再制造过程中再制造品的质量选择及其影响

在废旧品回收充足的静态环境下,假设可再制造部分的质量水平在再制造的过程中发生衰减,研究了制造商如何选择再制造品的质量以及如何有效地规划新产品和再制造品的价格。不同的不可再制造部分的质量水平会影响新产品和再制造品的市场需求量,研究表明,随着再制造品质量的不断提高,新产品需求不断降低,再制造品需求不断增加,再制造品对新产品的市场挤兑效应越来越明显,直至将新产品完全挤出市场,形成完全再制造品市场。在此过程中,制造商利润呈现出先凸后凹的增长趋势,其利润在完全再制造品市场时达到最大。

Quality Decision of Remanufactured Products and Its Impacts on Remanufacturing Process

Under the assumptions that there are adequate recycling materials and,in the remanufacturing process,the quality of return parts fall off,a study is conducted on how a manufacturer makes the quality selection of the remanufactured products,and how to determine the optimal price of the new products and remanufactured products.It is shown that the variation of quality of the non-remanufactured part has significant effect on the demands of new products and remanufactured products.With the quality continuously improved for the remanufactured products,the demands for new products keep decreasing,while it continuously increases for remanufactured products.The higher the quality of the remanufactured products is,the less demand there is for the new products.This process will continue until the remanufactured products occupy the market.In this process,the increase of the manufacturer’s profit is fast at first and then slows down.Finally,the manufacturer gains the largest profit when the market is totally occupied by the remanufactured products.
