Predictive Maintenance

Hi Experts

Need SAP Best Practices / scenarios for Predictive maintenance with flows.

Thanks & Regards

I'm not sure for best practices availability for this business process. You will have to activate user exit for actually using this process in SAP. Say you are measuring vibration readings as measuring points. Now under measuring points, you have also defined the upper and lower limits.

When you create measurement documents for this point and if it is crossing the upper limit, system warns you under normal scenario. If you have activated this user exit i.e. IMRC0001, you would be able to ask system to perform next step like creating maintenance notification or notification with order, etc. This is extremely useful, if you have some plant control room system feeding vibration readings on real time basis. In such scenario, you would be able to utilize this business process very well.

Hi Ketich

Thanks for the reply as per http://help.sap.com/bp_miningv1600/Mining_AU/Html/X71_EN_AU.htm

the process explained by you becomes condition based maintenance. I need a flow for predictive maintenance.

Thanks again

Can you explain me the difference between Predictive and Condition based?

Hi Ketul

Is Predictive and condition based same ? This thread is for knowing the same, as one of our client wanted to know the SAP flows for both.

Thanks

Hi,

Predictive maintenance, as implied, is to look into future and anticipating the break downs. This type of preventive maintenance came into play from TPM (Total Productive Maintenance), which envisages 100% availability of equipment.

Take the following example to understand the procedures:

The manufacturer recommends replacement of a rotating component- a bearing for example, to be replaced every 1000 operating hours. By adapting proper preventive maintenance techniques, there is a possibility that the bearing has not worn out at 1000 operating hours, as predicted by manufacturer, who would have taken the avarage working environment of the equipment.

Here predictive measures come into play, which have been made available by latest innovations and the associated technical standards, which specify new tolerances for rotating machinery, to ascertain the health of the component.

Hence Vibration analysis, Fluid analysis -to name a few, came into play.

Based on the result, and experience, the change frequency of 1000 operating hours will be extended by say, 250 hours, after which the required analysis is carried out once again.

Subsequent analysis may determine the life of the bearing to say, 1750 operating hours.Up to this stage, predictive maintenance rules.

Henceforth, condition based maintenance takes over, which will stipulate a vibration analysis at 1500 hours and a change of component at 1750 hours.

Ultimately, the equipment availability is increased, un expected break downs are avoided and maintenance cost comes down.

By the above example, it is clear that the predictive maintenance precedes condition based maintenance.

It is up to the consultant to decide the method of adaption to implement the above sequences in SAP.

Sorry, Your explanation on predictive and condition based maintenance is not clear.

Hi,

SAP scenario is not different than other maintenance scenarios, the main difference lies that whenever you use any predictive tool (say Vibrometer, or critical temp detector), then you use such maintenance order.

thanks.
