Thesis (MScEng)-- Stellenbosch University, 2013. / ENGLISH ABSTRACT: It has been postulated that lean thinking principles can be successfully applied to any industry. Following on that postulation, there have been great advances in the area of lean thinking outside the “traditional” domain of manufacturing. One such advancement has been in the area of maintenance operations where lean thinking has been used through the concept of lean maintenance. However, a problem lies in the fact that the work that has been done so far has been largely limited to the manufacturing environment where lean maintenance is practised as a prerequisite for lean manufacturing. Little evidence exists of the use of frameworks or models that can test, let alone apply, lean thinking in operational maintenance environments outside of the manufacturing context. The main objective of this research was to come up with a framework, based on lean thinking tools and relevant performance measures, which will prove the applicability or otherwise, of lean thinking in an operational maintenance environment outside the traditional domain of manufacturing. A case study of the rolling stock section of the Salt River depot of PRASA, Metrorail, which is a typical non-traditional domain for lean thinking, was used to build and verify the framework. The Analytic Hierarchy Process (AHP) together with the Quality Function Deployment (QFD) process, is used in building and quantifying the judgements made in developing elements of the framework. The Value Stream Management process is used to predict the possible outcomes of using the proposed framework in the case study. The study was based on the hypothesis that lean thinking can also be applicable to non-manufacturing oriented maintenance organisations. The ensuing framework is used to make the argument for the use of the lean thinking approach in non-manufacturing oriented maintenance environments and hence expand the body of knowledge in this subject area. It also provides a roadmap for PRASA, Metrorail and other similar maintenance organisations in the rail industry to streamline and improve current operations through value addition and waste elimination efforts. / AFRIKAANSE OPSOMMING: Daar word bespiegel dat die beginsels van besparende denke (“lean thinking”) suksesvol toegepas kan word op enige industrie. As gevolg van hierdie hipotese is daar groot vooruitgang op die gebied van besparende denke buite die “tradisionele” gebied van vervaardiging. Een sodanige vooruitgang is op die gebied van die verrigting van instandhouding waar besparende denke bekend is as die konsep van “lean maintenance”. Die problem is dat die vooruitgang tot dusver beperk is tot die vervaardigingsomgewing waar besparende instandhouding beskou word as ‟n vereisde vir besparende vervaardiging. Daar word min gebruik gemaak van raamwerke of modelle om besparende denke te toets of om dit toe te pas in instandhoudingsomgewings buite die vervaardigingskonteks. Die hoofdoelwit van hierdie navorsing is om te vore te kom wet ‟n raamwerk wat gegrond is op besparende denke en relevante prestasie maatstawwe, en wat die toepaslikheid van besparende denke , al dan nie, op die verrigting van instandhouding buite die tradisionele gebied van vervaardiging sal bewys. ‟n Gevalle studie van die Soutrivier Depot van PRASA Metrorail, wat tipies is van ‟n nie-tradisionele gebied vir besparende denke, is gebruik vir die bou en stawing van die raamwerk. Die analitiese hiëragiese proses (AHP) tesame met die kwaliteits funksionele ontplooiing (QFD) proses word gebruik in die kies van elemente vir die raamwerk. Die waarde stroom bestuursproses word gebruik om die moontlik uitkomste van die gebruik van die voorgestelde raamwerk, te voorspel. Die studie is gegrond op die hipotese dat besparende denke ook toegepas kan word op nie-vervaarding-georienteerde instandhoudingsorganisasies. Die raamwerk word gebruik om te bewys dat die besparende denke benadering gebruik kan word in nie-vervaardiging–georienteerde instandhoudingsomgewings en dus kennis hieroor uit te brei. Die raamwerk kan ook gebruik word as ‟n padkaart deur Metrorail en ander soortgelyke instandhoudingsorganisasies in die spoorweg industrie, om hulle huidige werksverrigting deur waarde toevoeging te verbeter en om verkwisting te voorkom.

