Energy Contract Optimization for the Single Item Lot Sizing Problem in a Flow-Shop Configuration and Multiple Energy Sources

摘要

In this paper, a new single item lot sizing problem, including different energy sources is addressed. The objective is to determine the optimal production planning and energy contract which minimize production and energy costs with respect to constraints of production systems and energy supplier contract conditions. Two types of energy sources (traditional and renewable) are considered. The choice of energy contract value is also addressed in terms of capacity. The proposed model is explained and illustrated with numerical examples. Computational results are exposed to evaluate the proposed model.
