Implementação de um sistema pull

Abstract

Desde a década de 50 que o conceito Lean se encontra enraizado em vários tipos de organizações, tendo estas sempre presente a eliminação de desperdícios de produção para assim obter vantagens competitivas sobre os seus concorrentes. Assim, é comum ouvirem-se expressões como “Lean Management” para designar uma gestão que visa a eliminação do desperdício e “Lean Manufacturing” para designar uma produção que ambiciona eliminar operações sem valor acrescentado. Um dos conceitos associados á filosofia Lean é o sistema Pull, onde ninguém a montante deve produzir um bem ou serviço até que o cliente a jusante assim o exija. Neste documento é apresentado um conjunto de acções de melhoria levadas a cabo num projecto com base na implementação de um sistema pull, recorrendo aos seus elementos, numa secção de produção de uma fábrica que opera segundo a filosofia Lean. A concretização prática deste projecto passou por duas fases distintas, a primeira fase contemplou a análise da situação actual onde foi possível retirar diversa informação acerca do funcionamento da secção em estudo bem como a identificação de problemas e desperdícios existentes na mesma. Numa segunda fase foram implementadas diversas melhorias de acordo com a visão futura, entre as quais a alteração de layout e definição de novos bordos de linha, a normalização do trabalho realizado pelo operador logístico da secção bem como o dimensionamento do supermercado de produto acabado. A realização deste projecto permitiu a obtenção de diversos ganhos ao nível de abastecimentos normalizados dos postos de trabalho, eliminação de operações sem valor acrescentado, ergonomia dos postos de trabalho, redução de operadores e disponibilidade de material para trabalho na secção.

Since the 50´s, the Lean concept can be found in several types of organisations that in order to obtain competitive advantages over their opponents use the elimination of production wastes. So, expressions like “Lean Management” to define a management that aims to eliminate the waste and “Lean Manufacturing” that defines the production which aims to eliminate operations without added value are common. One of the concepts associated to the Lean philosophy is the Pull system, where no sum can produce a good or service unless the client requires it. In this document a set of improvement actions is presented from a project based on the implementation of the Pull system, which appeals to its elements, in a factory’s production section that operates according to the Lean philosophy. The practical concretization of this project has had two different stages: the first stage contemplated the analysis of the present situation where it was possible to obtain a wide information on the functioning of the section (object of the study) as well as to identify the problems and existing wastes. On a second stage, several improvements were implemented according to the future vision amongst them the layout change and definition of the new edges of line, the normalization of the section’s logistic operator work and the dimensioning of finished product’s supermarket. To conclude, this project allowed us to get positive conclusions related to normalized working ranks supplying, eliminating operations without added value, working ranks ergonomics, reduction of operators and material’s availability for work in the section.
