Course Objectives
At pletion of this course, each student
• Have a good understanding of reliability and how to
manage it
• should have an understanding of the basic models and
methods of reliability engineering and their application to
complex systems,
• should be able to collect and analyze failure and repair
data, derive an appropriate model, and apply the model to
analyze desired reliability, maintainability or availability
goals

Prerequisites
A reasonable knowledge of tech maths and
calculus.
I really did enjoy that
stat stuff with all of
those great numbers!

2. One test for 10%
3. prehensive final examination for 35%
You mean I may have
to work in this class??

Some Definitions
Reliability is defined to be the probability that ponent or system
will perform a required function for a given period of time when used
under stated operating conditions - R(t).
Maintainability is defined to be the probability that a ponent
or system will be restored or repaired to a specified condition within a
period of time when maintenance is performed in accordance with
prescribed procedures - M(t).
Availability is defined as the probability that ponent or system is
performing its required function at a given point in time when used under
stated operating conditions - A(t).

Some Definitions
Reliability
The definition of reliability has 4 key elements:
• The quantification of reliability in terms of probability
of failure
• A sta
