The thesis deals with warranty costs and their prediction when providing one-dimensional and two-dimensional warranties. This thesis focuses on the presentation of practically applied methods and procedures which enable suppliers and manufacturers to get the information necessary for rational decision making while providing warranties for complex products as early as in the initial stages of their life cycle. The thesis starts with a concise summary and evaluation of a present state of the issue. In the first part of the thesis the possibilities of warranty costs prediction for complex products are analyzed when using one-dimensional and namely two-dimensional quality warranties. In this part there is a detailed analysis of different possibilities when predicting systems and items reliability. Next, there is introduced the way of integrating warranty costs prediction into the FMEA/FMECA method. In the second part of the thesis there is specified the procedure for determining the moment of warranty period termination using two-dimensional warranty in case sufficient data from complaint procedure is not available. In the third part the time development of warranty costs and related measures are determined, and the way of prediction of their time development is suggested. The way of continuous monitoring, and evaluating warranty costs and related measures are also introduced in this part of the thesis.

Warranty claims from a consumer perspective in the context of sales of goods. This thesis addresses the issue of claims under warranty by consumers, which I suppose every one of us has done at least once in our lifetime. This work is divided into four chapters and it aims to describe, in depth, the contemporary legal regulation of the provision § 19 of the Consumer Protection Act in connection with the provisions of the Civil Code, mainly its special provisions on the sale of consumer goods. The first chapter is concerned with the general definition of the regulation impacting this domain. Specifically, it introduces the consumer sales contract, its incorporation within the general regulation of sales contracts and it goes even further in referencing the EU legal regulations affecting consumer rights concerning faulty goods and certain aspects of warranty claims. In the second chapter I define the terms 'consumer', 'trader', 'goods' and 'faulty goods' in connection with the consumer purchase contract and its interpretation within the context of the Consumer Protection Act and the Civil Code. In the third chapter I define the most fundamental term of the thesis - that of a 'claim under warranty'. With respect to this term, I analyze the essentials of claiming under warranty. Specifically, they...

A abertura do mercado brasileiro e o fenômeno da globalização observado nos últimos anos, influenciaram em que as quatro tradicionais empresas do setor automobilístico (VW, Ford, FIAT e GM) passassem a dividir a participação de mercado brasileiro com os concorrentes estrangeiros. Devido a este fato, a demanda por qualidade e confiabilidade nos produtos oferecidos cresceu continuamente. Nenhuma empresa gosta de gastar com garantia, isto significa que algo saiu errado, um cliente está insatisfeito e isto custará à montadora. Deste modo as empresas automotivas necessitam desenvolver veículos com qualidade superior e com menores custos e para isso utilizam diversas ferramentas de engenharia. Atingir a satisfação dos clientes, melhorar a qualidade de seus produtos, reduzir custo de garantia tem sido a missão de todas as empresas no mercado brasileiro e em especial nas empresas do setor automobilístico, já que os principais fatores na decisão de compra de um veículo tem sido preço e confiabilidade, torna-se necessário oferecer cada vez mais opções de escolha para os clientes e acredita-se que a extensão da garantia oferecida pela empresa automotiva pode ser um fator decisivo de compra. Portanto o objetivo deste estudo é desenvolver um modelo para descrever o comportamento de um produto e predizer sua confiabilidade no campo. O modelo considera a utilização dos dados de reclamações de garantia, incluindo a consideração da existência de veículos que não apresentaram falhas ao final deste período. De posse da estimativa da confiabilidade do veículo ou subsistema e considerando os recursos gastos com falhas no período de garantia, propõe-se um modelo de análise baseado nos conceitos da Teoria da Decisão, que permite avaliar o efeito da extensão da garantia sobre o valor monetário economizado do total reservado para os gastos com garantia. Esta análise subsidia unicamente a tomada de decisão estratégica a respeito da viabilidade da extensão da garantia de um veículo. O modelo ora proposto é aplicado no intuito da extensão da garantia do conjunto motor e transmissão de um veículo popular. / As the Brazilian market opened to foreigner automakers and the phenomenon of globalization started some years ago, the four traditional automakers began to share its market with many others competitors. As a result, demand for quality and reliability on products offered to the customers grew continuously and it is more perceptive on the automobile business. Nobody likes warranty expenses; it is a universally recognized evil. It means that something went wrong, a customer is not satisfied and it probably will cost to the manufacturer. As it happens, automakers need to develop vehicles with superior quality, less manufacturing costs and better processes, shorten development process and to accomplish this goal it is necessary to use engineering tools available as much as possible. Many companies are setting as their goal: customer satisfaction, quality improvement, warranty cost reduction and it happens more often on the automobile market that is because reliability and warranty became one of the key points when making decisions of purchasing a vehicle. Today it is necessary to offer more options to the customers so they can decide which one is the best deal for them. It is believed that warranty extension already offered by some companies in this market can be a significant differential on the moment of a purchase decision in buying a vehicle. Therefore, the main objective of this study is to develop a model to describe the behavior of a product and predict its reliability in the field. The model considers the use of warranty claims and also the use of a number of vehicles which did not have any warranty claim in the subsystem under analysis. As one have the subsystem predicted reliability and the expenses on warranty failures occurred during their warranty period, it is possible to draw a model based on the concept of Decision Theory which allows the analysis of warranty extention effects over the warranty accrual. This analysis only helps on the decision making strategy regarding the warranty extention feseability. The model proposed on this study is applied for warranty extention of the subsystems engine and transmission.

