摘 要: 复杂系统固有客观的不确定性,探索性分析是一种处理深度不确定性的良好方法。在比较了包括探索性分析在内的多种典型的不确定性分析方法同时,指出探索性分析对分析模型的需求,针对"维数灾难"和"低层仿真结果重用"的问题,在理论上验证了基于仿真元模型是解决这两个理论问题的有效途径之一;总结了仿真元模型在探索性分析中的四种典型应用方式,给出基于仿真元模型的探索性分析过程框架;利用雷达仿真实例验证提出的方法。 Exploratory Analysis(EA) is one of good methods for studying deep uncertainty.With comparing several uncertainty analysis methods,the requirement of analysis model for EA was proposed,and the approach,i.e.simulation metamodel-based EA was validated for settling the two main theory issues in EA,that is,the dimension disaster and the low-level simulation result reuse.Four types of simulation metamodel applications in EA were summarized and a process framework of simulation metamodel-based EA was proposed,which were validated by a radar simulation example.
