摘要
基于MCM2006A题,建立了均匀喷洒的喷灌系统优化管理模型.首先通过水力学计算,得到喷头射程、间距、数量和布局.然后将喷灌规则的确定转化为用单一小矩形条覆盖矩形区域的二维覆盖问题,针对一般情况设计了算法,得到管道移动方案.对所给喷灌区域,计算结果表明了模型的可行性.
To the problem of MCM2006A, this paper establish a model of uniform irrigating system for the optimal management. Firstly, as for the sprinklers, a hydraulic calculation is made to get the range and number of them, the span between them as well as the concrete distribution. Then, the way to determine the irrigating regulation can be converted into a planar problem of covering the whole rectangle with small rectangles. Considering the general cases, we design a way of calculation and get the scheme of how to move the pipe. To the area to irrigated, the final results verify the feasibility of the model in the paper.
