Average Half Width # Patients in System (WIP) # Patients in Queue Registration Queue Group 1 Queue Group 2 Queue Waiting Time Registration Queue Group 1 Queue Group 2 Queue Resource utilization Nurse Room 1 Room 2 Room 3 Doctor 1 Doctor 2 Doctor 3 Interpretation What is the bottleneck resource in the system? Why ? What are the areas that need improvement from system performance viewpoint? Provide a detailed discussion and feedback. Problem 3 Ceiling Fan Production System (30pts): Kits of ceiling fans arrive at an assembly system with TRIA (2, 5, 10) interarrival times (all times are in minutes). There are three assembly operators and the kits are automatically sent to the first available operator for assembly. The fan assembly time is operator dependent as given below: Operator Assembly Time 1 TRIA (15,18,21) 2 TRIA (16,19,22) 3 TRIA (17,20,23)

Upon completing of the assembly process, the fans are inspected with approximately7% being found defective. A defective fan is sent back for repair process, which will be performed at the same assembly process. The defective fans have a higher priority than the new arriving fans for assembly. Build and run your model for 24,000 mins with 2000 mins warm-up time and 10 replications. The system working time is 8 hours a day. Report the followings with sufficient interpretations. # WIP Total time per entity Average waiting time and number waiting Average resource utilizations Proportion of defectives to total output Note: If you cant model the operator dependent assembly process or defective units re-process at the same assembly fully, make sure to submit a working model and results to receive partial credits.

Simulation with Arena |(6th Edition) Chapter 4, Problem 28E Show all steps: := Bookmark Problem Modify your solution from Exercise 4-27 to include lunch breaks for the doctors who staff the examination rooms. There are three doctors on duty for the first 3.5 hours of each 8-hour shift. For the next 90 minutes, the doctors take rotating 30-minute lunch breaks, resulting in only two doctors being available at any point during these 90 minutes. If all three doctors are busy with patients when the 90-minute lunch period begins, they wait until the first patient among the three is done, and that doctor takes the first 30-minute lunch break; each doctor gets a full 30-minute lunch, so if the 90-minute lunch period starts a little late, it also ends that much late. After all the lunch breaks end, all three doctors are available until the end of their 8-hour shift, at which point the second 8-hour shift begins with the same staffing and lunch (maybe call it dinner) rules. Note that the 8 hours in a doctor's shift include the 30-minute lunch break.
