Compute the reliability of a system with 7 components, neading with at least 2 in full operation with the MTTF of each component being 2100 hours, after 2510 hours of operation
Correct Answer: 0.676128323
Homework Answers
mean = 2100
X = lifetime of a system
X follow exponential distribution with mean = 2100
P(X > 2510) = e^(-2510/2100)= 0.30263
Y = number of component in full operation
Y follow binomial distribution with n = 7 , p = 0.30263
P(Y >= 2 )
=binom.dist.range(7, 0.30263,2,7)
= 0.672612

module, consists of five repairable components, all of which must operate for system success. Each component performs a different function but all five share identical reliability parameters. Specifically, MTTF for each component is 100 years and MTTR 40 hours. Calculate the following for this single system module: 1) Failure rate 2) Average down time 3) Unavailability

2. Consider the reliability model given in Assignment 5 Problem 1. You have discovered that the reliabilities given there were just rough estimates. After careful analysis of historical data, you know that each component has a random time until failure that is distributed according to the following table. Ideally, this machine shop should run for the next 2 years without the need to replace any components. Mean time until failure (MTTF); Time until failure (TTF) Component Distribution Exponential Parameters MTTF:...

Problem 4 Consider the system of components connected as depicted below. The system can be thought of as being comprised of two subsystems: one with components A and B, and the other with components C and D. Components A and B are connected in parallel, therefore that subsystem works iff either A or B works. Since C and D are connected in series, that subsystem works iff both C and D work. Components work independent of each other (that is,...

7 - 22 (page 365). Spacescope Inc. has an electronic component that has a failure rate of 0.0000165 units/hour. Find the mean time to failure (MTTF). What is the probability (assume an exponential distribution) that the component wil not have failed after 15,000 hours of operation? Calculate your answer using the appropriate mathematical formula, and verify your results using Excel.
