RDO works just fine.
To make ORION work, a number of things would have to happen. It would have to factor in the correct time window for my scheduled pickups, as well as a realistic allowance for how long it actually takes to load 2 full pallets of 40-pound cases of wine into a package car. Major corrections would also have to be made to the flawed map that it was originally based on, which has me using "roads" that show up on Google Earth but that are actually private tractor paths through vineyards or that are otherwise impassable. Depending on how many routes in my loop get dispatched, it can also have me delivering to several schools during or immediately after dismissal time. And these are only the problems that I am aware of, I'm sure there are others.
The bottom line is that I don't need ORION and since my route is desirable enough that my relief drivers exercise their seniority in order to bump junior drivers off of it, they don't need it either. And the point is moot anyway, since the type of fundamental changes that would need to be made to my ORION solution in order to make it work will never happen.
