Este presente trabalho visa avaliar a aplicação da metodologia Design for Six Sigma (DFSS) ao processo de desenvolvimento de veículos (PDV) visando atingir níveis de qualidade Seis Sigma quando do início do processo de fabricação. Na verdade, quando se fala em fabricar produtos que já nasçam com níveis de qualidade Seis Sigma, não significa que seja mandatório que se obtenha a honrosa relação de 3,4 defeitos por milhão de oportunidades, mas sim que proporcionem resultados positivos em relação à melhoria da qualidade, otimização de custos, redução do tempo de desenvolvimento, vislumbrando o mais importante de todos os aspectos: o total entusiasmo do cliente. Para tanto, quando se fala da aplicação do DFSS no âmbito do desenvolvimento de veículos, o panorama deste contexto torna-se relativamente mais amplo e complexo, face ao nível de desenvolvimento tecnológico deste setor. O assunto é introduzido descrevendo-se o processo de desenvolvimento de veículos em sua abordagem atualmente difundida, alicerçada por um processo bem definido e estruturado, para se poder introduzir o DFSS neste processo. Antes, porém, introduz-se toda a metodologia referente ao Seis Sigma, por ser o fundamento base para a criação do DFSS. Por fim, a colocação de um estudo de caso procura relatar a aplicação da metodologia DFSS aplicada especificamente para a GM, procurando relatar a estratégia da aplicação, bem como seus principais ganhos alcançados. / This present work aims to evaluate the application of the Design for Six Sigma (DFSS) methodology to the vehicle development process (VDP) seeking to reach Six Sigma quality levels when the beginning of the production process. Actually, when it is spoken in manufacturing products that are already born with Six Sigma quality levels, it doesn\'t mean that it is mandatory that must be obtained the honorable relationship of 3,4 defects per millions of opportunities, but that provide positive results in relation to the quality improvement, costs optimization, reduction of the development timing, glimpsing the most important of all of the aspects: the customer\'s total enthusiasm. For that, when it is spoken about the application of DFSS in the extent of the vehicles development, the scenery of this context becomes relatively wider and complex, face at the level of technological development of this section. The subject is introduced being described the vehicles development process in its approach currently spread, found by a very defined and structured process, to allow introducing DFSS in this process. Before, however, the whole methodology regarding Six Sigma is introduced, for being the foundation base for the creation of DFSS. Finally, the placement of a case study tries to demonstrate the application of the DFSS methodology applied specifically for GM, trying to report the strategy of the application, as well as their main reached benefits.

Memoria para optar al título de Ingeniero en Alimentos / El chocolate es considerado uno de los productos más importantes dentro del negocio de confitería. Las pérdidas de materias primas durante el 2008 en la fábrica de chocolates alcanzaron los $ 784 millones de pesos y el 25% se concentró en la etapa de fabricación de chocolates. Se utilizó la metodología DMAIC (Definir, medir, analizar, implementar y controlar) para reducir las pérdidas y mejorar los procesos involucrados en las etapas de fabricación de chocolate, a nivel de ingeniería, producción y calidad. Siguiendo la metodología DMAIC se creó un equipo multidisciplinario de trabajo. Se identificaron las causas potenciales de pérdidas en cada etapa del proceso de fabricación, se priorizaron y se asignaron responsables para su implementación. La capacidad del proceso se midió mediante el uso de herramientas estadísticas, obteniendo un sigma inicial de 1,83, y luego de implementar las mejoras el sigma final fue de 3,87. Se crearon planillas para mantener bajo control las mejoras implementadas. Con el uso de la metodología DMAIC implementada, las pérdidas disminuyeron en el proceso de 207,6 kg por día promedio, a 137,3 kg por día promedio, esto significará un ahorro de $ 22 millones de pesos anuales. / The chocolate is considered one of the most important products in the confectionery business. The raw material losses during 2008 in the Manufacture chocolate business reached $ 784 million (chilean pesos) and 25% was focused on the stage of manufacture chocolate. It was used the DMAIC (Define, measure, analyze, implement and control) methodology to reduce losses and improve the processes involved in the stages of chocolate manufacture at the level of engineering, production and quality. Following the DMAIC methodology was created by a multidisciplinary team work. The potential causes of losses was identified at each stage of the manufacturing process, and assigned responsibility people was prioritized for its implementation. The process capability was measured by using statistical tools, obtaining an initial sigma of 1,83, and then implement the improvements was the final sigma 3,87. Spreadsheet were created to keep control of the improvements implemented. Using the DMAIC methodology implemented, the losses in the process decreased from 207,6 kg per day average to 137,3 kg per day average, this will mean was saving of $ 22 million (chilean pesos) per year.

Economic development in any country or area depends heavily on the performance of the construction industry. This is because the subsequent development of infrastructure increases economic activity, living standards, direct foreign investments, and business opportunities. The construction industry in Pakistan also plays a significant role in its economic activity, and the government’s focus towards increasing infrastructure development provides the construction industry with growth prospects. It is observed that quality management practices in the Pakistan construction industry are highly inadequate to enhance quality. The construction industry there is highly challenged with inadequate delays in projects and project quality. The need for the implementation of Six Sigma in the construction industry in Pakistan is underestimated. The structured questionnaire has been developed to collect data from a sample size of 100 managers from 100 construction companies in Pakistan. Current study determines the current trends, the extent of implementation, prior knowledge and related training required in the implementation of Six Sigma.

D.Phil. (Engineering Management) / Process improvement is essential for an organisation to remain competitive in the global market. Regardless of the type of products or service being rendered, such improvement is essential for remaining profitable and staying at the top of one’s industry market. The Lean Six Sigma (LSS) methodology is a preferred methodology for continuously improving business processes, thereby improving profitability and increasing market share. Higher education institutions are increasingly being placed under pressure to improve throughput and to ensure that that their institutions are sustainable. This focus on higher education inefficiencies has resulted in institutions looking for new ways to improve processes which will lead to increases in throughput. In this study, a LSS framework has been developed and applied for improving engineering education processes...

This diploma thesis has been created based on the demand of the management of DHL Exel Supply Chain and Swindon Pressings Limited to increase the efficiency and utilization of resources employed within they operations. The theoretical introduction part is first of dealing with the terms "logistics" and "supply chain management" in the perspective of their use in the contemporary logistics theory, comparison of their meaning (are there differences) and explanation of their use in this thesis. Subsequently I am explaining "reverse logistic" and its position in the structures of corporations and logistics itself. Supply chain management and the concept of lean manufacturing combined with the six sigma approach are, from my point of view, essential for today's supplier-customer relationships. That is why those topics are examined in the last part of the theoretical chapter. Returnable packaging and the transport process are key elements of the second part -- practical part, the reengineering of logistics processes which occurred at Swindon Pressings Limited. The aim of this thesis is to analyze the give problem, develop problem solving options and critically comment them. Finally choose one of the options, implement it and document the process of "going live".
