1 ‘ODDS ALGORITHM’-BASED OPPORTUNITY-TRIGGERED PREVENTIVE MAINTENANCE WITH PRODUCTION POLICY

Abstract: In the field of manufacturing, the planning of opportunistic preventive maintenance actions adapted to minimise the number of unnecessary interruptions to production remains a major industrial challenge. Indeed, maintenance decisions have to be made in synchronisation with the production demands to eliminate costly unscheduled maintenance shutdowns and to improve productivity as well as quality. To confront this issue, this paper proposes an innovative approach based on the ‘odds algorithm’. The objective is to select, among all the production stoppages already planned, those which will be optimal to develop maintenance actions in time according to the degraded system state. The optimisation phase incorporates criteria such as reliability, maintainability and the duration of production stoppages. The feasibility of the approach is shown in a sample case
