以模糊Petri网为工具,给出了模糊产生式规则推理Petri网模型,并将模糊Petri网与矩阵运算相结合,提出了一种模糊推理过程的形式化推理算法.在此基础上,针对产品拆卸过程中知识具有不确定性和模糊性的特点,采用模糊推理Petri网建立了产品拆卸路径决策模型,并通过实例,对所提出的拆卸路径决策算法进行了论述,结果表明此决策模型在产品拆卸过程规划中具有很强的并行处理能力,它可以根据产品在拆卸过程中零部件的信息对每一步操作做出适时的智能化决策.

Disassembly Process Planning of Products Based on Matrix Operation

Based on fuzzy Petri nets, a fuzzy reasoning Petri nets (FRPN) model is defined. And then, combining fuzzy Petri nets with matrix operation, an algorithm of formalized fuzzy reasoning process is proposed. Based on the fuzziness and uncertainness of the knowledge in the disassembly process of products, a decision making model in disassembly process is established. Furthermore, taking realistic disassembly as an example, an algorithm of decision-making in disassembly sequence is discussed. The result shows that the model of decision-making has strong parallel operation ability in the disassembly process sequence. It also can make intelligent decisions based on the product information originating from each disassembly step.
