Jeff Winter's Problem Solving Experience:

1. I started a company 10 yrs ago that was originally supposed to provide reliability and maintainability analysis using component failure history and maintenance records. Using off-the-shelf software designed to model systems using graphical logic gates we wrote a GUI overlay to create a real time dashboard that allowed you to graphically see the results of changing maintenance intervals. Because the system was based on statistical data, it could predict how many spare parts you would need, how many component failures you might expect, estimated man-hours, etc. depending on the inputs. In this way, you could optimize your maintenance intervals depending on what was most important to you (time, expense, etc.).
2. I was working on determining the optimum flow mixture for a scramjet that was cooled using liquid hydrogen and liquid nitrogen. I developed an optimization program that was able to iterate using multiple unknowns and come up with the best mixture. Using this program we were able to determine that H2 could be confined to the heat exchanger and did not need to be used directly on the engine to keep it cool. This was a significant safety enhancement that seems intuitive, but was difficult to prove because of the multiple unknown inputs.
3. While working at a nuclear plant, a problem arose with a glass window that was in the center of a door. A requirement existed that the glass be able to withstand 7 inches of water, but no analysis had been done to show that it could withstand this pressure. The engineer assigned to the task could not figure out how to prove it could take the pressure without destructive testing. I proposed just building a test rig in the shop and pouring 14 inches of water on top of the glass for 8 hours. This would provide a factor of safety of at least 2 and would not destroy the glass. A simple solution is often the hardest one to come up with.
4. I was hired to evaluate a new design for a cooling system for the Space Shuttle Orbiter. By performing a reliability analysis of the system, I was able to show that by swapping 2 valves from series to parallel, the overall reliability of the system could be improved by more than 50%.
