FOR A BETTER CONTROL OF THE AVAILABILITY OF THE INDUSTRIAL EQUIPMENTS
Journal Title: RECENT - Year 2010, Vol 11, Issue 1
Abstract
Each one can intuitively understand that maintenance is significant because if equipment breaks down, the production can be stopped. In a system with tended flows or there are few intermediate stocks, such a stop can put in layoff part of the workers and thus to have very expensive consequences. thus, the stoppage or the abnormal operation of the production equipment, and the non-observance of the deadlines which is followed from there, indeed generate costs which the companies are not any more in a position to support: wastes of time, losses of production, thus affect the costs, then losses of credibility near the customers, therefore affect competition and the confidence and finally losses of profitability and competitiveness, even losses of perenniality. This is why; the companies cannot wait any more until the breakdown occurs to cure it but must from now on be organized to proceed to the various operations, which make it possible to avoid it. Thus in the company, the function "maintenance" less and less often consists in giving in state the working tool but to more and more frequently anticipate its dysfunctions. Therefore, it is not advisable to develop immediately all good practices. Some can be more urgent than others, according to priorities' of the company. Indeed, if the maintenance activities are correctly planned, one can better prepare the tools and the necessary parts as well as the team concerned to the various interventions, even a better coordination between maintenance and production. This is why the objective of this work is the early detection of the dysfunctions of the critical machines, even the intervention advisedly, while following the evolution in the time of the symptoms of state drift of the equipment. Thus, one is able to rationally use the mechanical components until complete wear without any risk of sudden breakage and to practice selective maintenance.
