IMPLEMENTING LEAN SIX SIGMA METHODOLOGY IN THE OIL INDUSTRY: GENERAL FRAMEWORK

Jaber, Mohammed Abdali 01 December 2013 (has links)
The oil industries constitute a significant part of global economic, depending on whether the value of its output, exports or jobs created. The industry affects directly the national economy, and contributes to Gross Domestic Product (GDP). Oil industries are considered the main supplier for many sectors such as industrial, transportation and so forth. On the other hand, the oil industry has faced many problems such as environmental impact, exhausts, climate change, waste, and safety; as well as customers' and employee dissatisfaction. Errors and waste in the oil industry have serious costs and consequences. Hence, a systematic methodology of quality in the oil enterprise has become an urgent necessity to minimize or eliminate waste and provide a health, safety, and environment (HS&E) performance. One of the most efficient systems of quality is the integration between Six Sigma methodology and Lean Enterprise. Lean Six Sigma (LSS) has become widely used in several areas such as manufacturing, service, and health care. The research literature does not provide a framework for implementing Lean and Six Sigma in the oil industry. A systematic general framework of the LSS implementation is developed which includes eight steps - statement, leadership, committee, deployment, prioritize, implement, review, and finalize. Then, the effectiveness of the LSS methodology of solving problems that the oil industry faces was demonstrated by providing several case studies applied successfully in different areas in the oil enterprise.

No. of bitstreams: 1 Jefferson Assis de Faria.pdf: 2128442 bytes, checksum: 5140fbde576a07cdf1f0e836e1059565 (MD5) Previous issue date: 2014-08-04 / It is notorious how often and fast most of companies, in the global environment, take decision on establishing goals to achieve near perfect quality for a product or service through the implementation of better process and new tools. Six Sigma as example is one of the methodology in which the adherence has been massive and constant in the business world, however, few companies take advantage of this tool in their administrative processes, mainly speaking, in the product and services pricing process (FRANK, 2003). The heart of the matter is that many organizations use the disciplines of Six Sigma to reduce their manufacturing costs, therefore, they also can use the same tool to increase their revenue in the way to reduce losses and minimize tension on management decision process, which means, apply Six Sigma not only on manufacturing process but others (SODHI and SODHI, 2005). Facing this opportunity, hereby the main goal of this research, through the Six Sigma methodology and its new approach Six Sigma Pricing, is to perform a sales pricing process diagnosis and analysis in order to propose improvements to an automotive industry supplier. Due to some limitations to apply full DMAIC (Define, Measure, Analyse, Improve and Control) steps, which is the Six Sigma (Pricing) methodology s pillars, it were only applied in this research the first three phases so-called DMA (Define, Measure, Analyse) and in the Improve phase it were done the process improvements proposals. It was firmly believed that applying these first three phases in the company pricing process was very valuable to bring out the various "flaws"/problems and their "countermeasures"/proposals for potential solution thereof. Therefore, it is understood that the practical and theoretical contributions resulted from this research proved that the methodology and its tools are powerful in all its phases to come up with potential pricing troubleshooting. / É notória a frequência e agilidade com que as empresas, no ambiente global, decidem o estabelecimento de metas para atingir níveis quase perfeitos de qualidade de seus produtos e serviços através da implantação de melhores processos e novas ferramentas. O Six Sigma é uma das metodologias cuja aderência tem sido massiva e constante nos negócios, porém, poucas companhias utilizam desta ferramenta, em seus departamentos administrativos, e principalmente no que tange ao processo de formação do preço de produtos e serviços (FRANK, 2003). O fato é que muitas organizações usam das disciplinas do Six Sigma para reduzirem seus custos de manufatura, portanto, eles também podem usar a mesma ferramenta para aumentar as suas receitas de maneira a reduzir perdas e minimizar as tensões nas decisões de negócio , ou seja, aplicar a metodologia Six Sigma em outros processos que não os de manufatura (SODHI e SODHI, 2005). Dada esta oportunidade, esta pesquisa teve como objetivo, através da metodologia Six Sigma e sua nova abordagem Six Sigma Pricing, fazer o diagnóstico e análise do processo de formação do preço de venda em um fornecedor da indústria automobilística para propor melhorias. Em função de limitações, quando da aplicação completa do DMAIC (Define, Measure, Analyze, Improve and Control), pilares da metodologia Six Sigma (Pricing), foram aplicadas somente as três primeiras fases assim chamadas neste trabalho de DMA (Define, Measure, Analyze) e na fase de Improve foram feitas as propostas de melhoria para o processo. Pôde-se crer piamente que aplicar estas três primeiras fases foi de grande valia para trazer à tona os mais diversos defeitos /problemas e as suas respectivas contramedidas /propostas para solução potencial dos mesmos. Entendeu-se então que as contribuições práticas e teóricas advinda desta pesquisa prova que a metodologia e suas ferramentas são poderosas em todas as suas etapas para resolução de problemas de pricing.

