Maintenance Management Module
The primary purpose of this module is to record the different maintenance activities performed on a
machine and thereby generate information on the performance of a machine. Other related actvities
like recording the usage of spares in different sections and tracking the movement of spares from one
section to another may also be done.
When maintenance work is required on a machine, a person from the particular section where the
machine is installed has to enter the machine handover details. On entering the machine number, the
computer cross checks the validity of the machine number and the machine description and section
are automatically displayed. The type of maintenance (electrical, electronic, mechanical etc)
involved must be entered. Maintenance transactions are to be registered for breakdown as well as
preventive maintenance.
Once the machine has been handed over for maintenace, the maintenance section should register the
planned date of completion of the maintenance activity.
When the maintenance work is over, the restoration details are to be recorded. The number of
persons involved in each grade and the number of hours worked has to be entered for each grade of
labour involved in the maintenance activity. The labour cost is calculated and recorded.
Once the preventive maintenance activities on each machine have been identified,the preventive
maintenace schedule should be planned for a given period. The period for which the preventive
maintenance activities have been planned should be entered. Then for each machine scheduled date
of the preventive maintenance should be entered. The scheduled date should not exceed the plan
period. This actvity needs to be done after every plan period.
The different preventive maintenance activities that are to be done on each machine are identified
and registered. The interval after which the activity needs to be done again and the expected duration
in hours is to be entered.
Once a preventive maintenance has been done on a machine, the date when the same activity is to be
done again is to be recorded.
The available stock of spares in a section must be initialized. Whenever a certain quantity of a spare
is required in a section, it may either be drawn from the main stores against a demand note or it may
be obtained from another section where it is available. The sectional stock of that spare is then
updated.
Whenever a spare is transferred from one section to another, the transfer details must be recorded.
The quantity is then reduced from the sending section whilst the quantity of that spare is increased in
the receiving section.
The quantity of spare material used in a maintenance activity must be recorded before the machine is
restored back in the section. The material cost is calculated and recorded by the system. This may be
used to generate the total maintenance cost for a particular machine.
