The maintenance function
The function of maintenance is to ensure that plant and equipment are available in a satisfactory condition for operation when required. The determination of what constitutes a 'satisfactory condition' for rotating machinery will depend largely on the operating situation and the following considerations: Type of industry The nature of the industry concerned will determine, to some extent, the level of machine performance required. Process requirements The function of the machine in the process will also determine performance requirements. The requirements of a machine that is critical to the process will be greater than for one that is 'non-critical'. Business objectives Product demand and profit levels may give rise to fluctuating demands on equipment and performance requirements.
