In this paper, we establish two preservation results of additive convexity for a class of optimal transformation problems and a class of optimal disposal problems. For both classes of problems, there are multiple resources and our results show that if these resources have different priorities to...

We study the dynamic ambulance dispatch problem in emergency medical services, in which a decision-maker sequentially observes call arrivals and decides which unit to dispatch to service the call, where the service times follow independent and heterogeneous distributions for each...
