NSF/CONACyT: Bi-National Effort on Distributed Manufacturing Supervisory Control Systems

这项NSF/CONACyT拨款为德克萨斯大学阿灵顿分校（UTA）提供资金，与瓜达拉哈拉IPN Unidad Guadalajara（CINVESTAV）和华雷斯城自治大学（UACJ）合作，在柔性制造系统（FMS）控制和通过互联网实施新型离散事件（DE）监督控制器方面开展合作研究。 通过结合现有的研究成果并通过联合研究开发新的研究成果，本研究将开发一种FMS设计、决策和在线监督DE控制的综合方法。1）用于制造系统的DE监控控制器的结构和性能，使用UTA的基于矩阵的离散事件控制器作为工具，制造系统的监督控制器的层次设计，并改善调度，路由和部分释放;研究瓶颈和最佳动态再平衡的工作，以减轻瓶颈;设计，并研究的性能和复杂性，分布式分散的监督控制器，多个网络化的单元制造工作单元;和2）通过在UTA为来自美国和墨西哥的本科生和研究生提供关于DE控制器分析和设计的正式培训的暑期课程，提高学术和更广泛的影响目标;让当地高中生参与实际制造和机器人系统的课程项目;共同为墨西哥博士提供建议。该项目包括访问UTA进行研究和开发;设计和开发基于互联网的生产工作单元监控系统;以及通过互联网建立远程学习计划，培训墨西哥学生对工作单元进行编程。 此外，本研究将通过为工业合作伙伴设计飞机零件的化学处理流水线，设计用于零件路由和资源分配的DE监督控制器，并模拟零件路由和资源分配的各种策略，来实现工业合作伙伴化学流水线。 自动化、动态控制的化学品流路是飞机制造中的一个新概念，有可能在新行业中获得显著的市场份额。

This NSF/CONACyT grant provides funding for the University of Texas at Arlington (UTA) to work with the Centro de Investigaciones y de Estudios Avanzados del IPN Unidad Guadalajara (CINVESTAV) and the Universidad Autonoma de Ciudad Juarez (UACJ) to carry out collaborative research in Flexible Manufacturing Systems (FMS) control and implementation of novel Discrete Event (DE) Supervisory Controllers over the internet. By combining current results and developing new results by joint research, this research will develop an integrated approach to FMS design, decision-making, and on-line supervisory DE control.There are two goals in this NSF/CONACyT research: 1) Structure and performance of DE supervisory controllers for manufacturing systems using UTA's patented matrix-based discrete event controller as a tool to perform high-level design of supervisory controllers for manufacturing systems and improve dispatching, routing, and part release; study bottlenecks and optimal dynamic rebalancing of jobs to alleviate bottlenecks; design, and study the performance and complexity of, distributed decentralized supervisory controllers for multiple networked cellular manufacturing workcells; and 2) improve academic and broader impact goals by offering a summer course at UTA for formal training on the analysis and design of DE controllers for undergraduate and graduate students from USA and Mexico; involve local high school students in course projects on actual manufacturing and robotic systems; jointly co-advise Mexican Ph.D. students, including visits to UTA for research and development; design and develop an internet-based supervisory control system for manufacturing workcells; and set up a distance-learning program over the internet to train Mexican students to program workcells. Also, the research will work on industrial partner chemical flowline implementation by designing a chemical processing flowline for aircraft parts for an industrial partner, designing a DE supervisory controller for part routing and resource assignment, and simulate various strategies for part routing and resource assignment. The automated, dynamically controlled chemical flow line is a new concept in aircraft manufacturing that has the potential to gain significant market share in a new industry.
