Abstract
Workflow, to be brief, means the automation of a business processes. A lot of references between workflow models and standards were checked when the authors tried to apply workflow technology to construction projects. The system, originally developed in the BRI's research project, is a tool for supporting the analysis of such reference relationship. The system stores both workflow model written in the IDEF0 and the document structure of the standards in its RDB storage. It enables users to interactively check mutual reference relationship. The authors build an open freeware version of the system, which illustrates four unique demonstrations based on real business workflow models. Users can operate the demos by themselves and efficiently understand the effective-ness of the workflow analysis/plan technology in A/E/C industries.
