arrivals/time period = | λ= | 1/85 | /minute | ||
served/time period= | μ= | 1/15 | /minute |
a)
average number in queue Lq = | λ2/(μ(μ-λ))= | 0.0378 |
b)
average number in system L = | λ/(μ-λ)= | 0.2143 |
c)
probability of 0 wating in system = | (1-λ/μ)*(λ/μ)0 = | 0.8235 |
d)
average time spend in queue Wq = | λ/(μ(μ-λ))= | 3.21 minute |
e)
average time spend in system W = | 1/(μ-λ)= | 18.21 minute |
