再制造的本质是有代价地拯救废旧产品的残留附加值,是社会资源的最优化利用途径。本着解剖麻雀的思想,以一个简单金属零件的生产和再制造为例,分解其价值形成和传递过程,建立成本模型。配合以简单实例计算,并对计算结果进行数值分析,得出零件再制造经济性判据,以管窥装备在社会大生产背景下的再制造经济性。 The essence of remanufacturing is the residual added value of saving used products at a cost, which is the optimal use of social resources. Based on the idea of ​​anatomizing sparrows, taking the production and remanufacturing of a simple metal part as an example, we decompose the value formation and transmission process and establish the cost model. With the calculation of a simple example, and numerical analysis of the calculated results obtained remanufacturing economic criteria for parts, to glimpse the equipment in the context of mass production of the remanufacturing economy.
