| 摘 要： | 传统的可靠性评估方法都是基于系统软件运行期间的失效,对于武器系统软件,由于其使用试验耗费巨资且周期很长,不可能对系统进行过多的使用试验,导致难以采集到高质量的失效数据。提出一种基于系统状态验证覆盖的Bayes软件可靠性评估方法,该方法以Bayes可靠性模型为评估准则,通过状态覆盖率来保证充分性,通过状态测试验证来保证可靠性,提倡可信性与可靠性并行增长。

| Abstract: | Based on the analysis of failures during the system running course,conventional reliability estimation approaches are unser-viceable for weapon system software,because the testing period for weapon system software is long and expensive which means impossi-ble to test much and hard to collect mass data.A Bayes reliability estimation approach based on state coverage is put award.Be guided by the Bayes reliability model,sufficiency with state coverage,reliability with state validation are assured.It advocates parallel growth for creditability and reliability of the software. |
