Today’s Supply Chains (SC) are engulfed in a maelstrom of risks which arise mainly from uncertain, contradictory, and incomplete information. A decision-making process is required in order to detect threats, assess risks, and implements mitigation methods to address these issues. However, Neutrosophic Data Analytic Hierarchy Process (NDAHP) allows for a more realistic reflection of real-world problems while taking into account all factors that lead to effective risk assessment for Multi Criteria Decision-Making (MCDM). The purpose of this paper consists of an implementation of the NDAHP for MCDM aiming to identifying, ranking, prioritizing and analyzing risks without considering SC’ expert opinions. To that end, we proceed, first, for selecting and analyzing the most 23 relevant risk indicators that have a significant impact on the SC considering three criteria: severity, occurrence, and detection. After that, the NDAHP method is implemented and showcased, on the selected risk indicators, throw an illustrative example. Finally, we discuss the usability and effectiveness of the suggested method for the SCRM purposes.

The advent of Internet and recent technological developments have paved the way for IoT devices in different sectors. The demand for real-time response led to the development of fog computing which is now a popular computing technique. It provides processing, computing and storage at the network edge for latency-sensitive applications such as banking transactions, healthcare etc. This has further led to the pool of user's sensitive data across the web that needs to be secured. In order to find an efficient security solution, it is mandatory to prioritize amongst different fog-level security factors. The authors have therefore, adopted a fuzzy-based Analytical Hierarchy Approach (AHP) for ranking the security attributes in fog-driven IoT environment. The results have also been compared to the ones obtained from classical-AHP and are found to be correlated.
