Abstract : As some circuit elements (resistors, capacitors, diodes) may have three states - operable, short-circuit, and break - a ternary logic is well suited to describe their reliability. Reliability probabilistic formulas in ternary notations are written. Five examples of series-paralle circuits illustrate the use of the formulas. It is found that: the reliability of a system, in which every element is provided with a reserve element, can be calculated by means of a binary logic if short-circuits and breaks are taken into account separately; the ternary system permits calculating the reliability of the structure as a whole; the binary logic is inapplicable to some systems; the ternary logic can be used in such cases; the use of the ternary logic opens the possibility for using an s-nary logic in systems whose elements can exist in one of s states.
