Support is very important for the following 4 areas:

 

- the productivity

 

- the quality

 

- Security

 

- the durability of the goods

 

By limiting the number of failures, the support helps maintain good productivity by reducing the number of creation or child slowdown stops.

 

By limiting the drift of the systems due to aging or wear, the quality of the creation is preserved.

 

By limiting failures, the support makes it possible to prevent certain mishaps

 

By limiting the effects of wear and aging, the support makes it possible to keep the equipment in good condition in addition to a long time and thus allows savings in the purchase of equipment and avoids the problems caused by the integration of new equipment.

 

1.The upkeep restorative, which consists in intervening on a piece of equipment once it has failed.

 

It is subdivided into:

 

Palliative Upkeep: (provisional) troubleshooting of the equipment, allowing it to perform all or part of a required function; however, it must be followed by corrective activity as soon as possible.

 

Corrective Upkeep: repair (sturdy) consisting of an introductory repair.

 

2.The preventive upkeep, which consists in intervening on an equipment before it fails, in an attempt to prevent the failure. We will take preventive action either for reasons of operational safety (the consequences of a failure are unacceptable), or for economic reasons (this is cheaper) or sometimes practical (the equipment is only available for support 'at certain precise minutes). The preventive upkeep is subdivided into child visit into:

 

Systematic, periodic or scheduled Upkeep: they designate operations carried out systematically, either according to a calendar (with fixed time periodicity), or according to a periodicity of use (operating hours, number of units produced, number of movements carried out, and so forth.);

 

Conditional Upkeep: carried out following readings, measurements, checks revealing the state of degradation of the equipment.

 

Forecast Upkeep: carried out following an examination of the evolution of the state of degradation of the equipment.

 

This is the upkeep performed after the detection of a failure, it aims to restore an entity from a failed state to a state allowing it to perform a required function or can be used in addition to support preventive for the elimination of damage.

 

The functioning of the upkeep restorative is divided into two parts:

 

1-Palliative maintenance:

 

The palliative upkeep is a support which is attached to the revision of any episode identified in creation, and preventing the continuation of it, it is a quick mediation to compensate for in addition to critical in chaperone to find an arrangement or a final correction in addition to reassuring.

 

The palliative upkeep allows to:

 

• Locate the incident

 

• Establish an arrangement

 

provisional for continued operation

 

2-Curative maintenance:

 

The upkeep therapeudic is a support which endeavors to correct any episode identified in creation but not preventing its continuation, it is an in-depth and definitive mediation to repair equipment permanently.

 

Upkeep therapeudic allows you to:

 

• Locate the incident

 

• Develop an arrangement

 

to make the machine conform to its goal

 

• Set up this arrangement
