Leveransproblem : Ett problem vid strukturerad produktion

Axelsson, Cecilia January 2014 (has links)
When building large buildings, such as compartment buildings, there is a number of deliveries arriving on the construction site daily. In order to receive these deliveries without disturbing the rest of the work going on JM often books a fixed unloading time. When doing that they can be prepared when the delivery arrives. Making sure there is a suitable unloading area, someone to meet the delivery and when needed proper machines, such as a tractor or a crane, to help unload bigger deliveries. The person receiving the delivery is supposed to make an acceptance control where they check the delivered goods making sure nothing has been damaged in transport and that they have received what they were supposed to receive. Also noting whether the delivery arrived on time or not.   In 2010 JM introduced structured production as their take on lean, and thus working more effectively. Structured production at JM means that everyone in the company performs the same task in the same way according to a predetermined assembly instruction. It also includes a certain way to make time plans for the whole project as well as for the next 5 weeks. As for deliveries JM tries to order these as close to just in time as possible. That reduces keeping material in stock at the construction site and also handling this material more than necessary. Handling material in stock is a big source of accidents and takes time away from other work. However, it is very vulnerable to have essential supplies arrive to the construction site just when they are needed as a delay can ruin the whole timeline of the production.   This report aims, through qualitative studies, to find out how widespread the problem of late deliveries is at JM'S three construction sites in Uppsala and what JM is able to do to avoid it.   The study showed that if deliveries are delayed, it refers almost exclusively to 1-5h on the desired delivery date. Deliveries being delayed so that they do not arrive on the right day were very unusual. One of the questions in the interviews was also whether JM themselves could have a negative effect on deliveries arriving on time by making changes in their orders, but this seems to have no significance when changes are made only after approval by the supplier and that the vast majority of deliveries after all still arrives on the right day. It rather seems that some providers take the order of a fixed unloading time less seriously. Something that does not make things better is that the procedure for handling delayed deliveries varies a lot just between the three construction sites in Uppsala and also between supervisors on the same construction site. It is not even always the case that the supplier is notified that the delivery was late, and then they do not know that they need to improve. Most suppliers buy in the transport of a shipping company and order a fixed unloading time from them. The suppliers interviewed all said that they wanted to know if the delivery was late so that they can contact the shipping company.

Com um layout eficiente é possível racionalizar os esforços para a agregação de valor aos produtos, através da diminuição de atividades que não contribuem para esta adição de valor. Exemplos destas atividades são o transporte de produtos em processamento, o fluxo de produção em contra corrente e os estoques intermediários. No sistema de produção Just in Time, o layout industrial, além de reduzir o número de atividades que não agregam valor, deve também possibilitar a flexibilização dos meios de produção e a integração da manufatura, atributos que podem implicar em vantagem competitiva em relação a empresas concorrentes, pois dotam a fábrica de uma grande velocidade de resposta frente as exigências do mercado. O uso do computador para o projeto do layout industrial deve-se ao fato de que por meio deste é possível sistematizar o processo de projeto, permitindo que as tomadas de decisão sejam feitas de acordo com regras claras e bem definidas, além de ser possível contar com extensas bases de dados. O modelo computacional desenvolvido neste trabalho visa superar alguns pontos fracos apresentados por softwares já existentes que se dedicam ao projeto do layout industrial, além de inserir este projeto no contexto do sistema Just in Time.

O impacto do just-in-time no sistema de controle organizacional : um estudo de caso na Hering Textil S.A.

Para este fim, foi empregado o método do estudo de caso que possibilitou analisar em detalhes os controles sobre o processo produtivo, sobre o controle de qualidade, bem como o controle sobre as pessoas. Através de uma avaliação longitudinal, foram focalizados os momentos anterior e posterior à introdução do just-in-time na área operacional da Hering Têxtil S/A. Os resultados obtidos demonstram a ocorrência de uma série de alterações no sistema de controle organizacional, como a intensificação dos controles sobre o processo e sobre as pessoas, a modificação nos mecanismos de controle de qualidade e, por último, a diminuição dos níveis hierárquicos, paralelamente, ao aumento da amplitude de controle dos supervisores, no nível operacional.

O aprimoramento de um processo produtivo pelo sistema "Just In Time" ajuda uma empresa manufatureira a alcançar vantagem competitiva em custo

A abordagem é sistêmica, partindo da ênfase da necessidade de se elaborar uma estratégia bem fundamentada no conhecimento da indústria e do seu meio ambiente, passando pelo conhecimento do sistema Just In Time e seus principais objetivos, conceituando o custo real (valor agregado) e definindo os indicadores de produtividade e qualidade. Em seguida identificam-se os desperdícios da produção e apresentam-se as ferramentas do Just In Time para combate-los, dando uma atenção especial ao sistema kanban e ao sistema da qualidade. O estudo de caso na Ericsson Telecomunicações contribui para melhor compreender a implementação e eficácia do sistema JIT. / Abstract : This work studies the Just in Time (JIT) philosophy of manufacturing administration, focusing the productive process improvement - in terms of productivity and quality gains - as a strategy to support a company to reach competitive advantage in cost. The adopted approach is systemic, initiating by emphasizing the necessity of elaborating a strategy very well based, on the knowledge of the industry and its operational environment, continuing with the application of the Just fn Time principles and its main objectives, conceptualizing the real cost (aggregated value) and defining the productivity and quality indicators. Finally, the study identifies the production wastefulness and the Just in Time tools to defeat them, with special attention on the Kanban system and on the quality system. The Ericsson Telecommunications case study contributes for a better understanding of the JIT system implementation and efficacy. / Mestrado / Mestre em Qualidade
