中文摘要：

针对可重构制造系统何时进行重构的问题,提出一种同时考虑加工功能和加工能力的可重构制造系统重构点决策方法。该方法首先从机床层次和制造单元层次识别影响可重构制造系统动态复杂度的因素,然后基于信息熵理论建立可重构制造系统动态复杂度的量化模型,并通过加工能力和加工功能的状态概率分析来求解该模型。进一步结合尖点突变理论构建可重构制造系统重构点决策模型,以积极复杂度和消极复杂度作为尖点突变的控制变量,根据尖点突变的状态突变判定条件识别可重构制造系统生产末期系统状态突变点,该突变点即为可重构制造系统重构点。以某研究所的可重构制造系统车间实际生产情况为例,阐述了所提方法的实施过程并验证了其有效性和实用性。

英文摘要：

For the problem that reconfiguration timing decision-making of Reconfigurable Manufacturing System（RMS）,a decision-making method considering machining functionality and capacity was proposed.The influencing factors of RMS dynamic complexity were identified from the machine level and cell level,and a RMS dynamic complexity quantitative model was built based on information entropy,which could be solved through the state probability of machining functionality and capacity calculation.A RMS reconfiguration timing decision model was constructed with cusp catastrophe,whose control variables were positive complexity and passive complexity.According to the cusp catastrophe mutation determination condition,RMS state mutation could be recognized,which was RMS＇reconfiguration timing.A case study from a RMS shop floor of an institute was presented to validate the effectiveness and practicability of proposed method.
