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.
