The performance of dispatching rules tends to be state-dependent, and a rule that performs very well under a given set of shop floor conditions may not necessarily perform as well under different conditions. A new composite dispatching rule that scores jobs based on their priorities under five different dispatching rules is proposed. The score-based dispatching rule is evaluated by means of a comparative...
This paper focuses on the production scheduling problem in a rotor workshop. The scheduling problem is formulated as a reentrant hybrid flow shop problem with non-identical machines in parallel. Some heuristics are developed to solve the problem. The proposed algorithms are compared through various instances that are generated based on real operations in the workshop. Experimental result also reveals...
