摘　　要：过程的复用问题如同软件本身的复用性,具有同样重要的意义.提出了一种支持领域复用的过程元模型.借鉴OO技术中的类继承概念,以表示领域业务过程间的共性以及抽象---特化父子关系;通过参数化模板机制的使用,增强过程的抽象表示能力.据此设计了独立于具体平台的过程定义语言,通过映射机制可转换为特定的过程定义语言如WSFL、WPDL等,从而可被各种工作流引擎执行.实现了过程建模工具PMBuilder.The reusability of business processes is very important feature, just like the reusability of software products. The existing process meta-modals cannot support the process reuse. A process meta-modal is proposed to support domain reuse. Refering the to classt s inheritance technology in the OO, the common character and abstract-reification relation ship among domain business processes are expressed. With the mechanism of parameter template, the abstract expression ability of process modal is strengthened. A platform-independent process definition language is designed based on the meta-modal, it can be convert into specific process definition language by mapping mechanism, such as WSFL,WPDL. Consequently, some workflow engine can execute it and web services can be integrated. A prototype system named ＂PM Builder＂ is realized to build process model by the use of the meta-model and its language.
