Assignment # 4 Due: Mon November twelfth ‐ your five: 00 EVENING

(a)  A study‐aid workplace manned with a graduate college student has been set up to answer student's questions and help in operating problems within your OM program. The desk is staffed eight several hours per day. The dean really wants to know how the facility is working. Statistics show that learners arrive at a rate of four each hour, and the syndication is approximately Poisson. Assistance time averages 5 minutes, distributed significantly. Assume population and series length may be infinite and queue self-discipline is FCFS. Using this details, answer the next questions. i. Calculate the percent of utilization of the graduate college student

P= 4/6 sama dengan 2/3 sama dengan. 6667 percent utilization

ii. Determine the typical number of pupils in the program

λ= 4 hourly

μ= 6 pupils helped one hour

Ls= 4/ 6-4 = 4/2 sama dengan 2 pupils in the system on average.

3. Calculate the average time in the machine

Ws= 1/ 6-4 = ½ =. 5 hours common time in the machine

iv. Understand the possibility of four or even more students becoming in line or perhaps being dished up

P0= 1 – 4/6 sama dengan 1- 2/3 =. 33 probability that there are 4 or maybe more students staying in line or being dished up. v. Ahead of a test, the arrival of pupils increases to five hourly on the typical.  Compute the typical number of students waiting below this scenario.

Lq= 4^2 / 6 (6-4) sama dengan 16/ 12= 1 . thirty-three student browsing line on average.

(b)  What are the 3 characteristics of the waiting‐line system? 1 . Arrivals or advices to the system: these have characteristics such as population size, behavior, and a statistical distribution. 2 . Queue self-control, or the waiting around line by itself: characteristics with the queue contain whether can it be limited or perhaps unlimited long and the self-discipline of people or items in it. a few. The service facility: the characteristics contain its design and the record distribution of...
