【Abstract】 The selection of comparative case in the market of estimating real estate is introduced by quoting the approaching degree concept of fuzzy mathematics. To different uses, the corresponding characteristic factors of the kind of real estate have been decided, and qualitative description has been made to each characteristic factor, and then the weight has been marked, which is quantitated according to values to the influence degree of the factors impacting on real estate price. On the aspect of the subordinate degree of the characteristic factors, computing methods of the subordinate degree of the soft and hard quota have been proposed, and the weighted average method has been put forward in overall target. On the basis of above, a model of approaching degree and the subordinate degree has been set up, and the weight of the characteristic factors has been used in the model and the comparative cases are selected by the approaching degree.更多还原
