基于HLA的鱼雷武器性能仿真系统及其VV&A研究

讨论了高层体系结构(HLA)技术应用于鱼雷武器性能仿真的需求和关键技术以及该仿真系统的VV&A:(1)建立精确的武器系统仿真模型;(2)解决实时性问题;(3)建立有效的VV&A技术保障。在基于HLA的鱼雷武器性能仿真系统的FEDEP开发过程中利用Labworks工具集辅助进行FOM/SOM校核、互操作性校核以及联邦测试等VV&A过程,采用主观判断分析、软件测试和频谱分析等方法对鱼雷控制系统模型、弹道模型和自导系统模型进行了校核与验证,提高了HLA仿真试验结果的可信度。     

基于群体AHP的仿真可信度评估方法研究

群体层次分析法（Group AHP）是由多个具有相关领域不同知识和经验的专家参与的群决策方法,提出了基于该方法的系统仿真可信度评估方法。首先验证各专家给出的判断矩阵的一致性,并确定判断矩阵每行的可信度,再计算各判断矩阵的可信度,给出判断矩阵中各要素的相对权重,最后得到仿真可信度的定量指标。应用结果表明,该方法能更好地集中了各专家的智慧,克服人为主观判断、偏好给决策带来的影响,因而更符合客观规律,为仿真可信度的定量评估提供了有效的技术途径。

Abstract：

Group AHP （Group Analytic Hierarchy Process） is a method of Group Decision executed by many experts who have different knowledge and experience. The method of simulation credibility evaluation based on Group AHP was proposed. In this method,the consistency of every judgment matrix built by experts was verified firstly. And every row＇s credibility of judgment matrix was given. Then reliability of every judgment matrix was calculated and the weight was constructed. Finally,quantitative credibility of simulation system was calculated. Group AHP collects intelligences of experts and reduces subjective effects and biases. The application result shows that the method is reasonable and feasible.
