Abstract

•The interrelationships between failure modes are considered.•q-ROFS is applied to capture more risk evaluation information.•A q-rung orthopair fuzzy cognitive map is introduced for reasoning the relationships.•The maximum deviation measure is applied to determine the weights of risk factors.•The TOPSIS under the projection measure is improved for prioritization.
