及最佳資本結構是否存在(2)加權平均資金成本、權益資金成本與企業價值的關聯性(3)資本結構與平均資金成本之關聯性對企業價值的影響。 本研究使用民國80年至88年台灣證交所股票上市公司作為樣本資料，主要的實證結果如下。財務結構與平均資金成本具有顯著的負向關係，故實證結果並不支持M-M 的槓桿無關論。在十八個產業中，大約半數的產業存在最適資本結構。此外，相對於平均資金成本而言，權益資金成本與股價報酬呈現顯著的負向關係，且具有較高的解釋力；這個結果強調了權益資金成本在解釋股價報酬上的重要性。 本研究亦發現，企業經理人無法透過財務結構的調整來極大化企業的價值，經理人應該考量其他方式來極大化公司的價值。 / The purpose of this thesis is to investigate whether financial structure decisions of a firm are relevant to its market value. Three assumptions underlie the literature on weighted average cost of capital and firm valuation models. First, the linkage exists between the capital structure and the average cost of capital. Second, in order to minimize the average cost of capital, the presence of optimal capital structure is required. And third, the relationship exists between the average cost of capital and firm values. The empirical issues explored in this thesis therefore include: (1) The relationship between the average cost of capital and the capital structure and the presence of optimal capital structure; (2) The association between weighted average cost of capital, cost of equity capital and firm values; and (3) The influence of capital structure-average cost of capital relationship on firm values. Using the listed companies on Taiwan Stock Exchange over the period of 1991 to 1999 as the sample, major empirical findings are as follows. The empirical evidence indicates that financial structure is significantly negatively associated with the average cost of capital, which in turn may imply the M-M leverage irrelevance proposition is not supported by the sample firms examined. About half of the 18 industries examined in this study suggest the presence of optimal capital structure. Furthermore, compared to the average cost of capital, the cost of equity capital is found to be significantly and negatively associated with stock returns and has better explanatory power. This emphasizes the importance of the cost of equity capital in interpreting the behavior of stock returns. In addition, this thesis also finds that managers’ influence of maximizing firms’values through adjusting their firms’financial structures is limited. Managers may have to find avenues other than financial structure decisions to maximize the values of their firms.

The challenge in this process is to establish a remuneration that guarantees the lowest cost with the greatest benefit to the customers and at the same time provides the maintenance of the economic balance and the incentive to expand the services provided by the concessionaires. The complexity of the study becomes evident when we verify the great dispersion of values proposed in the contributions sent to the Sanitation and Energy Regulatory Agency of the State of São Paulo (ARSESP) during the public consultation process. In this sense, the different approaches used by other regulatory agencies also make it difficult to establish a standardized solution to the problem. In this way, we analyzed initially the methodology defined by the ARSESP, the contributions received during the public consultation process carried out by the agency and some references of national and international regulatory practices. Finally, we sought to solve the issue by proposing a methodology considered adequate to estimate the weighted average cost of capital for the natural gas distributors in the state of São Paulo. / O objetivo deste trabalho é propor uma metodologia para a determinação do custo médio ponderado de capital a ser empregado pela agência reguladora no processo de revisão tarifária das distribuidoras de gás natural do estado de São Paulo. O desafio nesse processo é estabelecer uma remuneração que garanta o menor custo com o maior benefício para os clientes e ao mesmo tempo proporcione a manutenção do equilíbrio econômico e do estímulo a ampliação dos serviços prestados pelas concessionárias. A complexidade do estudo torna-se evidente ao verificarmos a grande dispersão de valores propostos nas contribuições enviadas a Agência Reguladora de Saneamento e Energia do Estado de São Paulo (ARSESP) durante o processo de consulta pública. Nesse sentido, as diferentes abordagens utilizadas por outras agências regulatórias também dificultam a definição de uma solução padronizada para o problema. Desta forma, analisou-se inicialmente a metodologia definida pela ARSESP, as contribuições recebidas durante o processo de consulta pública realizado por esta agência e referências das práticas regulatórias nacionais e internacionais. Finalmente, procurou-se solucionar a questão propondo uma metodologia considerada adequada para estimar o custo médio ponderado de capital para as distribuidoras de gás canalizado do estado de São Paulo.

The theme of the thesis is to compare the accounting and economic value added. The theoretical part describes the value added and its determinants. It is defined as economic value added. The first is the basic formula for calculating the economic value added, and the identification of variables that are needed to calculate. The most important variable is the weighted average cost of capital. The next section is defined by other methods which can calculate EVA. The practical section provides the necessary methods and procedures for calculating the financial and economic value added. Methods chosen for the calculation were: the CAPM method, Modular method and Benchmarking diagnostic system of financial indicators INFA.
