Types of maintenance

In maintenance operations the following definitions can be distinguished:[2][3]​.

The main types of industrial maintenance are classified as corrective, preventive and predictive. This classification is used in international standards such as ISO 17359, which establishes guidelines for the monitoring and diagnosis of machines.[4]​.

This is especially relevant in industries such as aerospace, military installations, large industrial complexes or shipping companies. One of the functions of this software is the configuration of a set of materials, making lists of the parts corresponding to engineering and manufacturing and updating them from “delivered” to “maintained” and finally to “used”. Another function is the planning of logistics projects, such as identifying the critical elements of a list that must be carried out (inspection, diagnosis, location of parts and service) and the calculation of response times.
