An assembly line with 17 tasks is to be balanced. The longest task is 2.4 minutes, and the total time for all tasks is 18 minutes. The line will operate for 450 minutes per day. a. What are the minimum and maximum cycle times? (Round your answers to 1 decimal place.) Minimum cycle time minutes Maximum cycle time minutes b. What range of daily output is theoretically possible for the line? (Round your answers to 1 decimal place. Enter the smaller value in the first box and the larger value in the second box.) Range of output to units/day c. What is the minimum number of workstations needed if the maximum output rate is to be sought? (Round up your answer to the next whole number.) Minimum number of workstations d. What cycle time will provide an output rate of 125 units per day? (Round your answer to 1 decimal place.) Cycle time min/cycle e.

Each would have the same labor and materials costs (food, serving containers, napkins, etc.) of $2.00 per sandwich. Sandwiches sell for $2.80 each in all locations. Rent and equipment costs would be $5,450 per month for location A, $5,725 per month for location B, and $5,975 per month for location C. a.

An assembly line with 17 tasks is to be balanced. The longest task is 2.4 minutes, and the total time for all
tasks is 18 minutes. The line will operate for 450 minutes per day.

a. What are the minimum and maximum cycle times? (Round your answers to 1 decimal place.)




Minimum cycle time minutes

Maximum cycle time minutes


b. What range of daily output is theoretically possible for the line? (Round your answers to 1 decimal
place. Enter the smaller value in the first box and the larger value in the second box.)

Range of output to units/day

c. What is the minimum number of workstations needed if the maximum output rate is to be sought?
(Round up your answer to the next whole number.)

Minimum number of workstations

d. What cycle time will provide an output rate of 125 units per day? (Round your answer to 1 decimal
place.)

Cycle time min/cycle

e. What output potential will result if the cycle time is (1) 9 minutes? (2) 15 minutes?
