The object of study: the process of formation and technical articles (and) technology of their production with a given level of quality, subject of study - formalized the task of designing, constructing, monitoring, diagnosis, prognosis, strength. The goal - setting and the development of problem-solving techniques to ensure a given level of performance quality of products through the optimal choice of design and process-based nominal values and tolerances for primary design factors. Theoretical studies were carried out by mathematical and physical modeling of devices and processes using the methods of applied mathematics in solving problems of minimization of linear algebra, matrix theory, estimation and identification methods of optimal and adaptive control. Checking the efficiency and effectiveness of the algorithm using a computer simulation using modern means of automation of mathematical calculations, vibration and strain gauge instrumentation. The paper formulated, formalized task of ensuring the performance of complex systems, developed a general method of statistical processing of empirical data polymodal distribution law that allowed us to obtain more accurate values with a certain reliability, developed a method of test parameters to refine mathematical models taking into account the degree of idealization of real objects and their conditions. Designed calculation-experimental method of identifying the physical and mechanical properties of materials, found their allowable values and tolerances on the geometric dimensions of the structural elements of the electronic assembly, which is guaranteed in the conditions specified temperature difference. The developed method of construction of hybrid multistage statistically deterministic models of complex systems has allowed 12.8 times reduce the amount of necessary experimental research in modeling capacity aircraft defendant to ensure its operability. The results are used in the educational process in teaching disciplines "Mathematical methods of optimization and decision making" and "Mathematical modeling of systems and processes."
