利用UML映射工具實(shí)現(xiàn)系統(tǒng)可靠性建模

許多可靠性建模技術(shù)是基于可靠性框圖、故障樹(shù)、Markov 鏈等表示方法，但系統(tǒng)架
構(gòu)師、產(chǎn)品經(jīng)理和軟件開(kāi)發(fā)者往往對(duì)這些表示方法不太熟悉，他們通常使用統(tǒng)一建模語(yǔ)言UML）來(lái)對(duì)系統(tǒng)進(jìn)行描述，因此系統(tǒng)設(shè)計(jì)者不得不面對(duì)設(shè)計(jì)過(guò)程與可靠性建模間的缺陷。為了彌補(bǔ)這一缺陷，本文提出了一個(gè)利用UML 映射工具實(shí)現(xiàn)可靠性建模的方法，同時(shí)以實(shí)際的例子演示了該方法的可行性。

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
