Texte intégralAtt utforska enorma mängder användargenererad data med ämnen postulerar ett nytt sätt att hitta användbar information. Ämnena antas vara “gömda” och måste “avtäckas” med statistiska metoder såsom ämnesmodellering. Dock är användargenererad data generellt sätt kort och stökig t.ex. informella chattkonversationer, mycket slangord och “brus” som kan vara URL:er eller andra former av pseudo-text. Denna typ av data är svår att bearbeta för de flesta algoritmer i naturligt språk, inklusive ämnesmodellering. Det här arbetet har försökt hitta den metod som objektivt ger dem bättre ämnena ur kort och stökig text i en jämförande studie. De metoder som jämfördes var latent Dirichlet allocation (LDA), Re-organized LDA (RO-LDA), Gaussian Mixture Model (GMM) with distributed representation of words samt en egen metod med namnet Neural Probabilistic Topic Modeling (NPTM) baserat på tidigare arbeten. Den slutsats som kan dras är att NPTM har en tendens att ge bättre ämnen på kort och stökig text jämfört med LDA och RO-LDA. GMM lyckades inte ge några meningsfulla resultat alls. Resultaten är mindre bevisande eftersom NPTM har problem med långa körtider vilket innebär att tillräckligt många stickprov inte kunde erhållas för ett statistiskt test.

Texte intégralNum mercado competitivo como o atual, as empresas são forçadas a estabelecer métodos mais eficazes para gerirem os seus stocks uma vez que a gestão dos mesmos é um dos processos mais importantes para o sucesso das organizações. Uma das mais valias deste processo é a diminuição do nível de stock que por sua vez tem um impacto positivo no desempenho organizacional e na redução dos custos totais das empresas. O objetivo deste estudo é analisar e otimizar a gestão de stocks de uma Estação de Serviço da Repsol Portuguesa de forma a minimizar os seus custos anuais de stock. A Repsol é uma empresa multienergética internacional nascida em Espanha e com presença notória em Portugal desde 1990. Este relatório de dissertação pretende ser uma contribuição prática para encontrar o equilíbrio entre a compra e a procura dos produtos vendidos numa Estação de Serviço da Repsol Portuguesa e permitir, deste modo, uma melhor tomada de decisão. Neste estudo serão analisados os modelos de controlo e classificação de stocks e posteriormente aplicado o modelo da Quantidade Económica de Encomenda (QEE). O modelo da QEE define qual a quantidade ótima de encomenda, de forma a minimizar os custos associados ao stock. No final do estudo, é alcançada uma otimização da gestão de stocks, ou seja, existe a possibilidade de redução do custo total do stock em 39,69% com base nos modelos académicos aplicados.
In a competitive market as the current one, companies are forced to establish more efficient methods to manage their stocks, since stock management is one of the most important processes for the success of organizations. One of the advantages of this process is the reduction in the stock level which in turn has a positive impact on organizational performance and on the reduction of the companies’ total cost. The purpose of this study is to analyze and optimize the stock management of a Repsol Portuguesa Gas Station to minimize its annual stock costs. Repsol is an international multi-energy company born in Spain with a notable presence in Portugal since 1990. This dissertation report aims to be a practical contribution by finding the balance between the purchase and the demand for the products sold at one Repsol Portuguesa Gas Station thus allowing better decision making. In this study the stock control and classification models will be analyzed and then the Economic Order Quantity (QEE) model will be applied. The QEE model defines the optimal order quantity that should be ordered to minimize the costs associated with stock. At the end of the study, an optimization of stock management is achieved, meaning that there is a possibility of reducing the stock total cost by 39,69% based on the applied academic models.

As perdas trabalhistas nas Instituições Financeiras representam um valor considerável que devem ser consideradas no modelo de capital regulatório para risco operacional, segundo Basileia. A presente dissertação demonstra uma forma de mensurar o risco às quais as Instituições Financeiras estão expostas nesse tipo de perdas. Diversos tipos de distribuições são analisados conforme sua aderência tanto na frequência como na severidade das perdas. Para os valores de frequência, foi obtida uma amostra de dados real, enquanto para a severidade foram utilizados valores obtidos de relatórios de instituto de pesquisa que serviram de insumo para os cálculos de ações trabalhistas conforme legislação brasileira vigente na CLT (Consolidação das Leis do Trabalho).
According to Basel, the labor losses in Financial Institutions represent a substantial value that should be regarded in the model of regulatory capital for operational risk. This dissertation demonstrates a way to measure the risk to which Financial Institutions are exposed to in this type of loss. Several types of distributions are analyzed according to their adherence both in frequency and severity of losses. For frequency values, it was obtained a sample of actual data, whilst for the severity were used values given from reports of research institute which served as an input for the calculations of labor actions according to the present Brazilian legislation in CLT (Consolidation of Labor Laws).
