摘要: 工作流技术重点关注如何将已经抽象的企业业务模型描述成计算机可理解和自动处理的流程及其自动处理所需要的各种资源或条件,而并不关心如何对业务进行抽象才能最恰当地反映企业的实际需要.针对此问题,提出了一套通用的点线面一体化业务分析概念模型,即PLS模型(Point-Line-Surface Conceptual Model),定义了用PLS模型分析系统所涉及的各种元素,并分析了PLS模型元素和EPC(Event-driven Process Chains)元素间的映射关系,从而通过PLS构建的系统可以用EPC描述.为验证模型的实用性,以南水北调中线干线工程建设管理信息系统为例,详细阐述了如何利用PLS模型分析企业业务并用EPC描述.

Abstract: Workflow technology, which plays a more and more important role in enterprise information systems, mainly concerns the translation of business models into processes that can be understood and automatically dealt with by computer systems. A prerequisite for applying workflow technology is to effectively analyze enterprise business. As a result, how to analyze and model enterprise business is a fundamental problem in enterprise information systems design. There isn′t yet any universal approach to performing this critical task, and it′s usually done in an ad hoc way. On this ground, the point-line-surface(PLS) conceptual model as a universal approach was proposed to analyze enterprise business. The entities PLS includes were defined and the mapping betweenPLS entities and EPC entities was illustrated. The enforcement of PLS model and its EPC description are demonstrated by our experience in the construction management information system for south-to-north water diversion middle route project.
