Modeling the process of choosing energy-saving technologies in the exploitation of transport infrastructure buildings

Abstract

According to the approved strategy for the development of the country's transport complex, the current trend is to increase the energy efficiency of service and industrial buildings. The analysis of scientific research carried out confirms that the variety of energy-saving technologies complicates the process of choosing optimal design solutions. It is also noted that the primary indicators of the choice of energy-saving technologies do not take into account prospective operating costs, as well as a likely decrease in the reliability of the functioning of buildings and structures of the transport infrastructure during operation. Therefore, the purpose of the study was to develop a model for multi-criteria decision making on the choice of the optimal energy-saving technology. The article proposes four levels of ranging of criteria, taking into account federal requirements, regional and industry specifics, as well as the availability of local mechanisms for the implementation of energy-saving technologies. Normalized indicators are referred to supra-rank criteria. The significance of organizational-technological, technical-economic and operational-technical criteria is determined by the expert method. An example of determining the vector of priorities, both criteria for comparison, and alternative energy-saving technologies by the analysis of hierarchies is given. The result of the study is a decision-making model for choosing the optimal energy-saving technology, taking into account the prospects for the operation of transport infrastructure buildings. The practical application of the results obtained is possible both in new construction and in the repair and reconstruction of buildings as an addition to the quality control system of design solutions.

“…The final conceptual model of decision making (Table 1) on the choice of additional protective measure is based on a point estimate of the level of effectiveness of its implementation [22][23][24] and takes into account the degree of reduction of the negative impact of the proposed protective measure, the degree of its influence on the increase in material costs during implementation. The following scale of assessment of the degree of influence of an additional measure on the economic efficiency of works is proposed in the work:…”
