Positioning of the Supplied Items in the Kraljic Portfolio Matrix

Kraljic portfolio matrix (KPM) categorizes materials based on two dimensions: supply risk and profit impact. In the KPM, the subjective locating of materials can cause incorrect results and adversely influence purchasing strategies. IF sets are strong to reflect the opinions of decision-makers because it is denoted by degrees of membership, non-membership, and hesitation (Yalcin et al., 2020). In this paper, fifteen supplied products of a company operating in the machinery sector are considered. Firstly, we computed the significance weights of the criteria of the KPM with the IF-AHP method. Afterward, the relative performances of the materials are derived by the IF-TOPSIS approach. It is noteworthy that eight of the fifteen products supplied are non-critical.