Les applications logicielles sont de plus en plus diversifié et complexe. Avec le développement orageux du Cloud Computing et de ses applications, les applications logicielles deviennent encore plus complexes que jamais. Les applications de cloud computing complexes peuvent contenir un grand nombre de composants logiciels qui nécessitent et consomment une grande quantité de ressources (matériel ou d'autres composants logiciels) répartis en plusieurs niveaux en fonction de la granularité de ces ressources. En outre, ces composants logiciels peuvent être situés sur différents nuages. Les composants logiciels et de leurs ressources requises d'une application Nuage ont des relations complexes dont certains pourraient être résolus au moment de la conception, mais certains sont nécessaires pour faire face au moment de l'exécution. La complexité des logiciels et de l'hétérogénéité de l'environnement Couverture devenir défis que les solutions d'élasticité actuelles ont besoin de trouver des réponses appropriées à résoudre. L'élasticité est l'un des avantages du cloud computing, qui est la capacité d'un système Cloud pour adapter à la charge de travail des changements par des ressources d'approvisionnement et deprovisioning d'une manière autonome. Par conséquent, les ressources disponibles correspondent à la demande actuelle d'aussi près que possible à chaque moment. Pour avoir une solution d'élasticité efficace, qui ne reflète pas seulement la complexité des applications Cloud mais également à déployer et à gérer eux d'une manière autonome, nous proposons une approche d'élasticité roman. Il est appelé à plusieurs niveaux élasticité fine qui comprend deux aspects de la complexité de l'application: plusieurs composants logiciels et la granularité des ressources. Le multi-niveau élasticité fine concerne les objets touchés par les actions d'élasticité et la granularité de ces actions. Dans cette thèse, nous introduisons plateforme Roboconf un système de cloud computing autonome (ACCS) pour installer et reconfigurer les applications complexes ainsi que soutenir le multi-niveau élasticité fine. A cet effet, Roboconf est également un gestionnaire d'élasticité autonome. Merci à cette plate-forme, nous pouvons abstraire les applications cloud complexes et automatiser leur installation et de reconfiguration qui peut être de plusieurs centaines d'heures de travail. Nous utilisons également Roboconf à mettre en œuvre les algorithmes de multi-niveau élasticité fine sur ces applications. Les expériences menées indiquent non seulement l'efficacité de l'élasticité fine multi-niveau, mais aussi de valider les caractéristiques de support de cette approche de la plateforme Roboconf. / Software applications are becoming more diverse and complex. With the stormy development of Cloud Computing and its applications, software applications become even more complex than ever. The complex Cloud applications may contain a lot of software components that require and consume a large amount of resources (hardware or other software components) distributed into multiple levels based on granularity of these resources. Moreover these software components might be located on different clouds. The software components and their required resources of a Cloud application have complex relationships which some could be resolved at design time but some are required to tackle at run time. The complexity of software and heterogeneity of Cloud environment become challenges that current elasticity solutions need to find appropriate answers to resolve. Elasticity is one of benefits of Cloud computing, which is capability of a Cloud system to adapt to workload changes by provisioning and deprovisioning resources in an autonomic manner. Hence, the available resources fit the current demand as closely as possible at each point in time. To have an efficient elasticity solution which not only reflects the complexity of Cloud applications but also deploy and manage them in an autonomic manner, we propose a novel elasticity approach. It is called multi-level fine-grained elasticity which includes two aspects of application’s complexity: multiple software components and the granularity of resources. The multi-level fine-grained elasticity concerns objects impacted by elasticity actions and granularity of these actions. In this thesis, we introduce Roboconf platform an autonomic Cloud computing system (ACCS) to install and reconfigure the complex applications as well as support the multi-level fine-grained elasticity. To this end, Roboconf is also an autonomic elasticity manager. Thanks to this platform, we can abstract the complex Cloud applications and automate their installation and reconfiguration that can be up to several hundred hours of labour. We also use Roboconf to implement the algorithms of multi-level fine-grained elasticity on these applications. The conducted experiments not only indicate efficiency of the multi-level fine-grained elasticity but also validate features supporting this approach of Roboconf platform.

