产品生态化设计与再造决策

基于再制造的产品生态化设计是生产商应对内外部刺激的关键策略,在市场需求和回收量不确定情况下,产品的制造/再制造系统变得复杂化。从生产商以生产总成本最小化为决策目标,建立了数学模型并求解得到了产品生态设计率、普通产品的回收再造率和生态产品的再造率等三个决策变量的最优值。通过数例进行计算并且分别基于12种成本参数进行敏感性分析。结果表明,生产商对于决策变量具有较强的策略性选择。

Decision on the Eco-Design of Product and Remanufacture

The producer carries out a key strategy based on ecological design of product system and remanufacture in order to face the internal and external incentives.Yet the manufacture/remanufacture system about product will become more complicated under stochastic demand and returns.This paper takes the total production cost as target of decision,and establishes a mathematical model about cost.We get the optimal values of three decision variables,that is the ecological design rate of product,the remanufacture rate of general product,and the remanufacture rate of ecological product.The results from the numerical calculation and sensitivity analysis depended on twelve cost parameters show that the producer has strong strategy to choose decision variables.
