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.
