Using Heuristic and Branch and Bound Methods to Solve a Multi-Criteria Machine Scheduling Problem


In this paper, we investigate some methods to solve one of the multi-criteriamachine scheduling problems. The discussed problem is the total completion timeand the total earliness jobs To solve this problem, some heuristicmethods are proposed which provided good results. The Branch and Bound (BAB)method is applied with new suggested upper and lower bounds to solve thediscussed problem, which produced exact results for in a reasonable time.
