考虑产品可拆卸性的再制造模式决策

Decision-making of Remanufacturing Considering Product Disassemblability

为研究产品可拆卸性对再制造决策的影响,本文针对OEM(Original Equipment Manufacturer,原始设备制造商)再制造(Model M),IO(Independent Operation,第三方独立再制造商)再制造(Model R),OEM和IO共同再制造(Model C)这三种再制造模式,在考虑不同产品可拆卸性策略时,运用Stackelberg博弈研究了OEM为主导作用时OEM利润的变化规律。研究表明OEM再制造决策取决于不同产品可拆卸性策略的固定投资成本差额和市场规模。当不同产品可拆卸性策略作用下的OEM初始固定投资成本差额较小,采取可拆卸性高的产品再制造策略可以提升OEM的利润;反之可拆卸性低的产品再制造策略更优。当市场规模较小时,OEM在Model R中获利最高;反之,OEM在Model M中获利更高。在Model C中产品之间的竞争程度不受初始固定投资成本差额和市场规模的影响,OEM获利最低。通过算例分析在初始固定投资成本差额和市场规模作用下OEM的利润波动规律,为核心企业再制造策略的选取提供依据。

To research the effect of product disassemblability on remanufacturing decision-making,three remanufacturing models are constructed：OEM（Original Equipment Manufacturer）Remanufacturing（Model M）,IO（Independent Operation）Remanufacturing（Model R）,OEM and IO Remanufacturing simultaneously（Model C）.Under different product disassemblability strategies in three models with OEM-led Stackelberg game,the profit of OEM is studied and compared respectively.Results show that high product disassemblability strategy improves OEM profit when the difference between the initial fixed investments in two product disassemblability strategies is small;on the contrary,low product disassemblability strategy improves OEM profit.The OEM is more profitable in Model R when the size of market is small;otherwise,the OEM gains more profits in Model M.However,the product disassemblability strategies and the size of market do not affect the fierce competition among different products in Model C,resulting in the lower profit of OEM compared to other two models.The effects of product disassemblability strategies and the size of market on the profit of OEM in three models are analyzed through the numerical simulation.It is beneficial for the core enterprises to take appropriate strategy for remanufacturing.
