Question

The following data represents the manufacturing lead-time for customized booklets produced at a printing house using 2 work centers A-printing and B-binding and assembly. An order for 5000 custom booklets is received and released to the production floor. Calculate and provide answer as follows:i) Total manufacturing lead time for the order. (Convert answer to hours and minutes)

ii) Actual percentage of time the order is running.
*Note production quantity and time within each work center. A - Set-up time 2-hours A - Run time/1000 units 2-hours Move time A to B 30-minutes B - Set-up time 4-hours B - Run time/500 units 3-hours Wait time between A & B 8-hours Queue time at work center B 30-minuts Move time to storage 1-hour

Answer 1

The total manufacturing lead time for the order is 20 hours and 30 minutes. The actual percentage of time the order is running is approximately 25.6%.

Step-by-step explanation:

i) To calculate the total manufacturing lead time for the order, we need to add up the set-up time, run time, move time, wait time, queue time, and move time to storage.
Set-up time for A is 2 hours, run time for A is 2 hours (for 1000 units), move time from A to B is 30 minutes, set-up time for B is 4 hours, run time for B is 3 hours (for 500 units), wait time between A & B is 8 hours, queue time at work center B is 30 minutes, and move time to storage is 1 hour. Adding all these times together, the total manufacturing lead time for the order is 20 hours and 30 minutes.

ii) To calculate the actual percentage of time the order is running, we can divide the total run time (2 hours for A and 3 hours for B) by the total manufacturing lead time (20 hours and 30 minutes). This gives us a percentage of 25.6%. So, the actual percentage of time the order is running is approximately 25.6%.
