Function File: [Xl, Xu, Rl, Ru] = qnosbsb (lambda, D)

Function File: [Xl, Xu, Rl, Ru] = qnosbsb (lambda, S, V)

Compute Balanced System Bounds for single-class, open networks with K service centers.

INPUTS

lambda

overall arrival rate to the system (scalar, lambda ≥ 0).

D(k)

service demand at center k (D(k) ≥ 0).

S(k)

service time at center k (S(k) ≥ 0).

V(k)

mean number of visits at center k (V(k) ≥ 0).

m(k)

number of servers at center k. This function only supports M/M/1 queues, therefore m must be ones(size(S)).

OUTPUTS

Xl

Xu

Lower and upper bounds on the system throughput. Xl is always set to 0, since there can be no lower bound on open networks throughput.

Rl

Ru

Lower and upper bounds on the system response time.
