面向资源重用的再制造定制设计关系优化配置模型及应用

Customized design relationship optimal configure model and application of the resource reuse oriented re-fabrication

回收零部件的数量和质量的不确定性使得再制造系统中产品设计及生产运作变得复杂化。区别于新产品的大规模定制化生产,再制造系统的定制化需求具有双向特征:一是主动适应客户个性化、多样化产品定制需求;二是来自于废旧零部件数量、质量不确定性导致的"被动式"定制需求。设计关系优化配置模型解决的是,如何在设计规划阶段优化配置废旧零部件重用与再制造零部件定制设计之间的关系,实现双向定制需求之间的优化协调,使得废旧零部件得到极大化的重用,同时再制造零部件能够满足定制化设计需求。最后结合某矿山机械钻具鞍形座的再制造案例对模型应用进行了说明。

The uncertainty of quantity and quality of recycled parts makes the product design and production operation in re-fabrication system more complicated. Different from mass customization of new products, the customization demand in re-fabrication system has bi-directional characteristics： one is to actively adapts the customers＇ demands of individualization and diversification, and the other is the ＂Passive＂ customization demands resulted from the uncertainty of the quantity and quality of the recycled parts. What the design relationship optimal configuration model solves is how to optimize the relationship between the reuse of configuration recycled parts and customization design of the re-fabricated parts during design planning state, enable the optimal coordination between two direction customization demands, causing the recycled parts to be re used ultimately, and allowing the re-fabricated parts to satisfy the customization design demand. At last, the explanation of model application is given by combining the re-fabrication case of the saddle seats for drilling tools used in mining machinery.
