Open shop scheduling problem
WebIn this paper we study various classical Open Shop scheduling problems to minimize the makespan, as well as two modern Open Shop problems. In an open shop, we are presented with mmachines and njobs. Each job is composed of mtasks. The ith task of the jth job requires p ij units of processing to be completed on the ith machine. When m= 2, … WebExperiments have been conducted and computational results show that compared with exact solutions and meta-heuristics, the proposed algorithm can solve the large-size …
