Question

Layout

Part A

A facility is setting up an assembly line to produce 75 units per day, working 24 hours per day.

Calculate the desired cycle time in minutes per unit.

(Round up to a whole number)

Part B

Task	Time (Min)	Predecessors
A	4	-
B	3	-
C	5	A
D	5	A,B
E	3	C,D

Assume a facility is setting us an assembly line and the tasks and times are listed above. Assume the desired cycle time is 15 minutes/unit.

What is the theoretical minimum number of workstations required?

(Round up to a whole number)

Part C

A facility is setting up an assembly line.

Task	Time (Min)	Predecessors
A	4	-
B	8	-
C	3	A
D	8	A,B
E	4	C,D

Assume the desired cycle time is 16 minutes per unit.

Balance the line and assign tasks to workstations using the longest task time rule. Break ties with the most number of followers rule. (Use the process in class and the complete the chart on a separate piece of paper)

In Workstation #1 you should add the following activities in the following order:

Activity/task letter  should be added first (enter 'none' if no activity should be added here)

Activity/task letter  should be added second (enter 'none' if no activity should be added here)

Activity/task letter  should be added third (enter 'none' if no activity should be added here)

Activity/ task letter  should be added fourth  (enter 'none' if no activity should be added here)

Part D - This is a continuation of Part C and deals with workstation #2

A facility is setting up an assembly line.

Task	Time (Min)	Predecessors
A	4	-
B	8	-
C	3	A
D	8	A,B
E	4	C,D

Assume the desired cycle time is 16 minutes per unit.

Balance the line and assign tasks to workstations using the longest task time rule. Break ties with the most number of followers rule. (Use the process in class and the complete the chart on a separate piece of paper)

In Workstation #2 you should add the following activities in the following order:

Activity/task letter  should be added first (enter 'none' if no activity should be added here)

Activity/task letter  should be added second (enter 'none' if no activity should be added here)

Activity/task letter  should be added third (enter 'none' if no activity should be added here)

Activity/ task letter  should be added fourth  (enter 'none' if no activity should be added here)

Part E

Given the following layout.

Workstation 1	A	3 minutes
	C	3 minutes
Workstation 2	D	6 minutes
	E	2 minutes
	F	3 minutes
Workstation 3	G	4 minutes
	B	2 minutes

What is the actual idle time per cycle (unit)?

(Round to a whole number)

Part F

How do you determine the actual cycle time of a balanced line?

Choose the best answer.

		Divide the available time in a work day by the demand (required number of units in a day)
		It is determined by the workstation that takes the shortest amount of time.
		It is determined by the workstation that takes the longest amount of time.
		It is always the longest task/activity time.
