Mgmt 361 Homework #1 Question 1 A process has 3 stages as shown. P1, P2 etc. are the labels for the machine and the other number in the box is the machine capacity in units per hour. (a) What is the cycle time for stage 1 (in minutes per unit)? (b) What is the cycle time for stage 2 (in minutes per unit)? (c) What is the cycle time for stage 3 (in minutes per unit)? (d) What is the bottleneck stage: (e) If you can add only one machine in parallel at the bottleneck stage, what should be the largest cycle time for the new machine so that you increase the process capacity as much as possible? Question 2 Use the data from problem 4, page 66 from the textbook (“Rockness Recycling…”) to answer the following. Assume a 40 hour work week to answer all questions. (a) What is the capacity of Step 1 (stage) per week? (b) What is the capacity of Step 2 (stage) per week? (c) What is the capacity of Step 3 (stage) per week? (d) What is the capacity of Step 4 (stage) per week? (e) What is the capacity of Step 5 (stage) per week?

Unformatted text preview: (f) What is the bottleneck? (g) If the process needs to handle 2000 students per week, what should be the largest processing time per student (in minutes) at the bottleneck stage? Question 3 Consider the three-stage process shown here with hourly capacity of each machine. a) What is the cycle time at Stage 1? b) What is the cycle time at Stage 2? c) What is the cycle time at Stage 3? d) Which stage is the bottleneck? e) What is the minimum TPT? = Suppose two new machines are added to the process (in parallel to other machines at a stage): P4 at stage 2 (with cycle time = 10 min / unit) and M3 at stage 3 (with cycle time = 6 min / unit). f) What is the process productivity? (There is one worker per machine). Question 4 Consider the three-stage process shown here, what is the minimum TPT? Question 5 Consider the four-stage process shown here with the processing times in minutes(: A1: 9, A2: 9, M1: 6, D1: 5, X1: 8 and X2: 12). What is the minimum TPT?...
