Debby Correia Week 5 Assignment
Stella can handle about ten customers per hour at her one-person comic book store. The customer arrival rate averages about six customers per hour. Stella is interested in knowing the operating characteristics of her single-channel, single-phase queuing system.
EXPLANATION: λ = 6/hr μ = 10/hr ρ = 0.6
Ls = 1.5 customers Lq = 1.5 − .6 = 0.9 customers
Ws = 1.5/6 = .25 hrs. = 15 min. Wq = .9/6 = .15 hrs. = 9 min.
***I used the model of the example in the book, chapter 12 (page 429)
