An electrical system consists of 2 components (C1 and C2) functioning independently and are set in a parallel layout. The failure time of each component follows an exponential distribution with rate 2 every year. Identify the failure density and failure distribution of any component. Hence, calculate the probability of any component i) failing in less than 8 months. ii) surviving after 10 months.

Suppose that a certain system contains three components that function independently of each other and are connected in series, so that the system fails as soon as one of the components fails. Suppose that the length of life of the first component, X1, measured in hours, has an exponential distribution with parameter λ = 0.01; the length of life of the second component, X2, has an exponential distribution with parameter λ = 0.03; and the length of life of the...

The electrical system for an assembly line has four components arranged in two parallel subsystems as shown in the diagram below. Each of the four components (labeled 1, 2, 3, 4) are independent and each has a 10% chance of failure. Because the components are independent, the two subsystems (labeled A and B) are also independent. If one component in a subsystem fails, then the whole subsystem fails because the power cannot get through. However, because there are two subsystems,...

Consider the system of components connected as in the accompanying picture. Components 1 and 2 are connected in parallel, so that subsystem works iff either 1 or 2 works; since 3 and 4 are connected in series, that subsystem works if both 3 and 4 work. If components work independently of one another and P(component i works) 5 .9 for i 5 1,2 and 5 .8 for i 5 3,4, calculate P(system does not work).

Suppose that a system has a component whose time in years until failure is nicely modeled by an exponential distribution. Assume there is a 60% chance that the component will not fail for 5 years. a) Find the expected time until failure. b) Find the probability that the component will fail within 10 years. c) What is the probability that there will be 2 to 5 failures of the components in 10 years.

A system composes of three components. These components have constant failure rates of 0.0004, 0.0005, 0.0003 failures per hour. The system will stop working, if any one of its components fails. Calculate the following: 1. The reliability of the system at 2500 hour running time? 2. The system hazard rate? 3. Mean time to failure of the system?

The life length X of an electrical component follows an exponential distribution. There are 2 Processes by which component may be manufactured. The expected life length of the Component is 100 hrs. if process I is used to manufacture, while 150 hrs. if process II is used. The cost of manufacturing a single component byprocess I is 10 OMR , while it is 20 OMR for Process II. Moreover, if the components last less than the guaranteed life of 200...

Imagine an electrical circuit with three components wired in series. This means that if any of the components fails, then the circuit will fail. Suppose that each component has an exponentially distributed lifetime, with ?1=0.235,?2=0.129, and ?3=0.274 (units measured in years). Give your answers to three decimal places. What's the chance the circuit is still working after one year?   The circuit ended up working for the first year. What's the chance it will last another two years?   What's the expected...
