带有模糊参数的电子废弃物回收网络优化设计模型

Optimization Design Model with Fuzzy Parameters for Recycling Network of Waste Electronic Appliances

考虑到不确定的回收量会影响回收网络的稳健性,提出了一种带有模糊参数的逆向物流网络优化设计模型。该模型针对不确定的回收量,借助模糊线性规划的思想和解决方法,用模糊参数来描述网络中不确定的回收量,并利用容差法将模型清晰化求解。通过该模型,管理者可以由模糊的回收量得到优化的回收网络。通过算例验证了该方法的可行性。

Taking into account that the uncertain recovery quantity will affect the stability of the network, this article puts forward an optimizing model of a reverse logistic network with fuzzy parameters, aiming at the uncertain recovery quantity, based on the idea and the method of fuzzy linear programming, and using fuzzy parameters to describe the uncertain recovery quantity. The Tolerance Approach is used to clarify and solve the problem. With this model the manager can get an optimal infrastructure and the reverse network flow. Illustrative numerical examples for this linear programming problem are provided to demonstrate the feasibility of the proposed method.
