Percentage of on-time deliveries 95% 94% 91% 88% 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) 1 2 3 4 Wait time per order before start of production 10.0 12.3 13.0 15.0 Inspection time per unit 0.8 0.7 0.7 0.7 Process time per unit 2.8 2.4 2.2 1.1 Queue time per unit 3.1 5.2 6.7 8.6 Move time per unit 0.3 0.4 0.4 0.6 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.
