摘要
随着工作流技术在企业业务流程管理中的广泛应用,人们对工作流管理系统的描述能力和动态变更能力提出了更高的要求。针对目前的工作流过程定义方法在这两个方面的不足,本文提出了一种基于模板机制的工作流过程定义方法。该方法在现有的工作流过程定义模型的基础上,加入了新的过程模板和活动接口元素。本文由此扩展了工作流过程定义语言,增加了支持模板描述的机制。实际应用的结果表明,该方法和现有的工作流过程定义方法相比,显著提高了模型描述能力,使得过程模型具有了较强的可重用性和可扩展性,并具备了一定的动态变更能力。
The technique of workflow is widely used in the domain of enterprise business process management,while the higher ability of describing and the ability of dynamic changing are required to the workflow management system. In order to solve the problem of lacking these two abilities in the existing workflow process definition method,an im- proved workflow process definition method based on template mechanism is put forward in this paper. This proposed method extends the existing workflow process definition model and workflow process definition language by adding new modelling elements,such as process template and activity template. The result of the application of the proposed method shows that compared with the existing method,it significantly improves description ability,enhances model reusability and expandability and introduces the ability of dynamic changing.
