Abstract: Aiming at the design problem of conceptual model for multi-scale configuration of Reconfigurable Manufacturing System (RMS),a configuration design method based on Living System Theory (LST) was proposed.The RMS configuration design process was analyzed from the scale of manufacturing system,manufacturing cell and machine tool deeply,and a multi-scale configuration model of RMS was constructed.LST was used to decompose and represent RMS multi-scale configuration conceptual model,and a universal RMS multi-scale configuration conceptual model was built based on the 20 critical subsystem of LST.During RMS configuration design process,the universal conceptual model was reused through the operations of adding,deleting or replacing,to deal with the order fluctuation and improve RMS reconfiguration efficiency.A case was studied to elaborate the implementation of the presented method and to validate the effectiveness and practicability.

Key words: reconfigurable manufacturing system, configuration design, multi-scale model, living system theory, conceptual model

摘要： 针对可重构制造系统重构过程中的构形概念设计问题,提出一种基于生命系统理论的可重构制造系统多尺度构形概念模型设计方法。从系统、单元和机床3个尺度分析可重构制造系统的构形概念设计过程,构建可重构制造系统构形多尺度模型;基于生命系统理论对可重构制造系统构形多尺度模型进行分解和表达,利用生命系统理论的20个关键子系统建立可重构制造系统多尺度构形概念设计的普遍适用模型,并采用成本对模型进行评估。面对订单波动,可以通过重用现有构形的概念模型,对其进行添加、删除、替代等操作,来实现新构形的快速设计,达到提高可重构制造系统重构效率的目的。通过一个案例研讨阐述了该方法的实施过程,并验证了算法的有效性和实用性。
