Využití metod vícekriteriálního hodnocení variant pro hodnocení úrazového pojištění / Application of the methods of multi-criteria evaluation of alternatives for assessment of accidental death and dismemberment insurance

ROUHOVÁ, Eliška January 2019 (has links)
Decision making is an inherent part of human life. Every day we decide on little things, but also some more complex problems may appear. In such cases, we need to choose a more complex process leading to the final decision. To do so, many multiple-criteria decision-making methods can be used. These methods will be explored in this thesis. They will be used to select accident insurance according to the preferences and requirements of several respondents. Accident insurance protects the insured person against the impairment of their life caused by the consequences of their injury. Accident insurance is a commitment for many years, so its choice needs close attention. The choice of the insurance can be assessed based on of several criteria. Designing a model of multi-criteria decision-making strategy was the main goal of this diploma thesis. The thesis is divided into two parts - the theoretical and practical part. Theoretical part defines the concepts of decision making, multi-criteria decision making and its methods using specialized literature. It also defines the concept of insurance and its specifics relating to accident insurance. The practical part focuses on the specific solution of the given problem. The first step was a survey of offers of insurance companies operating on the Czech market that have separate accident insurance in their product portfolio. Based on these offers, decision variants have been created. The second step was to determine the five criteria on whose basis the variants were evaluated. After the general procedure has been established, the model has been applied. The proposed procedure was tried on a group of respondents to select the best offer for them. The target group, for which the procedure was designed, was set for people between the ages of 40 and 50 who do not have a risky job and do not engage in any hazardous leisure activities. Their preferences were determined by a questionnaire, based on which the decision matrices and weightings of the individual criteria were compiled. The optimal option was recommended to respondents.

Métodos de análise de decisão multicritério para a seleção de recursos em ambientes loT / Multicriteria decision analysis techniques for resources selection in IoT environments

Nunes, Luiz Henrique 12 December 2018 (has links)
A Internet das coisas é constituída de objetos que possuem pequenos sensores e atuadores capazes de interagir com o ambiente. Tais objetos ou coisas estão interconectados entre si e com acesso à Internet por meio de redes com e sem fio. A combinação entre os dispositivos embarcados com sensores e o acesso à Internet possibilita a comunicação dos recursos do mundo físico com o espaço cibernético, desempenhando um papel fundamental na resolução de muitos desafios encontrados na sociedade atual. Porém, a maioria das aplicações existentes são dedicadas a resolver problemas específicos utilizando tais recursos apenas em redes internas, limitando a real capacidade da Internet das Coisas. Diversos trabalhos na literatura propõem a reutilização de tais recursos em forma de serviço por meio de modelos como Dados como Serviço e Sensoriamento como Serviço. Neste contexto, em que potencialmente milhares de recursos podem transferir dados semelhantes de aplicações diferentes, a utilização de técnicas que possam selecionar recursos de forma sensível a contexto torna-se imprescindível. Nesta tese são propostos um conjunto de métodos para melhorar a relação custo-benefício na seleção de recursos em ambientes IoT, auxiliando na tomada de decisão durante a seleção dos recursos que serão ofertados como serviço. Os resultados obtidos por meio de estudos de caso, permitiram a comparação da qualidade da solução e do custo computacional das técnicas aplicadas na seleção de recursos em ambientes IoT, bem como o desenvolvimento de duas novas técnicas para a seleção de recursos, denominadas Elimination Sort e Fast Elimination Sort. / The Internet of Things is composed of objects which have small sensors and actuators capable of interacting with the environment. Such objects or things are interconnected with each other and has access to the Internet through wired and wireless networks. The combination of embedded devices with sensors and access to the Internet become it possible to communicate the resources of the physical world with the cyberspace, playing a key role in solving many challenges found in todays society. However, most existing applications solves a specific problem using its resources just for own purpose, limiting the actual ability of the Internet of Things. Several works propose the reuse of such resources through service models such as Data as Service and Sensing as a Service. In this context, where thousands of resources can transfer similar data from different applications, the use of techniques that can select these features in a context-sensitive way becomes essential. In this thesis, a set of methods to improve the cost-benefit of the process of selection of resources in IoT environments is proposed to support the decision making during resource selection that will be offered as a service. The results obtained through a case study allowed the comparison of the solution quality and the computational cost of the techniques applied for resource selection in IoT environments, as well as the development of two new techniques for the selection of resources called Elimination Sort and Fast Elimination Sort.

