چکیده
Aplikácia simulačných modelov pre optimalizáciu zložení uholných zmesí V prostrediu trhovej ekonomiky sú kladené zvlášť vysoké požiadavky na riadenie výrobných technológií v oblasti uholných hlbinných baní (ťažba, odťaženie, apod.) z hľadiska dosiahnutia čo najlepších ekonomických parametrov ( produktivita práce, zisk, rentabilita). Jednou z možností ich zlepšení je aj užitie metód selektívnej ťažby a homogenizácie. Toto je však veľmi zložitý technický problém a jeho riadenie patrí k problémom, ktoré doposiaľ neboli uspokojivo vyriešené. Metódy riadenia týchto procesov sú založené na modelovom riešení štandartných i neštandartných situácií a na využitiu simulačného systému. Článok je zameraný na možnosti využívania simulačných modelov aplikovateľných na problematiku riadenia selektívnej ťažby a homogenizácie. Na podklade výsledkov riešenia projektov GAČR: 105/ 94/1119 a 105/97/1320, sme na našom pracovisku ( Inštitútu ekonomiky a systémov riadenia, na HGF, VŠB – TU Ostrava ) vyvinuli simulačný program, ktorý sme nazvali SIMDUL. Tento program umožňuje vytvorenie simulačného počítačového modelu konkrétnej hlbinnej bani, bez potreby programovania, formou interakčného dialógu užívatelia so systémom s možnosťou simulovať dynamicky kontinuálne vývoj kvalitatívnych parametrov uholných zmesí v zásobníkoch a na linkách pásových dopravníkov v bani s možnosťou optimalizácie ich zložení.
