Research methods - probability theory methods, computer modeling, synergetic control theory, engineering diagnostics, fracture mechanics, reliability and expert system theories. The results obtained - comparative analysis of estimation, prognostication and control of complicated engineering systems resource methods is made. Problem state-of-art and improvement guidelines for control methods of complicated engineering systems resource are considered. Main tasks of development of probabilistic-statistical methods for complicated engineering systems resource control are formulated. The upper found of average resource on the basis of minimal way and section method is made and Weibull's distribution of elements time to failure is described. Correlations between system residual resource and system elements residual resources are made. Asymptotical values of residual resource for some reliability distributions are obtained. Methodological bases of control of complicated engineering systems average and residual resource are made. The application fields - design of complicated engineering systems in mechanical engineering, rocket production and oil-processing industry.
