摘　　要：将灰色理论应用于软件可靠性建模研究,通过对历史失效数据进行建模,对软件的下一步失效时刻进行预测。为验证该模型的预计精度,将其应用于多组广泛被认可的数据,通过计算度量元短期相对误差(SRE)与经典的可靠性模型进行比较,结果表明,基于GM的模型对将来失效时间间隔的预测更加准确。Grey theory is applied to the study of software reliability modeling.Through modeling with history failure data,the next-step failure time was predicted.To verify the accuracy of the Grey Model(GM),the authors applied it to a group of generally accepted data,and compared the results with that of traditional software reliability growth models by computing the SRE measure.The experimental results show that in most cases,the GM ranks first as far as the short-term predictability is concerned.

关 键 词：可靠性增长模型 灰色模型 失效间隔预测
