• an operation information storage unit storing information about operation locations and machine operation conditions of the machines;
• a maintenance work information storage unit storing information about maintenance work for the machines;
• a user machine information storage unit storing information about machines including machine identifiers assigned by a user of machines;
• an integrated maintenance information storage unit storing information about mapping relations between the provider machine information and the user machine information;
• and
• a user machine inference unit that, for a machine operating in an area for which the mapping relations is going to be inferred, infers an identifier assigned to the machine by the machine provider from the provider machine information, the user information, and the operation information, further infers a machine identifier assigned by the user to the machine with the identifier from the operation information, the user machine information, and the maintenance work information, and stores a mapping relation between the machine identifier assigned by the provider and the machine identifier assigned by the user into the integrated maintenance information storage unit.
