甩挂运输作为先进的主流运输组织方式,可以产生可观的经济效益和良好的环境效果。目前我国甩挂运输发展严重滞后,把传统物流理论应用于甩挂行业,成为当前研究的热点。针对不同的甩挂组织形式,可采用不同的场站选址模型与方法。选取“多线一点、轮流拖带”的甩挂组织形式作为研究对象,在传统重心法的基础上,对甩挂场站单点选址的方法加以改进。先用重心法的改进模型确定初始参考地点,再采用经济学分析法来对各备选方案进行优化选择,从而得出合理的选址地点。结果表明,与传统的重心法相比,该方法有着更好的实际应用价值。
甩掛運輸作為先進的主流運輸組織方式,可以產生可觀的經濟效益和良好的環境效果。目前我國甩掛運輸髮展嚴重滯後,把傳統物流理論應用于甩掛行業,成為噹前研究的熱點。針對不同的甩掛組織形式,可採用不同的場站選阯模型與方法。選取“多線一點、輪流拖帶”的甩掛組織形式作為研究對象,在傳統重心法的基礎上,對甩掛場站單點選阯的方法加以改進。先用重心法的改進模型確定初始參攷地點,再採用經濟學分析法來對各備選方案進行優化選擇,從而得齣閤理的選阯地點。結果錶明,與傳統的重心法相比,該方法有著更好的實際應用價值。

As an advanced form of mainstream organizations, drop and pull transport can generate considerable economic profit and good environmental effects. At present, the development of Chinese drop and pull transport seriously lags behind. By applying the traditional logistics theory to the drop and pull industry becomes the focus of current research. For the different forms of organiza- tion, different models and methods of location selection can be adopted. Taking the organization form of multiple lines and one point, drop and pull in turn as the research object, the method of single point location was improved based on traditional gravity method. Firstly, the improved model was used to determine the initial reference site. Then economic analysis was adopted to optimize the vari- ous alternative schemes to get the reasonable location. Result shows that the method has a better practical value compared with the tra- ditional gravity method.
