Application of the Simple Additive Weighting Method in the Assessment Process of Air Pollution on the Campus of the Silesian University of Technology

The article presents the measurement results of the concentration of dust PM₁₀ and PM_2.5 as well as SO₂, NO, NO₂ and NO_x based on a mobile laboratory located on the campus of the Silesian University of Technology (Poland, Gliwice, Konarskiego 20B, 50.292934N, 18.682164E), in the so-called “winter period” in 2020 (from 01/01/2020 to 31/03/2020 and from 01/10/2020 to 31/12/2020). The obtained results were used to carry out a synthetic (aggregated) assessment of the threat to the anthropogenic environment, the so-called “objects”, i.e. days on which the measurements were made, interpreted as points in the multidimensional space with coordinates corresponding to the measurement results of the concentration of dust pollutants: PM₁₀ and PM_2.5 and gaseous pollutants: SO₂, NO, NO₂ and NO_x. The determined synthetic values additionally allowed for ordering (creating rankings) of the examined “objects” in terms of air quality. For the calculations, the Simple Additive Weighting method (SAW) was used, which belongs to the group of single-criteria synthesis methods.
