Paper Abstract

Focusing on the two key aspects of the traditional sales comparison approach, case selection and case quantification of the factors, this article tries to introduce the cloud model and Case-Based Reasoning into sales comparison approach, and brings about the land appraisal approach based on the cloud model and the sales comparison approach. This approach is based on the cloud model, completely considers the fuzziness and the randomness in objects and human knowledge, describes case features with the cloud model, uses cloud uncertainty reasoning, realizes the conversion between the qualitative description and the quantification value of transaction case features ; Also based on case-based reasoning, it analyzes the correlation among different cases, searches for the required comparable one; After the modification of the different land prices of different cases, it completely considers the case features and the weight of the cases, sets up land appraisal model, and finds the price of the case. At last, it gives an example analysis whose result proves the validity and feasibility of the method.
