tombro Industries is in the process of automated 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 activities over the past four months

The president has read in industry journals that throughput time MCE and delivery cycle time are important matters 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

1.a. compute the throughput time for each month

1.b. Computer manufacturing cycle efficiency (mce) for each month

1.c. Computer 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 in month 4 except that the company is able to completely illuminate the queue time during production using lean production. compute the new throughput time and mce.

3.b. Referred to the inspection time crisis time and so forth given for a month 4. assume the 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. compjte the new throughout time and mce.
