More than a half of raw materials for food products are grown by fertilizing plants. The demand of fertilizers has been constantly increasing along the growth of human population. Fertilizer manufacturers face millions of losses each year due to poor quality products. One of the most common reasons is wrong decisions in control of manufacturing processes. Operator\u2019s experience has the highest influence on this. This paper analyzes the pellet measurement data, collected at the fertilizer plant by using indirect measurements. The results of these measurements are used to construct the model of equipment status control, based on the fuzzy logic. The proposed solution allows to respond to changes in production parameters in a 7\u201310 times faster manner. On average, a manufacturer with production volumes of up to 80 tonnes\/hour could have lost about 8400 tonnes\/year of high-quality production. The publication seeks symmetry between human and system decision making.<\/jats:p>","DOI":"10.3390\/sym11111396","type":"journal-article","created":{"date-parts":[[2019,11,13]],"date-time":"2019-11-13T09:11:27Z","timestamp":1573636287000},"page":"1396","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Research of the Operator\u2019s Advisory System Based on Fuzzy Logic for Pelletizing Equipment"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9862-8917","authenticated-orcid":false,"given":"Darius","family":"Andriukaitis","sequence":"first","affiliation":[{"name":"Department of Electronics Engineering, Kaunas University of Technology, Studentu St.50-438, LT-51368 Kaunas, Lithuania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andrius","family":"Laucka","sequence":"additional","affiliation":[{"name":"Department of Electronics Engineering, Kaunas University of Technology, Studentu St.50-438, LT-51368 Kaunas, Lithuania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Algimantas","family":"Valinevicius","sequence":"additional","affiliation":[{"name":"Department of Electronics Engineering, Kaunas University of Technology, Studentu St.50-438, LT-51368 Kaunas, Lithuania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mindaugas","family":"Zilys","sequence":"additional","affiliation":[{"name":"Department of Electronics Engineering, Kaunas University of Technology, Studentu St.50-438, LT-51368 Kaunas, Lithuania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vytautas","family":"Markevicius","sequence":"additional","affiliation":[{"name":"Department of Electronics Engineering, Kaunas University of Technology, Studentu St.50-438, LT-51368 Kaunas, Lithuania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dangirutis","family":"Navikas","sequence":"additional","affiliation":[{"name":"Department of Electronics Engineering, Kaunas University of Technology, Studentu St.50-438, LT-51368 Kaunas, Lithuania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2430-1815","authenticated-orcid":false,"given":"Roman","family":"Sotner","sequence":"additional","affiliation":[{"name":"Department of Radio Electronics, SIX Research Center, Brno University of Technology, Technicka 3082\/12, 616 00 Brno, Czech Republic"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5286-9574","authenticated-orcid":false,"given":"Jiri","family":"Petrzela","sequence":"additional","affiliation":[{"name":"Department of Radio Electronics, SIX Research Center, Brno University of Technology, Technicka 3082\/12, 616 00 Brno, Czech Republic"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9487-5024","authenticated-orcid":false,"given":"Jan","family":"Jerabek","sequence":"additional","affiliation":[{"name":"Department of Telecommunications, SIX Research Center, Brno University of Technology, Technicka 3082\/12, 616 00 Brno, Czech Republic"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9504-2275","authenticated-orcid":false,"given":"Norbert","family":"Herencsar","sequence":"additional","affiliation":[{"name":"Department of Telecommunications, SIX Research Center, Brno University of Technology, Technicka 3082\/12, 616 00 Brno, Czech Republic"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0019-8371","authenticated-orcid":false,"given":"Dardan","family":"Klimenta","sequence":"additional","affiliation":[{"name":"Faculty of Technical Sciences Kosovska Mitrovica, University of Pristina in Kosovska Mitrovica, Kneza Milosa St. 7, RS-38220 Kosovska Mitrovica, Serbia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2019,11,12]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"174","DOI":"10.1016\/j.proeng.2015.01.122","article-title":"Urea Finishing Process: Prilling Versus Granulation","volume":"102","author":"Rahmanian","year":"2015","journal-title":"Procedia Eng."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"571","DOI":"10.5958\/0974-360X.2016.00108.6","article-title":"Advances in Granulation Technology","volume":"9","author":"Sahoo","year":"2016","journal-title":"Res.
