A Novel Multiobjective Optimization Method Based on Sensitivity Analysis

Abstract: For multiobjective optimization problems, different optimization variables have different influences on objectives, which implies that attention should be paid to the variables according to their sensitivity. However, previous optimization studies have not considered the variables sensitivity or conducted sensitivity analysis independent of optimization. In this paper, an integrated algorithm is proposed, which combines the optimization method SPEA (Strength Pareto Evolutionary Algorithm) with the sensitivity … Show more

“…In single-objective optimization, the fitness of solutions is reachable easily due to existing just one objective function while for multi-objective optimization, no single unique solution can be determined as the best; instead, a set of non-dominated solutions should be found in order to get a good approximation of the true Pareto fronts [3,[12][13][14], which leads to trade-off among the objectives [15,16] .…”

“…Sensitivity analysis defines the sensitivity as well as the importance of each model parameter and provides a sufficient basis for selection during model calibration. Optimizing parameters with low sensitivity increases the computation time without significantly improving the accuracy of the model [47].…”
