ABSTRACT
The essential problem for a maintenance service is the optimization of its maintenance plan and the costs involved for the accidental failures. They may have serious consequences on the technical, economic and organizational parameters. The industrial maintenance, which aims to ensure the good functioning of the production tools, is a strategic function in a company. This is bound to the apparition of the new kind of management, to the technological development and to the necessity of reduction of the production costs. Today it is no longer its sole objective to repair work tools, but also to anticipate and prevent shortcomings, in order to maximize the overall performance of production, and meet the demands of their customers in term of quality and quantity while respecting delivery times.
