Reliability engineering is a field of engineering focused on ensuring that products and systems perform consistently and dependably over time. It involves analyzing potential failures, understanding their causes, and implementing strategies to minimize risks. This discipline is crucial in industries like aerospace, automotive, and electronics, where safety and performance are paramount. The goal of reliability engineering is to enhance the lifespan and functionality of products while reducing maintenance costs. Techniques such as failure mode and effects analysis (FMEA) and reliability testing are commonly used to identify weaknesses and improve overall system reliability.
