Maintenance management system for managing maintenance of components of assembly apparatus

An assembly apparatus including members having maintenance items to be maintained at predetermined maintenance time intervals, the apparatus comprising:

• input means for inputting a selected maintenance time interval;
• a storage unit for storing the maintenance items and the maintenance time intervals of each of the members;
• a time information generation unit for producing time information starting from a certain reference time and for outputting a time information signal, wherein the time information includes time of day, calendar day, day of the week, and month and the reference time is one of a time of installation of each of the members or a most regent time of maintenance of each of the members;
• and
• a comparing unit for comparing the selected maintenance time interval input by the input means with the maintenance intervals stored in the storage unit and outputting all maintenance items corresponding to the selected maintenance time interval, wherein the comparing unit further receives the time information signal from the time information generation unit, compares the time information signal with the maintenance intervals stored in the storage unit, and, when the time information signal corresponds to a maintenance interval, outputs an alert signal alerting a user that a corresponding maintenance item is due to be maintained.
