Introducing Reliability and Maintainability in Engineering and TechnologyUndergraduate engineering technology education is traditionally concerned with teaching howmanufactured products work. The ways in which to avoid product and systems failure, that is thetheory of reliability and maintainability, are generally not taught because it is necessary tounderstand how a product works before considering ways in which it might fail.Today, there is a greater need of reliability in the performance of products and equipment as thedemands of the global economy require manufacturers to produce highly reliable and easilymaintainable products. One common factor in the design and development of products has beenthe need of improving their inherent reliability that is, their ability to perform a specified taskrepeatedly without breakdown or failure.The need for reliability and maintainability has been ever increasing because of competition,evolution of new materials, methods, safety and product liability considerations, and increase incomplexity of systems. It is becomes necessary then that our engineering technology graduateshave the basic requisite knowledge in this multi-disciplinary field. With this in view, a course onreliability and maintainability has been recently introduced in our graduate-level program.This course provides an intensive and comprehensive introduction to all essential aspects ofmaintenance and reliability in design, manufacturing, and service functions of mechanical andelectronic components in products and systems. Students learn theory of reliability, includingmethods to evaluate component reliability such as fault tree analysis and network reductionmethod, maintenance and replacement models, corrective and preventive maintenance,maintainability and reliability during product and system design.The class assignments and project work allow students to integrate and apply the knowledge totasks that include designing for reliability and maintainability, developing appropriate qualityprocedures, and incorporating failure and repair data analysis for their asset managementprograms.This paper describes the course, its basic layout, assignments, past project work, and typicalexamples of assignments done by students. The paper also describes the student feedbackobtained so far that helps to streamline the course structure and content.
