摘要
研究红松籽的物流集散点选址,以汪清林区红松林密集区为研究对象,在GIS平台上,结合小班数据、DEM数据等对物流集散点进行初选,再建立基于混合整数规划法的经济模型和影响因素辅助模型,优化初选地,得到汪清林区红松籽物流集散点选址21个。最后在GIS技术支持下,结合模糊数学中的贴近度分析,对所选地址评价优劣。本文的研究结果为红松籽物流集散点的选址提出一种新的构想以及实现思路,具有一定的借鉴价值,符合今后林业物流的发展方向。
This paper studies the logistics distribution centers of korean pine seeds. On the platform of GIS, the field survey data was combined with and DEM data to select primary locations. A mixed integer programming model was established with minimum costs as the economic model, and the auxiliary model of influencing factors was also established to assist the economic model. A total of 21 logistics distribution centers of korean pine seeds can be decided by the optimization of primary locations. Finally, combined with fuzzy mathematics, the proximity was calculated so that the preferential order of location selection can be obtained. The results of this study proposes a new conception and ideas on the location＇s choice of korean pine logistics distribution center, and has a certain reference value, which is in line with the future development direction of forestry logistics.
