If you're looking for problems to solve in the transportation / shipping context, one that comes to mind is estimated delivery. Try predicting the day (maybe even down to the hour) of when something will arrive at its destination once it enters your company's network. It may require feeding it the origin and destination, the product mix in the trailer, customer priority, weather conditions, time of year (peak season?), etc.

Oh yeah, I can see how this one could be doable. Has practical application too, if it can be made accurate enough.
