The increasing complexity and cost of production equipment have led to a significant rise in their 
usage intensity, highlighting the need for effective maintenance to ensure optimal performance of 
installations and machinery. Maintaining production equipment is a key issue for factory productivity 
as well as for product quality. This industrial challenge requires a reassessment of current rigid 
structures and the promotion of methods adapted to the evolving nature of equipment. 
Any sector of activity that needs to maintain a continuous level of production or service activity. 
Today, companies can no longer neglect the upkeep of their production equipment. They are becoming 
aware of the economic stakes and are including maintenance in their investment decisions. 
Maintenance is considered a source of optimization for production equipment and even a driver of 
profit. 
The maintenance of industrial systems has become an essential point during their design and 
operation, both for reasons of safety and operational reliability, and for reasons of profitability. 
Inadequate maintenance for a system can lead to critical situations, posing dangers to people, 
equipment, and the environment. 
Maintenance isn't always about being able to restart faulty equipment; it's about mastering that 
equipment to the point of creating a maintenance schedule. This function should be a means of 
optimizing downtime and reducing production losses. 
The purpose of this handout is to provide students with a means to strengthen their knowledge of 
Maintenance. Through this material, students will gain knowledge of the role of maintenance in the 
company; its organization, as well as its various objectives; they will also be able to perform 
calculations related to reliability.
