【摘要】 废旧品回收是一个关乎企业经济效益和社会影响的问题。考虑了废旧品回收的经济成本和社会负效应最小化,建立了一个双目标规划模型。针对废旧品回收网络存在回收数量和质量的不确定性问题,结合模糊集理论,建立了回收数量和回收质量为三角模糊数的模糊混合整数线性规划(FMILP)模型。设计了粒子群优化算法对模型进行求解。最后通过算例验证了模型的可行性和算法的有效性。更多还原

【Abstract】 The problem of waste recovery is not merely economic issue but has wider impact on the environment.Even it is an inescapable responsibility of the enterprise.Considering the minimization of economic cost and negative social effect,a bi-objective program model is built.Then in view of the uncertainty of recovery quality and quantity in the waste recovery network,a fuzzy mixed integer linear programming(FMILP) model in which the recovery quality and quantity are expressed as triangular fuzzy numbers is established,combined with fuzzy set.Further more,particle swarm optimization(PSO) algorithm must be as a solution of the model.Finally,the numerical example is put forward to illustrate the implementation of the model and the algorithm.更多还原
