An Optimization Approach to Solve a Multi-Objective Unrelated Parallel Machine Scheduling Problem

In this study, a multi-objective optimization method for an unrelated parallel machine scheduling problem was addressed. The model, simultaneously takes into account the minimization of makespan and machine utilization cost. Then, because of the complexity of the problem, a heuristic algorithm will be developed to solve the mathematical model. To show the validity of the model, and also solution approach, a case will be randomly generated, and solved by the heuristic algorithm and also Lingo optimization software. The results show the validity of the model and also solution approach.
