description: The work discusses the issues of calculating heat absorption indicators of a floor structure and creating tools for the formation of appropriate design solutions. The tasks solved within the research were the following: 1. Review and analysis of literary sources devoted to the study of the theory of heat resistance and heat absorption and their application in construction, comparative analysis of various designs of pies, floor structures. 2. Development of the optimization model to substantiate the heat absorption characteristics of a floor structure based on the criterion of the unit cost of layer materials. 3. Development of the procedure for substantiating the heat absorption characteristics of a floor structure using global optimization algorithms, implementation of the procedure on practical examples. The study of tools for automated selection of parameters of thermal insulation materials was carried out with the use of normative documentation SP 50.13330.2012 âThermal protection of buildingsâ and SP 131.13330.2020 âConstruction climatologyâ. The results of the analysis of existing works on the theory of heat resistance and heat absorption confirmed the high labor intensity of the process of calculating the heat absorption of floor structures for each alternative combination of layer materials due to the variable (determined by the fulfillment of specific conditions) dependence of the value of the heat absorption index of each previous (relative to the internal environment of the building) layer on a similar value for the subsequent one layer. The results of the analysis of scientific works also testified to the lack of mathematical modeling tools that would reduce the labor intensity of solving the problem of substantiating the characteristics of floor structures, taking into account the requirements stipulated by SP 50.13330.2012 regarding the heat absorption rate of the internal surface of structures. An optimization model has been created, consisting of a minimized objective function, which is the unit cost of materials in the layers of the floor structure, as well as a number of indirect and direct constraints describing the relationships between the thermal characteristics of the mentioned layers. The thicknesses of the floor structure layers were considered as the main unknown variables. The optimization model was implemented using the âSolverâ add-in for the âMicrosoft Excelâ software. Also during the research a procedure has been developed to substantiate the heat absorption characteristics of a floor structure using global optimization algorithms, which includes the following main stages: collection and primary processing of initial data, construction of an optimization model to substantiate the heat absorption characteristics of a floor structure, implementation of the optimization model in the selected optimization modeling software environment , assessment of the practical significance of the results of implementing the optimization model, formation of a constructive solution.
