By recognition of work condition, off-line identification and on-line optimization of parameters, hybrid model can be used to simulate dynamics of complex process correctly in a large scale.

通过工况的识别以及模型参数的离线辨识和在线优化，混合模型可以准确地模拟复杂过程在大范围内的动态特性。

In engineering design optimization (DO) of large-scale and complex systems, it is important to handle epistemic uncertainty which exists in design parameters and stages of DO.

在对大规模复杂系统进行设计优化的过程中，处理好各环节和各设计参数中存在的认知不确定性是十分重要的。
