        ENRE 446(489D) Applied Reliability Engineering II (3 Semester Hours)

        Course Description:

        This course is the second of a two-course sequence that will provide a semi-intensive survey of the complete field of reliability engineering. The courses are designed to give a thorough philosophical base for reliability engineering along with frequent examples of application. Students completing these course will have a good understanding of the actions and goals of a state-of-the-art reliability program and will become familiar with current techniques and their use in producing robust products. Examples will cover a range of different applications with the objective of helping the student to appreciate the challenges in the
        varied components of complex products and systems.
