About Reliability Engineering

Engineering reliability is the testing, maintenance, and operation of components, products, plants, or processes so that they perform their intended functions without failure, under specified conditions, for the appropriate amount of time. The product lifecycle management process emphasizes dependability, which refers to a component's ability to operate for an extended period under stated conditions. Thus, reliability is a composite concept consisting both of time and stress. As a product, it must remain robust over several years of its life and also perform its intended function without failing due to attacks from temperature, vibration, shock, voltage, and other environmental stressors. This quality management principle ensures that a component, product, plant, or process performs its intended function without failing for the specified period and in a specified environment. Functional reliability is the process of applying these principles to long-term product availability. Reliability engineering is the method of applying these principles.

What is Reliability Engineering?

Reliability engineering involves an iterative process of reliability assessment and improvement, and the relationship between these two aspects is essential. Working on the reliability of a system necessarily involves assessing its reliability. Occasionally, the assessment results in the system being sufficiently reliable. The assessment work may also reveal ways to improve reliability when reliability is determined to be insufficient. Reliability assessment is generally accepted as having a value in determining the potential reliability of a system and identifying possible ways to better it. However, the reliability engineer cannot wait until all the reliability problems of his fellow engineers have been resolved. As such, it is his responsibility to determine which areas require improvement for the project to succeed. For the rest, he must accept, as given, the levels of reliability currently achieved. Other engineers, however, do not have to get such a standard. They are the ones who are in a position to reduce the number of failures. These techniques should be used by them as well. However, it would be disastrous if they assumed that the current level of reliability would not be altered.

Eligibility in Engineering in Reliability Engineering 

An RE needs to have problem-solving abilities, a team-oriented attitude, stability under pressure, written and verbal communication skills, and excellent interpersonal skills. Having the talent to work well with others is essential to solving problems effectively. REs should not be expected to know all the answers. Still, they should be able to tap into the expertise within the organization. Using tools such as criticality analysis, failure mode and effects analysis (FMEA), root cause analysis (RCA), and critical spares analysis, this RE manages risks to achieve strategic objectives. REs manage the Predictive Maintenance Strategy (PDMS) and online condition monitoring programs for their area of responsibility. Additionally, the RE helps with the design and installation of new assets, modifying existing assets, and providing technical support to facilities management, technicians, and production personnel to mitigate operational issues.