It specificaly discusses the quantification of product competitiveness and proposes the optimization of product design characteristics as a function of product competitiveness. A topological modeI to represent the development of competitive products is proposed .It contains the following phases: (1) competitive strategy for product development, (2) definition of the customer, (3) planning of competitive products, (4) quality and value deployment, (5) competitive assessment of the product , (6) adjustments in the product design. The integration of these phases on a quantitative basis, with emphasis on phases (3) and (4), constitute the main original contribution of this thesis. A methodology for the development of competitive products is introduced, as an example. It quantifies the product competitiveness in terms of the variables 'perceived quality' and 'perceived price'. These variables are then used to optimize the technical characteristics of the product by means of the Quality Function Deployment (QFD) methodology. Finally, these variables are also used to indicate the necessity of adjustments in the product design. In this way, the several phases of product development are integrated in terms of the same variables. The proposed model is applied to two published examples of product development and two new case studies, as a theoretical reference for the planning, design and competitive assessment of the products analyzed. In each category, one manufactured product and one service are studied. / Esta tese investiga o desenvolvimento de produtos competitivos, sejam eles tangíveis (bens) ou intangíveis (serviços). Especificamente, ela discute a conceituação da competitividade do produto e propõe a otimização dos parâmetros de projeto do produto em função da competitividade. Um modelo topológico para representar o desenvolvimento de produtos competitivos é proposto. Ele contém os seguintes módulos: (1) estratégia competitiva para o produto, (2) definição do cliente, (3) planejamento da competitividade do produto, (4) desdobramentos da qualidade e do valor, (5) avaliação da competitividade do produto e (6) ajustes no projeto do produto. A integração destes módulos em bases quantitativas, com ênfase nos módulos (3) e (4), é a principal contribuição original do trabalho. Com o intuito de ilustrar a utilização do modelo, é apresentada uma metodologia para o desenvolvimento do produto. Esta define a competitividade do produto em função das variáveis 'qualidade percebida' e 'preço percebido' - empregadas aqui para representar o valor do produto para o cliente. Estas variáveis são posteriormente utilizadas para otimizar as características técnicas do produto e os parâmetros do processo, ao longo do ciclo do desenvolvimento do produto; para isto, adota-se a metodologia QFD. Finalmente, estas variáveis são também empregadas para avaliar a competitividade do produto e indicar a necessidade de ajustes no projeto. Desta forma, as diversas fases do desenvolvimento do produto são integradas em função das mesmas variáveis. O modelo proposto é aplicado em exemplos conhecidos e em estudos de caso inéditos. Em cada modalidade, são considerados um produto tangível e um produto intangível. Nestas aplicações, o modelo é utilizado como uma referência conceitual para o planejamento, o projeto e a avaliação da competitividade dos produtos analisados.

