RESUMO

The globalization strengthens the necessity for companies to improve its processes and products in order to remains competitive and to attend expectations of a dynamic market and shareholders each time more demanding and eager to maximize their profits. The continuous improvement mentioned above, is not related only to the quality perceived by the final consumer, but also to the quality and reliability of the production processes. Therefore, as better processe the company gets, as better would be their final products and as lower would be the costs. However, the question is wheter a continuous improvement using Six Sigma could benefit from the design documentation for the target process returning also an improved documentation after the cycle is completed. This work considers the use of Petri Nets for production processes modeling - even if any other design and modeling representation would return similar results - supporting the Six Sigma methodology application. The main result is a proposition of continuous improvement life cycle that maintains the design documentation consistent and up-to-date. Thus, this work pursuits the integration between the teams that design processes and those who implement them in the manufacturing plant. To show the potential of the models analysis during Six Sigma projects a case study is analyzed for the Press Shop area in an Automotive Industry.
