Concurrent scheduling of a job shop and microgrid to minimize energy costs under due date constraints

Energy Conscious Production Scheduling is a developing field. This paper proposes a MILP formulation that allows for the concurrent scheduling of energy supply and job processes with the aim of minimizing energy cost while guaranteeing due dates. The energy system includes TOU grid pricing, dispatchable generators, an electrical storage system and a solar array. This was compared to a base case of makespan minimization and the potential cost savings are quantified.
