摘要
大系统优化的关键在于模型的降维。混合模型可看作为一种降维方法,它通过把整个系统分解为联系比较松散的几个子系统,达到降维目的。从理论上对这类模型的建模原则、优化技术及其分类和特点进行了归纳和总结,说明了在多目标复杂水资源系统和排灌系统中这种混合模型的应用是十分有效的。
The key of large-scale system optimization is dimension reducing of models. The mixed-model is a method of dimension reducing by means of decomposing the total system into several sub-systems witli loose inter-connections. The principles of the model construction, the classification, the characteristics and the optimal methods of the mixed model are summarized theoreticaly in this paper. It shows that the mixed model is useful applicated in the large water resources systems and irrigation or drainage systems with complicated structures and multiple functions.
