RESEARCH ON THE MODEL OF PARTNERS' SELECTION FOR PORT LOGISTICS ENTERPRISES BASED ON THREE PHASES

Based on the features of port logistics, this paper utilizes three phase model to select the cooperative partners of port logistics. The primary selection phase sets the unalterable indexes to eliminate the unqualified candidates. The filter selection phase constructs the index system to evaluate the cooperative partners, and then calculates the interrelatedness degree and the priority degree by using the dependence function of the extension theory to select some better candidates into the optimal process. The optimal phase establishes an integer-programming model to solve the multi-objective optimization problem, with the consideration of the concept of joint-cost that includes transaction costs. And it solves the integer-programming model with the Dijkstra method of minimum path arithmetic so as to enhance the effectiveness of the result. At last, it gives an example to utilize the three-phase partner selection model of the port logistics enterprises, which proves to be an effective method.
