Dynamic Vehicle Routing - PhD Theses Couple

It is interesting to see, how some PhD candidates have managed to develop such a good team work in doing research and produced articles that are mutually beneficial for each team member's thesis. I find this unique case while I am drowning in the dynamic vehicle routing problems literature. Basically there are two approaches for tackling the problem: the OR (operations-research) approach and the decentralized (agent based) approach.
