Abstract

With the rise of industry 4.0 and the establishment of intelligent factories, how to use artificial intelligence algorithm to solve flexible job shop scheduling problem (FJSP) is one of the hot research. FJSP is proved to be a NP-hard problem with a large solution space. Compared with the job-shop scheduling problem (JSP), FJSP should not only know the processing time of the workpiece process, but also need the machine to optimize the objective function. Therefore, this paper considers the maximum completion time as the objective function, and proposes a deep reinforcement learning (DRL) algorithm to solve FJSP. Compared with heuristic rule and genetic algorithm, the numerical results show that DRL algorithm has better searching ability and better effect in solving FJSP problem, which provides a new idea for solving shop scheduling problem by artificial intelligence algorithm.
基于深度强化学习的柔性作业车间调度
随着工业4.0的兴起和智能工厂的建立,如何利用人工智能算法解决柔性作业车间调度问题(FJSP)成为研究的热点之一。证明了FJSP是一个具有大解空间的np困难问题。与作业车间调度问题(JSP)相比,车间调度问题(FJSP)不仅要知道工件的加工时间,而且需要机器进行优化的目标函数。因此,本文以最大完成时间为目标函数,提出了一种深度强化学习(DRL)算法来求解FJSP。数值结果表明,与启发式规则和遗传算法相比,DRL算法在求解FJSP问题时具有更好的搜索能力和效果,为人工智能算法求解车间调度问题提供了新的思路。
