This paper deals with a production and maintenance problem of manufacturing system under the availability of the machine and subcontracting constraints. We have developed an integrated production/maintenance policy for a manufacturing system satisfying a random demand by using a subcontracting machine. In order to ensure a simultaneous economic production planning with an optimal maintenance strategy, a joint optimization is made in order to minimize the total cost of production, holding, subcontracting and maintenance costs. An analytical study and a numerical example are presented to prove the developed approach.
