【摘要】 以克拉玛依市给水管网改扩建工程为实例,针对改扩建优化设计为复杂的非线性规划问题,决策变量、离散变量及目标函数为多峰值函数的特点,采用基于整数编码的改进遗传算法对所建模型进行求解。将优化模型结果与传统设计的模型进行比较,说明该模型算法是可行的,减少了整个城市的管网建设投资和运行管理费用。更多还原

【Abstract】 Karamay city water supply network expansion project is used to optimize the design examples. For the nonlinear programming problem of renovation and expansion of optimal design, decision variables, discrete variables and objective function are characterized by multi-peak function that is proposed based on integer coding genetic algorithm to improve the model scheme. The results of the optimization model comparing with tradinional design model,proved that the model algorithm is feasible and credible reduce the entire city of pipeline construction investment and operation cost.更多还原
