Optimizing the Indicators of the Shovel-Truck System Operation at Open-Pit Coal Mines by Quality Criterion

Abstract: Одной из основных проблем экскаваторно-автомобильных комплексов (ЭАК) разрезов является достаточно низкий уровень качества их работы. Мощным средством повышения качества функционирования ЭАК является его оптимизация, осуществляемая по логико-математической модели, включающей целевую функцию и ограничения, накладываемые спецификой работы ЭАК и внешней горной средой. В качестве целевого критерия выбран обобщенный показатель качества функционирования ЭАК; в качестве оптимизируемых параметров-основные показатели к… Show more

“…But the value of 𝑘 𝑁 * for the summer period (6,653) can be reduced. A decrease in the value of 𝑘 𝑁 * from 6,653 to 6,60 means that, in accordance with the margin for the limitation of the STS efficiency [11], its decrease will not be 1,529 (maximum), but 1,474. In proportion to this coefficient, the values of 𝑡 𝑙 𝑠 and 𝑡 ℎ will also change.…”
