摘　　要：针对消费者选购智能手机的问题,根据德尔菲法对消费者选购智能手机的影响因素进行分析,初步建立11项评价指标,利用粗糙集属性约简原理对评价指标进行约简,约简后得到的6项核心评价指标,然后利用熵权法对约简后的评价指标进行赋权,从而建立智能手机的综合评价模型,并对选取的12种智能手机进行评价,结果表明此方法是有效且合理的.The problem of consumers choosing smart phone is discussed in this paper. The influencing factors of purchasing smart phone are analyzed according to the Delphi method, and 11 evaluation indexes are initially established. Then, rough set attribute reduction principle is used to reduce the 11 evaluation indexes and the 6 core evaluation indexes are obtained. Finally, the entropy weight method is used to empower these evaluation indexes, and the comprehensive evaluation model of the smart phone is established. The selection of those 12 smart phones is evaluated. The results show that this method is effective and reasonable.
