Thesis (MEng)--Stellenbosch University, 2015. / ENGLISH ABSTRACT: In recent years, the management of physical assets has become increasingly important, even more so, in asset intensive organisations. This research work presents an overall approach to quantify reliability of rolling stock assets in the rail environment. The current maintenance management system in the case studied is over-reliant on cancellations and delays as reliability measure. The objectives of this study were, therefore, to develop a scientific approach to quantify the reliability of the rolling stock fleet and to develop a maintenance planning model based on system reliability. The research methodology followed made use of failure statistics, failure distributions and the interdependence of different systems to determine the impact of component failures on the overall system reliability. This could then be used to determine the reliability of individual train sets in order to better understand their performance. The reliability measure could be used for predicting component and train set failures as well as to better understand the contribution of maintenance towards reliability, hence the term Reliability Based Maintenance. The model, validated with real data, illustrates how the reliability measure can be used to determine maintenance intervals of different train sets. Based on the results, recommendations are made in relation to future planning of the maintenance strategy. / AFRIKAANSE OPSOMMING: Die bestuur van fisiese bates het in die afgelope tyd meer belangrik geword, veral in organisasies wat afhanklik is van hulle fisiese bates. Hierdie navorsing stel ‘n metode voor wat die betroubaarheid van rollende materiaal bates in die spoor bedryf kwantifiseer deur gebruik te maak van falingstatistiek. In die huidige instandhouding bestuurstelsel van die gevallestudie word daar te veel gesteun op kansellasies en vertragings van treine as ‘n betroubaarheids meting. Daarom was die doelwitte van die navorsing om ‘n wetenskaplike benadering te ontwikkel om betroubaarheid van rollende materiaal the kwantifiseer, en om ‘n instandhouding beplannings model voor te stel, gebaseer op sisteem betroubaarheid. Die navorsingsmetodologie is gebaseer op falingstatistieke, falingverspreidings, en die interafhanklikheid van stelsels word gebruik om die invloed van komponent falings op die betroubaarheid van die totale stelsel te bepaal. Hierdie benadering word dan gebruik om die betroubaarheid van individuele treinstelle en die werksverrigting van individuele trainstelle te bepaal. Hierdie instandhouding meting kan gebruik word om falings van komponente en treinstelle te voorspel, asook om die bydrae van instandhouding tot betroubaarheid beter te verstaan, daarom genoem Betroubaarheids Gebaseerde Instandhouding. Dit is ook geïllustreer hoe die betroubaarheid meting gebruik kan word om instandhouding intervalle te bepaal. Die betroubaarheid model is met werklike data gevalideer en aanbevelings word gemaak hoe om betroubaarheid te gebruik om die toekomstige beplanning van instandhouding te doen.

As particularidades desta tipologia de patrimônio vêm permitindo múltiplas possibilidades da sua transformação em equipamentos culturais, como museus, centros de documentação e espaços de cultura e de turismo que são viabilizados ou incentivados por meio das políticas públicas de preservação implementadas pela União, estados e municípios. No campo acadêmico verifica-se um reduzido número de trabalhos que investigam as particularidades, práticas, métodos e até mesmo resultados relacionados às políticas públicas que atuam na preservação ferroviária. É diante desse contexto que este trabalho busca caracterizar as práticas das políticas públicas no estado de São Paulo, mais especificamente da cidade de Bauru, tendo como objetos o Conselho de Defesa do Patrimônio Cultural e o Museu Ferroviário Regional. Esses mecanismos de proteção estão presentes em muitos municípios e se tornaram a principal ferramenta de preservação de bens ferroviários. Em termos metodológicos, o trabalho contará com pesquisa bibliográfica exploratória sobre o tema, análise documental e entrevistas com agentes envolvidos no processo. Como resultado, pretende-se chegar à compreensão das diretrizes, conceitos, valores e agentes que atuam na preservação por meio das políticas públicas, indicando-nos o possível método de musealização como prática principal quando se trata do patrimônio industrial ferroviário, não só na cidade de Bauru como também em outros municípios do estado de São Paulo. / The issues related to the preservation of railway heritage in Brazil is getting more and more importance in last decades, not only due to the technological obsolescence, but mainly due to privatization process of the companies in the sector. The characteristics of that kind of heritage have allowed many possibilities in its transformation in cultural equipment, such as museums, document center and cultural and tourism spaces that are encouraged by the country, states and cities. There are a few works in academic field that investigate the particularities, practices, methods and even results related to the public policies that act in railway preservation. In this context, this work aims to characterize public policies practices in São Paulo state, more specifically at Bauru city, having as the research object the Council of Defense of Cultural Heritage and the Regional Railway Museum. These protection mechanisms are presents in many municipalities and they became the main tool for the preservation of railway goods. In methodological terms, the research will have exploratory bibliographic research, documentary analysis and interviews with agents related in the process. As a result, we intend to comprehend the guidelines, concepts, values and agents that act in the preservation through public policies, indicating us the possible method of musealization as main practice for the industrial railway heritage, not only in Bauru city, but also in other municipalities in São Paulo State
