| 摘 要： | 以投资最小为目标函数,建立了树状灌溉管网优化数学模型,用外部惩罚函数法将问题转化为无约束优化问题,并采用改进遗传算法进行求解。根据树状管网优化的特点,遗传算法采用二进制编码和整数编码相结合的双重编码,以同时对管网布置形式和管径进行优化。在遗传算法产生初始解及交叉、变异操作时,采用基于环路的方法,减少了不可行解的产生,提高了算法的计算效率,算例说明该优化方法有效、实用。

| Abstract: | An optimization model for tree-type irrigation pipe network is established,in which the minimal investment is taken as objective function,through the outer penalty function method,the problem is transformed to nonrestraint optimization problem,and the improved genetic algorithm is used to solve the problem.Based on the optimal features of tree-type pipe network,the dual coding combining binary coding with integer coding is adopted in the genetic algorithm to optimize the pipe layout and pipe diameter simult... |
