在这篇文章中，我们开发了一个模型，以帮助维护决策的情况下，一个给定的设备。我们提出了一个新的模型，以确定最佳的生命周期持续时间和大修之间的间隔，最大限度地减少全球维护成本。我们考虑这样一种情况，即拥有设备的客户可以通过为设备提供改进的预防性维护计划来谈判更好的保修合同。设备接受三种操作：修理、大修和更换。大修代表一种不完美的维护行为，即故障率得到改善，但不是设备完好如新的一点。在每次维修后的故障率与故障前相同的意义上，纠正性维护措施是最小的。所提出的策略优于其他文献中看到的，因为它认为在同一时间的保修谈判的情况下，不完善的预防措施和最佳的生命周期持续时间。我们还提出了一个简化的方法，便于在标准求解器中实现该方法的任务。
In this article, we develop a model to help a maintenance decision making situation of a given equipment. We propose a novel model to determine optimal life-cycle duration and intervals between overhauls by minimizing global maintenance costs. We consider a situation where the costumer, which owns the equipment, may negotiate a better warranty contract by offering an improved preventive maintenance program for the equipment. The equipment receives three kind of actions: repairs, overhauls, and replacement. An overhaul represents an imperfect maintenance action, that is, the failure rate is improved but not a point that the equipment is as good as new. Corrective maintenance actions are minimal, in the sense that the failure rate after each repair is the same as before the failure. The proposed strategy surpasses others seen in the literature since it considers at the same time the warranty negotiation situation and the optimal life-cycle duration under imperfect preventive actions. We also propose a simplified approach that facilitates the task of implementing the method in standard solvers.
