摘　　要：通过对带阈PERT图的审批工作流引擎研究与开发,为信息系统中的审批流程控制提供了一个轻量级的运行时和配置工具。在给出带阈PERT图定义的基础上,研究了审批节点的可达性,为引擎开发提供算法依据,同时对审批实体进行了状态分析,从而设计并实现了引擎的运行时,编程接口和配置文件。基于20种工作流模式,对模型的需求适应性进行了测度分析,并通过多个信息系统的应用实践,表明了该引擎运行的稳定性,可配置性和适应性。The auditing workflow engine is developed based on the research of PERT diagram with threshold, a light runtime and configuration tool is provided for the auditing controlling in some information systems. Through studying the reachable of auditing nodes based on the definition of PERT diagram with threshold, the basis of the engine development is established. Over the status analysis of audited entities, the runtime, application programming interface and configuration file is designed and implemented. According to the 20 workflow patterns, the measure analysis is given to the requirement adjustability. It is proven that the stability, configuration capability and adjustability of the engine by the application in several information systems.
