一种基于模型的可视化汽车电子软件需求表示方法

A Model-driven Visual Automotive Software Requirements Representation Approach

汽车电子软件是一类控制汽车机械和动力部件、实现各种汽车安全和舒适功能的高可靠实时嵌入式软件,其需求分析和设计方法是目前软件工程面临的重要挑战之一。本文主要研究汽车电子软件的需求表示方法,将原始需求划分为多个层次和视角,采用多种图形语言对系统的各个侧面进行表示,并揭示各个部分模型之间的关系,力图以可视化的方式形成问题空间的全景"蓝图"和局部可缩放视图。该方法的使用,有利于降低表示需求的复杂度,便于从需求模型到设计模型的平滑过渡。

Automotive software is a kind of emerging highly reliable embedded real-time software. It controls some mechanical and power components of a vehicle to achieve a some safety and comfort features. Its requirements analysis and design approach is one of the major challenges towards the present software engineering. We investigate its requirements representation approaches to form multiple graphic views and further represent the whole requirement blueprint. We divide the whole requirements into many abstract sub-requirements and further decompose each sub-requirement into several perspectives which can be modeled by some well-selected visual computes languages. This approach facilitates software requirememts the understanding and representation and the smooth transition from requirement models to design models.
