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 activities over the last four months: 7 day 1 30 Month 2 Quality control measures Number of defects 185 163 124 91 Number of warranty claims 46 39 30 27 Number of customer complaints 102 96 79 Material control measures 58 Purchase order lead time Serapan percent of total coat days 5 days day Machine performance measures 11 23 Machine downtime as a percentage of availability 38 40 40 68 Uoo as a percentage of availability 921 191 Setup line (hours) 10 17 Delivery performance measure 12 Throughput time 7 Manufacturing cyele efficiency (MC) 2 2 2 Delivery eyale time 2 Percentage of on-time deliveries 951 920 890 The president has read in industry journals that throughput time, MCE, un 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: 950 7 2 Average per month daya 1 2 3 Want time per order before start of production Inspection time per unit Process time per unit Queue time per unit Hove time per unit 11.5 0. 2.0 4.4 12.0 0.7 9.0 0. 2.1 2. 0.3 16.0 0. 6.0 0. 7.0 0.5 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, 3-6. Refer to the inspection time, process time, and so forth, given for month 4. Assume that in month 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. 3-6. 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.
