I was working through some VRP literature today and was wondering if there was a VRP formulation that included, say, acceleration times in the cost matrix calculations. Say, for example, I had 3 cities [A, B, C]. the distance between A and C is the same distance as the route between A to B to C. However, the choice to stop at B and service B enroute to C would exceed the cost of going from A to C directly (let's assume a zero service time).

i.e. t_{a,b} + t_{b,c} >= t_{a,c}

I figured it would be fine to calculate this "acceleration factor" in a time/cost matrix, but you never know if something explicitly exists out there and if it's better.

You are optimizing something, right? What is your objective and how are you variables defined?
