摘要/Abstract

摘要： 采用带精英策略的非支配排序遗传算法（NSGA-II）对通信电缆的绞合节距进行优化，以通信电缆的导体用量和近端串音衰减为优化目标，获得一组多样化的Pareto解集，为绞合节距的设计提供了优选空间.以25线对通信电缆的绞合节距为优化对象，结果表明，经优化获得157个Pareto解，其目标函数导体用量位于区间[55.93 kg/km，56.74 kg/km]，近端串音衰减位于区间[58.11 dB/km，94.77 dB/km]；与粒子群算法（PSO）相比，在收敛时长相似的情况下，NSGA-II的优化结果支配度100%优于PSO，其解集分布均匀程度也显著优于PSO.

Abstract: Lay length of communication cable was optimized using non-dominated sorting genetic algorithm-Ⅱ (NSGA-Ⅱ). Two object functions of communication cable dosage and near-end cross talk attenuation were designed. The solutions over diversified Pareto front were obtained. Lay length of communication cable with 25 pairs was studied as the optimization object. It is shown that 157 solutions are obtained and the dosage is in the range of[55.93 kg/km, 56.74 kg/km], the near-end cross talk attenuation is in the range of[58.11 dB/km, 94.77 dB/km]. The superiority of NSGA-Ⅱ is verified compared with particle swarm optimization. The convergence time of NSGA-Ⅱ and PSO are similar, the solutions of NSGA-Ⅱ are 100% better than PSO and distribute more evenly.

Key words: communication cable, lay length, non-dominated sorting genetic algorithm-II, non-dominated sorting
