GOALI Implementing Global Factory Schedules

项目摘要

This Grant Opportunities for Academic Liaison with Industry (GOALI) project is to develop an integrated set of scheduling and structural controllers to implement a global schedule. The investigators will not explore new methods of developing global schedules, but rather will seek to develop a systematic approach to implementing them, with implicit assumption that the global schedule accurately reflects management priorities. The scheduling controller takes the job priorities developed by the global schedule as input, and reschedules jobs in the face of disruptions to minimize deviations from the global schedule as well as improve system performance. The structural controller manages the distribution of work in the system to avoid states in which the system is vulnerable to disruptions. Thus the function of the structural controller is to make the tasks of the scheduling controller easier by maintaining a "good" distribution of jobs relative to production and material handling capacity. The researchers will formulate a novel approach for rescheduling problems, which exploit the information in a global schedule while maintaining its performance as closely as possible. Structural control policies that avoid system states, i.e., distributions of lots throughout the factory that are unduly vulnerable to disruptions will be investigated. The research will be pursued in the context of semiconductor wafer fabrication, where the investigators have extensive experience and the industrial partner is the primary supplier of such software to the semiconductor industry. Hence the team is uniquely qualified to address this inherently interdisciplinary problem and present novel, practical approaches for its solution.

与行业联络（Goali）项目的学术联络机会的机会是开发一组集成的调度和结构控制器，以实施全球时间表。调查人员将不会探索制定全球时间表的新方法，而是会寻求开发一种系统的方法来实施它们，并具有隐含的假设，即全球时间表可以准确反映管理的优先级。调度控制器将全球时间表的工作优先级作为输入，并在面对中断的情况下重新安排工作，以最大程度地减少与全球时间表的偏差并提高系统性能。结构控制器管理系统中工作的分布，以避免系统容易受到干扰的状态。因此，结构控制器的功能是通过保持相对于生产和材料处理能力的工作“良好”分配来使调度控制器的任务更加容易。研究人员将制定一种重新安排问题的新方法，该方法在全球时间表中利用信息，同时尽可能地保持其绩效。将研究避免系统状态的结构控制政策，即，将研究整个工厂中批次的分布，过度容易受到干扰。这项研究将在半导体晶圆制造的背景下进行，研究人员拥有丰富的经验，而工业合作伙伴是半导体行业此类软件的主要供应商。因此，团队具有独特的资格解决这个固有的跨学科问题，并为其解决方案提供了新颖的实用方法。
