Dynamic Dispatching Control for Elevator Systems

9311776 Cassandras这个提议是对工程学院实习计划的回应。拟议项目的目的是为首席研究员和两名研究生提供与奥的斯电梯公司密切合作的机会，以开发和测试电梯系统的几个动态调度方案。这些是基于PI和他的学生在离散事件动态系统（DEDS）的更广泛背景下进行的研究的新方案。特别地，某些调度控制问题的解是一种最终依赖于一组离散“阈值”参数的形式。提出的一些方案是基于“学习”这些参数的最优值，基于从电梯系统中随时观察到的数据，并通过应用最近开发的随机DEDS在线控制技术。因此，这是一个将为DEDS控制和性能优化开发的一些理论付诸实践的机会，也是一个更好地理解一类DEDS和相关的设计、分析、控制和性能优化问题的机会。根据该倡议的指导方针，奥的斯电梯公司已经承诺提供3万美元（非联邦资金）来支持这项工作，并为该项目指派了一名联合研究员。＊＊＊

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. ***
