| Popis: | This paper describes a numerical procedure as well as a computer program for predicting the changes of cement compressive strength caused by varying raw components in an initial mixture. It was achieved by statistical processing of the measured values. As a result the coefficients for correlating function of beforehand chosen type were determined. So aquired correlation was adopted as an objective function of the optimization problem, which mathematical model was completed after taking into account certain process-, market- and empirical constraints. By solving the model two combinations of raw components (for two different requirements) were defined. |
