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 gothered the following data relating to activities over the last four months: Month 2 1 4 135 196 57 113 174 50 107 96 38 90 8 days 10 7 day 5 days 20 4 days 10 31 Quality control measuresi Number of defects Number of warranty claim Number of customer complaint Material control must Purchase order load time Sarap as a percent of total cost Machine performance seasures Machine downtime as a percentage of availability Use as percentage of availability Getup time (hours) Olivery performance measuren Throughput time Manufacturing ayole officiency (MC) Delivery cycle time percentage of on-time deliveries 45 24 961 B 35 931 10 30 900 11 86 12 7 7 2 971 ? 7 961 2 7 7 930 7 7 7 908 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 Wait time per order before start of production Inspection time per unit Process time per unit Queco time per unit Move time per unit 8.0 0.9 2.4 10.4 0.6 2.3 13.0 0.8 11.0 0.8 2.2 5.4 0.6 1.9 6.6 0.2 0.4 0.6 Required: 1-a. Compute the throughput time for each month 1-5. 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 thatin 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.
