灰色关联结果注重数据序列的整体性能评价,从算法设计上忽略数据序列细节。将灰色关联分析应用于仿真模型验证时,存在部分阶段不准确模型被大量其余阶段准确模型淹没的风险,针对这一问题,提出一种带看门狗机制的灰色关联模型验证方法,看门狗识别、吠叫和记录大差距序列数据,记录的数据结果可为后续模型修正提供细节基础,提高了模型验证的可靠性和细节可辨识度。最后,通过实例分析验证了改进模型的合理性和有效性。
灰色關聯結果註重數據序列的整體性能評價,從算法設計上忽略數據序列細節。將灰色關聯分析應用于倣真模型驗證時,存在部分階段不準確模型被大量其餘階段準確模型淹沒的風險,針對這一問題,提齣一種帶看門狗機製的灰色關聯模型驗證方法,看門狗識彆、吠叫和記錄大差距序列數據,記錄的數據結果可為後續模型脩正提供細節基礎,提高瞭模型驗證的可靠性和細節可辨識度。最後,通過實例分析驗證瞭改進模型的閤理性和有效性。

Ordinary gray relational ( OGR) analysis usually stresses comprehensive performance of time serial data. When used in valida-tion of simulation models, its comprehensive performance ignores time series’ details, which is usually part of model error. To reduce the risk in application of OGR, a new gray relational analysis with dog watch mechanism was proposed, which is in view of the details of time series. When deviation excesses threshold value, dog watches and numbers are recorded. The numbers can provide technical support for model modifying. Finally, a case study was given to show reasonability and validity of the improved model.
