Question 1
 
Case 9.2 A manufacturer using a kanban system has had problems with high inventory levels of one of the component parts it makes. Daily demand for the part is 3000 units, average waiting time during production is 0.20 day, processing time is 0.10 day per container, and a container holds 150 pieces. Use the information in Case 9.2. How many kanban containers would be required if a 10% policy variable is used?
Answer
Three or fewer
Four or five
Five or six
Six or seven
5 points
Question 2
 
An assembly line has to perform 10 work elements, whose time requirements follow. An operations analyst has found a solution using some heuristics. The solution follows. If the cycle time of the line is 90
seconds, what is the efficiency of the assembly line?
Answer
Less than 85%
Greater than 85% but less than 90%
Greater than 90% but less than 95%
Greater than 95%
5 points
Question 3
 
Figure 8.5 Use the information in Figure 8.5. If each task has a work time of one minute, what is the theoretical minimum cycle time?
Answer
There is no minimum cycle time.
1 minute
8 minutes
The cycle time cannot be determined with the information given.

Question 4
 
Given the following data about an assembly line and the knowledge that we are trying to attain an output rate of 40 units per hour, what is the theoretical minimum number of stations?
Answer
Four or fewer stations
Five stations
Six stations
Seven or more stations

Question 5
 
Table 8.2 Balance the following lines for an output rate of five pieces per hour. The times are in minutes (not seconds). Use the information from Table 8.2. The highest efficiency line balance is:
Answer
Less than 89%.
More than 89% and less than 91%.
More than 91% and less than 93%.
More than 93%.
