note: i dont want to answer the question below i want you to explain only my questions i will ask now...

b1=10

62=8

b3-a=15

b3-b=10

b4=9

i want to ask... now in question a...when i want to

calculate the time needed.. i should take the

longest way?

i mean 10 + 8 +15 + 9=42

or i need to take the average in b3 then calculate

them

10+8 +(15+10)/2 +9 = 39.5

or calculate the lower and upper bound...the is upper i calculate it up

the lower i will take the lowest time in b3

SO

10+8+10+9=37

then take the average from upper and lower bound

(37+42\/2 =39.5 or what exactly??

other question.about the bottle neck and waiting

time..if i assume that b1 which is the first step or

process is the lowest capacitance which is the

highest step or process takes time i can say that it's

the bottle neck and the waiting time is on it?

because the first process isn't from the original

processes it's actually the process that from it the customers come on to the other processes b2,b3-a....

i say assume that b1 (first process or step) is the

highest time needed in all processes and for sure it will be the lowest capacitancecan i answer that it is the actually bottle neck and the waiting time will be in it?

or he should give me more informations about

what is before b1 so i can say if there is waiting

time on it or no.

if you don't understand my question i want you to see question b and d and assume b1 is the highest process takes time which is the lowest

capacitance and answer me.

for the question the maximum customers per

hour depends on the bottleneck capacitance

right?

thanks you.please answer carefully i have an exam,and i want right answers

Q3: (8 pts): XY Barbershop has two barbers available to cut customers' hair. Both barbers provide roughly the same experience and skill, but one is just a little bit slower than the other. The process flow in figure shows that all customers go through steps B1 and B2 and then can be served at either of the two barbers at step B3. The process ends for all customers at step B4. The numbers in parentheses indicate the minutes it takes that activity to process a customer. a. How long does it take the average customer to complete this process? b. What single activity is the bottleneck for the entire process? Explain why. c. How many customers can this process serve in an hour? Explain why. d. Where would you expect customers to experience waiting lines? Why? (15) 61 (10) B4 C Payior 83-b