Le logiciel est un objet particulier dont l'ampleur des conséquences liées à sa spécificité n'est pas toujours mesurée. L'objectif de cette thèse est de découvrir le régime applicable au logiciel lorsque celui-ci ne remplit pas ses fonctions. Bien immatériel, création et outil, il est le reflet parfait d'une dualité qui le soumet tant à la propriété intellectuelle qu'au droit des obligations. Tenant compte de cette nature spécifique, cette thèse propose de découvrir le régime juridique applicable aux dysfonctionnements du logiciel en étudiant à la fois les régimes légaux existants, la jurisprudence, et la pratique contractuelle confrontés aux défaillances du logiciel. À cet égard, le recours aux règles proposées ne constitue qu'une première étape dans la compréhension du régime, notamment au regard de la détermination des obligations et de la responsabilité des acteurs concernés. En réalité, la rigidité des concepts du droit des obligations ne permet pas de résoudre toutes les difficultés juridiques qu'il suscite. Au final, c'est donc essentiellement dans les ressources de la pratique contractuelle qu'il importe de rechercher des éléments de réponse aux questions soulevées par les dysfonctionnements du logiciel. Objet atypique, à la fois création et outil, les principes appliqués au logiciel résultent plus d'emprunts ponctuels que d'une catégorie juridique prédéterminée. De ce fait, le régime juridique applicable aux dysfonctionnements du logiciel ne serait-il pas entaché d'une précarité que seule une prise en compte générale par le droit civil serait susceptible de résorber. / The software is a particular object whose magnitude of the consequences related to its specificity is not always measured. The objective of this thesis is to discover the rules applicable to software when it does not fulfill its duties. Although intangible, and creation tool, it is a perfect reflection of a duality which subjects it to intellectual property as well as the law of obligations. Taking into account its specific nature, this thesis proposes to explore the legal regime applicable to software malfunctions, studying both the existing legal systems, jurisprudence, and contractual practice confronted with software failures. In this regard, the use of the proposed rules is only the first step in understanding the system, particularly with regard to determining the obligations and responsibility of stakeholders. In fact, rigid concepts of existing rules does not resolve all the legal difficulties it causes. In the end, so it is essentially in the resources of the contractual practice it is important to seek answers to the questions raised by software malfunctions. Unusual object, both creation and tool, the principles applied to software result from more temporary borrowing than a predetermined legal category. Therefore applicable to the software malfunctions, legal regime would it not marred by an insecurity that only take into account the general civil law would be likely to reverse.

Diplomová práce popisuje vlastnosti a rizika investování do strukturovaných produktů v Německu. Součástí práce je zároveň otestování efektivnosti využití Bonus, Diskont a Outperformance certifikátů při správě finančních prostředků. Analýza ukazuje, že je možné pomocí Diskont a Bonus certifikátů dosáhnout vyššího výnosu očištěného o riziko. Outperformance certifikáty umožňují dosáhnout vyššího výnosu pouze při výrazném růstu (zároveň s vyšším rizikem). Veškeré investice do strukturovaných produktů jsou porovnávány s výnosem u indexu DJ Euro Stoxx 50 (Total Return).
