摘　　要：分析了循环经济系统中产品再利用方案的结构,对由再使用、再制造、资源化和最终处置功能构成的产品再利用方案,建立了离散现金流量和连续现金流量的净现值指标。通过净现值指标最大化来优化产品再利用方案的活动安排和现金流量分布,选择产品再利用的最佳方案。对产品再利用方案进行了示范模拟,结果显示,现金流的时间分布对方案净现值的影响和对再利用方案优化的作用,采用净现值指标评价和优化产品再利用方案比净效益指标更加科学。This paper describes the alternatives structure of used products reutilization in the recycling economy system. The net present values （NPV） of discrete and continuous cash flows of the reutilization alternative including the functions of reuse, remanufacture, recycle and disposal are analyzed. The reutilization alternative of used products is optimized and the best alternative is chosen by maximizing the net present value. The economic evaluation of the reutilization alternative of used products is stimulated as an example, which shows the effect of time distribution of cash flows on net present value and the functions of optimizing the reutilization alternative of used products, we find that the economic evaluation of the reutilization alternatives by using net present value is more scientific than by using net revenue index.
