  Today, a competitive manufacturing environment imposes further production
cost reduction on modern companies. Seeking proper recommendations in
production and maintenance planning are the two essential cornerstones of
effective production organizations. In the current research, we have considered
the problem of integrated multi-product process and maintenance planning on a
capacitated machine that is susceptible to random breakdown. Maintenance
processes comprise general perfect repair (non-cyclical) as preventive
maintenance (PM) in the early stages and minimal repair as corrective
maintenance for the occurrence of machine breakdown. Furthermore, a rational
presumption is reflected in the problem statement in which the time and cost of
PM are pertinent to the interval between the prior perfect repair and current
PM. The purpose served by this paper is to minimize the cost of production
accompanying PM, and the expected corrective repair, consequently, a
mixed-integer linear programming (MILP) model has been constructed to pave the
way. The model investigated under two circumstances of the machine age effect
and its absence. The outcome depicted that the presence of the machine age
effect led to an accurate and lessen total cost calculation.
