基于XPDL的过程模式研究

Research of Process Patterns Based on XPDL

通过扩充XPDL语言的语义,建立了一种过程模式的描述技术。对XPDL语义的扩充包括定义产品和资源、定义过程模式、实现描述过程模式的模板、实现描述活动的模板和定义实体的图形化语义等工作。文章对这几个方面的内容进行了描述。

A formal description of process patterns is established in this paper by extending the semantics of the XPDL language. To describe a process pattern comprehensively, products and resources referred to by the pattern must be defined, an explicit template of process patterns as well as of activities must be given, and a graphical representation of process patterns is also practically needed to enhance the expressiveness of this method. These various facets necessary for presenting a process pattern are explored in this paper.
