Objective: In the purchasing process of medical material, it is important that the proper design of each part concerned as well as the optimization and allocation of suitable resources for the model be solved. Methods:Based on the structure and formal definition and process modeling of Petri net, the modeling is established for the mapping from the route mode of workflow to Petri net. Results:Moreover, a rationality validation algorithm for the workflow and a workflow optimization algorithm are proposed. Conclusion: The results indicate that this method is brief and direct in modeling and analyzing of workflow, which will also provide theoretical support for the development of a purchasing software system.%目的：在医用材料采购过程中合理设计、优化其各个环节，合理解决采购流程工作流建模所需要的资源配置问题。方法：在对当前工作流中的主要路由模型分析的基础上，结合Petri网的结构、形式化定义和流程建模方法，建立从工作流到Petri网的路由映射模型。结果：采用基于Petri网的工作流技术对医用材料采购流程进行工作流建模，并提出了一种工作流合理性验证算法和工作流的优化算法。结论：基于Petri网的工作流建模方法具有直观、简洁及实用等优点，可为医用材料采购软件的开发提供很好的理论支持。
