舰船装备软件可靠性验证与评价技术研究

Research on Reliability Verification and Evaluation Technology of Ship Equipment Software

针对舰船装备软件可靠性验证周期长、效率低、缺少有效手段和依据等现状,该文研究了4种软件可靠性验证统计方案,并结合验证过程中指标类型、测试环境的预期寿命、可承受的最大测试时间、可承受的最大失效数等因素,给出了不同侧重因素时软件可靠性验证统计方案的选择策略,为舰船装备软件提供一种普适性软件可靠性验证与评价方法,有效预估软件的失效率、测试周期,具有重要的工程意义。

In view of the long test cycle,low efficiency and lack of effective means and basis for the reliability verification of ship equipment software,four software reliability verification statistical schemes are proposed in this paper.Combined with indicator types,test environment life expectancy and maximum number of failures that can be tolerated,the selection strategy of software reliability verification statistical scheme is given for different factors,and it provided an important software reliability verification and evaluation method for ship equipment software,which effectively predicted software failure rate and test cycle,with important engineering significance.
