The application of the even-swap-based scoring system to the selection of the heating source in house building projects

In this paper, we present the mechanism of scoring alternatives based on the even-swap method. The mechanism we propose derives from the notion of additive scoring systems that are commonly used in multiple criteria decision-making. In contrast to the classic approach, we use the notion of aggregated equivalent amounts defined in the even-swap procedure. This allows to determine the global scores of alternatives that can be easily interpreted and compared by a decision-maker, since they are natural and intuitive, e.g., price. We modify the original even-swap algorithm, which enables us to construct a scoring system and to find the ranking of all alternatives by means of single non-artificial criterion. In this paper, we apply the algorithm of the modified approach to the problem of selecting the heating source for an individual house building project.
