摘要

摘要

En 中文
电子行业致力于设计便携且高性能的产品以满足市场需求,其中高发热组件与小型化、导热能力有限的电路板之间存在矛盾。受实际需求和挑战驱动,本文提出了一种面向瓶颈的两阶段进化算法——多起点变邻域下降与遗传算法结合的MSVNDGA,用于解决受热管约束的组件布局优化(HCLO)问题,旨在最小化最大热管功率。HCLO问题被分解为热管分配(HA)和组件定位(CL)子问题以降低复杂度。首先,所提算法采用针对问题的整数编码方案将MSVND应用于HA,其中采用五种面向瓶颈的邻域结构以寻找高质量的热管分配方案。随后,GA用于确定组件坐标,从而确保在CL中生成的解满足实际工程约束。所提MSVND-GA在CEC 2022基准测试和扩展实例上进行了测试,并与当前先进方法进行了比较。大量实验结果表明,MSVND-GA在最优性、稳定性和可行解率方面具有优势。此外,该算法在2022年计算智能世界大会的HCLO竞赛中荣获一等奖。
