On the Joint Reliability Importance for k-out-of-n Systems

ýIn this paperý, ýthe concept of joint reliability importance (JRI) of two or groups of components in a coherent system with independent components have been studiedý. ýThe JRI is defined as the rate at which the system reliability improves as the reliabilitiesý ýof the two or groups of components improveý.
ýGenerallyý, ýthe sign and the value of the JRI represent the type and theý ýdegree of interactions between components with respect to systems reliabilityý.
