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 Month 189 50 106 167 43 100 128 34 83 92 31 52 8 days 2x 7 days 5 days 2 3% 4 days 65 Quality control stures Number of defects humber of warranty claims er of customer complaints Puterial control reasures Purchase order lead time Scraps percent of total cost chine perforence aures: Machine downtima percentage of availability Un percentage of availability Setup time chours) Delivery performance measures: Manufacturing cycle efficiency CHCE) Delivery sytle time Percentage of on-time deliveries 5% 94% 8 65 91% le 5% 88% 11 10% 84% 12 2 > 2 2 ? ? 2 945 2 95% 91% 2 88 The president has read in industry Journals that throughpur 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) 1 2 10.1 8. 2.8 wait tim por order before start of production Inspection time per unit Process time per unit Queue tine per unit Move time per unit 11.e 0.7 1.9 5.e 2.8 2. 13.e 8.7 1.2 7.4 0.7 3.1 e. 3.4 Required: 1a Compute the throughput time for each month 1-0 Compute the manufacturing cycle efficiency (MCE) for each month 1-c. Compute the delivery cycle time for each month 3-0. 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 far 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 Complete this question by entering your answers in the tabs below.
