When designing power facilities, the problem usually arises of comparing their possible options for performance, taking into account consumer quality. A common and easy-to-implement method is the formation of a generalized indicator, however, subjectivity is inherent in it, given this, the task of developing algorithms and methods that objectively consider the quality indicators of an energy object becomes especially urgent.
It is argued that, in accordance with the condition for making a decision on the type of the synthesizing function, the main object of uncertainty, respectively, of the quality indicator, which is inherently subjective, is the vector of the significance coefficients of the weight coefficients.
The presented algorithms in conditions of uncertainty that allow you to build a generalized quality criterion for energy facilities. For a comprehensive assessment of the quality of energy facilities, it is proposed to use the methods of arbitrary summary indicators, namely: the method of arbitrary summary indicators, the method of priority of private quality indicators and the method of minimizing the deviation of the summary quality indicator. It is proposed to reduce the influence of subjective factors in determining the weight coefficients, it is advisable to use a combination of these methods. For the method of minimizing the deviation of the aggregate indicator, using the principle of objectivity, an algorithm for determining the weight coefficients has been developed, taking into account that in the area of permissible changes in parameters, the value of the criterion will be minimal.
Accordingly, to solve the problem of comparing the options for constructing energy facilities, which includes the determination of weight coefficients for the formation of a composite indicator, it is necessary to use the results of expert assessment that are supplemented by calculation methods that will reduce the subjective factor that is inherent in the method of expert assessment.
Key words: quality indicator, methods of determining weighting factors, summary quality indicator
