queuing is analyzed as well as the concept, classification and methodologies of BPR (business process reengineering).
Secondly, the bank businesses are investigated and analyzed. Thirdly, the queuing system of certain bank is
optimized based on BPR by enterprise dynamic simulation. Finally, the simulated results are discussed and the
optimized result is concluded.
