Abstract
The technology of plant maintenance is to be systematized into technology standard, and its comprehensiveness and consistency are necessary for the risk based maintenance. To generate such engineering standard for plant maintenance, the requirement of technology standard for plant maintenance should be specified on the basis of business process model which consists of PDCA (Plan, Do, Check, Action) cycle, and a framework to provide technology standard fit to the requirement is necessary. We have developed a business process model for plant maintenance and defined requirements for its technology standard. We are developing IDEF0 business process model to generate comprehensive and consistent engineering standard.
