In view of Tchebycheff inequality, they adopt an approximation approach, which is to replace Roy's disaster probability by its upper bound, to obtain an analytical solution.
In MOEA/D, several methods have been proposed for decomposing MOPs into a single-objective optimization subproblem, such as weighted sum method, Tchebycheff method, and Penalty-based Boundary Intersection (PBI) method, but it was shown that the MOEA/D-PBI is only best for many-objective optimization problem in [32].
