Abstract：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 achievements in understanding deadlock issues in automated manufacturing systems(AMSs);nevertheless,most of the deadlock avoid-ance 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.
