时间约束工作流模型及其应用

工作流时间管理是工作流管理系统的一个关键部分,一个工作流程在定义、执行阶段明确计算出其所需消耗的时间以及各个步骤的可能启动时间对于安排时间和资源计划都是很有意义的.本文介绍了时间约束的工作流网及其层次扩展模型,分析目前工作流时间管理中存在的问题,提出时间约束工作流网在事务处理流程和项目管理二种不同应用环境中解决时间计算问题的思路.

The Modeling for Time Restricted Workflow and Its Application

Time Management is a crucial part of the workflow management system. It is significant for us to count how long the whole workflow will take in the defining and executing phase. It is helpful for us to arrange time and resource. The paper introduces the time Restricted workflow net and its layer- extended model. The problems on the time management of the workflow are analyzed in this paper. Finally, the solution of time count problem on the transaction process and the proiect management is presented.
