Introduction to Reliability: Concepts and definition of Reliability – Reliability mathematics – failure distributions.
Hazard models – hazard rate function – failure density function – conditional reliability – exponential, Rayleigh, Weibull, Normal and Lognormal distributions – two-parameter exponential and three-parameter Weibull distributions – MTTF, MTBF – design life.
Reliability of simple Systems – Series and parallel configurations – Reliability improvement – redundancy – combined series and parallel systems – High level and low level redundancy – k-out of n system – standby redundancy.
Maintainability – Factors affecting maintainability of systems – Design for maintainability – MTTR – Maintenance – spare provisioning.
