标准的UML方法对软件质量部分如何建模是缺乏的,由此本文研究了针对软件可靠性建模和评估的UML剖面,它是基于标准UML元模型的扩展,能对系统中影响软件可靠性的因素建模;同时研究了此模型应用于传统的可靠性评估技术中的一些结论;此模型有助于贯穿软件生命期的软件可靠性工程,以提高待开发软件的可靠性指标。
Practice in today's software development involves using high level modeling formalisms to describe the overall architecture and design of a ware reliability based on UML and model aspects of systems that affect for traditional reliability assessment system. This paper studies a profile structure for modeling and assessing softproposes possible extensions of the standard UML meta- model, enabling to reliability. Meanwhile, the paper examines the systematic derivation of models from this UML design models.
