Abstract: We propose a new way to apply the WINGS method in a multi-criteria context. In the WINGS application the decision-maker can set the strength degree of each component and the influence degree of each component on others in the studied system. We consider a system whose components are alternatives. We then generate the strength degree of each alternative by applying the TOPSIS method. We denote the influence degree as preference degree. This preference degree is generated by the PROMÉTHÉE II method's preference index. We present a case study to test this proposal's consistency. We demonstrate that WINGS can be used in combination with other approaches in a usual multi-criteria context. The advantage of such an approach over the original is that in WINGS the final ranking takes into account direct and indirect relations between the alternatives.
