Implantação do modelo lean thinking em saúde: um estudo de caso em serviço de medicina diagnóstica / Implementation of lean thinking model in healthcare: a case study in medicine diagnostic service.Eiro, Natalia Yuri 24 November 2014 (has links)
Os desperdícios e a necessidade de oferecer um atendimento de qualidade constituem um verdadeiro desafio para as empresas de saúde. Para tanto, a adoção da filosofia enxuta - particularmente do lean healthcare - pode contribuir para a redução dos desperdícios e melhoria da qualidade. Neste contexto, este trabalho teve como objetivo analisar os motivos e como ocorreu a implantação do lean thinking nos processos de atendimento em uma empresa de medicina diagnóstica, bem como identificar os resultados alcançados. MÉTODOS: Trata-se de uma pesquisa exploratória de abordagem qualitativa, em que foi realizado um estudo de caso incorporado. Para a construção das questões orientadoras das entrevistas realizou-se uma pesquisa bibliográfica que gerou seis temas: operações, cultura organizacional, apoio da alta administração, redução de custos e desperdícios, foco no cliente e comunicação e capacitação. A coleta de dados foi realizada com dez participantes, divididos em três grupos e por meio de observações diretas. RESULTADOS: O modelo lean thinking foi aplicado na empresa pela iniciativa de líderes que conheciam o modelo. No entanto, ocorreu de forma incompleta - os colaboradores operacionais não foram envolvidos na capacitação inicial; os princípios básicos e ferramentas que fundamentam o modelo lean não foram incorporados como modelo de trabalho da empresa; não houve a integração de toda a organização, da alta administração à operação; os clientes não participaram do mapeamento do fluxo dos processos do atendimento e não avaliaram o que agrega valor. Com isso, os resultados alcançados em relação à redução de desperdícios com geração de valor ao cliente e melhoria da qualidade com a implantação do lean foram pontuais, com pouca adesão das lideranças e equipe de colaboradores. CONCLUSÕES: A análise dos resultados sugere que a implantação parcial da metodologia do lean thinking e suas práticas seguindo a literatura, considerando o contexto da organização, pode ter contribuído para a obtenção de um desempenho aquém do esperado, em termos de qualidade e redução de desperdícios. / The waste and the need to offer a quality service are a real challenge for healthcare companies. To this end, the adoption of lean philosophy - particularly the lean healthcare - can contribute to reduce waste and improve quality. In this context, this study aimed to analyze the reasons and how the implementation of lean thinking occurred in the processes of care in a medical diagnostic company, as well as identify the results achieved. METHODS: This was an exploratory qualitative study, in which an embedded case study was conducted. For the construction of the guiding questions of the interviews we carried out a literature search that yielded six themes: operations, organizational culture, top management support, cost reduction and waste, customer focus and communication skills. The data collection was performed with ten participants, divided into three groups and through direct observations. RESULTS: The lean thinking model was applied in areas of the company by the initiative of leaders who knew the model. However, there was incomplete - operational employees were not involved in the initial training; the basic principles and tools that support the lean model were not incorporated as a working model of the company; there was not integration of the entire organization, from top management to the operation; customers did not take part on the flow mapping of the processes of care and did not evaluate what adds value in customer perception. Thus, the results achieved regarding wastes decrease with customer value development and quality improvements through lean deployment were punctual and presented poor uptake from leadership team and employees. CONCLUSIONS: The assay of achieved results suggests that the incomplete lean thinking methodology deployment and its best practices according to the literature, also taking into consideration the context among enterprise under study, may have contributed for achievements lower than expected, in relation to quality and wastes decrease.

An integrated decision support framework for the adoption of lean, agile and green practices in product life cycle stagesUdokporo, Chinonso Kenneth January 2017 (has links)
In order to stay competitive in today’s overly competitive market place, businesses must be engineered to match product characteristics and customer requirements. This increased emphasis on achieving highly adaptive manufacturing with reduction in manufacturing costs, better utilization of manufacturing resources and sound environmental management practices force organisations to adopt efficient management practices in their manufacturing operations. Some of the established practices in this context belong to the Lean, Agility and Green (LAG) paradigms. Adopting these practices in order to address customer requirements may require some level of expertise and understanding of the contribution (or lack of it) of the practices in meeting those requirements. Primarily, the wide choice of LAG practices available to address customer requirements can be confusing and/or challenging for those with limited knowledge of LAG practices and their efficacy. There is currently no systematic methodology available for selecting appropriate LAG practices considering of the product life cycle (PLC). Therefore, this research provides a novel framework for selecting appropriate LAG practices based on PLC stages for reducing costs, lead time and generated waste. The methodology describes the application of analytic hierarchy process (AHP), statistical inference and regression analysis as decision support tools, ensuring a systematic approach to the analysis with appropriate performance measures. The data collected were analysed with the aid of SPSS and Excel using a variety of statistical methods. The framework was verified through a Delphi study and validated using a case study. The key findings of the research include the various contributions of lean, agile and green practices towards improving performance measures, the importance of green in improving performance measures and the importance of selecting appropriate practices based on product life cycle stages. This research makes a clear contribution to existing body of knowledge by providing a methodological framework which could serve as a guide for companies in the FMCG industry to systematically integrate and adopt lean, agile and green to better manage their processes and meet customer requirements in their organisations. However, the framework developed in this research has not been tested in other areas.

