Scenario A: The figure below shows the process for paying tuition at a major university (link to photo provided here). Students are provided their bill for the next term for review, then routed to different tables for questions to be answered before finally paying their tuition at E. The numbers in parentheses are the time in minutes for each step of the process. Unless otherwise noted, each stage can handle 1 student at a time. The numbers in parentheses are the time in minutes for each step of the process. C (6) A (2) B (5) D (10) E (4) Suppose no lines/queues are permitted anywhere in the process (i.e., blocking can occur). If Task B routes students to the first available task (C or D, each of which performs an identical task). Which Task(s) would experience blocking? Check all that apply. A B C D E D E A Refer to Scenario A: Suppose no lines/queues are permitted anywhere in the process (i.e., blocking can occur). If Task B routes students to the first available task (C or D), which Task(s) would experience starvation? Check all that apply. C B Refer to Scenario A: Suppose no lines/queues are permitted anywhere in the process (i.e., blocking can occur). If Task B routes students to the first available task (C or D), what is the actual throughput for the entire sequence (i.e., at what rate will students exit task E, in students per minute)? O.10 .167 .2 .25 2 O 5 O 6 10 4 .5 Refer to Scenario A. Suppose you added a 2nd worker to the paying tuition stage (E), enabling it to handle 2 students at a time. The new worker works at the same rate as the original person stationed at E. What would the throughput time for the A-B-C-E routing be now? Answer in customers and/or minutes. 2 4 13 15 17 O 19 27 Following the previous question, what would the throughput capacity of Task E be after adding a second worker at station E? Answer in customers and/or minutes. Pick the closest answer. .25 .5 .75 1 2 4 8 Refer to Scenario A: For this question, suppose that queues / lines are now permitted anywhere in the process. If 75% of students are routed through C and 25% are routed through D, what task is the bottleneck in the A-B-D-E process route? OB OD Refer to Scenario A: For this question, suppose that queues / lines are permitted anywhere in the process. If 75% of the students are routed through task C and 25% are routed through task D, what is the utilization for Task C? Pick the closest answer. 80% 90% 100% 110% O 120% Refer to Scenario A: Suppose that 75% of students are routed to task C, and 25% to D, and queues/lines are permitted anywhere in the process. You could hire one additional worker for any single task (doubling throughput capacity at that task). Assigning the new worker to which task would have the greatest impact on the throughput for the entire process (i.e., the rate at which students exist task E). O B D
