solved ::

Parts arrive to a manufacturing system uniformly between 4 and 8 minutes. 1st part arrives after expo(3) minutes. The parts are then are processed by 3 stations in series each has a dedicated worker, each station has a processing time equal to expo(3.3) minutes. Then the parts are inspected, inspection times takes exactly 220 seconds, the inspection machine can inspect up to 10 parts simultaneously. 90% of the parts inspected are considered as good and shipped, the remaining need rework. Rework station has 2 operator, each fixing a part, each part takes between TRIA(1,3,10) minutes. Run the system for 10 replications, each replication for 200 hours, then SELECT THE CORRECT ANSWERS ONLY. A In theory, there is no need for an extra worker at the rework station B The rework station fixed fewer than 250 parts The total time for products that do not require rework is about 20.8 minutes. D The average inspection machine queue is 0.32 parts E) The utilization for the machines is between 54%-56% F) The 95% Confidence Interval for the WIP is (3.265-3.405) parts G The average total time is about 20 minutes. H The average parts waiting time is less than 5 minutes. The maximum waiting time for the 3 machines is about 1.2 hours System throughput is about 15 part /hour Question 2 O Points I declare that I will not/ did not cheat in this exam.
