There are a number of operations to be processed on parallel machines. Each operation requires a set of tools; however, the number of available tools are limited. Our objective is to minimize the makespan, i.e. the completion time of the final operation. We propose two different mathematical programming models for this problem. Since the problem is strongly NP hard in general, finding the optimal solution requires extremely long computational times as the problem size increases. We therefore develop a tabu search algorithm in order to find near-optimal solutions within reasonable times. (C) 2016 Elsevier Inc.
