3.1 Describe measures to be taken to ensure a bottleneck operation is not disadvantaged by a bad quality part/component. 3.2 Discuss the root causes of bottlenecks in a manufacturing environment. 3.3 Fifty air filtration systems designed for aviation were operated for 12,000 hours at a test facility in Boksburg. The following filtration systems failed during the test: one -5. failed at 8000 hours, two failed at 10,100 hours, another one failed at 11,500 hours and two more failed at 11,890 hours. Calculate: 3.3.1 The percentage of failures, FR(\%). 3.3.2 The number of failures per unit of time, FR(N). 3.3.3 The mean time between failures 3.4 Determine the reliability of the system below
