中文摘要： 随着系统结构和任务目标的复杂化，传统的命令控制（Command & Control）分析和合成技术将不能适应，不优化的命令和控制将会产生严重的后果，至少也会浪费大量的资源。离散事件系统的智能控制研究是以系统内在结构为基础，以运行的任务目标为导向，以量化的测度来实现命令控制的最优化。目前基于语言测度的离散事件控制分析和合成理论与应用已经收到了良好的效果，但是还有很多亟待解决的地方，例如（1）开环模型需要规范化以实现可控事件和非可控事件的完全分离；（2）以概率相关的可控事件活度需要随着控制器进行变化，（3）在实际应用中应该采用自适应算法对非可控事件的活度进行调节，从而保障最优控制器也跟着适应。上述这些改进将对已有的以语言测度为基础的离散事件控制技术产生重大改进。另外我们将把离散系统应用于机器人物流控制来展示离散系统控制技术应用的必要性，同时验证新的理论和算法的正确性。

英文摘要： As system structures and mission objectives become more and more complex, the traditional technology of Command & Control analysis and synthesis may not have acceptable performance. Non-optimal command and control may have severe consequences or waste huge quantities of resources to say the least. The research on intelligence control of Discrete Event System is based on the system internal structure and oriented by the mission objective, and it uses the quantified language measure to achieve the optimality of command and control. Presently, based on language measure, the analysis and synthesis theories and applications of discrete event system control have been promising, however there are still quite a few imminent improvements to be made, for example: (1)open loop modeling needs to be regulated in order to completely separate controllable events from uncontrollable events; (2)the probability related Event Cost of controllable event needs to change with different controller; (3)in application the event cost of uncontrollable events should be adjusted by some adaptive algorithm according to updated information of observation, and as a result the optimal controller will be upgraded accordingly. The above mentioned improvements will have significant impact on existing discrete event control techniques that are based on language measure. In addition, we will apply the improved discrete event system control theories to robot logistic management in order to prove the newly developed theories and algorithms and also to demonstrate the importance and necessity of applying discrete event system control technology.
