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.
