| 摘 要： | 为满足制造商需要快速地对市场变化做出响应的需求,需要研究产品重构领域中产品重构模型的描述和确定可重构产品的重构序列。该文对已有的一些装配和拆卸的描述方法进行分析,基于Petri网提出了一种对可重构产品进行描述的有效方法,解决了重构接口表示的问题。提出了一种考虑经济性的重构算法,使用重构成本矩阵,可以有效搜索重构路径。该文以可重构并联机器的典型驱动支链为例,验证了该方法的可行性。

| Abstract: | Manufacturing companies rapid response to market changes requires rapid reconfiguration of their manufacturing process to match market demand. The product reconfiguration model and the generation of the reconfiguration sequence are key tasks in the reconfiguration process. The assembly and disassembly of various products were analyzed to develop an effective Petri net based method to describe the structure of reconfigurable products and to represent the reconfiguration of interfaces. A sequence generating algorithm was developed which analyzes the economics of the reconfiguration cost matrix to search for the best reconfiguration path. The classic driver struts of a reconfigurable parallel machine were analyzed to show that the method is applicable and effective. |
