The demands of the market for short delivery periods make planning and control of multistage, customer order-oriented production difficult and complex. This is true especially for the semi-finished products industry, the semiconductor industry, the food processing industry, the paper industry, as well as parts of the chemical industry. So far, neither rough scheduling PPS (Production Planning and Control)-systems nor disjoint 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 from globally coordinated planning and short-term production control with distributed cooperative local control stations. The expected benefits of such a system are reduced inventories and lead times (by about 30%) and an increase of the delivery reliability (by about 60%). In the past few years, the Fraunhofer Institute for Manufacturing Engineering and Automation (IPA) has developed a system architecture which meets these demands. A prototype is currently being used successfully in industrial processes.
