摘　　要：非功能特征直接影响嵌入式软件产品的质量,而传统特征模型未对嵌入式软件产品线的非功能特征细致定义。面向嵌入式产品线,提出一种非功能特征模型。首先定义特征的元模型,融合嵌入式领域扩展特征种类,生成非功能特征模型即非功能特征对象、非功能特征对象属性、非功能特征对象关系三元组,并规范其建模过程,从而解决无法清晰定义的问题。最后采用VP-UML工具对呼吸机时间量建模,验证模型的可用性,生成可扩展的基本代码,提高了需求分析效率。Non-functional features directly impact the quality of embedded software product. However, traditional feature model fails to describe non-functional feature in detail especially for embedded software product line. In view of this, in this paper we present a nonfunctional feature model for embedded product line. First we define a feature meta model; then we integrate the embedded domain extension feature class to the meta model, and generate the non-functional feature model which is a triple containing the non-functional feature objects, non-functional feature objects＇ attributes and non-functional feature objects＇ relations. We also normalises the modelling process so that the problem of difficult to clearly define is solved. Finally, we use VP-UML tool to model the amount of ventilator time to verify the availability of the model, and to generate extensible basic codes, which improves the efficiency of demand analysis.
