Akind of Mission Computer Simulation System Credibility Research Method

研究航电优化控制系统,针对目前综合航电火控系统提高研发质量的要求,在研究中大多只选取单个静态点数据来计算可信度值,不能较好体现系统可信度全貌的现状,采用了综合航电任务机仿真系统的评估方法。根据VV&A思想给出了综合航电任务机仿真系统可信度评估流程,从功能角度划分了可信度研究层次,建立了研究模型,并综合运用相似理论和模糊数学方法,提出了新的可信度计算公式,应用最小二乘法对动态变化数据进行拟合得到可信度值变化曲线。用改进方法对任务机连续计算投放点(CCRP)水平轰炸模型进行了仿真评估。结果表明,改进方法指挥战斗效果好,为任务机仿真系统可信度研究提供了一种较好的途径。

For the current integrated avionics fire control simulation system select only a single static point data to calculate the reliability value,which can not better reflect the complete picture of the simulation system,an avionics mission computer simulation system assessment method is studied.The reliability evaluation process of avionics mission computer simulation system is given according to the VVA thought.From functional point of view,the research level of credibility is divided,the research model is established and the new credibility formulas are proposed by comprehensively using the similarity theory and fuzzy mathematics methods.Using the least square method,the curve of simulation system reliability value is fitted.Using the above method,the credibility assessment of the level bombing model of continuously computed release point（CCRP） of the mission computer simulation system is carried out,which shows that this method is simple and workable.This method provides a better way for the mission computer simulation system credibility research.
