In order to improve the effectiveness evaluation of the missile weapon system with stage characteristics of flight course, based on the traditional ADC effectiveness evaluation method, carry out stage analysis for missile weapon system reliability (D), break missile flight primary stage, middle stage and last stage reliability into reliability product of different flight stage, put forwards the ADC system effectiveness evaluation method by stage. The example analysis results show that: compared with ADC system effectiveness evaluation method, the new method is correct in reliability analysis and calculation, and is more fit for weapon system work principle.%为更好地对存在阶段性飞行特点导弹系统进行效能评估,在传统ADC效能评估方法基础上,对导弹武器系统可信性(D)进行了阶段性分析,将导弹飞行的初、中、后3个阶段的可信性分解为不同飞行阶段可信性的乘积,给出了一种分阶段的ADC系统效能评估方法.算例分析结果表明:相比以往的ADC系统效能评估方法,该方法对可信性的分析和计算更为准确,更符合导弹系统的实际工作规律.
