Cet article considère les politiques de remplacement et de maintenance pour une unité opérationnelle qui travaille à des heures aléatoires pour des tâches. L'unité subit des réparations minimes en cas de panne et est remplacée à un moment planifié. T ou à un numéro N des temps de travail, selon la première éventualité. Le taux de coût attendu est obtenu et une politique optimale qui le minimise est dérivée analytiquement. Le modèle de maintenance préventive (PM) imparfaite, dans lequel l'unité est améliorée par PM après la fin de chaque temps de travail, est analysé. De plus, lorsque le travail d'un chantier entraîne des dommages à l'unité, le modèle de remplacement portant le numéro N est proposé. Le taux de coût attendu est obtenu en utilisant la théorie des processus cumulatifs. Deux modèles modifiés, où l'unité est remplacée au numéro N ou à la première réalisation du temps de travail dans le temps T, et il est remplacé à T ou numéro N, selon la dernière éventualité, sont également proposés. Enfin, lorsque l'unité est remplacée au moment T, numéro N or KEn cas de panne, selon la première éventualité, le taux de coût attendu est également obtenu.

Abstract: This paper considers replacement and maintenance policies for an operating unit which works at random times for jobs. The unit undergoes minimal repairs at failures and is replaced at a planned time T or at a number N of working times, whichever occurs first. The expected cost rate is obtained, and an optimal policy which minimizes it is derived analytically. The imperfect preventive maintenance (PM) model, where the unit is improved by PM after the completion of each working time, is analyzed. Furthermore, when the work of a job incurs some damage to the unit, the replacement model with number N is proposed. The expected cost rate is obtained by using theory of cumulative processes. Two modified models, where the unit is replaced at number N or at the first completion of the working time over time T, and it is replaced at T or number N, whichever occurs last, are also proposed. Finally, when the unit is replaced at time T, number N or Kth failure, whichever occurs first, the expected cost rate is also obtained.
