METHOD TO INCREASE EFFICIENCY OF ITEM OPERATION

摘要

FIELD: measurement equipment.;SUBSTANCE: average duration of item control t_c is determined, as well as average duration of item repair t_r, the cost of Y_r of item repair per unit of time, cost Y_c of item control per unit of time, profit ∋_f per unit of time from operation of the item without failures, the average number of failures B(k) of the item per unit of time at the number of controls k, then they make dependence of efficiency of ∋ item operation on the specified parameters of reliability, control and repair. Optimal number of controls k is determined on the basis of the condition d∋/dk=0.;EFFECT: reliability of items with minimum costs.;3 dwg
