Purpose: of the work concerns the theoretical generalization and solving of the scientific problem of increasing the efficiency processes of technical system planning and producing, providing of the necessary level of quality by the automated control based on the mathematical design and complex optimization. Design/methodology/approach: used the methods of probability theory and mathematical statistics, theories of matrices, theory of prognostication, analysis and control of security, methods of design and optimization of production processes, as well as methods of analysis of systems and theory of systems. Findings: The developed variant of through modeling of matrix stream formation and transformation processes with the use of universal probability quality criterion meets requirements as a new approach for the development of optimization models and programs. The variant has no significant structural and parameter limits. Experimental-statistical research of the suggested modeling methods proved their efficiency. Practical implications: The gained results form the theoretical engineering methodology basis of enhancement the technico-economical parameters of technical systems using automated control, modeling and complex optimization of designed processes, production and operation due to the criteria of quality and total production. Originality/value: Original models and methods of sophisticated technical system security by the way of complex multi-critirion production process optimization are suggested. The scientific base is the developed theory of production defect stream formation at all stages and their through estimation with the help of universal criteria.
