【摘要】：为了加强城乡配送网络体系建设,促进城乡商品的双向流通和提高共同配送能力,基于超网络思想,构建了包含需求网络和供给网络的城乡配送超网络结构模型,通过分析子网之间供需匹配关系,优化配送网络的组织方案。首先建立以时间成本及物流费用匹配双目标的超网络优化模型。其次将模型转换为相应的变分不等式,并证明解的存在及唯一性,采用修正投影算法求解了整个网络达到匹配状态的条件。最后应用算例进行数值仿真,验证了模型的有效性,实验结果表明:供给能力、配送时间的等待滞留等关键参数对网络的匹配程度影响较大。此研究可为物流管理者提供决策依据。
[Abstract]:In order to strengthen the construction of urban and rural distribution network system, promote two-way circulation and improve the urban and rural commodity distribution capacity, super network based on the constructed network and demand supply networks and rural distribution network super structure model, through the analysis of sub network matching relationship between supply and demand, organization scheme of distribution network optimization. Firstly establish the optimization model with time cost the cost of logistics, and target of the super network. Secondly, the model is converted into the corresponding variational inequality, and prove the existence and uniqueness of the solution, the modified projection algorithm for the entire network to match the conditions. Finally the application example of numerical simulation, to verify the validity of the model, the experimental results show that: supply capacity, delivery time for retention of key parameters such as the matching degree of the network influence. This study can provide basis for the decision-making of logistics management.
