The safety assessment in dynamic conditions using interval neutrosophic sets

Abstract

: In this paper, the notions of three operators, Basic Belief Assignment Operator, Dynamic Basic Belief Assignment Operator, and Dynamic Weight Vector Operator in interval neutrosophic set are defined and presented. The procedure based on Dynamic Basic Belief Assignment and Dynamic Weight Vector using Dezert-Smarandache Theory is developed to solve the dynamic decision-making problems in a neutrosophic environment where criteria values take the form of interval neutrosophic numbers collected at various periods. Practical applications for validating the proposed method and assessing system safety are given taking an example from the marine industry. The results indicate that the proposed methodology provides a feasible solution for monitoring and enhancing the safety of systems working in complex and dynamically changing environment. The model can be applied to solve multicriteria decision-making problems in diversified areas that require dynamic data.
