Abstract
It has been assumed that it is difficult to predict or analyze the performance of the business process by introducing enhanced information systems. Business processes in actuality are too complex and dynamic to understand and analyze the performance with the conventional modeling techniques. In this context, through a case study of applying business process simulation (BPS), an approach is illustrated for predicting the performance of the business process. In addition, it is stressed that the information system should be incorporated into the business process, and BPS model can be suitable to depict BP/IS integration.
