The rapid development of new manufacturing modes such as intelligent manufacturing and network manufacturing has brought new opportunities and challenges to the promotion of distributed production mode.At present,domestic and foreign schol-ars have summarized and analyzed the problems of flexible job-shop scheduling and distributed job-shop scheduling,but there is still a lack of overview of distributed flow shop scheduling.Taking distributed flow shop as the research object,it summarizes the existing research results from the aspects of operation mode analysis,optimization target design,special constraint characteriza-tion,model solving methods and engineering applications,and prospects the future research direction of distributed flow shop scheduling.
