摘要

本文提出了一种提高多版本软件系统可靠性的新方法。采用软件育种的软件比采用N版本编程的软件更可靠。但由于需要多次执行程序版本来检测故障模块，软件育种不适合实时应用。在该方法中，当程序版本出现故障时，在后台对故障模块进行检测，软件在前台继续执行。故障模块检测完成后，更改程序版本中模块版本的组合。为了分析新方法的有效性，进行了10次模拟，每次模拟执行程序版本10/sup 6/次。这使得故障数量减少了33%到76%，平均为56%。

A new method for increasing the reliability of multiversion software systems using software breeding

The paper proposes a new method for increasing the reliability of multiversion software systems. The software using software breeding is more reliable than one using N version programming. But software breeding is not suitable for real time application because program versions are executed several times for detecting faulty modules. In the proposed method, the detection of faulty modules is performed in the background when program versions fail and the software continues the execution in the foreground. When the detection of faulty modules is finished, the combination of module versions in program versions are changed. Ten simulations, each of which executed program versions 10/sup 6/ times, were performed to analyse the effectiveness of the new method. This resulted in the reduction of the number of failures to range from 33% to 76% with an average of 56%.
