9311776 Cassandras This proposal is in response to the Engineering Faculty Internship Initiative. The objective of the proposed project is to provide the opportunity for the Principal Investigator and two graduate students to closely work with the OTIS Elevator Company, in order to develop and test several dynamic dispatching schemes for elevator systems. These are novel schemes based on research carried out by the PI and his students in the broader context of Discrete Event Dynamic Systems (DEDS). In particular, the solution to some dispatching control problems is of a form which ultimately depends on a set of discrete "threshold" parameters. Some of the proposed schemes are based on "learning" the optimal values of these parameters, based on readily observed data from an elevator system and by applying techniques recently developed for the on-line control of stochastic DEDS. Thus, this is an opportunity to put some theory developed for DEDS control and performance optimization to the test, as well as to gain a better understanding of a class of DEDS and related problems of design, analysis, control, and performance optimization. In accordance with the guidelines of this Initiative, the OTIS Elevator Company has already made a commitment of $30,000 (non-federal funds) to support this effort and has assigned a co-investigator for the project. ***

9311776 Cassandras本提案是对工程学院实习计划的回应。 该项目的目的是为主要研究者和两名研究生提供与奥蒂斯电梯公司密切合作的机会，以开发和测试电梯系统的几种动态调度方案。 这些都是基于PI和他的学生在更广泛的离散事件动态系统（DEDS）背景下进行的研究的新方案。 特别是，某些调度控制问题的解最终取决于一组离散的“阈值”参数。 一些建议的计划是基于“学习”这些参数的最佳值，从电梯系统的基础上容易观察到的数据，并通过应用最近开发的随机DEDS的在线控制技术。 因此，这是一个机会，把一些理论开发的DEDS控制和性能优化的测试，以及获得更好的理解一类DEDS和相关的问题的设计，分析，控制和性能优化。 根据该倡议的指导方针，奥蒂斯电梯公司已经承诺提供30 000美元（非联邦基金）来支持这一努力，并为该项目指定了一名共同调查员。 ***
