Além dos recursos financeiros em si, as empresas também investem tempo e esforços para atingir desempenhos semelhantes às mais competitivas, as quais julgam ser o “benchmarking”, ou seja, a referência em seus negócios. Entretanto, buscar somente se espelhar nas melhores práticas das empresas de referência não possibilita tornar-se líder no negócio, pois para tanto seriam necessários outros ingredientes, outras estratégias que façam a diferença. Quando direcionado o foco para o produto em si, no caso deste estudo em específico da indústria automobilística que é um segmento bastante competitivo no mundo, faz-se necessário estratégias muito mais sofisticadas ou muitas vezes ainda inexistentes. Mencionado por diversos líderes e executivos de grandes empresas multinacionais como uma metodologia eficaz, o Design for Six Sigma, ou simplesmente DFSS, possibilita aprofundamentos e desdobramentos muito importantes para o entendimento dos mercados, de seus clientes, das suas necessidades e anseios. Pela flexibilidade do uso da metodologia do DFSS, torna-se possível desenvolver propostas e soluções para um dos diferenciais mais importantes neste mercado competitivo, a inovação. Em função da subjetividade presente sob alguns aspectos do conceito deste diferencial, propôs-se adotar a lógica fuzzy para se trabalhar com as variáveis mais importantes de natureza linguística e, combinado à relação sinal ruído de Taguchi, mensurar de forma quantitativa o grau de inovação inerentes aos produtos. Com este modelamento, validado por meio da análise de diversos sistemas veiculares que evoluíram ao longo da história automobilística, torna-se possível comparar produtos correntes com novas ideias e propostas do ponto de vista da inovação, fornecendo assim subsídios úteis para o processo de tomada de decisão / To pursue the competitiveness, many companies end up adopting similar strategies based on the most common and disseminated practices in their respective business. Beyond the financial resources, the companies also invest time and efforts in order to achieve similar performances of the most competitive ones which they deem to be "benchmarking", i.e. the reference in your business. However, simply adopting the best practices of those reference companies will not allow become a leader in their businesses, since it would require other ingredients, other strategies that make the difference. When it focuses on the product itself, specifically in the case of this study about the automotive industry, which is a very competitive segment in the world, it is necessary much more sophisticated strategies or even non-existent yet. Mentioned by several leaders and executives of multinational companies as an efficient methodology, the Design for Six Sigma, or simply DFSS, enables to understand their markets, their customers, respective necessities and yearnings, in a deep way and their deployments as well. By the flexibility of using DFSS methodology, it becomes possible to develop proposals and solutions to one of the most important differentials in this competitive market, the innovation. Due to the subjectivity around some aspects of the concept of that differential, it is proposed to adopt the fuzzy logic, to work on the most important linguistic variables and, combined with the Taguchi’s signal to noise relation, quantitatively measure the degree of innovation inherent in the products. By this modeling, validated through the analysis of several vehicular systems that have evolved throughout the automobile history, it becomes possible to compare current products with new ideas and proposals from the point of view of innovation, thus providing useful inputs to the decision-making process

Bechtel Chile Limitada tiene la responsabilidad de ejecutar el proyecto Repotenciamiento II de Minera Los Pelambres. En el marco de este proyecto Bechtel Chile espera recibir, en un plazo de 2 años, cerca de 16.000 documentos técnicos procedentes de órdenes de compra que generará con sus proveedores de bienes o servicios. Dichos documentos incluyen planos, memorias de cálculo y especificaciones técnicas que serán utilizados por Bechtel para desarrollar la Ingeniería del proyecto. Cada documento debe ser revisado por la gerencia de Ingeniería para comprobar que satisfaga sus necesidades de información. El documento será aprobado en caso que cumpla lo requerido por Bechtel o rechazado y comentado en la eventualidad que se precisen modificaciones. Para el proceso de revisión de documentos, Bechtel ha definido como aceptable para todos sus proyectos hasta 3 ciclos de revisión por documento. Inicialmente, un 10% de los documentos supera este límite, lo que se estima producirá 2.357 revisiones sobre la norma de servicio. Con un costo promedio estimado por revisión de 96,91 USD, se deriva que el costo de la mala calidad asociado a este proceso, alcanza los 228.417 USD. Utilizando la metodología Six Sigma, se han identificado las fallas en el proceso y se han buscado las causas de cada una de ellas y su probabilidad de ocurrencia y detección. Utilizando esta información, se ha determinado la criticidad de cada fuente de error. Para las más críticas, se han introducido modificaciones en la tecnología utilizada – permitiendo que la coordinación, revisión y aprobación de los documentos sea realizada digitalmente, en el proceso – se han eliminando tareas que no aportan valor y que sólo son fuentes de error, y se han reorientado algunos roles para hacerlos más activos en el seguimiento del proceso. Como resultado de las modificaciones señaladas, se ha logrado mejorar el número de Sigmas del proceso desde 0,8 a 2. Lo anterior se traduce en que el número de documentos que supera las 3 revisiones se reduce a sólo un 2,5%, lo que equivale a 566 revisiones adicionales. Por otra parte, se ha logrado disminuir el tiempo de cada revisión, con lo cual su costo se ha disminuido a 48,8 USD. En base a lo anterior, el costo de mala calidad para el proyecto se ha disminuido a 27.620 USD, lo que implica un ahorro total de 200.797 USD o un 88% del costo inicial. Este resultado permite proyectar que la implementación de estas mejoras en los restantes proyectos de Bechtel Chile producirán un ahorro de aproximadamente 1.400.000 USD en los próximos 5 años.

