Tombro Industries is in the process of automating one of its plants and developing a flexible manufacturing system. The company is

finding It necessary to make many changes in operating procedures. Progress has been slow, particularly in trying to develop new

performance measures for the factory.

In an effort to evaluate performance and determine where improvements can be made, management has gathered the following data

relating to actlvities over the last four months:

The president has read In Industry journals that throughput tIme, MCE, and delivery cycle time are Important measures of performance,

but no one is sure how they are computed. You have been asked to assist the company, and you have gathered the following data

relating to these measures:

Required:

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

$1-$b$.$ Compute the manufacturing cycle efficlency $($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.
