The subject of this dissertation is reliability systems with multiple failure modes. (two or more failure modes). The failure modes of a system determine when a system is going to «fail», which means that specific combinations of the failure modes of the system turn the system to its non-functional state. In this thesis we present methods for the evaluation of system’s reliability as well as techniques that lead to the determination of the optimal structure of the systems, i.e. the one that provides the maximum system reliability. Also the optimization problem is extended to problems of minimization of system cost or maximization of system profit aiming again at the maximization of system’s reliability. In the present dissertation we also present estimation problems of system’s reliability for some specific classes of structures and investigate optimization problems for these classes.
