摘　　要：随着科学技术的快速发展,制造自动化在制造工厂已经成为一个主流方向.在过去的几十年中,研究人员已经对自动制造系统的死锁问题做了大量的研究.但是大多数解决方案总是假设分配的资源不会故障.然而,任何一个制造研究者都知道,资源故障来自各种各样的原因,包括工件破损、传感器故障、零件缺失和电器失灵等.显然,一旦资源发生故障,后续加工路径中需要使用这个故障资源的进程将停滞,不能完成其加工生产,直到故障资源被修复.那些不使用故障资源的支路也会被发生停滞的进程所阻塞.最坏的情况就是一个简单的资源故障可能会导致整个系统的崩溃.因此,制造系统中的资源故障问题急需解决.通过分析大量的文献资料,本文对解决死锁和阻塞问题的控制方法做了系统的总结研究.同时,对本文提出的稳健无死锁控制策略以及亟待开展的研究工作做了详细的介绍.With the quick development of science and technology,manufacturing automation plays a role of mainstay for the construction of manufacturing industries.Over the past decades,researchers have made tremendous achievementsin understanding deadlock issues in automated manufacturing systems(AMSs);nevertheless,most of the deadlock avoidance or prevention methods have assumed that allocated resources never fail.In reality,as any practicing manufacturing researcher knows,resource failures derive from all kinds of causes,including tool breakages,sensor faults,part defects,component malfunctions,etc.Obviously,in case a resource fails undesirably,a process requiring the failed resource in its remaining route definitely cannot be accomplished unless the resource recovers.Moreover,a process not necessarily requiring the failed resource can be blocked innocently by this process.In the worst case,a single resource failure may paralyze the entire system.Therefore,resource failures in automated manufacturing systems need to be resolved forwardly.By surveying a large number of literatures,this paper summarizes the existing control approaches to resolving deadlock and blocking issues.Moreover,based on the reviews,our current and future research trends are pointed out in detail.
