in multiobjective optimization problems where the costs(functions) are modeled by vectors, such that each dimension of the cost represents a distinct non-commensurate optimization criterion.
These methods allow us to merge objective functions into one function, which allow us to transform a multiobjective optimization problem into a mono-objective optimization problem with additional constraints.
The complexity of multiobjective optimization makes the construction of the performance function a difficult task as it can be constructed [1].
