2. A system has four identical modules and they are connected in parallel (RBD). The system is functional as long as one module is functional. Each module has the same failure rate a. a)Draw the state transition diagram for this system. (Hint: try to simplify - Look for a simplified state transition diagram.) b)Derive the transition matrix M for the system. c)Write the system of state transition equations: You do not have to solve it. d P(t) = M.P(t) dT 2.
