摘　　要：针对光电设备系统的复杂性与故障相关信息的不确定性和不完整性问题,本文提出了一种基于贝叶斯网络的信息价值的故障维修决策方法,并将该方法应用到某型号军用光电设备的激光告警单元故障维修决策中。这种方法的优点是能根据现有的信息(可能是不确定、不完整的信息)以最少的操作、最低的代价给出故障维修决策,提高了光电设备的故障维修决策能力,并大大增强了故障快速维修能力。For the complexity and uncertainty of the information trouble of Photoelectric equipment and system,decision-theoretic troubleshooting with value of information(DTT-VI) of Bayesian networks is discussed.DTT-VI is applied to a type of military equipment photoelectric laser warning unit fault decisions.The advantage of this method is based on existing information(which may be uncertain and incomplete information) to the operation at least,the lowest price given fault,thus enhancing the photoelectric equipment...
