Answer:
Below is the solution to the given problem
Explanation:
a. What is the average number of customers waiting?
With one barber and exponential service, this system fits Model 1 in the text. λ = 3.000 per hour (given), μ= 60/17 = 3.529 per hour.
You are looking for Lq here.
Lq = λ / μ(μ – λ) =
/3.529 (3.529 – 3.000) = = 4.82 customers
b. What is the average time a customer waits?
Wq = Lq/λ = 4.82/3.00 = 1.607 hours = 96.40 minutes
c. What is the average time a customer is in the shop?
You are looking for Ws here, and need to calculate Ls first.
Ls = λ / μ(μ – λ) = 3.00/3.529 – 3.000= 5.671
Ws = Ls/λ = 5.671/3.00 = 1.890 hours = 113.4 minutes
d. What is the average utilization of Benny's time?
ρ = λ/μ = 3.00/3.529 = 0.85 = 85.0%
Answer:
Nami's indifferent in 3 points that lie on the different curve, the three poits
that are mentions are -
1. Point C - 5 soda and 6 pizza slices
2. Pont E - 2 soda and 11 pizza slices
3. Point F - 14 soda and 3 pizza slices.
Do check the graph,
In which x-axis is for pizza slices and Y-axis is for soda counts. The all three points are represented as E -( 2, 11), C - (5, 6), and F - ( 14, 3).
