In　view　of　current　technical　level　of　China＇s　manufacturing　industry　which　needs　to　be　improved　in　a　long　run,　reasonable　job　shop　scheduling　(JSS)　is　an　important　measure　to　improve　production　efficiency　at　present.　To　this　end,　this　paper　summarizes　the　classification　and　existing　problems　of　JSS　problems.　The　results　show　that　based　on　current　status　of　multi-process　pipeline　batch-mixed　production,　new　requirements　have　been　put　forward　for　the　JSS　study.　Besides,　a　JSS　model　of　multi-process　pipeline　was　established,　and　the　case　analysis　shows　that　the　optimization　effect　of　this　model　is　superior　to　the　traditional　model;　the　JJS　model　of　batch-mixed　production　was　established,　and　the　batch　and　non-batch　schemes　were　discussed　in　the　case　analysis.　Finally,　it’s　found　that　the　batch-based　scheduling　can　greatly　improve　production　efficiency.　This　study　can　provide　some　reference　and　suggestions　for　the　production　and　practice　of　manufacturing　enterprises.　©　2019　Editura　Politechnica.　All　rights　reserved.
