Abstract. A method is proposed for improvement of approximated bound for complex system reliability. The method is based on combination of the Esary — Proschan and Litvak — Ushakov upper and lower approximations.
Keywords: boundary approximation, reliability, minimal pass, minimal cross-section, Esary — Proschan approximation, Litvak — Ushakov approximation
