中文摘要：

针对目前再制造毛坯数量及质量的不确定性问题,提出了基于性能参数的主动再制造时机抉择评价模型。从产品全生命周期的角度出发,对产品性能参数在服役过程中的演化规律进行了分析。以能耗参数为核心指标,分析了产品在全生命周期（制造、服役及再制造过程）中的能耗规律,构建了产品年均能耗函数模型。在该函数模型的基础上,得到考虑能耗因素的产品最佳主动再制造时间。最后以某型号的直列六缸柴油机为例,验证了所提出方法的有效性和可行性。

英文摘要：

Since the uncertainty in quantity and quality of blanks was the main obstacle in traditional remanufacturing,timing decision-making analysis method for proactive remanufacturing was presented herein based on performance parameters.Informed by the life cycle theory,the variation of production performance in life cycle was shown,and several parameters were analyzed.Moreover,the energy consuming,which was carried as the main variable in this method,was identified in three phases：manufacturing,using and remanufacturing.With establishing the functional model of product＇s energy consuming,the optimal timing in proactive remanufacturing might be obtained.Finally,one 6-cylinder diesel engine was given as an instance to validate the proposed timing decision-making methods.
