Webflow shop问题，n个工件在m台机器上加工，每个工件都要在m台机器上加工一次，并且每台机器上的工序，即加工顺序都是一样的。如四个工件在第一台机器加工顺序为2134，那么在剩余m-1台机器上的工序必须严格保持2134的顺序。因此flow shop也被称为流水作业或顺序作业。而对于job shop，每台机器的工序是可变的。因此job shop也被称为异序作业 … The simplest form of the offline makespan minimisation problem deals with atomic jobs, that is, jobs that are not subdivided into multiple operations. It is equivalent to packing a number of items of various different sizes into a fixed number of bins, such that the maximum bin size needed is as small as possible. (If instead the number of bins is to be minimised, and the bin size is fixed, the problem becomes a different problem, known as the bin packing problem.)