Recomendações para a implantação da Manufatura Enxuta considerando os propósitos da Produção mais Limpa / Recommendations for the implementation of Lean Manufacturing considering proposals for Cleaner ProductionQueiroz, Geandra Alves 04 May 2015 (has links)
As empresas operam em um ambiente cada vez mais dinâmico e competitivo, tornando imprescindível atender adequadamente às necessidades dos consumidores. Na atualidade, estas demandas foram ampliadas e, além de custo, qualidade, velocidade de entrega e flexibilidade, identifica-se um mercado que passa a cobrar pela redução dos impactos ambientais gerados pelos produtos e processos. Deste modo, esta pesquisa defende a proposição de que a Manufatura Enxuta, uma filosofia de gestão da produção, somada aos propósitos da Produção mais Limpa (PmaisL), uma estratégia de gestão ambiental para sistemas produtivos, pode ser uma solução para o alinhamento de seus objetivos, visto que ambas buscam o aumento de produtividade e a eliminação dos desperdícios. Para a implantação da Manufatura Enxuta não foi determinado um método que oriente como realizar este processo e quais são as práticas essenciais, além de ter poucas pesquisas que buscam compreender os fatores disto. Do mesmo modo, pesquisas que abordem a Manufatura Enxuta e a PmaisL ainda são preliminares. Neste sentido, o objetivo desta pesquisa foi propor recomendações para a implantação da Manufatura Enxuta considerando os propósitos da PmaisL, estruturadas no ciclo de melhoria contínua do método DMAIC. O método de pesquisa utilizado para alcançar o objetivo proposto foi o estudo de caso único em uma empresa de referência e o embasamento teórico foi pautado em uma revisão bibliográfica sistemática (RBS). Os resultados gerados com o desenvolvimento dessa pesquisa permitiram observar que não existe um método padrão para a implantação e que a literatura, de modo geral, aborda a implantação da Manufatura Enxuta como um processo de ciclos de melhoria continua envolvendo as atividades definir, medir, analisar, melhorar e controlar e também aborda o processo de implantação a ordem que as ferramentas e práticas devem ser implantadas. No que tange a RBS sobre PmaisL e manufatura enxuta foi possível extrair da literatura as compatibilidades e divergências entre as abordagens, recomendações para melhorar o desempenho ambiental dos sistemas enxutos, como os recursos humanos interferem na integração destas áreas e, além disso, como as práticas enxutas podem ser utilizadas para atingir os objetivos da PmaisL. Além disso, o estudo de caso permitiu observar empiricamente como o meio ambiente pode ser ponderado em um sistema de Manufatura Enxuta. Assim, com base nas evidências teóricas e práticas, gerou-se as recomendações, as quais poderão orientar as empresas de manufatura que desejam implantar as abordagens da Manufatura Enxuta e da PmaisL de maneira conjunta e obterem, simultaneamente, desempenho ambiental e econômico em suas melhorias. Ainda, foi possível concluir que apesar de existirem alguns trade-offs, estas abordagens são em grande parte convergentes. / Companies are operating in an ever more competitive and dynamic environment, making it essential to fulfil the consumers needs. Currently, these demands have expanded, and in addition to cost, quality, delivery speed and flexibility, it is possible to identify a market that requires reduction in the environmental impact of their products as well as procedures. Thus, this research supports the proposition that Lean Manufacturing, a production management philosophy, combined with Cleaner Production, the environmental management strategy for industrial systems, can be a solution for aligning goals, as both seek increased productivity and the elimination of wastage. In the implementation of Lean Manufacturing, there is as yet no method for guiding one to carry out this procedure, and to know what the essential operations are, as well as only having a few studies aimed to understand the factors involved. Similarly, the research addressing Lean Manufacturing and Cleaner Production remains at its initial stages. Thus, the objective of this research was to provide recommendations for the implementation of Lean Manufacturing considering Cleaner Production proposals, using the continuous improvement cycle structure from the DMAIC method. The research method used to achieve the proposed objective was a single case study in a notable company, and the theoretical framework was developed through a systematic literature review. The results, obtained through the development of this research, allowed us to observe that there was no standard method for deployment, and that the literature, in general, addressed the implementation of Lean Manufacturing as a process of cycles of continuous improvement, involving the defining, measuring, analyzing, improving and controlling activities; and also addressed within the implementation process the order in which the tools and operations should be implemented. With respect to RBS on Cleaner Production and Lean Manufacturing, it was possible to extract, from the literature, compatibilities and differences between the approaches; recommendations to improve the environmental performance of Lean systems, and how human resources interfered with the integration of these areas and, moreover, how the Lean operations could be used to achieve the objectives of Cleaner Production. In addition, the case study allowed the empirical observation of how the environment could be balanced in a Lean Manufacturing system. Thus, based on theoretical and practical evidence, the results generated recommendations, which could guide manufacturing companies that wanted to deploy in conjunction the approaches of Lean Manufacturing and Cleaner Production, and achieve both environmental and economical performances in their improvements. Furthermore, it was concluded that, although there are some trade-offs, these approaches are largely convergent.