Uma dessas unidades de ensino de IF localiza-se na cidade de Passos (MG), cujo processo de implantação foi conduzido primordialmente por atores pertencentes ao próprio instituto, integrantes da burocracia pública. Esses atores ocupavam cargos comissionados próprios das Instituições Federais de Ensino (IFEs) que em correlação/equiparação com os Cargos de Direção e Assessoramento Superior (DAS) foram enquadrados como integrantes da burocracia de alto escalão do governo federal. No entanto, à medida que empiricamente se observa a atuação desses atores percebe-se que ela está bem mais relacionada ao papel desempenhado pela burocracia de médio escalão. Cavalcante e Lotta (2015, p. 13) afirmam que os Burocratas de Médio Escalão (BMEs) são atores relevantes no processo de implementação de políticas públicas e a importância dessa burocracia está justamente em ser o elo entre o alto escalão e os executores das políticas públicas. Ao estudar a política pública de educação profissional parte-se do pressuposto de que, embora sejam materializadas através dos governos, as políticas públicas envolvem vários atores e níveis de decisão (SOUZA, 2006), advertindo sobre o aspecto deliberativo e muitas vezes discricionário do processo de produção de políticas públicas. Nesse sentido, para melhor compreender a política pública de educação profissional, a criação dos institutos federais e a atuação dos atores envolvidos no processo de implantação do campus de IF na cidade de Passos (MG), este trabalho pautou-se em uma revisão de literatura sobre os temas: educação profissional; criação e expansão da rede federal de educação profissional; conceitos, enfoques e implementação de políticas públicas; e burocracia pública, com foco na burocracia de nível intermediário. Pautou-se também na realização e análise de entrevistas com três atores-chave do processo de implantação do campus do Instituto Federal de Educação, Ciência e Tecnologia do Sul de Minas Gerais em Passos (MG). Este trabalho também procura se valer dos enfoques de Avaliação de Políticas Públicas (EAv) e de Análise e Políticas Públicas (EAn), que tratam da dimensão programas sob diferentes perspectivas. Para o EAv a implantação do campus do IF atendeu às dimensões estabelecidas pelo Plano de Expansão da Rede. E com o EAn considera-se que o plano materializou a política (policy) através de seus processos políticos (politics) e instituições políticas (polity). Por fim, os atores envolvidos na implantação do campus do instituto federal em foco foram fundamentais para esse processo, sendo denominados de burocratas de alto escalão, mas atuaram conforme o papel desempenhado pela burocracia de médio escalão. Sua atuação ocorreu principalmente na intermediação de ações da política, na aplicação das diretrizes da política e na coordenação de ações entre superiores e subordinados, ou seja, em aspectos que proporcionaram a implementação da política pública de educação profissional. / This work approaches the public policy of professional education which, through the Expansion Plan of the Federal Network of Professional Education Science and Technology, provided the creation of the Federal Institutes of education, science and technology (IFs) and the opening of new units of instruction in several regions of the country between the years of 2003 to 2014. One of these teaching units IF (Federal Institute) it is located in Passos (MG), whose deployment process was conducted primarily by actors belonging to the Institute, members of the public bureaucracy. These actors were commissioned positions of the federal institutions of education (IFEs) in parity with the positions and Superior advisory services (DAS) were included as members of the senior bureaucracy of the federal Government. However, as empirically observed these actors realizes that it is much more related to the function performed by the middle ranking bureaucracy. Cavalcante and Lotta (2015, p. 13) say that the middle ranking bureaucrats (BMEs) are relevant actors in the process of implementation of public policies and the importance of this bureaucracy is precisely to be the junction between the high-level and the executors of public policies. By studying public policy professional education the assumption that, although they are materialized through Governments, public policies involve several actors and levels of decision (SOUZA 2006), warning about the deliberative and often discretionary aspect of the production process of public policies. In this sense, to better understand the public policy of professional education, the creation of federal institutions and the performance of the actors involved in the implementation process of the campus of IF located in Passos (MG), this work was in a review of literature on the topics: professional education; creation and expansion of the professional education; concepts, approaches and implementation of public policies; and public bureaucracy, focusing on mid-level bureaucracy. Was also in the realization and analysis of interviews with three key actors of the deployment process of the campus - Federal Institute of education, science and technology in the South of Minas Gerais located in Passos (MG). This work also search to focus on the Evaluation of Public Policies (EAv) and Analysis and Public Policies (EAn), dealing with the dimension programs under different perspectives. For EAv implementation campus do IF met the dimensions established by the network expansion plan. And with the EAn the plan materialized to politics (policy) through their political processes (politics) and political institutions (polity). Finally, the actors involved in the implementation of the federal Institute's campus in focus were critical to this process, being named to high-level bureaucrats, but acted as the role played by mid-level bureaucracy. Its performance occurred mainly the intermediation of policy action, in the implementation of policy guidelines and coordination of actions between superiors and subordinates, on aspects that have provided the implementation of public policy professional education.

