Are you that guy who says an earthquake is gonna swallow up RWY 27 KMEM due to cracks in the concrete?

We want to deliver as close to 100% of our packages on time every day. FedEx has several planes every night that fly empty on strange routes just to be able to drop in on a city if the scheduled flight from that city breaks or is delayed. Where would that fit into your algorithm? As JetJok said, I'm pretty sure the FedEx guys run the numbers every night.

Nah, it doesn't work that way here at brown. Our cost saving algorithm, or brown-'o-rithm is very straight forward.
The management's well-being is directly but inversely proportional to line pilots' well-being. I.e., the more they screw with us - the happier they get.

Truth be told ... damage estimates for the Memphis area from a potential New Madrid Fault earthquake are catastrophic. It's responsible for some of the largest magnitude quakes ever recorded in North America!

Times have changed at Brown, it is all about the cheapest. Service failures can be blamed on weather, etc.

Its gotten so bad, rumor has it that the name is actually UP, the 'S' has been dropped to save a dollar.

Perhaps your algorithm is better than theirs, which would be hard to believe. But if that were the case, you shouldn't be talking with dumb-assed pilots here. You should be talking with guys like Ronald T. Piervincenzi and Fred Smith. Good luck. Really. No kidding.

I know they each have operations research whizzes who do some great stuff. I studied their efforts in my research. One said that they developed its schedules using linear programming which has its limits for solving big, complex problems. The problem was so big, they broke it into pie slices. Solutions for routing in the center of the slice were great but the closer to the slice edge they got, the less good they were.

I was in discussions with some planners at the other carrier and they were very enthusiastic about what I had to say UNTIL I asked for a non-disclosure agreement. Then, everything went silent.

I strongly believe in my idea and would like to see one of the two implement it.

No. In fact, I recently chided someone posting on the internal board at my carrier for worrying about a spate of 2.0-2.9 earthquakes near one of our hubs.

I'm currently enjoying 7 weeks of white space on my calendar with full pay by "optimizing" 2 weeks of vacation and "optimizing" my trips on the front and back end of the vacation. "Optimization" works just fine "as is" for me right now.
