在分析了物元理论和贝叶斯网理论的基础上,提出了结合主观概率信息和客观状态信息的物元贝叶斯网模型,并给出了物元贝叶斯网在损伤定位中的推理算法.舰船损伤定位的案例分析表明,该方法可以更加全面地融合战损装备的状态信息,使损伤定位结果更为准确.“,”Firstly, matter-element Bayesian network model which can integrate information of subjective probability and objective state for system was established according to matter-element theory and Bayesian network theory. Secondly, a diagnostic inference algorithm for damage location was presented. Finally, a case of ship damage location based on matter-element Bayesian network was illustrated. The result indicates that the matter-element Bayesian network can describe the damage information more concretely and make the damage location more effective.