Precision Agriculture (PA) is an innovative technology that has proven to be an important management tool in a rural enterprise. This study aims to estimate the total amount of inputs such as limestone, phosphorus, potassium and sulfur in the implementation by the average rate and the variable rate, to compare the costs of buying these fertilizers for soybean plantation by the traditional method and the method of PA and relate them to the costs of implementing the PA. To analyze the costs of purchasing fertilizers we compared the technical recommendation based on the average of each field of application and variable application rate based on soil analysis extracted by a specialized company. It was saved $134.14/ha in the acquisition of inputs, in other words, 19.86% of the necessary amount if we use conventional farming. The implementation of PA practically pays itself in the first year, since the initial cost of precision agriculture is $135,00/ha, in a farm with planting area as the study. We can say that Precision Agriculture is a tool that can be used strategically in the management of rural enterprises, as it is a source of information that serves as basis for improving assertiveness of decisions in property management. / A Agricultura de Precisão (AP) é uma tecnologia inovadora que tem se mostrado como uma importante ferramenta de gestão de uma empresa rural. O objetivo deste trabalho foi estimar a quantidade total dos insumos Calcário, Fósforo, Potássio e Enxofre na aplicação pela média e na aplicação a taxa variável, comparar os custos de aquisição destes fertilizantes para plantio da cultura da soja pelo método tradicional e pelo método da AP, e relacioná-los com os custos de implantação da AP. Para analisar os custos de aquisição dos fertilizantes comparamos a recomendação técnica considerando a média de aplicação de cada talhão e a aplicação a taxa variada com base em análises de solos extraídas por uma empresa especializada. Na aquisição dos insumos tivemos uma economia de R$134.14/ha, ou seja, 19,86% do montante necessário se utilizarmos a agricultura convencional. A implantação da AP praticamente viabiliza-se no primeiro ano, já que o custo inicial da agricultura de precisão é de R$135,00/ha, numa fazenda com área de plantio como a da estudada. Podemos dizer que a Agricultura de Precisão é uma ferramenta que pode sim ser usada estrategicamente na gestão da empresa rural, pois é fonte de informações que servem de base para melhorar a assertividade das decisões tomadas na gerência da propriedade.

L'objectif de cette thèse est d'offrir une solution de bout en bout permettant de décrire et de déployer de façon fiable une application distribuée dans un environnement virtualisé. Ceci passe par la définition d'un formalisme permettant de décrirer une application ainsi que son environnement d'exécution, puis de fournir les outils capable d'interpéter ce formalisme pour déployer (installer, instancier et configurer) l'application sur une plate-forme de type cloud computing. / Cloud computing aims to cut down on the outlay and operational expenses involved in setting up and running applications. To do this, an application is split into a set of virtualized hardware and software resources. This virtualized application can be autonomously managed, making it responsive to the dynamic changes affecting its running environment. This is referred to as Application Life-cycle Management (ALM). In cloud computing, ALM is a growing but immature market, with many offers claiming to significantly improve productivity. However, all these solutions are faced with a major restriction: the duality between the level of autonomy they offer and the type of applications they can handle. To address this, this thesis focuses on managing the initial deployment of an application to demonstrate that the duality is artificial. The main contributions of this work are presented in a platform named VAMP (Virtual Applications Management Platform). VAMP can deploy any legacy application distributed in the cloud, in an autonomous, generic and reliable way. It consists of: • a component-based model to describe the elements making up an application and their projection on the running infrastructure, as well as the dependencies binding them in the applicative architecture; • an asynchronous, distributed and reliable protocol for self-configuration and self-activation of the application; • mechanisms ensuring the reliability of the VAMP system itself. Beyond implementing the solution, the most critical aspects of running VAMP have been formally verified using model checking tools. A validation step was also used to demonstrate the genericity of the proposal through various real-life implementations.
