本申请公开了一种服务器硬盘的再制造最佳寿命评估方法及系统，包括以下步骤：获取历史失效数据；基于所述历史失效数据，构建威布尔分布模型，得到物质寿命；获取价格数据，得到价格变化曲线；基于所述价格变化曲线，构建龚帕兹曲线模型，得到技术寿命；基于全生命周期成本理论和D‑S证据理论，构建经济寿命评估模型，得到经济寿命；基于所述物质寿命、所述技术寿命和所述经济寿命，构建最佳寿命评估模型进行评估。该方法能够综合考虑部件产品的残余价值和寿命进而综合评估其寿命，也适用于其他服务器部件级产品，具有较好的合理性和实用性。

This application discloses an optimal life evaluation method and system for remanufacturing server hard disks, including the following steps: Obtaining historical failure data; Based on the historical failure data, Weibull distribution model was constructed to obtain the material life. Get the price data, get the price curve; Based on the price curve, Gompertz curve model is constructed to obtain the technical life. Based on the whole life cycle cost theory and D‑S evidence theory, the economic life evaluation model is constructed to obtain the economic life. Based on the material life, the technical life and the economic life, the optimal life evaluation model is constructed for evaluation. This method can comprehensively evaluate the residual value and life of component products by considering the residual value and life of component products. It is also suitable for other server component products, and has good rationality and practicability.
