摘要: Petri 网是基于图形的强有力的建模工具,被用于柔性制造系统调度问题的研究,然而,搜索整个可达树寻找最优调度方案是一个指数倍复杂的问题,由此人们想到利用人工智能算法搜索可达树的一部分获得近优解。该方法被认为是求解调度问题的极具前途的解决方案。从上世纪90年代初期以来,人们对此作了一些卓有成效的研究。本文对这些研究进行归纳总结,为采用该方法求解调度优化问题的研究提供参考。

Abstract: Petri net is a graph-oriented powerful modeling tool and can be used in the study of FMS scheduling problem. However, searching the whole reachability tree for the optimal scheduling is an exponential complexity. Then, artificial intelligence method is proposed to search the RG for optimal or near optimal solution, which is considered a promising method for the scheduling of FMS. From 1990s, much effective effort has been put into that. This paper summarized those studies to do some benefits for the study on this way in the future.
