STRATMAN: Development and Application of a Science Base forManufacturing System Operation and Design

这项研究将致力于为制造系统的运行和设计建立一个一致的、系统的层次化框架。该项目的目标是通过观察、实验和分析来扩展这一框架。该方法将生产系统的操作视为控制问题，并使用控制理论和工程中的概念来制定操作策略。机器故障、材料短缺和工人缺勤等潜在破坏性事件会改变系统的短期容量。它们被用作重新计算短期时间表的信号。随机调度问题被分层分解，使得重新计算速度更快，只影响生产系统的必要部分，并使系统尽可能接近生产和性能目标。本研究的意义在于开发更有效、更具反应性的生产控制与调度技术。制定灵活的时间表以反映工厂车间不断变化的需求的能力对工业极其重要。

This research will focus on developing a science base for manufacturing system operation and design is founded on a consistent, systematic hierarchical framework. The goal of the project is to extend this framework by means of observation, experimentation, and analysis. The approach treats the operations of a production system as a control problem, and uses notions from control theory and engineering to develop operation policies. Such potentially disruptive events as machine failures, material shortages, and worker absences change the short term capacity of the system. They are used as signals for the recalculation of short term schedules. The stochastic scheduling problem is hierarchically decomposed so that the recalculations are fast, affect only the necessary parts of the production system, and bring the system as close as possible to production and performance targets. The significance of this research is the development of more effective and reactive production control and scheduling technology. The ability to produce flexible schedules which can reflect the changing needs of the factory floor is extremely important to industry.
