OldTests.docx Page 1 MGMT 36100 Old Tests For three tests given during each semester, two sample tests (A and B) are included. Only numerical problems from tests (no descriptive questions) given during last academic year are included. Remember that the final exam contains questions from Part 1 and 2 also. Add extra rows to tables as needed while solving Test 1 - A Question 2 [20 points: 5, 4, 3, 8] Consider the process shown to the right. There is one worker per machine. Per unit processing times in seconds are : Stage 1: P1 – 10, P2 – 15, P3 – 12 Stage 2: M1 – 10, M2 – 5. Stage 3: R1 3 Part A: Calculate stage capacities in units per minute. Part B: What is the hourly process productivity ? Part C: What would happen if the input rate is 20 units per minute? Write brief explanation. Part D: You want to maximize the capacity of the system and you have three machines available: P4 (for stage 1), M3 for stage 2 and R2 for stage 3. You can select only 2 machines. a. Which two machines will you select? Why? b. These machines can be bought with any capacity, smaller the capacity, less expensive the machine . What should be the capacity of each new machine you selected if you want to spend minimum amount of money? Question 3 [20 Points: 5, 10, and 5] Part A: One insurance company claimed that they take less than six months to complete the review of complex claims cases. They generally complete 300 cases per year. On an average, they had 450 pending cases. Is the estimate of average time to complete the review realistic? Justify your answer. Part B: A product has 4 sequential tasks shown to the right. The plant operates in a single shift (7.5 hours) and is set up with three departments D1, D2 and D3. Each worker in D1 will work only on Task 1. Each worker in D2 will work only on Task 2. Each worker in D3 will perform Task 3 and Task 4. We would like to design plant capacity of 7800 units per shift . How many workers do we need in each department? Part C: A process flow diagram is shown to the right. All times are in minutes. Three components X, Y and Z are respectively processed at stages 1, 2 and 3. The three components are then assembled into the final product at stage 4. What is the hourly capacity of Stage 3? What is the minimum TPT? Explain briefly.

OldTests.docx Page 2 Question 4 [20 Points: 5, 3, 9, and 3] Part A : For the precedence diagram shown here, task times are in seconds. Calculate rank positional weights (RPW) for all tasks. (no need to show detailed calculations) Part B: What should be the target cycle time (must be an integer number in seconds /unit) if we need to produce at least 470 units per shift (of 7 hours ) ?
