The market demands for short delivery times make the planning and control of multistage, customer order-oriented production difficult and complex. This is especially true for the semi-finished products industry, semiconductor, food processing and paper industries as well as parts of the chemical industry. So far, neither rough scheduling PPC (Production Planning and Control)-systems nor decentralized local control stations have been able to manage the enormous coordination efforts for planning mulit-stage linked production. Thus, the objective is to develop an integrated system using globally coordinat ed planning and short-term production control and distributed cooperative local control stations. The expected benefits of such a system come in the form of reduced inventories and lead times (approximately 30 per cent) and an increase of the delivery reliability (approximately 60 per cent). In the past few years, the Fraunhofer Institute for Manufacturing Engineering and Automation (IPA ) has developed a system structure which meets these demands. A prototype is currently being used successfully in industrial processes.
