An improved risk priority number model for FMEA based on belief measure
Chinese Control and Decision Conference, 2023 Decision making under uncertainty in risk analysis is a key issue in practical engineering. The risk priority number (RPN) model in failure mode and effects analysis (FMEA) is a widely used tool for ranking of risk items.

BDWRPN: Belief divergence weighted risk priority number for failure modes ranking and its application [PDF]
European Control Conference, 2023 Ranking failure modes in complex system is important for analysis, diagnosis and prevention of risks in practical engineering. Failure mode and effects analysis (FMEA) theory provides the risk priority number (RPN) for ranking of failure modes.

ANP/RPN: a multi criteria evaluation of the Risk Priority Number
Quality and Reliability Engineering International, 2011AbstractThis paper presents an advanced version of the failure mode effects and criticality analysis (FMECA), whose capabilities are enhanced; in that the criticality assessment takes into account possible interactions among the principal causes of failure.

Risk Priority Number vs Action Priority in Electrical Systems
International Symposium on Advanced Topics in Electrical Engineering, 2021FMEA (Failure Mode and Effect Analysis) is an important tool in evaluating a product or service either before it is made or prior to its market placing. Its purpose is to reduce any subsequent expenses due to defects. The principle of this tool says that
