摘     要
 本文在消费者想要网上购买笔记本过程中所需要注意的多种因素的基础上，结合学生等低收入消费群体买笔记本的实际情况，构建了一套适用于评价网上购买笔记本综合因素的指标体系，提出了一种基于层次分析法的网购笔记本决策模型。本文在多位专家的指导下对所调查到的学生或者其他想要网购笔记本的基本资料进行统计与分析，构造出两两比较的判断矩阵。利用合积法求出矩阵的最大特征值，并结合Matlab对其最大特征值进行检验。验证各矩阵是否具有满意的一致性，以确保判断矩阵的可靠性，求出各种因素相对于上一层次的权重和底层因数对总目标的权重。最后将专家对四种网购笔记本指标评测的数据与各因素相对与总目标的权值相结合，对四种笔记本进行综合性能的实例分析，做出对不同网上商家笔记本选择的优先顺序并得出了一些结论和解释。为学生在网购笔记本时对网上笔记本的判断以及最终决策提供了借鉴。

Abstract
 The article construct a range of target system to evaluate the combination property of a purchase Notebook Personal Computer on network decision model based on analytic hierarchy process. Based on a variety of factors in the analysis of customers in the course of the purchase of Notebook Personal Computer on network, we combine with the actual low income customers who want to purchase Notebook Personal Computer. In this paper, we construct a pairwise comparison matrix based on the statistics and analysis of purchasing Notebook Personal Computer on network by students. We obtained the largest eigenvalue and combined with Matlab to test the the largest eigenvalue. We verify that whether the matrix has the satisfying consistency and to ensure the reliability of the matrix, we calculate the weighting that the various factors relative to the upper ones. Finally, we combine the evaluating data of the four models’factors and the weighting that the factors relative to the general objective to analyze the combination property of the four Notebook Personal Computer models. Also we work out the priorities of choosing the model and obtain some conclusions and explanations.We provide the benchmark for students to decide the combination property of Notebook Personal Computer when purchasing on network.
