Abstract
In this article we have focused on optimizing the service policy for stochastically deteriorating system with long latent (incubational) stage of defect development (e.g., a surface fatigue). We consider the preventive replacement threshold as a decision variable for an agricultural machine unit, which inspection is carried out before the process operation. Optimization of a preventive replacement threshold is performed on the criterion of minimum total production costs, which consist of losses of the part of the harvest due to a failure and maintenance costs.
