在产率和需求均为随机的再制造逆向物流系统中,采取从用户手中买回废旧产品的方式控制回收数量.在再制造随机产率实现前决策废旧产品的回收价格;在市场随机需求实现前决策再制造产品的销售价格.企业的效用为利润的期望与方差的加权和/差,目标是最大化此效用.通过分析此目标函数下的优化模型,利用优化理论得到了给定再制造产品数量时最优销售价格的解析解,并证明了在考虑企业风险不同态度下最优回收价格的唯一性.此外,对模型进行了进一步的扩展,并利用仿真对各种参数对系统的影响进行了数值分析.
In a remanufactured reverse logistics system where both yield and demand are random, we take the method of repurchasing the used products from the user to control the amount of recovery, making the recovery price of the used products before the realization of the random yield of remanufacturing, The former decision to remanufacture the sale price of the product.The utility of the enterprise is the weighted sum and variance of the profit expectation and the variance.The goal is to maximize the utility.Through analyzing the optimization model under the objective function and using the optimization theory to get a given remanufacture The number of products, the optimal price of the analytical solution, and proves the uniqueness of the optimal recovery price under different attitudes of considering enterprise risk.In addition, the model is further extended and the impact of various parameters on the system is simulated Numerical analysis was conducted.
