摘要
测试对于准确预测导弹发射时的可靠性水平至关重要。分别从单元和系统2个层次定量地研究了测试对导弹发射可靠性预测的影响,提出了"测试重要度"这一新的度量指标,给出了其定义和代表的物理含义。算例分析表明:通过测试获取单元的健康状态,可提高导弹发射可靠性预测的准确程度;通过"测试重要度"指标分析,可找出对导弹发射可靠性预测结果影响较大的单元,从而为导弹测试方案的设计和优化提供理论依据。
Test is of vital importance to forecast the missile reliability at lunching time. Bayesian theory is used to quantitatively study the effectiveness of test to lunch reliability forecasting for missile in view of two different levels, unit and system. A new index, test importance, is proposed, and its definition and physic sense are described. Numerical examples shows that unit test can improve the accuracy about missile＇s lunching reliability forecasting; the most important units can be found by calculating the test importance, thus providing a basis for plan and optimize the testing scheme.
