Optimal Service Speeds in a Competitive Environment [PDF]

open access: yesManagement Science, 1992
This is a study of the economic behavior of vendors of service in competition. A simple model with two competing exponential servers and Poisson arrivals is considered. Each server is free to choose his own service rate at a cost (per time unit) that is strictly convex and increasing.

Stability of the Greedy Algorithm on the Circle [PDF]

open access: yes, 2017
We consider a single-server system with service stations in each point of the circle. Customers arrive after exponential times at uniformly-distributed locations. The server moves at finite speed and adopts a greedy routing mechanism.
