The paper presents a database-based method to reduce the development time and project lead-time for large discreteevent simulation models of entire factories. The database used to automatically generate and drive the simulation model is a copy of the production planning database. A set of proof-of-concepttools and a database have been generated to verify the method and it has been shown that it is feasible to run a simulation using the production planning data as the only information source. The software developed is modular and designed to work in heterogeneous environments. The method is expected to reduce the modeling and maintenance effort considerably when modeling entire factories. The method will result in a holistic and fairly accurate assessment of performance measures for an entire factory.
