摘　　要：针对多业务CDMA网络基站规划问题,以最小化建设成本和功率损耗为目标,建立该问题的多目标数学优化模型。针对所建模型的特点,设计基于非支配排序遗传算法(NSGA-Ⅱ)的求解方法,给出算法实现的各种关键要素。通过对一个实际算例进行求解,仿真结果表明算法能够很好的逼近Pareto最优解集,在所有获得的规划方案中基站均匀的分布在目标规划区域内,与实际规划比较吻合,从而表明所建模型和算法的有效性,能够为实际CMDA网络基站规划提供有效的理论依据。A multi-objective mathematical model optimization was built aiming at multi-service CDMA network base station planning issues in order to minimize the cost and power consumption.According to the features of the model,a solution based on the non-dominated sorting genetic algorithm（NSGA-II） was designed and then various key elements for the algorithm were given out.Through a practical solving example,the simulation experiment results indicate that the designed algorithm can approach the Pareto optimal solution set,and in all the achieved solutions,the base stations distribute uniformly in the target planning area,which is in good agreement with the actual planning.The experimental results indicate the validity of the proposed model and algorithm which can provide effective theoretical basis for CDMA network base station planning.
