舰载指控系统软件可靠性模型分析

在对软件可靠性模型领域的众多模型进行全面分析研究的基础上，通过对从事海军指控系统软件研制单位的部分专家的实地调查，运用Ｂａｙｅｓ检验方法对专家信息进行处理，进而提出了适合舰载指挥控制系统的软件可靠性推荐模型．借鉴Ｓｃｈｎｅｉｄｅｗｉｎｄ模型在美国航天飞机飞行控制系统模型评估中的成功应用，把Ｓｃｈｎｅｉ－ｄｅｗｉｎｄ模型参数估计的思想方法运用到我们所选择的舰载指控系统软件可靠性模型中，并给出了用数据分析、判断模型的具体事例．

Analysis on Software Reliability Model of the Shipborne Command and Control System

On basis of a thorough analysis and study of existing models in the field of the software reliability, we take into account the characteristic of the shipborne command and control system. According to the supposition of the shipborne command and control system of the software which may be chosen, we have made a investigation among the experts concerned. Then we propose Bayes verification method to deal with the information from the experts, thus showing that it is correct to choose YO model as recommended model for the shipborne command & control system. Through analyzing Schneidewind model used in the US NASA Space Shuttle Primary Avionics Software System (Shuttle flight software), we use Schneidewind model parameter estimation idea in our selected model and give an example for assessing a model by considering data suitability.