Aspen continues to deliver on its commitment toward playing a role in social responsibility diseases such as HIV/AIDS, tuberculosis and malaria. In August 2003 Aspen developed Africa’s first generic anti-retroviral drug, namely Aspen-Stavudine. Aspen’s manufacturing facilities are based in Port Elizabeth (PE) and East London. Aspen has recently completed an Oral Solid Dosage (OSD) manufacturing facility worth approximately R150 million in PE. The Group manufactures approximately 20 tons of product daily and in excess of 400 tons of solid dosage pharmaceuticals, which equates to more than 2 billion tablets. In addition, more than 3 million litres of liquid pharmaceuticals and over 200 tons of pharmaceutical creams and ointments are produced per year [1]. Aspen excels at delivering quality products and services, exceeding customer expectations, complying with international standards in an environment that cultivates technical expertise and innovation. Following this philosophy through to the shop floor areas mean that there are always initiatives in continuous production improvement. One of these improvement projects introduced is called Six Sigma. 8 Ten members of the staff, selected from different expertise fields in the company were trained in Six Sigma. Knowledge gained from the two week training course were applied to different areas in the factory using Six Sigma principles. This dissertation focuses on the study undertaken in one of production areas, namely the filling process of the ointments and creams at the Aspen Port Elizabeth facility.

La presente investigación consistió en el desarrollo de un modelo de gestión basado en Six Sigma para optimizar el proceso de formalización de minería artesanal y pequeña minería en la región de Ancash. Primero, se realizó un diagnóstico de la situación actual de la informalidad en el sector minero en la región Ancash, identificando la cantidad total de mineros registrados al proceso de formalización, con sus ubicaciones geográficas. Después se analizó las normativas actuales de formalización minera para pequeña minería emitidas por el Ministerio Energía y Minas del Perú como el Decreto Legislativo N°1293 publicada el 30 de diciembre de 2016 y el último Decreto Legislativo N° 1336 denominada Proceso Formalización Minera Integral publicada el 6 de enero del 2017. Posteriormente, se aplicó la metodología Six Sigma con sus 5 fases: medir, definir, analizar, mejorar y controlar; las cuales ayudan a determinar estadísticamente la situación actual y se analizó el proceso de formalización de los mineros informales en la región, también se midió la cantidad de documentación presentada, los tiempos demorados en evaluación de los documentos, y se identificó las dificultades de los mineros para formalizar; seguidamente se propone una mejora para la principales dificultades. Finalmente se desarrolló un modelo con propuestas para incrementar la formalización de los mineros artesanales y pequeños mineros en base a las condiciones identificadas para la región Ancash. / The present investigation consists in the development of a management model based on Six Sigma to modify the formalization process of artisanal and small-scale mining in the Ancash region. First, a diagnosis was made of the current situation of informality in the mining sector in the Ancash region, identifying the total number of miners registered to the formalization process, with their geographical records. Then, the current mining formalization regulations for small mining issued by the Ministry of Energy and Mines of Peru were analyzed as Legislative Decree N° 1293 published on December 30, 2016 and the last Legislative Decree N° 1336 published. Comprehensive Mining Formalization Process published on January 6, 2017. Subsequently, the Six Sigma methodology was applied with its 5 phases: measure, define, analyze, improve and control; which help to determine statistically the current situation and the formalization process of informal miners in the region was analyzed, the amount of documentation presented, the time delayed in the evaluation of the documents, and the difficulties of the Miners to formalize then propose an improvement for the main difficulties. Finally, a model was established with proposals to increase the formalization of artisanal and small-scale miners based on the conditions identified for the Ancash region. / Trabajo de investigación

Six Sigma es una de las herramientas más completas para realizar implementaciones de mejora continua en una organización, además es reconocida su eficacia y eficiencia en la implementación a nivel mundial en diferentes organizaciones, especialmente en medianas y grandes empresas. Es reconocido el éxito de la herramienta en empresas como Motorola, creadora de la herramienta, y General Electric, que empleo la herramienta en extremo, descrito esto, algunos autores definen Six Sigma como una herramienta de mejora continua, pero de largo plazo, que requiere de la recolección y análisis de una gran cantidad de datos para la resolución de problemas complejos y muy arraigados en las organizaciones, especialmente diseñada para enfrentar problemas propios de las grandes empresas. Por otro lado, Kaizen y los círculos de la calidad son herramientas de mejora introducidas en la década de 1980, por el auge industrial del Japón. Estas herramientas, se consideran como de menor complejidad en comparación al Six Sigma y de más fácil y práctica implementación, trabajando con datos primarios y herramientas estadísticas básicas, para la resolución de problemas. Siendo alternativas que se anteponen a la implementación de Six Sigma por su relativa mayor facilidad de implementación. El objetivo del presente trabajo de investigación es identificar los Mitos, Barreras y Factores Críticos de Éxito de la herramienta Six Sigma en empresas PYMES, con el propósito de realizar un aporte para las futuras empresas que opten por la aplicación de esta herramienta, como alternativa y/o complemento en sus esfuerzos de mejora continua. / Six Sigma is one of the most complete tools to implement continuous improvement implementations in an organization, and its efficiency and effectiveness in worldwide implementation is recognized in different organizations, especially large companies and medium companies. It is recognized the success of the tool in companies such as Motorola, creator of the tool, and General Electric, who used the tool in extreme, described this, some authors define Six Sigma as a tool for continuous improvement, but long term, which requires of the collection and analysis of a large amount of data for the resolution of complex and deeply rooted problems in organizations, especially designed to face problems typical of large companies. On the other hand, Kaizen and the quality circles are tools of improvement introduced in the compared to the Six Sigma and are easier and more practical to implement, working with primary data and basic statistical tools to solve problems. Being alternatives that precede the implementation of Six Sigma for its relatively greater ease of implementation. The objective of this research work is to identify the key elements for the successful implementation of the Six Sigma tool in SMEs, with the purpose of making a contribution for future companies that choose to apply this tool, such as alternative and / or complement in its efforts of continuous improvement.Sección obligatoria en la que el autor o los autores exponen en breves líneas lo esencial del trabajo. / Trabajo de Suficiencia Profesional
