Integration of Maintenance in the Tactical Production Planning Process under Feasibility Constraint

This paper deals with the problem of the joint optimization of the master production schedule and maintenance strategy for a manufacturing system. An efficient production planning and maintenance policy will allow to minimize the impacts of the potential random failures and will let the plan to be feasible. We present a modelisation where we take into account a feasibility constraint; the optimization problem is formulated as a linear program. We propose a heuristic algorithm to solve it and we show the impact of the feasibility constraint on different criteria.
