Research On The Sitting Method Of Logistics Nodes Of Expressway Service Area

Expressway service area is an important infrastructure of expressway, modernlogistics is the foundation and "artery" of national economy, which is known as "thethird profit headspring". With the development of our country’s social economic,expressway network and the scale of expressway service area, logistics functionexpansion is an important development direction of the expressway service area, theexpressway service area logistics node location is an important link of that.This thesis researches the expressway service area logistics node location methodunder the condition of expressway network gasification. This thesis analyzes theexpressway service object and advantage and environmental conditions of servicearea development logistics service, determines main function of the service arealogistics node; on the basis, combined with the specific characteristics of service area,through the analysis of influence factors of logistics node location set up locationdecision model based on support vector machine, and introduced Particle swarmoptimization algorithm to optimize the parameters of the model; finally analysis theexample used by the model and algorithm, and verify the effectiveness of the methodthrough analysis of the results.At present, three are not many related research achievement of expresswayservice area development logistics function for the purpose of improve the overallbenefits of expressway service area logistics and promote the development of modernlogistics at home and abroad, this thesis explores our country’s problem about theexpressway service area logistics node location decision which is helpful to improvetheoretical system and methods of logistics services development of our country,meanwhile research of this paper has certain practical significance of promoting ourcountry expressway service area logistics node location practice under the conditionof expressway network gasification.
