| 中文摘要: |
| 本文目的是介绍与结合分析有关的基本概念、计算方法、两个实例以及采用SAS分析实例的方法。基本概念包括效用与分值效用、相对重要性权重、轮廓与全轮廓、正交设计与均匀设计；计算方法涉及基本思想、基本模型、分值效用的计算和实施步骤；两个实例分别是“电脑的属性和水平”以及“轮胎的属性和水平”；借助SAS，对两个实例的资料分别进行了结合分析，并对输出结果做出了解释。 |
| 英文摘要: |
| The purpose of this article was to introduce the basic concepts， calculation methods， two examples and the method of analyzing examples with SAS software related to the conjoint analysis. Basic concepts included utility and part-worth utility， relative importance weights， profiles and full profiles， orthogonal design and uniform design. The calculation methods involved the basic idea， basic model， calculation and implementation steps of part-worth utility. The two examples were “computer attributes and levels” and “tire attributes and levels”. With the help of SAS software， the data in the two examples were analyzed by using the conjoint analysis， separately， and an explanation was given for the output results. |
