No-wait job-shop scheduling (NWJSS) problem is one of the classical scheduling problems that exist on many kinds of industry with no-wait constraint, such as metal working, plastic, chemical, and food industries. Several methods have been proposed to solve this problem, both exact (i.e. integer programming) and metaheuristic methods. Cross entropy (CE), as(More)
This paper combines the differential evolution algorithm (DE) with bottleneck heuristic for two-objective minimization makespan and total tardiness on a hybrid flow shop scheduling with unrelated parallel machines (HFSUPM). In this model, some machines at each stage are not identical (unrelated parallel machines) and have different processing time. This(More)
