    • A method for estimating the price of real property such as a single family residence. A set of real estate properties comparable to the subject property is retrieved. The comparable properties and the subject property are characterized by a plurality of common attributes each having a respective value. Each attribute value from the comparable properties are evaluated to the same attribute value of the subject property on a fuzzy preference scale indicating desirable and tolerable deviations from an ideal match with the subject property. A measurement of similarity between each comparable property and the subject property is then determined. Next, the price of the comparable properties are adjusted to the value of the subject property and the best properties are extracted for further consideration. The extracted comparable properties are then aggregated into an estimate price of the subject property.
    • 估算单一家庭住宅等不动产价格的方法。 检索与主题属性相当的一套房地产物业。 可比较的性质和主题性质的特征在于具有各自具有相应值的多个共同属性。 可比较的属性的每个属性值被评估为模糊偏好量表上的主题属性的相同属性值,表示与主题属性的理想匹配的期望和可容忍的偏差。 然后确定每个可比性属性和受试者属性之间的相似性的度量。 接下来,将可比性质的价格调整为主题属性的值,并提取最佳性质以供进一步考虑。 然后将提取的可比性属性合并为主题属性的估计价格。
