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）与瓜达拉哈拉大学研究中心（CINVESTAV）和华雷斯市自治大学（UACJ）合作开展柔性制造系统（FMS）控制和互联网上新型离散事件（de）监督控制器的实施的合作研究提供资金。通过联合研究，结合现有成果并开发新的成果，本研究将开发FMS设计、决策和在线监督DE控制的综合方法。这项NSF/CONACyT研究有两个目标：1)制造系统DE监控控制器的结构和性能，使用UTA专利的基于矩阵的离散事件控制器作为执行制造系统监控控制器的高级设计的工具，并改进调度，路由和零件释放；研究瓶颈和最优动态再平衡以缓解瓶颈；设计并研究了多网络蜂窝制造工作单元分布式分散监控控制器的性能和复杂度。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；联合指导墨西哥博士生，包括访问UTA进行研究开发；设计和开发一个基于互联网的制造车间监控系统；并通过互联网建立了一个远程学习项目，培训墨西哥学生编写工作单元。此外，研究将通过为工业合作伙伴设计飞机零件的化学加工流水线，设计零件路线和资源分配的DE监控控制器，并模拟零件路线和资源分配的各种策略，从而实现工业合作伙伴化学流水线的实现。自动化、动态控制的化工流水线是飞机制造中的一个新概念，有可能在一个新的行业中获得巨大的市场份额。

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.
