Abstract: Under the assumptions that the number of distribution was determined,the issue how to determine the number of terminal nodes,the location of distribution centers and terminal nodes in city distribution logistics network under B2C mode was studied by considering the customer satisfaction level and the operational cost separately,and a two-stage layout optimization model was established.The terminal nodes'number and location were determined by the deviate center secondary clustering algorithm in first stage;the distributions'location was determined by the clustering algorithm based the minimum spanning tree and the nonlinear programming model in second stage.The numerical example was used to show the validation of the model,and the results provided important insight of layout planning on distribution centers and terminal nodes when e-commerce companies to build city distribution logistics network under B2C mode.

Key words: city distribution, distribution center, terminal node, location, clustering algorithm
