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 Bill's research project, is a tool for supporting the analysis of such reference relationship. The system stores both workflow model written in the IDEFO and the document structure of the standards in its RDB storage. It enables users to interactively check mutual reference relationship. The system may be used in wide-range field, for instance, as a newcomer's teaching materials in OJT, as a tool for the adjustment check and the optimization of your domain workflow models, and so on.
