摘     要
 本文在消費(fèi)者想要網(wǎng)上購(gòu)買(mǎi)筆記本過(guò)程中所需要注意的多種因素的基礎(chǔ)上，結(jié)合學(xué)生等低收入消費(fèi)群體買(mǎi)筆記本的實(shí)際情況，構(gòu)建了一套適用于評(píng)價(jià)網(wǎng)上購(gòu)買(mǎi)筆記本綜合因素的指標(biāo)體系，提出了一種基于層次分析法的網(wǎng)購(gòu)筆記本決策模型。本文在多位專家的指導(dǎo)下對(duì)所調(diào)查到的學(xué)生或者其他想要網(wǎng)購(gòu)筆記本的基本資料進(jìn)行統(tǒng)計(jì)與分析，構(gòu)造出兩兩比較的判斷矩陣。利用合積法求出矩陣的最大特征值，并結(jié)合Matlab對(duì)其最大特征值進(jìn)行檢驗(yàn)。驗(yàn)證各矩陣是否具有滿意的一致性，以確保判斷矩陣的可靠性，求出各種因素相對(duì)于上一層次的權(quán)重和底層因數(shù)對(duì)總目標(biāo)的權(quán)重。最后將專家對(duì)四種網(wǎng)購(gòu)筆記本指標(biāo)評(píng)測(cè)的數(shù)據(jù)與各因素相對(duì)與總目標(biāo)的權(quán)值相結(jié)合，對(duì)四種筆記本進(jìn)行綜合性能的實(shí)例分析，做出對(duì)不同網(wǎng)上商家筆記本選擇的優(yōu)先順序并得出了一些結(jié)論和解釋。為學(xué)生在網(wǎng)購(gòu)筆記本時(shí)對(duì)網(wǎng)上筆記本的判斷以及最終決策提供了借鑒。

Abstract
 The article construct a range of target system to eva luate 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 eva luating 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.
