Which of the following is a suggestion for managing queues that is mentioned in the textbook?

Segment the customers

Using the assembly-line balancing procedure, which of the following is the required cycle time in minutes per unit if the daily production time is 480 minutes and the required daily output is 50 units?

9.6 Using equation 6.3, 480 minutes / 50 units = 9.6 minutes per unit.

For an infinite queuing situation, if the arrival rate for loading trucks is 5 trucks per hour, what is the mean time between arrivals?

See exhibit 7.11, Notations for Equations. Mean time between arrivals = 1 / Arrival rate = 1 / 5 = 0.2 hours.

Which of the following basic types of process structures is one which equipment or work processes are arranged according to the progressive steps by which the product is made?

Assembly line

The placement of which of the following is not determined by production process organization decisions?

Emergency exits

Which of the following is not considered a major work flow structure?

Fabrication

Which of the following is not a queue discipline discussed in the textbook?

Last in, first out

In the service-system design matrix, a face-to-face total customization service encounter is expected to have which of the following?

Low production efficiency

Buying a ticket for a college football game where there are multiple windows to buy the ticket at features which type of queuing system line structure?

Multichannel, single phase

Standing in line to buy a ticket for a movie where there are multiple windows to buy tickets is which type of queuing system line structure?

Multichannel, single phase

Which of the following is a characteristic that can be used to guide the design of service systems?

Services cannot be inventoried

When balancing an assembly line, which of the following is not a way to reduce the longest task time below the required workstation cycle time?

Speed up the assembly line transfer mechanism

There are many applications of poka-yokes in service organizations. Which of the following is one of the three-T's used to classify poka-yokes?

Task

According to Little's Law, which of the following can be used to estimate work-in-process inventory?

Throughput rate times Flow time

Which of the following is a suggestion for managing queues presented in the textbook?

Train your servers to be friendly

Using the assembly-line balancing procedure, which of the following is the required cycle time if the production time in minutes per day is 1440 and the required output per day in units is 2000?

Using equation 6.3, 1,440 minutes / 2000 units = 0.72 minutes per unit.

Using the assembly-line balancing procedure, which of the following is the theoretical minimum number of workstations if the task times for the six tasks that make up the job are 4, 6, 7, 2, 6, and 5 minutes, and the cycle time is 10 minutes?

Using equation 6.4, (4 + 6 + 7 + 2 + 6 + 5) / 10 = 3.

You have just determined the actual number of workstations that will be used on an assembly line to be 6 using the assembly-line balancing procedure. The cycle time of the line is 5 minutes and the sum of all that tasks required on the line is 25 minutes. Which of the following is the correct value for the resulting line's efficiency?

Using equation 6.5, [25 / (6 x 5)] = 0.833.

Which of the following is a basic type of process structure?

Workcenter
