中文摘要
      本文考虑用一般标识图模型描述的一类离散事件系统的禁止状态问题.在文［１］基础上，分析了允许控制策略对观测和控制时延的鲁棒性；给出了一步极大允许无冗余反馈控制策略的判据和搜索方法；导出了系统在一个并发活动序列发射后仍保持极大允许性的条件，即对应的并发活动序列的特征.
英文摘要
      This paper concerns the forbidden-state problem for a class of discrete event systems modelled by marked graphs. Based on the framework given in our previous paper[1]，robustness of the permissive control is analyzed for the case in which time delays in control and observation exist. Two approaches are then presented to search and to determine，respectively，the maximally permissive one-step control policy without redundancy. Characteristics are given for the concurrent activities' series whose fires preserve the system being maximally permisive.
