Required:

$1-$a$.$ Compute the throughput time for each month.

$1-$b$.$ Compute the manufacturing cycle efficiency $($MCE$)$ for each month.

$1-$c$.$ Compute the delivery cycle time for each month.

$3-$a$.$ Refer to the inspection time, process time, and so forth, given for month $4.$ Assume that in month $5$ the inspection time, process time, and so forth, are the same as for month $4,$ except that the company is able to completely eliminate the queue time during production using Lean Production. Compute the new throughput time and MCE.

$3-$b$.$ Refer to the inspection time, process time, and so forth, given for month $4.$ Assume that in month $6$ the inspection time, process time, and so forth, are the same as in month $4,$ except that the company is able to eliminate both the queue time during production and the inspection time using Lean Production. Compute the new throughput time and MCE.
