Lindavista CO 07738 Mexico city, MexicoThe aim of the present paper is to approach the matter of water quality by resorting to the metod of multicriterial mathematical programming. MicrosoftExcel enables the simulation of a mathematical model. Furthermore, we have also created a file in the C++ software, in view of the simulation process, applicable to numberless properties of water quality. The case study presents the simulation of a multicriterial analysis of water quality in Sibiu county. This particular study shows the means of obtaining more information about water quality, subsequent to the analysis of its characteristics resorting to statistical analysis-specific software, e.g. SPSS 16 software. Given the increase of drinking water worldwide by tens of percentage points in cca two decades, the author(s) consider(s) that an approach to the quality management of drinking water should represent a key priority of society.111520211115202117242https://www.naun.org/main/NAUN/geology/2021/a042004-002(2021).pdf10.46300/9105.2021.15.2https://www.naun.org/main/NAUN/geology/2021/a042004-002(2021).pdf10.1111/j.1752-1688.2001.tb05480.xCude, C.G., „Oregon Water Quality Index A Tool For Evaluating Water Quality Management Effectiveness”, Journal of the American Water Resources Association, 37, 1,2001, pp. 125-137.
