Dynamic management of detected factory events and estimated risks using FMECA

In most of the modern production factories, manufacturing events are capitalized inside the manufacturing information system. To address Overall Equipment Efficiency (OEE), Yield, cost and to reduce actual events impact, action plans are defined by the engineering organization. To secure and manage the action plan process in a preventive way, risk analysis methodology can be used. This paper proposes an approach which establishes a continuous bond between factory events, risk analysis and related action plan with minimal and under control human intervention. A unified management method is proposed. Deployment uses cases from semiconductor industry using the proposed method are shown.
