Abstract: To elicit the requirements, identify the requirements commonness and variability correctly is the key for Software Product Lines(SPL) success, which needs a particular requirement process and methods. This paper puts forward a multidimensional and hierarchical requirement process, which carves up the SPL analyse space from multi-hierarchy, observes the SPL requirements form n-dimension, and utilizes PR-Context matrix to ensure the objectivity of domain requirement analysis. It is beneficial to the practice of SPL requirement engineering.

Key words: software product line, requirement commonness and variability, multidimensional and hierarchical requirement process

摘要： 准确获取产品线需求、识别需求的共性和可变性，是软件产品线(SPL)成功的关键。该文提出一个多维分层需求过程，利用分层思想划分SPL分析空间，从不同维度观察产品需求特性，采用需求-上下文矩阵保证领域需求分析的客观性，为产品线需求工程实践提供了借鉴。
