摘要
为定量分析口岸通关效率,以口岸通关流程为研究对象,建立基于分层赋时Petri网建模方法(HTPN)的口岸通关流程模型.模型中包含经验时间参数,可根据不同的时间参数分布,对模型进行定量分析.应用W itness软件,对所建模型进行仿真和口岸通关流程效率分析.仿真结果验证HTPN模型的正确性,可为现有流程的优化重组提供评估手段,给决策者提供决策依据.
In order to analyze efficiency of the customs clearance quantificationally, taking business process of the customs clearance as researching subject, a model about the business process of the customs clearance is establised based on the hierarchically time Petri net （HTPN）. The model is analyzed quantificationally according to the different time parameter distributions. By the help of Witness, the model is simulated and the efficiency of the business process of the customs clearance is analyzed. Simulation shows the model is correct, and it may provide an appraisal method for optimizing the reorganization of the existing flow and the policy-making basis to the policy-maker.
