RIA: Modeling, Analysis, Control and Performance Evaluation of Discrete Event Dynamic Systems

[409691] Sreenivas该研究涉及的系统，其状态具有逻辑或符号，而不是随事件发生而变化的数值，称为离散事件动态系统（DEDS）。在本提案中，我们概述了在DEDS建模、分析、控制和性能评估方面的研究问题。求解了一类广义的无限状态DEDS的监督控制问题。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，我们提出了一种消除死锁的新方法。最后，在性能部分，我们考虑了一种方法，该方法允许系统设计人员自动修改仅估计性能的离散事件模拟程序，以便有效地获得性能的灵敏度。该灵敏度信息可用于使用随机逼近技术进行系统优化。＊＊＊

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. ***
