To improve the accuracy of the evaluation and predicting of software reliability , this paper researches on the influence of the difference of profiles on the evaluation of software reliability by starting with the difference between the operating profile and the testing profile 實(shí)際上軟件的測(cè)試剖面和運(yùn)行剖面是不同的,即測(cè)試可靠性和運(yùn)行可靠性是有區(qū)別的。為了提高軟件可靠性評(píng)估和預(yù)測(cè)的精度,本文從研究軟件運(yùn)行剖面和測(cè)試剖面的差異入手,研究剖面的差異對(duì)軟件可靠性評(píng)估的影響。
Furthermore , this paper provides several forms of failure ratio in the operating phase taking the difference between the testing profile and the operating profile into account according to the concepts of the testing reliability and the operating reliability , then analyzes theoretically the difference between the testing reliability and the operating reliability based on the changing trends that the failure of decreasing and first increasing and the decreasing of the failure ratio , and makes a research on the influence of the two types of reliability on the software releasing time 在此基礎(chǔ)上給出了考慮測(cè)試剖面與運(yùn)行剖面差別的幾種運(yùn)行階段失效率的形式,然后根據(jù)失效率遞減的和先增后減的變化趨勢(shì),從理論上分析了測(cè)試可靠性與運(yùn)行可靠性的差別,研究這兩種可靠度對(duì)軟件發(fā)布時(shí)間的影響。絕大多數(shù)軟件可靠性增長(zhǎng)模型都假設(shè)軟件故障服從同一種分布。
Firstly , this paper discusses the difference between the testing profile and the operating profile , obtains the testing ratio of coverage in the testing phase and the testing ratio of coverage in the operating phase according to practically measured data , thereby describing the difference between the testing profile and the operating profile quantitatively with the testing ratio of coverage 本文首先根據(jù)測(cè)試可靠性和運(yùn)行可靠性的概念,重點(diǎn)討論了軟件測(cè)試剖面和運(yùn)行剖面的差別,應(yīng)用實(shí)測(cè)數(shù)據(jù)驗(yàn)證得到軟件測(cè)試階段測(cè)試覆蓋率與運(yùn)行階段測(cè)試覆蓋率,從而以測(cè)試覆蓋率量化說(shuō)明了測(cè)試剖面與運(yùn)行剖面的差別。
