Optimization of urban-rural distribution network based on super-network
摘要
Abstract
To strengthen the system construction of urban-rural distribution network and to promote both the reciprocal commodity flow and the joint delivery ability, a urban-rural distribution supernetwork model comprising demand and supply networks is constructed based on the supernetwork theory. By analyzing the matching relation between demand and supply in the two networks, the organization plan of the distribution network is optimized. Firstly, the double objective optimization model is established, aiming to maximize both the time cost and the matching degree of supply and demand. Secondly, the optimization model is converted to a related variational inequality problem. Then, these two problems are proved to be equivalent and their solution is unique. Besides, the condition on which the whole network’s matching state is attained is solved through the modified projection algorithm. Finally, numerical simulation is conducted to demonstrate the effectiveness of the proposed model. The results demonstrate that the key factors influencing matching degree of supply and demand are the capacity of the logistics supply system as well as the waiting and retention of supply time.关键词
