Review of Ethics
Last week we looked briefly at – the origins of ethics Theories of Ethics (Utilitarianism, Duty Ethics, Rights Ethics, Virtue Ethics) Engineering as a profession Codes of ethics (IIE, NSPE, Order of an Engineer) Ethics cases (e.g., space shuttles)

This week
Show how to analyze problems from an ethical viewpoint.

Analyzing Ethical Problems
1st Step – completely understand all issues involved and enumerate them. Three categories of issues – Factual – what is actually known about a
case. Conceptual – the meaning or
applicability of an idea. Moral – which moral principle is
applicable to the situation.

Line Drawing
Useful for situations in which the applicable moral principles are clear, but there seems to be a great deal of “gray area” about which ethical principle applies. Polar opposites are established.
Positive paradigm (example, pattern). Negative paradigm.
Moral problems are placed along line in accordance with where each fall on a continuum.“P” is placed where you believe problem fits relative to entries.

Example - Problem 1
Dispose of slightly hazardous waste into lake. Water source for nearby town. EPA limit 10 ppm. Average concentration of disposal – 5 ppm – Expect no health problems. Person not able to detect (taste) compound.

Problem 1 – hypothetical considerations
1. Dump 5 ppm waste in lake; harmless, but unusual taste.
2. Town’s water-treatment system can effectively remove waste.
3. Town can remove waste with company-purchased equipment.
4. Town can remove waste with taxpayer-purchased equipment.
5. Occasional (rare) illness, lasts for an hour.6. At 5 ppm people get fairly sick, lasts one
week, no long term effect.7. Special equipment can reduce ppm to “1.”

Flow Charting
Helpful when there is a sequence of events or a series of consequences that flows from each decision. Gives a visual picture and readily allows one to see results of each decision.

Please read –
Section 4.5: Conflict Problems 1st - Conflicting moral choices, but one is
obviously more significant than the other. 2nd – “Creative Middle Way,” an attempt at
a compromise that will work for everyone. 3rd – When 1 and 2 don’t work, bite the
bullet, use your “gut feelings” and make best possible choice from information available.
Section 4.6: Bribery/Acceptance of Gifts Bribery never acceptable.

Line Drawing – Causal Factor 1, 2
Negative Paradigm Positive Paradigm
Compliance with TSM and AMM was not achieved.
Compliance with TSM and AMM was achieved.
Negative Paradigm: The workers do not follow the Trouble Shooting Manual and the Aircraft Maintenance Manual resulting in troubleshooting and performing maintenance without reference
Positive Paradigm: The workers followed the Trouble Shooting Manual and Aircraft Maintenance Manual so that all troubleshooting and maintenance is performed with proper reference and guidance.

Accident Summary
April 20, 1997 – Two roller coaster cars collided on the Wildcat roller coasterThe two cars were going up a hill and an anti-rollback device failed to keep the first car on the track and it slipped back and crashed into the car behind it.The roller coaster was inspected two weeks before this accident.One person was killed and five others were injured.
![Page 24: Ethics – Part 2 IE491 October 31, 2005. Review of Ethics Last week we looked briefly at – the origins of ethics Theories of Ethics (Utilitarianism, Duty](https://reader035.vdocument.in/reader035/viewer/2022062407/56649c935503460f9494fe22/html5/thumbnails/24.jpg)
Causal Factors
1. The “chain dog” was riding up on the edge of the chain trough.
If the chain rides up the side of the car and onto the left leg of the chain near the top of the hill, the chain can disengage and the car could slip.
2. Maintenance records/maintenance of the roller coaster.
There was no documentation for scheduled or nonscheduled maintenance of The Wildcat, or for operating procedures.

Flowchart – The “chain dog” Factor
The Wildcat can operate.
Has the chain dog been changed?
No
Has someone inspected the changes?
A maintenance worker must inspect the
changes.
No
Yes
Is the “chain log” at the proper height?
Fix the height of the “chain dog” and inspect again.
The Wildcat can operate properly.
No
Yes
Yes

Line Drawing-- MaintenanceNegative Paradigm Positive Paradigm
Documentation hinders the performance of each car.
Proper documentation exists and the roller coaster is acceptable.
P
1. Every time The Wildcat breaks down, it is documented.2. Operating procedure are followed for the most part.3. Operators haven’t been trained at all.4. Changes made to the car don’t need to be written down.5. Proper part replacements should be followed.
