Multiple criteria analysis when choosing the technology of the sound insulation device of the monolithic interflooring

Formulation of the problem. This work is devoted to the solution of an important problem of choosing rational technological solutions for the sound insulation device of interflooring in frame-monolithic house building by conducting multiple criteria analysis. For this purpose, we used the results of a comparative analysis of organizational and technological indicators for the sound insulations of floors using various materials and their design features. Goals and targets. The purpose of this work is the selection and justification of structural and technological solutions for sound insulation of floors in frame-monolithic housing construction. For achieving this goal, the following tasks are defined: to investigate the influence of the floor constructive on the sound-insulation values; to conduct a multiple criteria analysis, on the basis of which to choose a rational technological solution for the sound insulation device of interflooring in frame-monolithic housing construction. For achieving this, it is necessary to choose materials and constructive-technological schemes for their device, as well as to conduct a comparative evaluation. Conclusion. Multiple criteria analysis of the sound insulation technology of floors allowed to determine the most rational option, according to a single rating scale. The results of the studies on the basis of the multiple criteria analysis methodology allowed us to determine the rational and effective structural and technological solution of the multilayer overlap system based on the Isolon 500 material of the first type.
