MagTech assembles tape players from four major compo-nents arranged as follows:The components can be purchased from three differentvendors, who have supplied the following reliability data:a. If MagTech has decided to use only one vendor tosupply all four components, which vendor should beselected?b. Would your decision change if all the components wereassembled in series?
Determine the reliability of the complex system shown if the failure rate of each component is 0.02.
Even after taking all appropriate steps to produce a high integrity system, some remaining faults will remain. How would you ensure system safety and reliability in practical approaches?
