An Application of Coloured Petri Nets to Business Process Reengineering

An approach to business process reengineering (BPR) is presented and illustrated in the paper. The approach is based on Coloured Petri Nets (CPN) as a general tool for modeling, simulation and analysis of system processes. In realization of a BPR project there are two crucial phases in which the AS-IS model and the TO-BE model are created. This implies the use of the appropriate techniques for business process modeling and analysis. How CPN can be used for this purpose is illustrated here on the example of operation production planning in a pharmaceutical company. The processes are described by use of concept of dependencies and coordination mechanism as well as by use of decomposition and specialization concepts. It is shown that CPN can handle these concepts in an easy way. The produced net is hierarchical, stochastic coloured Petri net. Applying well-know software package Design/CPN, simulation and performance analysis have been performed.
