Kumar says that every item is unreliable in the sense that its failure is inevitable whether sooner or later, even with the best design, construction, maintenance, and operation.
Kumar describes Reliability as ‘an integral part of design, operation, and maintenance for most engineering systems/assets. The concept of reliability discipline deals primarily with two types, namely hardware reliability and software reliability.
This is the second series of Prof. Kumar’s lecture on engineering maintenance which deals with the How’s, Who’s and Where’s of maintenance activities. It follows after the first series that dealt with the Why, What, and When aspects.
In a production or manufacturing environment, maintenance is necessary for smooth and safe daily plant operations. Maintenance engineers not only monitor the existing systems and equipment, they also recommend improved systems and help decide when systems are outdated and in need of replacement.
