The overall objective of the reliability allocation is to increase the profitability of theoperation and optimise the total life cycle cost without losses from failure issues. Themethodology, called risk-based reliability (RBR), is based on integrating a reliabilityapproach and a risk assessment strategy to obtain an optimum cost and acceptable risk.This assessment integrates reliability with the smaller losses from failures issues, and so canbe used as a tool for decision-making. The approach to maximising reliability should bereplaced with the risk-based reliability assessment approach, in which reliability planning,based on risk analysis, minimises the probability of system failure and its consequences.This paper proposes a new methodology for risk-based reliability under epistemicuncertainty, using possibility theory and probability theory. This methodology is used for acase study in order to determine the reliability and risk of production systems when theavailable data are insufficient, and to help make decisions.
