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.

Tombro Industries is in the process of outomoting one of its plants and developing a flexible manufacturing system. The company's 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 con be made, management hos gathered the following data relating to activities over the last four months: Month 2 3 4 186 47 103 164 40 97 125 31 80 92 20 59 10 days 9 days 1 days 20 20 30 5 days 68 Quality control measures Number of defects Number of warranty claims Number of customer complaints Material control measures: Purchase order lead time Serap as a percent of total cost Machine performance measures Machine downtime as a percentage of availability Use as a percentage of availability Setup time (hours) Delivery performance measures Throughput time Manufacturing cycle officiency (MCE) Delivery cycle time Percentage of on-time deliveries 961 10 50 930 12 50 900 13 064 14 ? ? ? 7 2 ? 960 7 2 7 931 7 7 7 900 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: Average per Month in days) 2 3 4 1 13.0 0.8 15.0 0.8 1.0 1.6 10.0 0.9 2.8 3.1 0.2 12.4 0.8 2.3 4.2 0.3 wait time per order before start of production Inspection time per unit Process time per unit Queue time per unit Move time per unit 7.3 5.3 0.3 0.9 Int 6 Next >
