Reliability Engineering is a discipline of engineering that holds the responsibility to test the performance of any part of a machine or an entire system. They calculate the capability of any equipment to perform for a period of time without defect. This branch is always linked with maintenance, availability, and testing. 

Reliability engineers play a vital role in deciding the quality of the equipment or machine and fixing its value in the market. They test whether the system is worth the amount by evaluating its lifetime. It is closely related to quality and safety engineering, sometimes it is also compared with system safety engineering since it also deals with the safety of the system, the operator, and the people around it along with its side effects on the environment. Any Reliability engineer should have the knowledge to handle complex systems in the industry and the complications involved in any other systems.

What is Reliability Engineering?

It is a sub discipline of several four-year-long engineering courses such as industrial engineering, mechanical engineering, electrical engineering, system engineering, etc. Several institutions offer a specialization in Reliability engineering as a two-year-long postgraduate course for candidates who have completed related courses in their bachelors and also there are certificate courses available that ranks an engineer to work as a Reliability engineer. 

While there aren’t many institutions that offer Reliability Engineering as a specific branch or department, mechanical and electrical engineering deals with this aspect of engineering as one of its professional core subjects. Reliability engineering is an analytical concept that is engaged in reducing the failures in the real time systems.

Failures are caused by many factors and some of them are induced by storage, transportation, maintenance, assembly, manufacturing and also human errors. 

These failures can be reduced by Reliability engineers by predicting it beforehand and taking preventive measures.
