Addressed in this paper is a method of integrating a workflow system and si
mulation technology. It is often conceived that workflow systems are a majo
r tool to support BPR. A key to apply the workflow systems to BPR is how to
analyse and evaluate the performance of newly designed processes in advanc
e. A simulation module, called WFSIM, has been developed and interfaced wit
h a workflow system to better support the BPR capability. We demonstrate th
e workability of translating from a workflow model to a simulation language
