摘要
针对航空装备体系结构复杂、要素繁多、耦合性强的特点,对其保障流程进行了研究。采用多Agent建模技术开展航空装备体系保障性仿真建模,并进行分析评估;考虑到保障过程中大量存在的主客观不确定性因素,分别采用模糊变量和随机分布2种变量形式予以描述;为符合客观变量动态时变的特点,将基于交叉熵的最大似然估计和哈密顿蒙特卡罗方法相结合,实现基于信息更新的仿真参数描述,优化航空装备体系保障仿真模型。以一个典型战训任务为例,验证了所提方法的可行性和准确性。
Aimed at the characteristics of complex structure,various elements,and strong coupling of aviation equipment system,based on the analysis of its support process,the multi-Agent modeling technology is used to carry out the supportability modeling of the aviation equipment system,and analysis and evaluation are performed.Taking into account the large amount of subjective and objective uncertainty factors in the support process,the uncertainty factors are described in the forms of random distribution and fuzzy variables.In order to conform to the characteristics of dynamic time-varying objective variables,the maximum likelihood estimation based on cross-entropy and the Hamilton Monte Carlo method are combined to realize simulation parameter description based on information update and optimize aviation equipment system support simulation model.Finally,a typical combat training task is taken as an example to verify the feasibility and accuracy of the proposed method.
