Optimization of the maintenance function in an ERP environment

The ERP/MRP system, generally regarded as one of the most widely used systems for production, has encompassed all aspects of manufacturing operations except for the maintenance function. Hence the maintenance system runs in parallel to the ERP/MRP system performing similar activities like scheduling, capacity planning and purchasing. Having production and maintenance controlled by a single system instead of two separate systems could be expected to be more efficient, to provide superior planning control and smoother operations. This has been recognized and several models for part integration of activities like purchasing have been developed. However they have fallen far short of total integration. This paper investigates the unique problems facing total integration of maintenance into the ERP/MRP production system. It then suggests methods by which these problems can be overcome to deliver a highly efficient fully integrated Maintenance ERP/MRP System.
