The procedure for determination of the dependence of the cost of insulation materials on their thermophysical characteristics

Abstract

Optimal insulation for the walls of the house is selected based on the material of construction and must meet several requirements. This article describes the method of justifying the dependence of the cost of heaters on their technical characteristics, based on a statistical analysis of price and thermophysical characteristics, used later in the development of optimization models for the selection and use of thermal insulation materials (heaters). To assess the quality of the resulting economic and mathematical model, the coefficient of determination was used. In order for the number of regressors (factors) not to affect the statistics of this coefficient, an adjusted coefficient of determination was also calculated, which gives a "penalty" for the factors included in the model.
