On Scheduling of Flexible Manufacturing Systems Wu Xiqi;Lou Tong (Prof., Dept .of Electric Automation, WUT,Wuhan 430070,China.) Serveying defferent scheduling methods existing, a scheduling technique for flexible manfacturing systens is realized which is based on the combination of simulation technique,prior-rule scheduling and expert system.The factors which will have effects on scheduling have been discussed.The criterion for evaluation of scheduling efficiency, the prior scheduling rules and the scheduling model have been set. Some experiment results are given.:FMS;scheduling;expert system
