Using Taguchi method for post optimality analysis in MCDM

The aim of this research is to use Taguchi's loss function to assess the loss associated with a solution provided by a particular Multi-Criteria Decision Making (MCDM) method. Although the idea proposed in this paper, derived from Taguchi's philosophy and his idea of social loss, can be invariably applied to any MCDM method, the paper utilises Goal Programming (GP) to illustrate the applicability of the proposed method.
