X71: Preventive Maintenance

SAP AG 2007, SAP Best Practices for Mining V1.600 X71 Preventive Maintenance, 2

X71 - PREVENTIVE_MAINTENANCE Overview (time-, usage-, & condition based)

Highlights:

The three preventive maintenance processes, time-, usage-, and condition

based, are described

Generating a cost report for time- and usage based preventive maintenance is

shown

Integration:

Integration to the corrective maintenance process is shown

Time- and usage based preventive maintenance plans are key inputs to the maintenance cost budgeting process

Process Overview: Industry: Mining The preventive maintenance scenario demonstrates three preventive maintenance

processes. It describes how to create and schedule a maintenance plan based on

elapsed time and based on usage, and how to generate a planned cost report. It further

describes how maintenance is trigged based on the condition of a unit. Maintenance based on elapsed time: Since time does not provide the optimal schedule for

maintaining equipment that requires maintenance due to operational wear, it is usually used to

schedule inspection activities and periodic testing (e.g. pressure vessel tests)

Maintenance based on the usage of plant and equipment is a common and important maintenance strategy to enable the optimisation of the maintenance frequencies. Maintenance

requirements are generated from equipment usage information, i.e. engine hours

Condition based maintenance is the third method used to drive the creation of preventive maintenance work. Requests for maintenance are generated from condition readings entered

into SAP
