The formed database on the consumption of concrete in the construction of bridges, along with their project characteristics, was the basis for the formation of the assessment model. The models were built using information from 181 reinforced concrete bridges in the eastern and southern branches of Corridor X in Serbia, with a value of more than 100 million euros. The application of artificial neural network models (ANNs), models based on regression trees (RTs), models based on support vector machines (SVM), and Gaussian processes regression (GPR) were analyzed. The accuracy of each model is determined by multi-criterion evaluation against four accuracy criteria root mean square error (RMSE), mean absolute error (MAE), Pearson\u2019s linear correlation coefficient (R), and mean absolute percentage error (MAPE). According to all established criteria, the model based on GPR demonstrated the greatest accuracy in calculating the concrete consumption of bridges. According to the study, using automatic relevance determination (ARD) covariance functions results in the most accurate and optimal models and also makes it possible to see how important each input variable is to the model\u2019s accuracy.<\/jats:p>","DOI":"10.3390\/axioms12010019","type":"journal-article","created":{"date-parts":[[2022,12,27]],"date-time":"2022-12-27T02:55:07Z","timestamp":1672109707000},"page":"19","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Decision-Support System for Estimating Resource Consumption in Bridge Construction Based on Machine Learning"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0740-2136","authenticated-orcid":false,"given":"Miljan","family":"Kova\u010devi\u0107","sequence":"first","affiliation":[{"name":"Faculty of Technical Sciences, University of Pristina, Knjaza Milosa 7, 38220 Kosovska Mitrovica, Serbia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nenad","family":"Ivani\u0161evi\u0107","sequence":"additional","affiliation":[{"name":"Faculty of Civil Engineering, University of Belgrade, Bulevar kralja Aleksandra 73, 11000 Belgrade, Serbia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dragan","family":"Stevi\u0107","sequence":"additional","affiliation":[{"name":"Faculty of Technical Sciences, University of Pristina, Knjaza Milosa 7, 38220 Kosovska Mitrovica, Serbia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ljiljana Mili\u0107","family":"Markovi\u0107","sequence":"additional","affiliation":[{"name":"Department of Transportation Engineering and Geotechnics, Faculty of Architecture, Civil Engineering and Geodesy, University of Banja Luka, 78000 Banja Luka, The Republic of Srpska, Bosnia and Herzegovina"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9241-1469","authenticated-orcid":false,"given":"Borko","family":"Bulaji\u0107","sequence":"additional","affiliation":[{"name":"Faculty of Technical Sciences, University of Novi Sad, Trg Dositeja Obradovi\u0107a 6, 21000 Novi Sad, Serbia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ljubo","family":"Markovi\u0107","sequence":"additional","affiliation":[{"name":"Faculty of Technical Sciences, University of Pristina, Knjaza Milosa 7, 38220 Kosovska Mitrovica, Serbia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0506-2887","authenticated-orcid":false,"given":"Nikola","family":"Gvozdovi\u0107","sequence":"additional","affiliation":[{"name":"Master of Science, Univers d.o.o., 38220 Kosovska Mitrovica, Serbia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,12,24]]},"reference":[{"key":"ref_1","unstructured":"Pr\u017eulj, M.
