| 摘 要： | 着重研究了杈形自压喷灌管网系统的优化问题。根据各级管道的特点及相互关系，采用了线性规划与动态规划相结合的方法，用线性规划对各级管道进行优化；用动态规划寻求整个管网系统的优化方案。两种方法交替进行，最终求得管网系统投资最小的设计方案。这一方法便于计算机求解，具有占用内存少、运算速度快的特点。

| Abstract: | The gravity sprinkler system is the irrigation system in which the elevation of watersource is much higher than that of irrigation area,The pipes of gravity sprinkler system canbe classified into several grades,The method of optimum design for branch network which isconsidered as a whole is studied because that the investment of every grade pipe affected eachother.The linear programming and dynamic programming are adopted alternately in thelight of the properties of gravity sprinkler system and the relationships among the pipes ofsystem.The optimum design of each pipe is gained by linear programming and the optimumdesign of pipe network system is gained by dynamic programming,The design of minimuminvestment for whole system will be explored by several time calculations adopting dynamicand linear programmings alternately.The method is suited for calculating by computer. |
