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 Quality control measures: Number of defects Number of warranty clains Number of customer complaints 185 46 102 163 39 96 124 91 27 58 79 Material control measurest Purchase order lead tine 8 days 7 days 5 days 4 days 38 Scrap as a percent of total cost It 2t Machine performance measurest Machine downtime as a percentage of availability Use as a percentage of availability Setup time (hours) 38 48 921 10 898 85% 12 Delivery performance measures: Throughput time Manufacturing eyele efficiency (MCE) Delivery cycle time Percentage of on-time deliveries 968 95t 921 891 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: erage per Mont in days Wait time per order before start of production Inspection time per unit Process time per unit Queue tine per unit Move time per unit 9.0 11.5 12.0 14.0 0.8 0.7 0.7 0.7 2.1 2.0 1.9 1. 2.8 4.4 6.0 7. 3 0.4 0.4 0.5 Required: 1-8. 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 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 com production using Lean Production. Compute the new throughput time and MCE inspection time, process time, and so forth, given for month 4. Assume that in month 6 the inspection time, proc 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 MC 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.
