模糊层次分析法在楼盘估价中的应用 张丹 Application of fuzzy AHP in the real estate valuation Dan zhang 2013年 5 月31日 摘 要 各国在楼盘估价过程中使用的方法是不一的，随着我国经济的高速发展，国内房地产市场也不断发育和完善，人们对楼盘价格的评估方法也在不断的探索中。由于楼盘价格的影响因素众多，为了使研究的问题明朗化，本文采用了模糊层次分析法将各影响因素量化，再综合Lagrange插值法，兼顾定性和定量两方面对楼盘进行估价。 本文首先选取了南昌市的4个楼盘作为分析对象，另外选取南昌市的2个楼盘作为评估对象，运用模糊层次分析法对影响楼盘价格的因素进行定量分析，再做指标评估，将影响楼盘价格的因素转化成线性问题来研究，阐释了影响南昌市楼盘价格的主要因素及各因素对楼盘价格的影响程度。但无法得出各楼盘的价格，于是通过对子准则层各影响因素的信息量化，再引入Lagrange插值法，通过前面4个楼盘的价格，得出待估楼盘的价格，并与楼盘的真实价格做比较，以检验本文研究楼盘价格的方法是否可行有效。 通过与实际情况结合来选取楼盘价格的影响因素，并建立的影响楼盘价格因素的模糊层次模型可对各影响因素进行定量分析，可操作性强。但是，在模糊矩阵的建立和对各影响因素的信息量化过程中存在一定的主观性，存在可改进处。 关键词：模糊层次分析法； 楼盘价格； 影响因素； Lagrange插值法  Abstract The methods used by countries in the real estate valuation process are different. With Chinas rapid economic development,the domestic real estate market is continuous development and improvement, and assessment methods of estate prices are also constantly explore by people. There are many factors to influence the real estate prices and in order to make the research problem clear, in this paper, we use the Fuzzy Analytic Hierarchy Process to quantify each factor, then comprehensive Lagrange interpolation to value the real estate prices from both qualitative and quantitative aspects. In this paper, first select four buildings in Nanchang as analytical object, in addition, select two real estate in Nanchang as the assessment object; then use the Fuzzy Analytic Hierarchy Process to quantitative analysis of the factors that affect the real estate prices and construct the evaluation index; finally, transform factors affecting the real estate prices into a linear problem and illustrates the main factors that affect the real estate prices in Nanchang and the impact of various factors on real estate prices. As the sale prices are not obtained, so through quantify the influencing factors of the sub-criteria layer, reintroduction Lagrange interpolation, and front four real estate prices, obtain the estimated s
