is for Reliability Engineering and Reliability Theory that describes the probability of a system to complete its expected function during an interval of time. The engineering is an area focused on optimising the reliability or the probability of successful functioning, of systems such as graphs, percolations and mechanical systems such as airplanes. Originally a tool for insurance companies but nowadays more general interdisciplinary research area.

How compute overall reliability based on two related (dependent) inter-rater reliability coefficients
The Situation
In many disability programs, a physician, psychologist, or other health professional conducts an exam with the claimant. Although it's not easy, a research study could determine an inter-rater reliability estimate1 for these medical2…

Reliability of system with cold standby redundancy
If a system has one active and four redundant components, then the lower bound of the system's reliability can be calculated as $R_s=r+ \rho\sum_{n=1}^{4-1}\frac{e^{-\lambda t}(\lambda t)^n}{n!} $,where $r$ is component reliability, $\lambda$ is…

How can we use Birnbaum importance measure for complicated systems in reliability?
Birnbaum importance measure is used when we are provided the survival probabilities of all the components in a coherent system. It is the rate of increase in the system reliability with respect to the increase in component reliability. I studied…
