Integer programming approach to production scheduling for make-to-order manufacturing

This paper presents an integer programming approach to production scheduling in make-to-order environment with various due date related performance measures. The proposed formulations incorporate capacity constraints for a hybrid flowshop with multicapacity machines and with batch processing mode. Scheduling of divisible versus indivisible orders are considered. For the proposed integer programming formulations new cutting constraints are identified. Numerical examples modeled after real-world make-to-order assembly system are provided and some computational results with the proposed approach are reported.
