An integrated optimization model of production plan and scheduling is introduced. Function objective is to minimize sum of total setup cost (initial setup cost and related setup cost), stock cost, production cost and overtime cost. Restraint functions include equilibrium stock, production capacity, as while as scheduling restraints (procedure restriction and machine capacity restriction). Feasible plan can be set down with considering scheduling restraints.
