assignment 4

b) Given two reliability functions of two systems: R(1 ), =e-012. 120 1000 -1 R(1 ) 2 OSIS1000 1000 Determine: i) Cumulative distribution function (2 marks) ii ) Hazard rate function (4 marks) 111) The MTTF (2 marks) iv) The Reliability if the operating time is 400 hours (2 marks) v ) Compare the reliability and MTTF for the systems [1 Mark] ) A microwave transmitter has a constant failure rate of 0.00034 failures per hour. Determine i ) The MTTF (2 marks) ii) The tmed (2 marks) The reliability R(t) for 30 days of continuous operation (2 marks) iv) The design life if the reliability is 0.95 (2 marks)\f
