    摘要:

    以全面而统筹的眼光解决问题,则必须从局部分析不同的侧面,面向多视点的需求工程即为该理论的一个应用.多视点需求工程越来越受到重视,但是各视点间却缺少统一,这不仅不利于获取完整的系统需求,还导致需求变更困难等问题.为了解决以上问题,首先提出一个新的多视点建模过程框架,合理的建模框架有利于获取完整的系统需求.其次在多视点建模过程框架下建立追踪元模型,阐明系统需求在多视点元模型间的平稳过渡.最后结合需求追踪矩阵方法在追踪元模型间建立起追踪关系,进而通过计算变化追踪矩阵在需求变更时可以追踪到相关元素并进行更改,解决需求变更困难的问题.

    Abstract:

    To solve a problem with a comprehensive and integrated vision, we must analyze different aspects from the perspective of locality and consider it in a divide-and-conquer manner. The multi-viewpoint requirement engineering is getting more and more attention, but there is a lack of unity among viewpoints. This not only fails to capture the complete system requirements, but also causes difficulties in changing requirements. In order to solve these problems, this study first builds a multi-viewpoint based modeling process framework, for a reasonable modeling framework is conductive to obtain complete system requirements. Secondly, the tracking meta-model under the new multi-viewpoint modeling process framework is set up, aiming to illustrate the smooth transition of system requirements across multi-viewpoint meta-model. Finally, a tracking relationship among the tracking meta-model with the requirement tracking matrix method is established, thus relevant elements can be tracked and changed by calculating the change tracking matrix as the requirement changes. The above research can solve the problem of difficulty in requirements change.
