中文摘要：

构建一个高效、精简、优质的医疗服务流程是医院高效、低成本和高质量运营的基础。针对目前医疗服务缺乏定量化的分析评价手段，提出了采用赋时层次有色Petri网（HTCP-net）来建模乖优化医院当前的医疗服务流程。应用建模、仿真工具CPNTools对医疗服务流程进行建模和仿真分析，从而得到患者平均等待时间、各类资源利用率等医院的外部和内部性能指标，最后在此基础之上通过合并任务、整合资源等流程重组和优化方法实现了医院服务效率的提高和服务质量的改进。

英文摘要：

An optimized streamline medical treatment process is the key to operate a hospital efficiently and effectively. An approach of modeling and optimizing the medical treatment process was proposed using the Hierarchical Timed Coloured Petri net （HTCP-net）. Founded on the HTCP-net based medical treatment process model, CPN Tools, a Hierarchical gimed Coloured Petri net simulation tool, was adopted to evaluate the outer and inner performances of hospitals, such as patients＇ average waiting time and resource utilization. According to the results, the service efficiency and service quality of hospitals could be improved by applying the methods of process redesign and optimization like combining tasks and integrating resources.
