An hybrid CP/MILP method for scheduling with energy costs

Abstract

This paper deals with energy-related job scheduling for a foundry, in order to minimize the electricity bill. Accounting for energy and human resource constraints leads to better solutions in terms of cost and overall energy consumption. We propose a hybrid heuristic based on a two-step constraint/mathematical programming approach that improves significantly the computation time, compared to the full MILP model.
