Understanding the marginal impact of customer flexibility

We study the marginal impact of customer flexibility in service systems. We consider a queueing system with multiple parallel servers, in which a proportion of customers are flexible and can go to any server, while the remainder require service at a particular server. We show that the stationary expected waiting time is decreasing and convex in the proportion of flexible customers. We also show, for a related Inventory Model, in which servers are never idle and can build up inventory, that convexity holds in a strong sample-path sense. Our results reinforce the idea that a little flexibility goes a long way.