Introdução: Doentes Hepáticos mesmo após o Transplante de Fígado (TF) apresentam heranças fisiopatológicas que podem influenciar na diminuição da Capacidade Funcional (CF). Objetivo: Traçar o perfil dos pacientes pós TF em relação à CF, e definir quais os melhores exercícios físicos para compor futuro programa de condicionamento físico dos pacientes, tanto antes como depois do TF. Métodos: Estudo transversal com 52 pacientes submetidos ao TF entre os anos de 2002 e 2013. Foi realizado o Teste de Caminhada de 6 minutos (TC6). Resultados: 51,9% dos pacientes eram homens, sendo a média de idade da amostra 58 + 10,26 anos. Entre os participantes, 48,1% eram hipertensos, 42,3% obesos e 40,4% tinham diabetes tipo II. Tacrolimus é o medicamento mais utilizado em 84,6% dos pacientes. O DPTC6 média total foi de 497 + 90 metros, onde os homens andavam distância média mais alta que as mulheres (531 + 70 e 460 + 95 metros respectivamente). Sexo e Idade foram significativas (p=0,002 e p=0,011), evidenciando que a média do TC6 é maior em homens mais jovens do que em mulheres, independentemente do tempo transcorrido após o TF (p>0,05). Em relação a prática de exercícios físicos, apesar de não ser estatisticamente significativa, evidenciou-se que praticantes possuem melhores DPTC6. Conclusão: A DPTC6 por pacientes já submetidos ao Transplante de Fígado no Hospital de Clínicas de Porto Alegre, é indicativa de boa capacidade funcional, principalmente entre os pacientes mais jovens, os do sexo masculino e praticantes de exercícios físicos. / Introduction: The pathophysiological profile of patients with liver disease may impact functional capacity even after liver transplantation (LT). Objective: To describe functional capacity after LT in a group of Brazilian patients. Methods: This cross-sectional study included 52 patients submitted to LT between 2002 and 2013. Functional capacity was determined using the six-minute walk test (6MWT). Results: The mean age of the overall sample was 58 ± 10.26 years, and 51.9% were male. Hypertension was detected in 48.1%, obesity in 42.3%, and type 2 diabetes in 40.4%. Tacrolimus was the most used medicine (84.6% of patients). The mean distance traveled in the 6MWT was 497 + 90 m (531 ± 70 m for males vs. 460 ± 95 m for females). Gender and age were significantly associated with 6MWT results (p=0.002 and p=0.011), showing a higher mean 6MWT distance in younger men than in women, regardless of the time elapsed since LT (p<0.05). In relation to physical exercise, physically active individuals had more favorable 6MWT results; however, this association was not statistically significant. Conclusion: The present group of LT patients had good functional capacity as measured by the 6MWT, especially younger patients, male patients, and physically active patients.

Cette thèse a été réalisée dans le cadre d'un partenariat entre le CRAN et l'entreprise TRANE. Elle propose une méthodologie pour l'intégration et le développement de Systèmes Contrôlés par le Produit (SCP). Celle-ci a vocation de permettre d'implémenter une architecture de contrôle par kanbans et/ou produits « actifs », adaptable aux systèmes de production d'une entreprise. Le premier chapitre de la thèse décrit le contexte industriel. A l'issue de ce chapitre émerge les problèmes de synchronisation de flux de J'entreprise. Le second chapitre présente une étude bibliographique des stratégies existantes de pilotage de flux et apportant donc des éléments de réponse à ces problématiques. Après avoir montré l'apport des systèmes contrôlés par le produit dans la résolution de ceux-ci, ce chapitre montre le besoin de méthodes d'ingénierie pour concevoir un SCP adapté « au plus juste » au système industriel étudié. Le troisième chapitre est consacré à la définition de la problématique scientifique. En réponse à celle-ci, la proposition d'une méthodologie de conception et d'intégration des systèmes contrôlés par le produit est présentée dans le quatrième chapitre. Cette méthodologie s'appuie sur l'approche d'ingénierie système «six-sigmas »pour piloter le projet de conception du SCP par des indicateurs issus des besoins des utilisateurs. L'utilisation de la simulation événementielle permet de concevoir l'architecture la plus pertinente au regard des indicateurs de performance retenus et de valider a priori l'intégration du SCP ainsi conçu dans son environnement. Le dernier chapitre a pour objectif d'illustrer l'approche sur des cas réels d'application. / The PhD research was made in the context ofan industrial partnership between Trane Company and the CRAN. The main objective ofthis work is to propose atnethodol6gy to integrate and design Product Driven Systems (PDS). This research proposes a control architecture irnplementation by active kanbans and/or active products in manufacturing systems context. The fust chapter describes the manufacturing processes of Trane Company. At the end of this chapter industrial problems are highlighted. The second chapter is a bibliographical study relative to manufacturing flow control existing processes leading to improvements for preceding problems. Following the demonstration of the interest of PDS and their resolution, the necessity of special PDS design method adapted to the industrial context is shown in chapter 2. The third chapter describes the scientific objectives induced by the previous problems and by the lack of PDS integration and design methods. The main contribution of this thesis rises in the proposed methodology. Moreover, several applications have been proposed in order to validate the methodology and results highlight PDS concept pertinence.

