Deterministic Strategies and Life-time

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 eláre.
