The project aims to develop theoretical foundations of calculating the reliability of fault-tolerant multiprocessor systems that control complex objects. The method is based on the performing of statistical experiments with special mathematical models of the behavior of fault-tolerant multiprocessor systems in a flow of failures that have been developed for the first time and named graph-logic. A new method for synthesis the graph-logic models that adequately reflects the system's reaction to the appearance of faults of its components depending on the given parameters and system specifications are proposed. The main model parameters affecting the accuracy of the calculation of reliability are defined. The methods minimizing models and their optimization criteria are offered. The methodology of calculating the reliability, an algorithm for performing statistical experiments and calculation the error are proposed. The hardware is developed that used in the calculation of reliability, in particular the schemes of controllable random number generators with constant weight, which simulate the flow of failures of system components. These methods and tools makes the calculation methodology of reliability suitable for any system and improves its accuracy.
