BPR is a thorough rebuilding of business process. BPR focus on improving on many aspects like cost,
quality, service, speed, etc. [2] According to the difference of range of process and characteristic of
reengineering, BPR can be divided into three parts---BPR within the function, BPR among the functions
and the BPR among organizations [3]. We need scientific method and tools to study on the reengineering
of process. Based on the results of former research, methods of BPR can be divided into four categories:
method based on analysis of results, method based on analysis of technique, method based on eliminating
of activities, method based on agent standard. This study mainly focus on the application of BPR in the
bank queuing system, discovery of bottleneck and optimization based on simulation.
