By the reliability analysis of the simulative failure data , the superiority of the combined model is confirmed 通過軟件失效仿真數(shù)據(jù)的可靠性分析,驗證了組合模型的優(yōu)越性。
In the process of software reliability analysis , the combined reliability model is presented , which can improve the suitability of the reliability models to the engineering failure data 在對典型軟件可靠性模型進行研究的基礎(chǔ)上,為了改善可靠性模型對工程軟件失效數(shù)據(jù)的適用性,提出了組合可靠性模型分析的方法。
The worm , dubbed ganda - a , spreads by sending itself to e - mail addresses on an infected machine and tries to disable anti - virus and other security software and infect certain files on the hard disk , according to sophos 據(jù)說,這種病毒名為" ganda - a " ,通過在被感染的計算機上向其他地址發(fā)送郵件來傳播,并可能使防病毒和其他安全軟件失效,進一步攻擊計算機硬盤上的有些文件。
During the working process of the cluster , the linking information of clients and real servers is stored by the scheduler . when the main scheduler fails to work for some hardware or software reason , the backup scheduler does its best effort to make task handing over , based on the original linking information 在集群工作過程中,調(diào)度器保存了客戶端和真實服務(wù)器之間的連接信息,當主調(diào)度器發(fā)生硬件或軟件失效時,備份調(diào)度器盡可能在原有連接信息的基礎(chǔ)上進行任務(wù)接替。
First , this paper introduces the conception of software test , testability , and some existent model used for analyzing testability . second , we analyze the merits and demerits of each model , as followed , after we particularly investigating the process of software fault leading to software failure , we put forward our improved scheme ? stdm and specify the process that it measure software testability more logically . at last , based on stdm we design and implement a stds ( software testability detecting system ) , which can be used to measure the testability of c programs , and show the detected result in different level 本文首先介紹了軟件測試和可測試性的基本概念等用于檢測軟件可測試性的理論基礎(chǔ),并詳細分析了一些理論檢測模型及各自的優(yōu)缺點;接下來,針對這些可測試性檢測模型中所存在的問題,根據(jù)對軟件錯誤導致軟件失效過程的研究分析,本文提出了一種改進的解決方案stdm用于對軟件的可測試性進行量化檢測,文章在最后設(shè)計并實現(xiàn)了構(gòu)建在此stdm模型基礎(chǔ)之上的一個軟件可測試性檢測工具,該工具能夠?qū)源程序進行可測試性檢測并得出量化結(jié)果數(shù)據(jù),驗證了該模型的有效性。
