The article is devoted to the development of metrological assurance in the field of experience based on solving optimization problems with the involvement of simulation and statistical models. This technique will improve the accuracy of decisions and reduce the time of development of technology. It is important to establish a system of views on the organization of metrological support of field experience on the basis of a system approach, taking into account the relationship and interaction of the various elements and processes of metrological assurance. The article describes an example of measurement processing of a multifactorial field experiment with application of simulation models, produced on the basis of the identification of correlations, tightness and shape which describe the regression equation or the correlation equation, which allows to obtain accurate solutions.

Keywords: field experience, observation, and optimization technologies, simulation model, regression, correlation, correlation coefficient
