Abstract: From a logistical point of view,there are many similarities between administrative processes and production processes.In this paper,we apply BOM and Petri-net technologies to workflow process,and construct the logic concept of workflow model.The implementation algorithm of mapping the BOM onto Petri-nets is also introduced.The dynamic adjustment of model is also discussed.At last,the instance simulation based on the mapping algorithm is introduced.

Key words: BOM, Petri-nets, workflow, modeling, optimization
