This paper presents an algorithm based on fuzzy logic that models a Maintenance Management Plan of Medical Equipment, this is developed in three stages: In the first one, a functional inventory is generated, following the protocols recommended by the WHO and information of each team. In the second, three priority attention protocols are attached, used to select the diffuse system membership functions. In the third, a family of scenarios is generated by Monte Carlo simulation, calculating the degreeof fuzzy maintenance priority for the equipment. The results achieve that the equipment selection of the annual maintenance plan is carried out guaranteeing the availability of the priority equipment. In this article, the application of the Fennigkoh-Smith algorithms and the Wang-Levenson algorithm are improved by placing the ambiguity of the diffuse structure, making the selection of the medical equipment incorporate the range of possibilities that exist when selected in an arbitrary manner. An area of opportunity consists of incorporating a process of optimization of equipment maintenance costs with a budgetary restriction. It is concluded that the system shown is friendly and robust for the purposes proposed.
