Question
Chapter D, Problem 20P
a)
Summary Introduction
To determine: The number of doctors required to be on duty.
Introduction: The mathematical study which analyses the causes of delay in the waiting line is known as queuing theory. The theory examines all components in the waiting line such as arrival process, service process, and number of servers, system and customers.
b)
Summary Introduction
To determine: The condition of the hospital when only one doctor is available between 9A.M and 3P.M.

QUESTION 5
A post office has a counter for customers' drive-through to get the services. The design of the
drive-through lane allows for unlimited queue length. The arrival and service rate are Poisson
distributed with A= 20 customers per hour arriving on average and u=25 customers per hour can
be served on average.
a) Compute the average number of arrivals.
b) Compute the average time a customer waits.
c) Compute the average number of arrivals in the system.
d) Compute the average time a customer is in the system.
e) Compute the probability that less than or equal to 3 customers are in the system.
f) If the single counter for the customer drive-through has been replaced with the automatic
operation, service rates are constant with A= 20 and u =25. Compute (a), (b), (c) and (d).
Q.11 An example of a leading performance measure is:
a.Number of new customers
b. Average response time for service call

- QUESTION 5 Regional Airlines is establishing a new telephone system for handling flight reservations. During the 10:00 AM to 2:00 PM time period, calls to the reservation agent occur randomly at an average rate of one call every 3.75 minutes. Historical service time data show that a reservation agent spends an average of 3 minutes with each customer. The waiting line model assumptions of Poisson arrivals and exponential service times appear reasonable for the telephone reservation system. At a planning meeting, Regional's management team agreed that an acceptable customer service goal is to answer at least 75% of the incoming calls immediately. During the planning meeting, Regional's vice president of administration pointed out that the data show that the average service rate for an agent is faster than the average arrival rate of the telephone calls. The vice president's conclusion was that personnel costs could be minimized by using one agent and that single agent must be able to…arrow_forwardQuestion related to gueing theory don't copy In a restaurant, two types of foods are available. Arival rate of customers is 26 per hour Poisson and average service time is 6 minutes exponential. The arriving customers can be served in three ways. The first way is to open two separate counters for the two types of foods. The second way is to pool the services, and offer both types of foods in both the counters. The third way is to open a large number (0) of self-service counters for the customers. Which way will lead to the maximum busy period of the system? wwmarrow_forwardQUESTION 1 A multiple channel queuing system with a Poisson arrival rate, and an exponential service time distribution has an average arrival rate of 2.5 customers per hour and an average service time of eighty minutes per customer.
