外包再制造下再制造设计对制造/再制造影响

Study on the effect of design for remanufacturing on manufacturing/remanufacturing competition based on the outsourcing remanufacturing pattern

为分析外包再制造模式下,再制造设计对制造/再制造供应链竞争的影响,构建制造/再制造博弈模型.基于博弈模型,分析再制造设计费用不同承担方式对再制造设计努力程度、废旧产品回收率、收益和环境等影响.研究结果表明:原始制造商通过外包再制造不仅可以降低再制造商的市场竞争优势,还可以获得再制造带来的收益;再制造设计可以促进再制造商回收废旧产品,提高废旧产品回收率;无论是原始制造商还是再制造商承担再制造设计费用,两者收益分别在再制造设计努力程度的不同点达到最大,而不是再制造设计努力程度越大其收益越大;再制造对环境影响并不总是有利的,当单位再制造产品与新产品对环境造成的影响之比小于某一阀值,同时再制造设计给单位再制造产品带来收益与带给单位新产品收益之比大于某一阀值时,再制造才有利于降低对环境的影响.

A game model between an original equipment manufacturer(OEM)and a remanufacturer is established in order to analyze the effect of design for remanufacturing(DfR)on manufacturing/remanufacturing supply chain competition under the outsourcing remanufacturing pattern.Moreover,based on the game model,the effect of different DfR cost sharing modes on the DfR effort level,the collection rate of used products,benefit and environmental impact is analyzed.The main research results are as follows:through outsourcing remanufacturing,the OEM could not only reduce the market competitive advantage of the remanufacturer,but also increase its benefit;DfR could promote the remanufacturer to collect used products and thus improve the collection rate of used products;whether the OEM or the remanufacturer covering the DfR cost,both benefits are maximized at certain different DfR effort levels,in other words,the greater effort of DfR does not always bring the greater benefit;remanufacturing does not always reduce environmental impact,and it is more environmental friendly only when the ratio of environmental impact for unit remanufactured to new products is less than a certain threshold,and the ratio of the DfR brought benefit for unit remanufactured to new products is greater than a certain threshold.
