摘　　要：对Geol-Okumoto软件可靠性预计模型进行了分析和研究,找出了该模型存在的主要缺陷和不足,针对G-O模型不能对产品的操作阶段进行评测不足之处,对该模型做出了错误排除率正比于潜在的错误点发现率新的假设条件,并给出了一个基于测试覆盖的CGO模型。通过失效数据对GO模型和CGO模型在性能上作了对比分析,结果表明CGO模型具有更好的预测效果,而且还可以在操作阶段进行可靠性评测。Researches on software reliable prediction model also referred to, seeing that the GO model cannot carry on the evaluation deficiency at the product operation stage, this article makes new supposition condition to the model about the mistake removing rate direct ratio to the latent wrong spot discovery. Besides, it gives us a CGO model based on the test cover. By contrasting the performance of the GO model and the CGO model with the use of failure datum, we know that the CGO model has better forecasting effect. Moreover it can also perform the reliable evaluation at the operation stage.
