The selection of the most appropriate underground mining technology is not a simple process because it involves handling of a large amount of information about several potential methods. Multicriteria optimization approaches are proven useful tools for ranking alternatives, especially in cases where multiple complex criteria have to be considered simultaneously. An ore deposit is a complex system because of its geology, physical and mechanical properties, and hydrogeological conditions. As such, problem solving requires a heuristic approach and includes tasks involving expert judgement, intuition, estimation, and experience. Using a heuristic strategy to state a problem means that the analyst is placed in a position to apply past experience to a future situation and existing knowledge to new circumstances, as well as discover new avenues to creative problem solving. A complex algorithm was developed to pave the way to quality management of mining, by using the VIKOR method to rank various mining technologies relative to a set of criteria and select the optimum mining method that will primarily ensure profitable and safe mining.

After the migration of Serbs in 1690 and 1735, the exploitation of mines in the area of present-day Serbia ceased, and after a standstill of nearly 200 years, the mining and metallurgical activities in Serbia were activated in the second quarter of the 20th century. The first concessions were bought by England in 1926, then the mines in Stari Trg (1927), Kišnica (1927), Ajvalija (1930), Novo Brdo (1933) were activated, and the Flotation (1930) and Smelter with Lead Refinery began to operate (1939) in Zvečan. In Kosovska Mitrovica, the chemical industry began operating in 1961, the Zinc Metallurgy and Lead Battery Factory in 1967, and all production facilities were expanded and modernized several times. The most intensive production and investment period of the "Trepča" Combine was in the period 1965-1985, when "Trepča" was a well-known producer of lead, zinc, silver, gold, cadmium, bismuth and products made of these metals. After 1990, the production declined for several reasons and, in 1999, the international army stopped production in "Trepča". In the past twenty years, the production has not been completely renewed nor the status of the "Trepča" Combine has not been regulated.

2 30 11 47 M50 М52 Posle seobe Srba 1690. i 1735. godine, dolazi do prestanka eksploatacije rudnika na prostoru sadašnje Srbije i nakon zastoja od blizu 200 godina, aktivirana je rudarsko-metalurška delatnost u Srbiji u drugom kvartalu 20. veka. Prve koncesije otkupili su Englezi 1926. godine, zatim se aktiviraju rudnici u Starom Trgu (1927.), Kišnici (1927.), Ajvaliji (1930.), Novom Brdu (1933.), a u Zvečanu počinje da radi Flotacija (1930.) i Topionica sa Rafinerijom olova (1939.). U Kosovskoj Mitrovici počinje sa radom hemijska industruja 1961. godine, Metalurgija cinka i Fabrika olovnih akumulatora 1967. godine, a svi proizvodni pogoni više puta su proširivani i modernizovani. Najintenzivniji proizvodno-investicioni period Kombinata „Trepča“ bio je od 1965-1985. godine kada je „Trepča“ bila poznati proizvođač olova, cinka, srebra, zlata, kadmijuma, bizmuta i proizvoda od ovih metala. Posle 1990. godine dolazi do opadanja proizvodnje iz više razloga, a međunarodna vojska 1999. godine obustavila je proizvodnju u „Trepči“. U proteklih dvadeset godina još uvek nije u potpunosti obnovljena proizvodnja niti je regulisan status Kombinata „Trepča“.
