A mixed-integer programming model for planning over-time in the Final Quality Control Department at the T-shirt manufacturing facility of Ozkok Textile, Inc. has been developed containing 0-1 binary variables. This model partitions time into a number of periods. Therefore, it is a multiperiod planning model with the objective of minimizing final quality control cost for the next three periods. The model will enable management to plan for the upcoming season that is composed of three months by providing them with staffing level, quantity of each product type that will be final inspected in-house in regular and over-time and will be subcontracted to be inspected due to inadequate capacity in each period. Management can also create many different scenarios and see how the optimum solution will might lead to improvements in the Final Quality Control Department.
