数学模型在购房决策中的应用

Application of Mathematical Models in the Purchase of House-shopping

建立了多目标决策的数学模型,利用集对分析法对消费者购房问题进行了讨论.通过市场调查确立出影响消费者购房的五个因素,利用熵值法求出各个因素的指标权重并建立评价矩阵,确立理想方案,综合比较得到最优购房方案.通过实例分析说明了此方法的可行性,对于居民在购房决策时有一定的参考价值.

The article established the mathematical model of multi-objective decision, and set pair analy- sis method is used to discuss the consumers＇ purchase problem.Through the market survey the five factors that affect consumer buying are identified;entropy method is used to calculate the index weight of each factors and establish evaluation matrix;the ideal solution is established;the optimal purchasing scheme is bbtaihed through a comprehensive comparison.The example analysis shows the feasibility of this method.
