Abstract
In this article we study the dynamics of business processes and interactions between business units in an enterprise, and to this end, we developed a framework for enterprise modeling using the process hierarchy approach. We developed and implemented a multiagent information system (MAIS) for the supply chain network for capturing both the structure and the processes of an enterprise. The MAIS is implemented on the Swarm simulation platform and models the order fulfillment process (OFP) as one of the core tasks of supply chain networks. In addition to modeling the interactions in the OFP, the MAIS is also used as a simulation testbed to experiment with different strategies to improve the performance of the OFP.
