软件系统中的各种错误或错误是导致软件不可靠的一个因素，但尚未得到适当的重视。本文的目的是演示故障多样性对检测软件错误的时间的影响。提出了一种新的基于多项式分布的离散软件可靠性模型。结果表明，对于这类模型，故障概率越多样化，检测或消除任何n个故障所需的时间(随机)越长，而在给定时间内(或在给定系统输入数目期间)检测或消除的故障个数(随机)将越小。对于耶林斯基-莫兰达模型，断层多样性的影响也得到了证明。
Diversity of bugs or faults in a software system is a factor contributing to software unreliability which has not yet been appropriately emphasized. This paper is written with the intention of demonstrating the impact of fault diversity on the time to detection of software bugs. A new discrete software reliability model based on the multinomial distribution is introduced. It is shown that for models of this type, the more diverse the fault probabilities are, the longer (stochastically) it takes to detect or eliminate any n faults, while the smaller (stochastically) will be the number of faults detected or eliminated during a given amount of time (or during a given number of inputs to the system). The impact of fault diversity is also demonstrated for the Jelinski–Moranda model.
