这个领域最困难的问题之一是作业车间调度问题(Job-shop Scheduling Problem, JSP),该问题中,一组机器需处理一组工件,每个工件由一系列具有先后顺序约束的工序形成,每个工序只需要一台机器,机器一直可用,可以一次处理一个操作而不会中断。决策内容包括如何对机器上的工序进行排序,已优化给定的性能指标。JSP的典型性能指标...
(Flexible Job-shop Scheduling Problem, 简称为FJSP) 是经典JSP的拓展 !!! 它与JSP最大的不同在于 FJSP允许每个工序在任何一台机器上面进行加工 除了需要对工序进行排序外 还需要决策加工该工序的机器 因此FJSP更加复杂 本文将为大家简单介绍一下FJSP问题 以及该问题在学术文献中的经典算例及其求解结果 问题简介 问...
