%0 Journal Article %T Deterministic Strategies and Life-time %A Anna Pavliskov¨˘ %J Acta Montanistica Slovaca %D 2007 %I Technical University of Kosice %X The work deals with practical application of the deterministic strategy. It describes three models based on optimal life-time. The article introduces equations allowing to calculate life-time for the three models. These are compared with regard to their practical use and to operational life-time of conveyor belts. The linear regression is used for the comparison. Estimation of cost function constants and setting optimal life-time are applied to conveyor belts sample from the quarry V el¨˘re. %K deterministic strategies %K cost function %K optimal life-time %K optimal live-time strategy %U http://actamont.tuke.sk/pdf/2007/n3/15pavliskova.pdf
