RESUMO

To face increasing competitive pressures, companies still perform their main management functionsmaking use of standard pattem solutions. This occurs mainlywith regard to the activities of Production Planning and Control - PPC. Such solutions are normallyinsensitiveto the relations among operational parameters of the production system, and consequent1y,do not offer suitable support to the decisive process associated to the PPC. In this sense, this work proposes the use of the "Characteristic Curves" in the decentralized PPC systems (subdivided in Production Units). These curves describe the relations between levels of work in process, flow time and leveI of the system utilization. To establish these relations, a methodology was developed based on discrete simulation techniques, which is applied in Production Units, through a practical case study. The results show that the process of determination of the curves by making use of simulation techniques is viable, as well as that the utilization of the curves can represent an important tool to the control of production flow. It is also shown that the obtained curves can be adjusted in a continuous improvement process ofthe production system modeling
