Your company produces a system which consists of a memory and a processor. To increase the systems reliability, the memory is duplicated and the processor is triplicated. The reliabilities of the memory and the processor for the first year of operation are RM(1year) = 0.95 and RP(1year) = 0.9, and their costs are $50 and $30 respectively. You boss decides that the system is too expensive. She would like you to reduce its cost by using processors with a higher reliability. There are three manufacturers producing processors which are suitable for your system. They offer processors with the following reliabilities and costs: 1. RP1 (1year) = 0.9683 for $40 2. RP2 (1year) = 0.9812 for $45 3. RP3 (1year) = 0.9989 for $50 Your task is to estimate which processor minimizes the cost of the system without decreasing its reliability compared to the original system. You are allowed to combine processors from different manufacturers. You can also change how much redundancy you want to include, for example fewer memory modules fewer processor modules or more memory module and more processor modules. Draw an RBD of the new system.
