The Problem
Spares provisioning is an extremely complex process. Unlike direct materials, typically controlled by MRP or Order Point systems, 80 to 90 per cent of spares provisioning is sporadic, and therefore difficult to manage.
Enterprise resource planning systems (ERPs), Computerized Maintenance Management systems (CMMS) and Enterprise Asset Management systems (EAM) do not support spares provisioning.
The uniquely complex parameters associated with spares provisioning include part-criticality (i.e. the operational impact), multi-location environment, multiple fleet/production lines and budget. The complex relationship between these parameters and the exponential relationship between holding quantities and fill rates/service levels results in a problem with many millions of variables.
Without sophisticated, dedicated tools the spares planner is faced with the impossible task of provisioning for spares in this complex environment, resulting in:
Poor fill rates due to shortages
Poor dispatch rates
Equipment downtime
Over-investment because of surplus and dead stock
Continued purchase of surplus and dead stock