Análise e discussão de causas de níveis elevados de inventário em uma empresa que se autodenomina enxuta: comparação entre cenários de simulação de dados reais de uma empresa do setor automotivo / Analysis and discussion of causes of high levels of inventory in a company that calls itself lean: comparison between simulation scenarios of real data of a company in the automotive sectorStella Yukiko Nakatsuka 27 October 2017 (has links)
O principal propósito deste trabalho é avaliar as principais variáveis que devem ser consideradas no dimensionamento do buffer de componentes de uma empresa que trabalha sob a ótica da Manufatura Enxuta, que devem ser fornecidos a uma célula de manufatura com mix variado de conjuntos similares a serem produzidos. Como mecanismo de validação da investigação, devido ao dinamismo inerente a operação de sistemas de produção com layout célular, foi utilizada a ferramenta Mapeamento de Fluxo de Valor com o apoio de uma estrutura de um software comercial de simulação computacional aplicando o otimizador do aplicativo desenvolvido a partir de um algoritmo genético a fim de contrapor o uso do abastecedor das células com o controle efetivo do nível de inventário do buffer. Como resultado são apresentados diferentes cenários definidos como experimentos tendo como principal fator a variação do tempo de ciclo de abastecimento executado e o fluxo de material como parâmetro inerente a demanda por cada um dos componentes consumidos na operação da célula de manufatura. Através das análises dos resultados foi concluído que os elevados níveis de estoque se tornam ou não necessários dependendo preliminarmente da capacidade de carregamento por ciclo de abastecimento do transportador e o tempo de ciclo necessário para a realização da atividade de ressuprimento. A relevância do tema de pesquisa estudado encontra-se na contribuição pertinente às informações adquiridas in loco na realidade de uma empresa que trabalha sob a ótica da Manufatura Enxuta, no crescente aumento da complexidade dos sistemas produtivos e, consequentemente, da dificuldade de análises mais precisas do impacto que as variáveis de fluxo, como por exemplo, tempo de abastecimento e movimentação, tempo de setup e os respectivos roteiros de fabricação podem causar no desempenho dos processos no chão de fábrica. / The main purpose of this work is to evaluate the main variables that must be considered in the component buffer dimensioning of a company that works with Lean Manufacturing, which to a manufacturing cell should be supplied with a varied mix of similar sets to be produced . As a research validation mechanism, due to the dynamism inherent in the operation of production systems with cell layout, the Value Stream Mapping tool was used with the support of a commercial software simulation structure applying the developed application optimizer from a genetic algorithm in order to counteract the use of the cell supplier with the effective control of the inventory level of the buffer. As a result, different scenarios defined as experiments are presented, the main factor being the variation of the supply cycle time executed and the material flow as a parameter inherent to the demand for each of the components consumed in the manufacturing cell operation. Through the analysis of the results it was concluded that high levels of stock become or not necessary depending on the loading capacity per transport cycle of the conveyor and the cycle time required to perform the resupply activity. The relevance of the studied research theme lies in the relevant contribution to the information acquired locally in the reality of a company that works from the perspective of the Lean Manufacturing, in the increasing complexity of the productive systems and, consequently, of the difficulty of more precise analyzes of the impact that the flow variables, such as supply and handling time, setup time and the respective manufacturing routes, can cause in the process performance on the shop floor.
