Approaches to reducing the dimension of multicomponent of structurally complex multi-state systems in the assessment of reliability

In the paper the description of approaches to reduce the dimension of structurally complex systems on assessing their reliability is given. The use of probability-algebraic simulation for the parts of the system with a parallel-series connection of components is proposed. Calculation of reliability of structurally complex systems with many states is achieved by using methods of information system models with multi-state settlement to the binary model.
