JAWAHARLAL NEHRU TECHNOLOGICAL UNIVERSITY HYDERABAD

Overview

Course objectives:

• The objective of plant maintenance and Reliability Engineering is to achieve minimum breakdown and to keep the plant in good working condition at the lowest possible cost.
• Machines and other facilities should be kept in such a condition which permits them to be used at their optimum (profit making) capacity without any interruption or hindrance.
• Maintenance division of the factory ensures the availability of the machines, buildings and services required by other sections of the factory for the performance.
• Their functions at optimum return on investment whether this investment be in material, machinery or personnel.
• Functions and their role to enhance the plant reliability and improve the availability of the machine components.

Course Outcomes

After completion of the course the student will be able to

• Understand and describe various aspects of the plant maintenance.
• Realise the importance of maintenance and reliability.
• Analyse the various types of maintenance and their adoptability.
• Understand the concepts of reliability engineering and its role in plant performance.
• Understand reliability, availability and maintainability.
