This paper proposes a model using Multi Criteria Decision Making (MCDM) tools viz., Grey Relational Analysis (GRA), Analytical Hierarchy Process (AHP) and Technique for Order Performance by Similarity to Ideal Solution (TOPSIS). GRA is used to shortlist the criteria from the available options, while AHP is used to assign weights to the criteria. | GRAHP TOP model for supplier selection in Supply Chain A hybrid MCDM approach Decision Science Letters 8 2019 65 80 Contents lists available at GrowingScience Decision Science Letters homepage dsl GRAHP TOP model for supplier selection in Supply Chain A hybrid MCDM approach Venkata Krishnarao Kogantia Nagaraju Menikondab S.
