System Reliability Approach to Problems in Medical Field

A. Merceline Anita, Dr.A. Chandra Babu, Dr.M. Reni Sagayaraj


System Reliability approach to problems in medical field helps us to analyze the overall system reliability of medical instruments and other such systems in the medical field, from the reliability factors of the subsystems and elements. The failure of the system as a whole can be attributed to the failure of one or more components of the system not functioning in the stipulated manner.In this paper, several models of mixed series and parallel configurations with their system reliabilities are discussed, their reliabilities are evaluated through combinatorial rules of probability theory. Also their hazard rates and fault tree analysis approach(FTA) are investigated. Certain illustrations are also provided.


Failure Rate, Fault-Tree Analysis, Mixed, Parallel Configurations, Reliability, Series Configuration.
