Abstract:
The goal of this work is determining the periodicity 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 replacement model based on age: the age of each part is known and
the part is changed as soon as its age reaches the T0 value. The mathematical model used is based on the Weibull
law with Gamma =0. The results obtained are discussed according to the values of the parameters of the Weibull
law Beta and Eta and of the cost of preventive maintenance and the cost failure, for which the minimal cost has
been determined in each case
