利用UML映射工具实现系统可靠性建模

许多可靠性建模技术是基于可靠性框图、故障树、Markov 链等表示方法，但系统架
构师、产品经理和软件开发者往往对这些表示方法不太熟悉，他们通常使用统一建模语言UML）来对系统进行描述，因此系统设计者不得不面对设计过程与可靠性建模间的缺陷。为了弥补这一缺陷，本文提出了一个利用UML 映射工具实现可靠性建模的方法，同时以实际的例子演示了该方法的可行性。

Title：Using UML mapping tool to System reliability modeling LIN Xiaofan , DU Bin
（Department of software engineering, Chengdu university of information technology, chengdu 610225） Abstract: Most reliability modeling techniques are based on reliability block diagrams, fault rees,Markov chains and various other elements. Such formalisms may not be familiar to system architects,product managers and software developers. They normally use Unified Modeling Language (UML) to describe systems.Consequently, there is inevitably a gap between the design process and reliability modeling that system designers are facing.
This paper proposes a method which adopt UML mapping tool to fill the gap.The feasibility
of our method will demonstrate by an example.
Keywords: UML, reliability modeling, fault trees, Markov chains
