Radchenko S. Stochastic models of quality parameters of technological systems

Об'єкт дослідження - Information technologies on a basis multifactoral of stochastic mathematical models of linear rather independent parameters. Мета дослідження - Development of units of the theory of obtaining stochastic multifactoral of mathematical models for multicreterial of simulation of structural and parametric links of conditions of operation and criterions of quality of real technological systems and processes. Методи дослідження і апаратура - Technical cybernetics, theory of probabilities, application statistics, theory of design of experiment, theory of approximating of functions, topology. The equipment - Exemplary dinamometr of compression, indicator of a hour type, large tool microscope, PC and software PRIAM. Теоретичні результати і новизна - The units of the theory of creation stochastic multifactoral of mathematical models for multicreterial of simulation of structural and parametric links of conditions of operation and criterions of quality of real technological systems and process es are developed. The methodology of designing stable (robust) fractional factoral experiment has received further development. Effective algorithm of the formalized definition of structure linear concerning parameters of the equation of multiple regression for the first time is created. Algorithms of a stable estimation of coefficients multifactoral of the equation of regression in conditions of mutual contingency (multicollinearity) of the factors for the first time are offered. Практичні результати і новизна - The methods multifactoral mathematical simulation of technological systems and processes are developed. The modes of processing heat resisting nickel alloys ЭП 741 НП and ЭП 539 ЛМ are optimized. The modes of the technological process of honing shells of cylinders of the engine of internal combustion are optimized. Developed the methodology multifactoral mathematical simulation and software PRIAM were used for preparation of more than 20 dissertations and used for reading of the lectures on courses " Bases of scientific researches both technical creativity", "Mathematical simulation and optimization of technological systems" and other. Предмет і ступінь впровадження - Formalized obtaining multifactoral stochastic mathematical models of real technological systems with the purpose of the information description and perfecting of these systems. 20 completed R&D works, and also into the educational process are actually introduced for want of execution. Ефективність впровадження - The total economic prophit confirmed by appropriate documents has made 4 mln and 842 thous. Rbl. (in the prices till July 1, 1989). Сфери використання - Development new and improvement of existing technological systems and processes, knowledge-intensive products, tools of measurements and measuring systems and other.
