Exact and Heuristic Solution Approaches for a Flexible Job Shop Scheduling Problem Incorporating Machine Operator Restrictions
This paper addresses a flexible job shop scheduling problem with sequence-dependent setup times that incorporates heterogeneous machine operator qualifications. The objective is to minimize the makespan. We present a mixed-integer program and sketch exact and heuristic solution approaches that are based on a decomposition of the problem into a vehicle routing problem and a machine operator assignment problem. The solution methods are analyzed in computational tests. For details, we refer to our full paper.
