Review on unrelated parallel machine scheduling problem with additional resources

This study deals with an unrelated parallel machine scheduling problem additional resources (UPMR). That is one of the important sub-problems in scheduling. UPMR consists a set jobs on machines. In addition to that, number or more are needed. very and its importance comes from wealth applications; they applicable engineering scientific situations manufacturing systems such as industrial robots, nurses, operators, bus drivers, tools, assembly plant machines, fixtures, pallets, electricity, mechanics, dies, automated guided vehicles, fuel, more. The also concern about limitation that dedicated for production process. Therefore, researchers decision makers still working get optimum schedule all instances which have not been obtained this day. able increase profits decrease costs whilst satisfying customers’ needs. research aims review discuss studies related machines resources. Overall, demonstrates criticality resolving problem. Metaheuristic techniques exhibit significant effectiveness generating results surpassing other algorithms. Nevertheless, continued improvement essential satisfy evolving requirements UPMR, subject operational changes based customer demand.
