Book Chapter Description

The structure of decision support tools for determining the priority of energy-saving projects has been developed. It is determined that for the effective operation of the decision support system in determining the priority of energy-saving projects, the system should include: means of collecting and storing information about the energy efficiency of the enterprise; means of numerical evaluation of selection criteria; simulation model for determining the priority of energy-saving projects; means of forecasting energy efficiency of the enterprise taking into account the implementation of the energy-saving project; means of visualization of simulation results. The method of pairwise comparison is proposed and the scale for estimating the weights of the importance of selection criteria is modified. A model for determining the priority of energy-saving projects has been developed, which is based on the method of hierarchy analysis and takes into account the interaction and interdependence of project selection criteria. A list of economic, technical, production, environmental and organizational criteria for the selection of energy-saving investment projects has been formed. It is shown that the development of the model for determining the priority of investment energy-saving projects is performed in five stages: at the first stage—the task of determining the priority of investment energy-saving projects in the form of the three-level tree of hierarchies; at the second stage—expert numerical evaluation of economic, technical, production, environmental and organizational selection criteria is carried out; at the third stage—a matrix of pairwise comparisons is formed and the eigenvector and the vector of priorities for the second level of the hierarchy are calculated; At the fourth stage we form a matrix of pairwise comparisons and calculate the vector of priorities for each energy-saving project; in the fifth stage—the vector of global priorities is calculated. A block diagram of the operation algorithm has been developed and a simulation model for determining the priority of investment energy-saving projects has been implemented using MATLAB. Approbation of the simulation model on the basis of the municipal enterprise “Sambir Vodokanal” was carried out.
