摘要:

废旧机械装备零部件资源的最优化重用组合,是实现废旧机械装备再制造的关键环节。分析面向废旧机械装备再设计的零部件重用组合多目标优化过程模型,建立以废旧机械装备零部件重用组合寿命均衡性、复杂性及成本为优化目标,以零部件重用策略组合为优化变量的废旧机械装备零部件重用组合的多目标优化模型,并采用第二代强度Pareto进化算法(Strength Pareto evolution algorithm 2, SPEA2)对模型进行寻优求解。以废旧C6132机床为例,验证了上述模型有效性。

Abstract:

To realize the optimal utilization of used components resources, and improve the economic benefit of its remanufacturing, a reuse optimization problem for used mechanical equipment components is studied. The redesign of components reuse and combination process model of used mechanical equipment is analyzed, then relationship between reusing strategies of used components, reuse strategy, residual service life of used equipment, and cost of reuse and combination as well as its process complexity is established, based on which a multi-objective optimization model that takes the reuse and combination strategy as the variables. In view of the problem of traditional objective weighted method, the model is solved with improved strength Pareto evolution algorithm (SPEA2). A used lathe C6132 is taken as an example to demonstrate the validity of the above multi-objective optimization model. The results show that the proposed method is effective at realizing reliability enhancement and cost reduction for a used mechanical equipment remanufacturing.
