A typical task in the implementation phase of ERP systems consists in the choice of an appropriate lot sizing procedure and the setup of its parameters. The existing procedures do not deliver the best results for each business process. So, a business specific setup is required. Unfortunately, there is no knowledge of good parameter settings for typical business processes. Therefore, different parameter settings have to be tested out on real business processes over long periods (e. g. over several years). Of course, such an approach fails due to time restrictions. In addition, the literature argues that an automated software process — contrary to a physical process — is often never called in question or further optimized. An alternative offers a simulation of business processes which is controlled by an ERP system. In the laboratory of information science and production logistics (LIP) at the University of Applied Sciences, Regensburg, a pilot implementation of a system for simulating the control of production processes by the SAP R/3-System (SIM-R/3) was developed. SIM-R/3 allows such a simulation over long periods.
