KNE240 Reliability Engineering
Assignment 2
This assignment weights 10% of your final marks. It is designed to reflect your understanding of
reliability engineering principles and methods, and your skills in applying them to problem
modelling, analysis, and solving, as well as your written communication capability.
The report should be between 5 to 10 pages. It needs to be submitted before the end of study
period (18/10/2019 at 5pm) to MyLo.
Task List:
You should select one task from this list and submit your individual report for it.
1. Choose one engineering system or product that you are familiar with as your investigation
target. Examples of such an engineering system include but not limited to a car, a mobile
phone, a laptop computer, a domestic appliance, a pair of shoes, etc. Identify the reliability
causes and consequences, propose/design appropriate reliability data collection and
modelling methods, identify your reliability engineering objectives, compare the difference
with or without using the principles and methods studied in KN240 to your investigation
design, conduct reliability analysis as much as you can, and propose approaches for
reliability improvement.
2. Road safety is a critical issue in reliable driving. The reaction time is one of the most
important factors of that. Use the web test at
http://www.topendsports.com/testing/reaction-timer.htm
to test your reaction time. Based on that test, use safe driving as a case study to identify
possible risk factors, propose data collection and modelling methods, develop your response
model, and develop your safe driving standard that can be used to ensure a minimum
reliability of 99%.
3. If you have a dartboard, you can model the reliability of your combined darting function of
your brain and muscle system. Variables of condition may be the distance, time, frequency,
wind speed, etc. Design your tests, collect reasonable amount of data, build reliability
models based on the techniques we study in KNE240 and conduct analysis. Make
suggestions to improvement reliability with reasonable discussion. You can also replace the
darting with another type of activity.
