Contribution à l'amelioration des pérformances opérationnelles des machines industrielles.

Abstract

The companies should maintain the production equipment in good condition and reduce the frequency and the duration of the service accidental interruptions at the same time. In order to prevent the process performance loss, it is to set up a maintenance management system able to increase the equipment availability, and to guarantee the workstation performance. This search led to several interesting contributions in the field of maintenance, and introduced a new vision which makes it possible to contribute to competitiveness companies independently of their size. The work has began by the study of the various factors which act on the performance operational of the industrial machines that is the methods or tools, then the three approaches of the maintenance management methods were applied. The optimization of maintenance by the AMDEC is an approach which enables us to classify the causes according to effects' which they generate and to deduce the actions priorities to be carried out. The RBM (reliability-based maintenance) is a genuine design tool of the preventive maintenance, having for goal the reliability and the security of the production means taking into account the economic aspects. La TPM (Total Productive Maintenance) it is an improvement approach of the total productivity of the of production system by a better implication of all the company personnel in the function maintenance. The performance indicators constitute privileged representations for the decisionmaking by anticipation. The main indicator of the TPM is the OEE (Overall Equipment Effectiveness) which integrates several factors indicating the total equipment operation, has led to determine the efficiency of a production means. The strategies developed here can be applied advantageously in all industrial sectors
