워크플로우 관리 시스템 기반의 FRACAS 프로세스 개발

Failure reporting, analysis, and corrective action system (FRACAS) is a closed-loop procedure for analysis and correction of root failure causes of system, product or service. In this study, we use workflow management system (WfMS) for developing and implementing FRACAS process. WfMS authorizes failure engineers to manage their processes in addition to providing fundamental FRACAS functions such as document management, failure reporting and failure analysis. On the basis of WfMS, failure engineers can design FRACAS processes with process designer, and the processes can be modified and customized. WfMS also makes a role of framework for integrating failure analysis system and database management system. We develop prototype FRACAS process using open-source WfMS to represent that proposed methodology is improved in terms of system functionality and extensibility.
