Ch. 10 Prob. 20, Ch. 11 Prob. 18 20)1. Throughput time Month 1= 0.6+0.7+0.5+3.6 = 5.4 Month 2= 0.5+0.7+0.5+3.6 = 5.3 Month 3= 0.5+0.4+0.4+2.6 = 3.9 Month 4= 0.4+0.3+0.5+1.7 = 2.9 MCE Month 1= 0.6/5.4 = 0.11111 Month 2= 0.5/5.3 = 0.094 Month 3= 0.5/3.9 = 0.128 Month 4= 0.4/2.9 = 0.138 Delivery Cycle Time Month 1= 9.6+5.4 = 15 Month 2= 8.7+5.3 = 14 Month 3= 5.3+3.9 = 9.2 Month 4= 4.7+2.9 = 7.6 2. The trend over the four months is in a positive direction. The MCE needs to be improved. This can be done by using faster transportation, better inspection systems, and a better queue system. 3. a) Throughput time= 0.4+0.3+0.5 = 1.2 MCE= 0.4/1.2= 0.333 b) Throughout time= 0.5+0.4= 0.9
