针对工作流管理系统在实际应用中面临的过程定义低效、复杂的问题,借鉴软件复用的思想,提出了一种生产线架构下的工作流过程定义复用方法.该方法建立在领域业务本体和工作流模板这两类可复用资产之上,尝试建立特定领域工作流过程定义的复用机制,以提高过程定义的效率.着重探讨了可复用资产的构建、描述和检索等问题.介绍了基于复用的工作流过程定义方法,并开发了相应的实用工具以验证该方法的有效性.%There is a problem in practical application of workflow management system.It is that the workflow processes have been defined with a low efficiency and productivity due to the complexity of actual business processes.An approach to this problem was proposed by adopting the idea and technique of software reuse.The solution is based on the archi-tecture of software product line and aims to improve the efficiency of the domain-specific workflow processes' defini-tion.Two types of reusable assets, domain business ontology and workflow template, were identified.Moreover, how to construct, describe and retrieve these reusable assets was discussed in detail.The steps to define the workflow process based on reuse were explained.As a demonstration,a definition tool was developed and the method was proved feasible and more productive in practice.
