- Abstract
The goal of this work is determining the periodicity T0 which the preventive maintenance will execute for minimizing the operation cost. This type of preventive change is very used in practice by industrial manufacturing. In this study, we choose the model of block replacement type1: A failed unit is replaced instantaneously at failure. The mathematical model used is based on the Weibull law with γ = 0. The results obtained are discussed according to the values of the parameters of the Weibull law β, η and of the cost of preventive maintenance Cp and cost failure Cf, for which the minimal cost Cm has been determined in each case.
