摘要
本文研究离散加工系统中异步并发活动的控制与协调问题．系统采用具有外部输入位置的受控标识图描述．通过对外部输入位置中令牌数目的控制，使系统不进入禁止状态集，同时具有最大限度的柔性．系统的逻辑行为用极小代数描述，并由此得到一步允许无冗余控制策略．
This paper concerns the control and coordination of concurrent asynchronous activities in discrete manufacturing systems. The system is modeled by controlled marked graph with external input places.The number of tokens in each external place is controlled to guarantee that the forbidden states will not occur. Logical behavior of the system is described by min algebra and one-step permissive control policy withoutredundancy is obtained.
