# 基于区间数的房地产投资决策方法Decision-Making Approach to Real Estate Investment Based on Interval Numbers

Abstract: Real estate investment is an industry of high investment and high risk. Scheme selection in in- vestment is important to achieve good benefits in real estate development. However, each scheme is affected by various factors. Decision attribute values represented by interval numbers are closer to reality, which may overcome the uncertainty of risk factors and the fuzziness of human thinking. In dealing with incommensura- bility indexes, weights hidden in the decision maker’s preference information are calculated by a linear pro- gramming model. With an ideal scheme and by the projection sorting principle, a projection sorting model based on interval numbers is established; the optimal scheme is selected according to the projection values. From practical instances, it is concluded that this approach has good applicability and operability.
