Chapter 2: Q.11.60Q (page 288)

Question: Avis Company is a car rental company that is located three miles from the Los Angeles airport (LAX). Avis is dispatching a bus from its offices to the airport every 2 minutes. The average traveling time (round-trip) is 20 minutes.

a. How many Avis buses are traveling to and from the airport?

b. The branch manager wants to improve the service and suggests dispatching buses every 0.5 minutes. She argues that this will reduce the average traveling time from the airport to Avis offices to 2.5 minutes. Is she correct? If your answer is negative, then what will the average traveling time be?

Answer

Little's Law illustrates the relationship between a system's inventory, throughput rate, and flow time. This law states that the inventory level of a system at any given time may be calculated by multiplying the throughput rate and flow time.

The following is a mathematical depiction of Little's Law:

Inventory = Throughout rate x Flowtime

Step by step solution

01

 (a)To begin, calculate the throughput rate and flow time as follows: 

Throughputrate=1busper2minutes=60min/hr2min/bus=30bus/hourFlowtime=20min=2060min/hour=13hour


02

Calculate the number of buses that will be traveling to and from the airport. 

滨苍惫别苍迟辞谤测=罢丑谤辞耻驳丑辫耻迟谤补迟别脳贵濒辞飞迟颈尘别=30bushour脳13hour=10buses

10 buses are traveling to and from the airport.

03

(b)The average traveling time would remain is

The branch manager claims that by dispatching buses every 0.5 minutes, the company can cut the average travel time from the airport to the office to 2.5 minutes. The average waiting time for the buses would be reduced if the buses were dispatched every 0.5 minutes. It would, however, have no effect on the average journey time. As a result, it can be argued that the branch manager's reasons are erroneous.

The average journey time would stay the same at 20 minutes.

Question: An important difference between service and manufacturing operations is that customers introduce far more variability into the operations in a service system. Name at least three of the basic types of variation that customers bring to a service system.

An engineering firm retains a technical specialist to assist four design engineers working on a project. The help that the specialist gives engineers ranges widely in time consumption. The specialist has some answers available in memory, others require computation, and still, others require significant search time. On average, each request for assistance takes the specialist one hour. The engineers require help from the specialist on average of once each day. Because each assistance takes about an hour, each engineer can work for seven hours, on average, without assistance. One further point: Engineers needing help do not interrupt if the specialist is already involved with another problem. Treat this as the finite queuing problem and answer the following questions:

a. How many engineers, on average, are waiting for the technical specialist for help?

b. What is the average time that an engineer has to wait for the specialist?

c. What is the probability that an engineer will have to wait in line for the specialist?

Question: At the Children鈥檚 Hospital in Seattle there are, on average, 60 births per week. Mother and child stay, on average, two days before they leave the hospital. At the Swedish Hospital (also in Seattle), the average number of births per week is 210. Mothers and children stay in the hospital for two days on average.

a. How many new mothers, on average, are staying at the Children鈥檚 Hospital?

b. How many new mothers, on average, are staying at the Swedish Hospital?

c. The directors of the two hospitals are negotiating to unify the maternity wards of the two hospitals. They believe that by doing so they will be able to reduce the number of new mothers staying in the unified ward. Are they correct? How many new mothers will stay, on average, in the unified ward? You may assume that the average number of births and the length of stay of the new mothers will not change.

What is the effect of waiting time on a manufacturing process? Why is it good to reduce waiting time? Can it be eliminated altogether?

What are the four basic work measurement techniques?
