Unit 8:

Question 1

________ is a philosophy of operation that strives to maximize efficiency by simplifying production processes and eliminating waste.

Answer 1

Just-in-time

Question 2

True or false? The pull system involves moving materials based on actual needs at successive work centers, while the push system moves materials based on a preplanned schedule.

Answer 2

True. A pull system moves materials based on actual needs at successive work centers. A push system moves materials through the processing operations based on a schedule.

Question 3

is a method of analyzing the flow of materials, ideas, and information to understand how processes function.

Answer 3

Value Stream Mapping

Question 4

True or false? Set-up time refers to the time required to readjust a machine to make one part after using the machine to make another part.

Answer 4

True. Set-up time is the time it takes to readjust a machine or group of machines after making one particular part until acceptable units of another part are produced. Set-up time may involve changing the tooling, adjusting the equipment, checking that the new part is being made to specifications, and then readjusting the equipment if it is not.

Question 5

True or false? The single-card kanban allows more extensive control over production and inventory than the dual-card kanban system.

Answer 5

False. The major advantage of the dual-card kanban system over the single-card kanban is that it allows greater control over production, as well as over inventory, because both production and withdrawal of inventory are directly connected to need. In contrast, a single-card system bases production on a plan, which may lead to excess inventory if actual need does not match the plan.

Question 6

True or false? In a JIT environment, the master schedule is primarily only used when a firm must order items that have long lead times.

Answer 6

True. The master schedule is used in a JIT environment only when items with long lead times must be ordered. Thus, in a JIT system, the master schedule is primarily an intermediate step in reaching the final assembly schedule.

Question 7

For a JIT firm to function efficiently, inventory levels should be kept

Answer 7

Low

Question 8

When a customer is not being served or a good is not being processed, what type of waste is occurring?

Answer 8

waiting

Question 9

A JIT firm that wants to gain a competitive advantage should most likely ________.

Answer 9

reduce process variability
