Question 1 20 pts The Academic Computing Center has five trainers available in its computer labs to provide training sessions to students. Assume that the design capacity of the system is 1900 students per semester and that effective capacity equals 90% of design capacity If the number of students who actually got their orientation session is 1500, what is the efficiency of the system? O 90% 1350 students O 78.9 O 877 O 1710 students D Question 2 20 pts A work system has five stations that have process times of 5, 9, 7.11 and 8. What is the bottleneck time? Input should be an exact number for example 5 or 10). U Question 3 20 pts A work system has five stations that have process times of 5, 10, 6, 11, and 15. Find the bottleneck station. Add 2 machines to that station. What is the ndw bottleneck time? Input should be an exact number for example, 5 or 10% Question 4 20 pts Awork system has five stations that have process times of 5, 8, 5, 10, and 15. Find the bottleneck station Add 2 machines to that station. What is the throughput time of the system? Input should be an exact number (for example, 5 or 10)
