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
Cost Effect also makes the problem paid little attention. The level of management of our country’s banks 
is low. Lacking of outside competition leads to improper classification of customers, lopsided business 
process, improper staffing, etc. The custom of paying needs time to be changed completely. Return on 
investment of ATM is relatively low. Therefore, we should not anchor our hope on the increasing of 
branch bank, change of custom of paying, popularization of electronic bank to solve the problem of bank 
queuing. Thus, we must focus on improving the queuing system of bank.
