摘　　要：为了解决工作流业务执行过程中的随机性,提出了基于GERT网络的工作流动态调整引擎的设计方法。介绍了海基数据管理系统和信号流图,探讨了GERT网络解析算法原理,针对发文处理流程,通过海基数据管理系统有效地跟踪发文流程的执行,建立了GERT网络模型进行了求解得到流程执行过程中耗时的范围,最后根据结果由系统管理员设置干预时间来实时的监控和管理工作流。按照实际运行时流程状态重新设计或修改流程定义,实验结果表明了该设计可以有效提高了业务流程的柔性、动态扩展和自动化程度。To solve the randomness in workflow process execution,a design method of the dynamic adjustment workflow engine based on GERT net is presented.First the hikey data management system and signal flow graph is introduced,then the analytical algorithm principle of the GERT network is investigated,and according to the issuing documents deal process in shanghai association for science and technology,the implementation of the issuing documents is effectively tracked by hikey data management system,a GERT network model is established in order to solve time-consuming scope in workflow process execution.Finally according to the results,the system administrator is allowed to set intervention time to monitoring and management the workflow at real time.By redesign or modify the pro-cess definition in the light of actual conditions,the presented method is demonstrated that can effectively improve the flexibility,dynamic extension and high degree automation of business process.
