An Uncertainty Multi-objective Optimization Based on Interval Analysis and Its Application
摘要
Abstract
An interval multi- objective optimization method was suggested based on non- linear interval analysis methods. The upper and lower bounds of every objective and constraint functions for each vector were calculated, by using the center value of the interval objective function, the non-dominated solution of the multi-objective optimization problems was calculated,with the interval possibility degrees,the nonlinear interval multi-objective problems were changed into the deterministic multi-objective problems. TheμMOGA was used to calculate the converted deterministic multi-objective problems. Finally, the method was applied to one numerical example and two engineering problems about ten truss structure and commercial automobile frame optimization. The results of these examples demonstrate the efficiency and engineering practicability of the presented method.关键词
