【摘要】：针对农产品产地"最先一公里"冷链网络布局问题,采用集合覆盖模型求解不同辐射半径和网点容量组合下的网络节点个数及布局方式,分析网络节点的辐射半径、容量与个数3者之间的关系,通过TOPSIS算法找出最优布局方案。结果表明:1)单一辐射半径下,随着网络节点容量的增加,网络节点个数逐渐减小,最终趋于稳定;2)网络节点个数首次出现最小值时对应的节点容量为该辐射半径下的最佳容量;3)每个网络节点辐射半径都对应1种最佳布局方式。本研究运用集合覆盖模型对某区域农产品基地进行网络布局,分析得出网络节点的辐射半径为10km、容量为15万t时的布局方案为最优,与理论分析相符,本研究提出的模型有效且可行。
[Abstract]:Aiming at the cold-chain network layout problem of "the first one kilometer" of agricultural production area, the number and layout of network nodes under different radiation radius and node capacity combination are solved by set cover model, and the radiation radius of network node is analyzed. Based on the relationship between capacity and number of 3, the optimal layout scheme is found by TOPSIS algorithm. The results show that the number of network nodes decreases with the increase of network node capacity under the single radiation radius. Finally, it tends to be stable. 2) the node capacity corresponding to the first minimum number of nodes in the network is the optimal capacity under the radiation radius. 3) each node radii of the network corresponds to an optimal layout mode. In this study, the network layout of a regional agricultural product base is carried out by using the set coverage model. The results show that the radiation radius of the network node is 10 km, and the layout scheme with capacity of 150000 tons is the optimal one, which is consistent with the theoretical analysis. The proposed model is effective and feasible.
