Homework 8 (19 March 2015) 1. Assume that the reliability of component j in the following system is Rj, where j = A, B, …, F. Evaluate the system reliability using 1) Decomposition; 2) System structure function 2. A radio set consists of three major components: a power supply, a receiver, and an amplifier, having reliabilities of 0.8, 0.9, and 0.85, respectively. Compute systems reliabilities for both high-level and low-level redundancy for systems with two parallel components.

Unformatted text preview: 3. A space vehicle requires three out of its four main engines to operate in order to achieve orbit. If each engine has a reliability of 0.97, determine the reliability of achieving orbit. 4. As shown in Figure 1, if ± = ² =0.9, ³ = ´ =0.95, and µ =0.80, what’s the system reliability? Figure 1 A lined network 5. For the network in Figure 1, 1) Find the minimal paths and minimal cuts. 2) Construct a lower bound and an upper bound on the system reliability....

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
