Abstract

Once a control structure for an integrated manufacturing system is decided upon, manufacturing activities are limited by that structure. A flexible control structure is presented as an approach for accommodating a variety of manufacturing activities, without being limited to a single control structure. A flexible control structure is one that allows multiple types of control structure in the manufacturing process. The definition and the properties of a flexible control structure are discussed from the point of view of graph theory. The flexible control structure and the alternative control structures are demonstrated with a factory simulation of an automated on-line/post-process inspection system. All the control schemes are evaluated with respect to their fault tolerance characteristics, operability, and expandability. The results of this research indicate that flexible control may be cost effective when a large variety of manufacturing activities must be accommodated, but further research is needed to confirm precisely how wide a range and what types of activities would justify this approach.<>

利用工厂仿真对集成制造柔性控制结构进行评价

一旦确定了集成制造系统的控制结构，制造活动就受到该结构的限制。灵活的控制结构是一种适应各种制造活动的方法，而不局限于单一的控制结构。柔性控制结构是指在制造过程中允许多种类型的控制结构。从图论的角度讨论了柔性控制结构的定义和性质。通过对在线/过程后自动检测系统的工厂仿真，对柔性控制结构和备选控制结构进行了论证。对所有控制方案的容错特性、可操作性和可扩展性进行了评价。这项研究的结果表明，当必须适应各种各样的制造活动时，灵活的控制可能具有成本效益，但需要进一步的研究来确切地确认范围有多广以及哪种类型的活动可以证明这种方法是合理的。