Análise multicritério de perspectivas do balanced scorecard para implantação em instituições de ensino superior /

Costa Junior, Haroldo. January 2018 (has links)
Orientador: Valério Antonio Pamplona Salomon / Banca: Claudemir Leif Tramarico / Banca: Claudio Luis Piratelli / Resumo: A implantação do Balanced Scorecard (BSC) pode criar um diferencial competitivo em Instituição de Ensino Superior (IES). O estudo presente tem por objetivo a utilização de análise multicritério para realização de priorização das perspectivas do BSC em três instituições de ensino superior, administradas pela mesma Mantenedora. Levando-se em consideração que o BSC não possui medição de suas perspectivas em escala de importância, fato esse que pode atrapalhar os gestores durante a implantação, nesse trabalho é possível verificar a utilização do método AHP (Analytic Hierarchy Process), na tomada de decisões com múltiplos critérios, o que permitiu a realização da priorização de perspectivas do BSC em cada uma das IES. Assim, as Instituições de Ensino poderão realizar a implantação do BSC de acordo com o grau de importância das perspectivas na visão de seus Diretores. Por meio dessa pesquisa, foi possível realizar uma análise com a utilização de duas importantes ferramentas: o BSC e o AHP na gestão das Instituições, o que permiti aos Diretores uma melhor condição na preparação e melhor monitoramento dos indicadores estratégicos. / Abstract: The Balanced Scorecard (BSC) deployment can create a competitive differential in Higher Education Institution (HEI). The purpose of this study is to use a multicriteria analysis to prioritize the perspectives of BSC in three higher education institutions, managed by the same maintainer. Considering that the BSC does not have a measurement of its perspectives in scale of importance, which can hinder managers during implantation, in this work it is possible to verify the use of the AHP (Analytic Hierarchy Process) method of making decision with multiple criteria, which allowed the achievement of the prioritization of BSC perspectives in each HEI. Thus, the Educational Institutions may carry out the implementation of the BSC according to the degree of importance of the perspectives in the vision of its Principals. Through this research, it was possible to carry out an analysis with the use of two important tools: the BSC and the AHP in the management of the Institutions, which will allow the Principals a better condition in the preparation and better monitoring of the indicators strategic. / Mestre

An Assessment Model for Energy Efficiency Program Planning in Electric Utilities: Case of the Pacific of Northwest U.S.A.

Iskin, Ibrahim 02 June 2014 (has links)
Energy efficiency stands out with its potential to address a number of challenges that today's electric utilities face, including increasing and changing electricity demand, shrinking operating capacity, and decreasing system reliability and flexibility. Being the least cost and least risky alternative, the share of energy efficiency programs in utilities' energy portfolios has been on the rise since the 1980s, and their increasing importance is expected to continue in the future. Despite holding great promise, the ability to determine and invest in only the most promising program alternatives plays a key role in the successful use of energy efficiency as a utility-wide resource. This issue becomes even more significant considering the availability of a vast number of potential energy efficiency programs, the rapidly changing business environment, and the existence of multiple stakeholders. This dissertation introduces hierarchical decision modeling as the framework for energy efficiency program planning in electric utilities. The model focuses on the assessment of emerging energy efficiency programs and proposes to bridge the gap between technology screening and cost/benefit evaluation practices. This approach is expected to identify emerging technology alternatives which have the highest potential to pass cost/benefit ratio testing procedures and contribute to the effectiveness of decision practices in energy efficiency program planning. The model also incorporates rank order analysis and sensitivity analysis for testing the robustness of results from different stakeholder perspectives and future uncertainties in an attempt to enable more informed decision-making practices. The model was applied to the case of 13 high priority emerging energy efficiency program alternatives identified in the Pacific Northwest, U.S.A. The results of this study reveal that energy savings potential is the most important program management consideration in selecting emerging energy efficiency programs. Market dissemination potential and program development and implementation potential are the second and third most important, whereas ancillary benefits potential is the least important program management consideration. The results imply that program value considerations, comprised of energy savings potential and ancillary benefits potential; and program feasibility considerations, comprised of program development and implementation potential and market dissemination potential, have almost equal impacts on assessment of emerging energy efficiency programs. Considering the overwhelming number of value-focused studies and the few feasibility-focused studies in the literature, this finding clearly shows that feasibility-focused studies are greatly understudied. The hierarchical decision model developed in this dissertation is generalizable. Thus, other utilities or power systems can adopt the research steps employed in this study as guidelines and conduct similar assessment studies on emerging energy efficiency programs of their interest.
