水资源优化模型库系统构建方法探讨

Establishment of a model base system for water resources optimization

采用面向对象的方法,设计了一种支持自动化建模的模型表示方法,提出了建立水资源优化模型库系统的体系架构。该模型库系统集成了一套建模工具,能够使用户在可视化的界面中方便地修改已有的模型或构建新的模型,且系统会自动完成模型与算法的映射,从而实现了模型构建的自动化。将所开发的模型库系统应用于长江流域水资源优化管理中,取得了很好的效果。

A model representation method that supports automatic modeling is proposed by using object oriented methodolo gy, based on which, a water resources optimization model is designed. The presented model base incorporates a set of modeling tools, which gives customers an easy access to modifying the built model and constructing a new model in a visualization inter face, and moreover the system can realize mapping between algorithms and models, reaching a goal of automatic modeling. The presented model base has been applied in water resources management in Yangtze River Basin and satisfied effect is obtained.
