【正文】 business model, so logistics distribution center is different from traditional model to some extent. The main differences display as Table 1. Table 1 The main differences between logistics distribution center under the emerce environment and traditional mode The feature of logistics distribution center in the environment of EBusiness The feature of traditional logistics distribution center region is broad center only distribute the products to the fix place quantity ,frequency, direction of distribution is unstable quantity , frequency, direction of distribution is stable quantity one time ,more number of times number of times, more quantity one time From Table1, pared to the traditional distribution center, the development proposes the more strict demand: only faster distribution rate and better distribution quality can make us keep pace with the trends of Ebusiness and improve the satisfaction of users and the petitiveness capacity of the enterprise. It is very important to choose the right distribution center. 2 The primary factors which will affect the locationselect under emerce environment. To choose distribution center under Emerce environment properly, we should consider the market, money, natural environment, economic environment, invest environment and other factors which are related to affect distribution. According to the conclusion based on a lot of research in this area, the factors which we must mainly consider when we select logistics distribution center are as follow: Table 2 The primary factors which should affect the locationselect in the environment of ebusiness The primary factors Natural environment factors Terrain, geology, hydrology, weather Economic factors Transport cost ,land cost, operate cost, product feature Invest environment Transport condition, public facilities, operate environment, surrounding Other factors Territory use, environment protection, Qos policy 3. THE PROBLEMS EXIST IN THE COMMON LOCATION SELECT AND THE METHODS OFLOGISTICS DISTRIBUTION Unary node locationselection focus method Unary node locationselection means only set one logistics facilities arrangement. The focus method regards the requirement point and the resources point as a logistics system which is located in the range of a plane, the requirement quantity and the resource quantity as the weight of the objects, object system focus as the best set point of logistics work node. It solves object system focus to fix the location of the logistics work node. Mathematical model is: 3 1111nnj j j j jjjnnj j j j jjjx c w x c wy c w y c w?????????? The mixed integer planning method of the work node to be elected Aiming at social economic benefit, Logistics work node arrangement considers the situations of materials demands, transport conditions, natural environment with a systemic method prehensively, design and research on the amount, location, size, supply area of logistics work node, and establish a high efficiency logistics work system.
