A grey mathematics approach for evolutionary multi-objective metaheuristic of project portfolio selection

Abstract

The aim of this chapter is to present the results of the comparison between the solutions obtained with the grey mathematics and the solutions obtained without the grey mathematics. The grey mathematics is used to represent the uncertainty associate with real-life decision-making. We define a multi-objective algorithm to perform the comparison between algorithms. The results obtained show that the approach using grey mathematics outperforms the results without grey mathematics.
