Abstract: Aiming at the distributed flexible job shop scheduling problem (DFJSP) with minimizing makespan, a hybrid shuffled frog-leaping algorithm (HSFLA) is proposed. In this algorithm, the encoding adopts the scheme of partial solution space based on the operation and factory sequences, and the machine selection is determined in the decoding process with a rule. A variable neighborhood search (VNS) algorithm is introduced to improve the local search ability of HSFLA. To make up for the shortcoming that the partial space encoding method cannot search the full solution space, a tabu search algorithm of full solution space is introduced in critical factory to expand the solution space and further improve the local search ability of HSFLA. By solving benchmark instances and comparing HSFLA with the existing state-of-the-art algorithms, the effectiveness and superiority of HSFLA are proved.
