Today's production manager must deliver performance improvements at an increasing pace in order to meet the objectives of "better, faster, cheaper and cleaner." Globalization, increasingly diverse and sophisticated customer markets, the rapid pace of technological change, scarcity of natural resources, and stringent environmental controls have all contributed to a turbulent business environment. Today, if a manufacturer is satisfied with the status quo, it is flirting with extinction. Technology, in the form of equipment and information systems, has always been a route to higher efficiency and improvement. However, an equally important - and in some cases more important - avenue for competitiveness is the way we organize and manage production systems. There is an emerging consensus that existing layout configurations do not meet the needs of multi-product enterprises and there is a need for new generation of factory layout that are more flexible, modular, and easy to reconfigure. The proposed research will provide in-depth undersigning to rapid modeling and simulation of non-conventional manufacturing systems to answer questions related to: changes in product mix and volume; relocation, addition and deletion of machine tools; reconfiguration of material handling system; operator assignment, shift-scheduling and capacity adjustment; and product lot sizing and scheduling. Main contribution of the proposed research will be made in developing: (1) Models, algorithms and computerized tools to design and optimize non-conventional manufacturing systems such as cellular, fractal and reconfigurable manufacturing systems; (2) Manufacturing systems performance metrics tailored to the design criteria of these non-conventional manufacturing systems; (3) Methodologies for automatic synthesis and generation of supervisory control algorithm for reconfigurable manufacturing systems; (4) Simulation model generators to evaluate several reconfiguration decisions in reconfigurable manufacturing systems on a recurrent bases.

今天的生产经理必须以越来越多的步伐进行绩效提高，以实现“更好，更快，更便宜和清洁的目标”的目标。全球化，越来越多样化，越来越复杂的客户市场，技术变革的迅速速度，自然资源的稀缺和严格的环境控制都为动荡的商业环境做出了贡献。如今，如果制造商对现状满意，则它正在灭绝。以设备和信息系统的形式，技术一直是提高效率和提高的途径。但是，同样重要的 - 在某些情况下更重要的是，竞争力的途径是我们组织和管理生产系统的方式。有一个新兴共识，即现有的布局配置不满足多产品企业的需求，并且需要新一代的工厂布局，它们更灵活，模块化且易于重新配置。拟议的研究将为非规定制造系统的快速建模和模拟提供深入的签名，以回答与以下问题相关的问题：产品组合和数量的变化；机床的搬迁，加法和删除；物料处理系统的重新配置；操作员任务，班次安排和容量调整；以及产品尺寸和日程安排。拟议研究的主要贡献将在开发中做出：（1）模型，算法和计算机化工具，以设计和优化诸如蜂窝，分形和可重新配置的制造系统等非规定制造系统； （2）制造系统的性能指标，适合这些规定制造系统的设计标准； （3）用于自动合成和生成可重新配置制造系统的监督控制算法的方法； （4）仿真模型发生器评估在经常性基础上可重构制造系统中的一些重新配置决策。
