    摘要:

    区间参数高维多目标优化问题是现实生活中常见的一类优化问题,但其有效的求解方法并不是很多.对此,利用集合的概念,提出一种求解此类问题的新方法.首先,利用衡量解集收敛性、分布性、多样性的3种性能指标将原优化问题降为3目标优化问题;其次,采用集合Pareto占优关系和不确定测度来区分转化后优化问题解的优劣;再次,设计自适应变化的交叉、变异概率以提高种群的全局和局部搜索能力;最后,利用4种基准函数优化问题,对所提出方法和对比方法进行测试.测试结果显示,除了收敛性,所提出方法得到的Pareto解集的不确定性、多样性、分布性均优于对比方法.

    Abstract:

    There is few effective solving methods for the high-dimensional multi-objective optimization problem with interval parameters in real life. Therefore a new method is proposed using to concept of set. Firstly , three performance indicators including convergence, distribution and diversity of a solution set are used to transform the original optimization problem into a tri-objective one. Then, the set-based Pareto dominant relationships and a measure of uncertainty are used to distinguish the solutions of the converted optimization problem. Additionally, the adaptive crossover and mutation rates are suggested to improve the global and local search ability of the population. Finally, four benchmark function optimization problems are used to test the performance of the proposed method and comparison method. The test results show that, the uncertainty, diversity, and distributivity of a Pareto solution set obtained by the proposed method is superior to that by the contrast method, in addition to convergence.
