The spectral portraits method in digital threpsology
Abstract:
The paper analyzes a mathematical model for calculating the composition and size of portions of the optimal menu in accordance with the recommendations of the Ministry of Health, depending on the planning horizon. The questions of the accuracy of the solution depending on the accuracy of the input data are considered. Spectral portraits of diurnal and averaged nutrient matrices are studied. It is shown, that despite the poor conditionality of the daily matrices, the result of weekly averaging allows us to perform calculations at a sufficient level of accuracy.
