Integrated Production-Delivery Lot Sizing Model with Limited Production Capacity and Transportation Cost considering Overtime Work and Maintenance Time

الملخص EN

An extension of the integrated production-delivery lot sizing model with limited production capacity and transportation cost is investigated.

We introduce the factor of overtime work into the model to improve the manufacturer’s production.

In addition, when finishing a lot, the manufacturer has maintenance time to maintain and repair equipment for ensuring that the supply chain is operating continuously.

By analyzing the integrated model, the solution procedure is provided to determine the optimal delivery and order policy.

We conduct a numerical experiment and give sensitive analysis by varying some parameters to illustrate the problem and its solution procedure.
