Risks analyses update based on maintenance events

This paper will focus on the management and improvement of equipment availability with better prevention of failures. It is focused on one of process control tasks: preliminary risks analysis. The result from this study is a method which empowered engineers and managers decision about actions to implement regarding negative events in their manufacture. The article proposes a risk based maintenance method, which relies on the regular and automatic update of equipments’ risk analyses including equipment failure history. The associated aided decision tool is presented. The article is structured in four parts. After a risk management domain literature overview, the paper presents the new risk based maintenance method. A case study in semiconductor industry shows that FMECA can be employed in a dynamic way for managing maintenance activities. The alternative model simplifies and makes more reliable risks identification and estimation. Results and a short discussion end the article
