# IME 6080 - Reliability Engineering

## Catalog Description:

The formulation of mathematical models for reliability allocation and redundancy. Topics include time dependent and time independent prediction measures for both maintained and non-maintained systems.

Prerequisites/Corequisites: Prerequisites: IME 2610 and IME 2620 or MATH 3520, or equivalent. (Recommended)

Credits: 3 hrs.

Notes: Open to Graduate Students Only.

Lecture Hours - Laboratory Hours: (3-0)

## Prerequisites by Topic:

1. Understand the concept of probability. Use of discrete and continuous random variables (IME 2620 or MATH 3620).
2. Understand the concept of statistics. Use of descriptive and inferential statistics, least squares curve fitting, and correlation (IME 2620 or MATH 3620).

## Course Objectives:

1. Apply knowledge of mathematics and engineering to reliability and maintainability problems such as formulation of mathematical models for reliability allocation and redundancy, time dependent and time independent prediction measures for both maintained and non-maintained systems.
2. Analyze and solve life distributions, empirical reliability distributions, reliability testing and planning, reliability growth analysis, and life cycle cost analysis problems.
3. Report and present individual and team’s findings for homework, case studies and min-projects.
