复杂系统仿真模型可信度评估方法对比

Comparison of credibility evaluation methods for complex system simulation model

为准确评估复杂系统仿真模型的可信度,以某飞行器非线性动力学模型为研究对象,对比多种传统可信度评估方法和基于复杂性测度的可信度评估方法的准确性。结果表明:传统可信度评估方法可以从单一方面进行模型的可信度评估并得到可信的结果,而基于复杂性测度的可信度评估方法可以综合分析信息熵、复杂度和系统结构认知图等信息,客观定量地评价模型的可信度。基于复杂性测度的可信度评估结果可为其他评估方法的准确性判断提供依据。

To accurately evaluate the credibility of complex system simulation model,the nonlinear dynamic model of an aircraft is taken as the research object,and the accuracy of the credibility evaluation methods based on complexity measurement is compared with the traditional ones.The results indicate that the traditional credibility evaluation method can evaluate the credibility of the model from a single way and result in a credible results,and the evaluation method based on complexity measurement can evaluate the model credibility objectively and quantitatively based on the analysis of information entropy,complexity and system structure cognition map.The credibility evaluation results based on complexity measurement can provide basis for accuracy judgment of other credibility evaluation methods.
