Question 7

Jones Electric Motors uses a Kanban system to make motors for several garage door companies in the southeastern United States. The daily demand for motor housings used in manufacturing is 100 units. The average waiting time for a container of parts is 0.2 day. The processing time for a container of housings is 0.1 day, and a container holds 5 housings. If Jones wishes to use a 10% policy variable, how many containers are needed?

Accepted Answer

k = @#LAT-DLM& = @#LAT-DLM& =

Question 8

Firms that have highly repetitive processes and well-defined work flows of standardized items often use the pull method.

Accepted Answer

A) True 
 B)False

Question 9

Happiness, Inc. uses a Kanban system. The daily demand for the most critical part, the Smylie, is 400 units over an eight-hour production period. The average waiting time for a container of Smylies is 30 minutes. The processing time for a container filled with Smylies is 6 minutes, and a container holds 5 units. If the company wishes to use a 5% policy variable, how many containers are needed?

Accepted Answer

k = @#LAT-DLM& = @#LAT-DLM& =

Question 10

When implementing a lean system:

Accepted Answer

A)  managers can mitigate some of the effects of worker stress by judiciously using safety stocks and emphasizing material flows rather than worker pace. 
B)  management should base the reward system on production volume. 
C)  the plant layout is the only environmental characteristic that need not be analyzed. 
D)  it is critical to develop a master production schedule that changes frequently as forecasts change.
