Sue Helms Appliances wants to establish an assembly line to manufacture its new? product, the Micro Popcorn Popper. The goal is to produce

five

poppers per hour. The? tasks, task? times, and immediate predecessors for producing one Micro Popcorn Popper are as? follows:

Task Performance Time?(mins) Task Must Follow Task Listed Below A 9 – B 11 A C 9 ?A, B D 11 ?B, C E 8 C F 4 ?D, E

A C F B E D In the diagram, there are 6 circles labeled using the letters from A to F. There are 8 of arrows, and each arrow connects one circle to another circle. The arrows are situated in the following manner: A to B, A to C, B to C, C to D, B to D, C to E, D to F, and E to F.

?a) The theoretical minimum number of

workstations=11

?(round your response up to the next whole? number).

?b) The assignment of tasks to workstations should? be:?(Hint: Number workstations sequentially in terms of precedence relationships and combine any applicable? tasks.)

Task	Workstation? #

B	? Station 2 Station 5 Station 3 Station 1 Station 6 Station 4

C	? Station 2 Station 5 Station 6 Station 4 Station 1 Station 3

D	? Station 5 Station 1 Station 2 Station 3 Station 6 Station 4

E	? Station 4 Station 3 Station 1 Station 5 Station 2 Station 6
