Frequency and duration technique
2. The system has 2 components per series, if one component fails the other cannot fail while repairing if component failure and repair rates are µ1= µ2 = 0.1 times/year and µ1= µ2= 365. Repair/year Find the probability of failure, frequency of failure, and average system downtime.
3. Find the same index as in 2 if both components are identical and one is used as a backup with an average install time 1 Hours.

4. Reliability of Systems - Take n components to have failure times Ti, T2, ..., Tn If we construct a complex system out of these distribution of the failure time T of the entire svstem in terms of the distributions of Ti, T2, ..., Tn. There are two basic networks. In a series hookup, the system fails as soon as any one of the components fails. Hence T - min(T1, T2, ...,Tn). In a parallel hookup the system is operational...

Hello, I need help for this problem. A system is composed of N identical components. Each independently operates a random length of time until failure. This failure time is exponential with rate λ. When a component fails, it undergoes repair. The repair time is random, exponential with rate µ. The system is said to be in state n at time t if there are exactly n components under repair at time t. This process is a birth and death process....

Example 1: Electronic components of a certain type have a length life (in hours) X, that follows the exponential distribution with probability density given by f(x) = (1/100)e ^ [(− 1/100)x] , x > 0. a. Suppose that 2 such components operate independently and in series in a certain system (that is, the system fails when either component fails). Find the density function for the length of life of the system. b. Suppose that 2 such components operate independently and...
