Extension decision-making model based on interval operation and its application to logistics center location planning

According to the characters of the logistics center location project evaluation, considering that the incomplete and uncertain intraval attribute information of the logistics center location evaluation can be reflected effectively by the traditional extension decision-making model, Extension decision-making model with grey interval number is proposed based on the grey system theory. At the course of constructing matter-element model, the interval number is leaded into the value of the matter-element characteristic variable, and a kind of grey interval matter-element is introduced to described uncertain fuzzy index information; The evaluation results with grey interval number are gotten by solving the model, and the ranking of decision-making scheme is performed by using possibility degree formula for comparing two interval numbers and formula for priority of complementary judgement matrix. Finally, an example about confirming the optimal location for the logistics network node shows the feasibility and effectiveness of this model.
