9409691 Sreenivas The research deals with the study of systems whose states have logical or symbolic, rather than numerical values that change with the occurrence of events called Discrete Event Dynamic Systems (DEDS). In this proposal we outline research issues concerning modeling, analysis, control and performance evaluation of DEDS. The supervisory control problem for a broad class of infinite-state DEDS is solvable. This fact can be used to combat the complexity problem in DEDS. This issue is the focus of the modeling and analysis section. The control section addresses an archetypal problem in the control of DEDS, where we propose a novel approach to the elimination of deadlocks. Finally, in the performance section we consider an approach that will permit a system designer to modify, automatically, discrete event simulation programs that only estimate performance so as to efficiently obtain the sensitivity of the performance. This sensitivity information can be used towards system optimization using stochastic approximation techniques. ***

9409691 Sreenivas该研究涉及系统的研究，其状态具有逻辑或符号，而不是随着称为离散事件动态系统（DEDS）的事件发生而变化的数值。 在这个建议中，我们概述了DEDS的建模，分析，控制和性能评估的研究问题。 一类无限状态DEDS的监督控制问题是可解的。 这个事实可以用来解决DEDS中的复杂性问题。 这个问题是建模和分析部分的重点。 控制部分解决了DEDS控制中的一个原型问题，提出了一种消除死锁的新方法。 最后，在性能部分，我们考虑的方法，将允许系统设计者修改，自动，离散事件模拟程序，只估计性能，以便有效地获得性能的灵敏度。 该灵敏度信息可以用于使用随机近似技术的系统优化。 ***