abstract: The ever-changing economic landscape has forced many companies to re-examine their supply chains. Global resourcing and outsourcing of processes has been a strategy many organizations have adopted to reduce cost and to increase their global footprint. This has, however, resulted in increased process complexity and reduced customer satisfaction. In order to meet and exceed customer expectations, many companies are forced to improve quality and on-time delivery, and have looked towards Lean Six Sigma as an approach to enable process improvement. The Lean Six Sigma literature is rich in deployment strategies; however, there is a general lack of a mathematical approach to deploy Lean Six Sigma in a global enterprise. This includes both project identification and prioritization. The research presented here is two-fold. Firstly, a process characterization framework is presented to evaluate processes based on eight characteristics. An unsupervised learning technique, using clustering algorithms, is then utilized to group processes that are Lean Six Sigma conducive. The approach helps Lean Six Sigma deployment champions to identify key areas within the business to focus a Lean Six Sigma deployment. A case study is presented and 33% of the processes were found to be Lean Six Sigma conducive. Secondly, having identified parts of the business that are lean Six Sigma conducive, the next steps are to formulate and prioritize a portfolio of projects. Very often the deployment champion is faced with the decision of selecting a portfolio of Lean Six Sigma projects that meet multiple objectives which could include: maximizing productivity, customer satisfaction or return on investment, while meeting certain budgetary constraints. A multi-period 0-1 knapsack problem is presented that maximizes the expected net savings of the Lean Six Sigma portfolio over the life cycle of the deployment. Finally, a case study is presented that demonstrates the application of the model in a large multinational company. Traditionally, Lean Six Sigma found its roots in manufacturing. The research presented in this dissertation also emphasizes the applicability of the methodology to the non-manufacturing space. Additionally, a comparison is conducted between manufacturing and non-manufacturing processes to highlight the challenges in deploying the methodology in both spaces. / Dissertation/Thesis / Ph.D. Industrial Engineering 2011

The research regarding the six day war and the aerial operations named Operation Moked is extensive but there are certain shortcomings in the research that examines both the operation and the principle of surprise. The aim of this paper is to contribute to this research by utilising existing military theories on the principle of surprise in order to identify indicators that are representative of surprise.  These indicators are thereafter used in a study of Operation Moked in order to examine the extent of in which the principle was utilised. The result of this research goes to show that the principle of surprise was utilised in great extent by Israel during Operation Moked. / Det har bedrivits mycket forskning kring Sexdagarskriget och det lyckade israeliska luftanfallet Operation Moked men det finns vissa brister i forskningen på operationen kopplat till krigföringsprincipen överraskning. Denna uppsats syftar till att bidra till detta forskningsläge genom att använda militära teoribildningar kring principen överraskning och bryta ut indikatorer på vad som kännetecknar principen. Dessa indikatorer används sedan i en studie av Operation Moked för att undersöka i vilken utsträckning principen tillämpades. Resultatet av denna undersökning påvisar att överraskning tillämpades i stor utsträckning av Israel under Operation Moked.

The submitted diploma thesis provides a detailed description of lean production in Avon Automotive Inc., Rudník. The essential aim was to demonstrate this method on workplace redesign via gradual production improvement. At First, specific terms are properly explained in a theoretic way. Lean production is fully clarified too. The author also mentioned methods which are bound to be adopted. Amongst the major Japanese methods are 5S, Kaizen, Kanban, and Ongoing improvement. It is history of the company, its current conditions, customers and competitors which are carefully looked into in the next part. Economic issue is then tackled with the focus on the last 6 years of the company economic development. Approval process, current company project conditions as well as production and logistics procedures descriptions are also provided within the thesis. The author eventually put emphasis on defying lean production with close attention to employees' training in which the author herself participated, and then gradual improvement phase is clearly marked in three steps. The diploma thesis includes SWOT analysis of the entire project. The author evaluates strong and weak sides of the company, its threats and opportunities. The thesis finally suggests that each job position should be maintained. It is all discovered facts of the whole project which are conveniently summarized at the end.
