软件可靠性多模型综合预测研究综述

Overview on study of multi-model synthesis prediction of software reliability

针对软件可靠性工程中单个经典模型局限性的问题,Lyu等人提出了"综合"的思想,即将多个经典模型的优势结合起来。对软件可靠性多模型综合预测方法进行了梳理,分析了现有综合预测方法的优势和不足之处,在此基础上提出了软件可靠性多模型综合预测研究框架:经典模型的选择、单个经典模型权重的确定、多模型综合、综合模型的评价。并对进一步的研究方向给出了作者的看法:非线性综合以及经典模型的选择准则有待进一步深入系统的研究。

For limitations of the classical model in software reliability project,Lyu et al proposed a ＂combination＂ thinking that combines the advantages of classical models.Multi-model for software reliability prediction methods were combed and analyzed,advantages and disadvantages of every synthetic model that was proposed in existing literature were pointed out.Based on this,research framework of multi-model for software reliability prediction was proposed,that consisted of four stages： the choice of the classical model,the weights of classical models,multi-model synthesis,evaluation of integrated model.The author＇s view of further research was given： nonlinear synthesis and selection criteria of classical model is next research focus.
