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 the quantity and quality of recycled parts complicates product design and manufacturing operations in remanufactured systems. Different from the large-scale customized production of new products, customization needs of the remanufacturing system has two-way characteristics: First, take the initiative to adapt to the needs of individual customers, diversified product customization; Second, from the amount of scrap parts, quality uncertainty led “Passive ” custom needs. Design relationship optimization configuration model to solve the problem is how to optimize the configuration planning stage of the reuse of waste components and remanufactured parts custom design relationship between the two sides to achieve the optimal coordination between the needs of customization so that the use of parts and components have been maximized Reuse, while remanufacturing components to meet the needs of customized design. Finally, the application of the model is illustrated with the remanufacturing case of saddle seat of a mining machine drill.
