Dynamic Control of a Queue with Adjustable Service Rate
2001
Operations Research
Preserved Fulltext
The queue length evolves as a birth-and-death process with constant arrival rate λ = 1 and with state-dependent service rates µ n that can be chosen from a fixed subset A of [0, ∞). ...
We consider a single-server queue with Poisson arrivals, where holding costs are continuously incurred as a non-decreasing function of the queue length. ...
As is customary, we use the term "queue holding cost = h n n = number of jobs in system Choose service rate µ n for each state n cost of effort = c(µ n ) Figure 1 : A Queueing System with Adjustable Service ...
