摘要 根据系统的状态信息,提出了复杂系统多信号综合信息识别和评价方法,工程应用实测表明,该评价方法可以识别和评价复杂系统的多个独立信号,具有一定的实用价值. According to the status messages of the system, a complex system of multi-signal integrative information identification and evaluation method is presented in this paper. The method discussed in the paper can identify and evaluate multi-individual signal in complex system thoroughly through the engineering applied. The method is of considerable practical value.
