GAMS在灌区水资源优化分配中的应用

水资源的短缺是全球性问题,水资源优化分配是重要的农业节水措施,是目前农业节水研究的重大课题之一。当水资源优化分配中未知量较多时,传统的手工计算方法已不能满足需要,必须用计算机模型来计算。GAMS是国外应用较广的计算机语言,能通过很简单的计算程序迅速求解线性规划、非线性规划、整数规划问题。通过GAMS语言,建立了简单的灌区水资源分配模型,求解了不同水库泄水条件下的各用户最优水量分配方式。

The Application of GAMS Software in Water Resource Optimal Allocation

Water resource scarcity is a global issue. Water resource optimal allocation is one of the agricultural water saving measurement, is the important topic of the current irrigation water resource saving research. It is extremely hard or even impossible to calculate the optimal water allocation by hand when the problem includes many variables, so computer modeling is the only way to solve the problem. The GAMS is a very popular model at aboard, and suits for solving the linear, non-linear, and integer problems. Through a simple water allocation issue to introduce the GAMS model and its main characteristics, and don＇ t modifying the entire model but only changing the amount of water released from reservoir to calculate the net benefit response to the different reservoir release.
