Question: A complex engineering system can be modelled by a reliability block diagram, where individual component reliabilities play an important role in the overall system's performance.
A complex engineering system can be modelled by a reliability block diagram, where individual component reliabilities play an important role in the overall system's performance. Individual components may be deployed in different applying schemes, in series, in parallel or m out of n configurations. FIGURE Q2 shows three baskets A, B & C having different system components in them. Reliabilities of various components in each basket are shown on top of the baskets. 85% 75% 90% Basket-A Basket-C Basket-B FIGURE Q2 Design a complex system using at least half number of components from each basket. You must have to use all the components application configurations, i.e., in series, in parallel and m out of n. Use at least, m=2 and n=4. Estimate the overall reliability of your proposed system. Identify the weakest reliability point in your system and suggest the way to improve the overall reliability of your system. If the reliability of the components in Basket-A, is deteriorating with the usage and passage of time @5% per annum, estimate the reliability of the system at the end of second year.
