An Application of the Flexible Best–Worst Method to Weighting Internet of Things Security Requirements

Abstract

Internet of Things (IoT) is an inter-device environment that has a significant role in many fields. Prioritization of the IoT security requirements represents an important element in the security evaluation of these systems. In this paper, we propose a Flexible Best–Worst Method (F-BWM), developed on the basis of the Best–Worst Method (BWM). The input data in the F-BWM are the best criterion and the evaluations, in pairs, between a set of criteria and the best criterion. The number of comparisons in the F-BWM is smaller than the number of comparisons in the BWM. An application of the F-BWM is made to the calculation of criteria weights for a set of IoT security requirements. A comparison of the results obtained with the help of F-BWM and BWM is realized. The criteria weights, calculated with the proposed method, can be used in multi-criteria methods for ranking a set of alternatives evaluated according to a set of criteria.
