在自动化制造系统（AMS）中，阻塞和死锁是不希望出现的。因此，解决这些问题是必不可少的，以确保顺利生产演变通过系统的监督控制。如果AMS包含可能意外故障的不可靠资源，则情况复杂，问题变得具有挑战性。本文从资源配置的管理和控制的角度研究了对这类AMS的鲁棒监管。本研究的最终目标是开发一个控制器来分配缓冲区空间，这样任何故障都不会通过阻塞传播到系统的其他部分。换句话说，必须始终保证不需要任何故障资源的每种零件类型的连续生产。我们提出了一个监督控制策略，满足上述所需的属性，使用自动机和Petri网的形式化工具。该政策放宽了在以前的工作中，每一个部分类型需要在预定义的生产路线中最多一个容易发生故障的资源的假设。同时，策略的执行和实施不需要任何中央缓冲区。我们还提出了一个调查和一些比较研究的各种方法在文献中的鲁棒监督的死锁解决AMS。
Blockage and deadlock are undesirable in an automated manufacturing system (AMS). Thus, addressing these issues is essential to ensure smooth production evolution via system supervisory control. If an AMS contains unreliable resources which may break down unexpectedly, then the situation is complicated and problems become challenging. This work investigates the robust supervision for such AMSs from the perspective of management and control of resource allocation. The ultimate goal of this study is to develop a controller for allocating buffer space, such that any failure does not propagate through blocking to stall the rest of the system. In other words, the continual production of every part type not requiring any of the failed resources must be guaranteed at all time. We propose a supervisory control policy that satisfies the above desired property by using formal tools of automata and Petri nets. The policy relaxes the assumption made in previous work that each part type requires at most one failure-prone resource in the predefined production route. Meanwhile, the policy execution and implementation do not need any central buffers. We also present a survey and some comparative studies of various approaches in the literature about robust supervision for deadlock resolution in AMSs.
