System, method, computer program, and recording medium for machine-management

A management system of a machine, comprising:

• a client terminal and a server that connects to the client terminal through a network, wherein
• the client server includes an input means for entering a model of machine under a maintenance contract, a contract rank, and a maintenance actual result value, a display means, and a control means that requests data from the server and represents the data transmitted from the server on the display means;
• and
• the server includes a maintenance rank table organized by model that stores a maintenance predicted value with respect to a maintenance of each machine's model within a contract time for two or more contract ranks for each of one or more models, a means for storing a maintenance actual result value, which accumulatively stores the maintenance actual result value of the machine entered from the client terminal, and a means for determining whether the maintenance actual result value is larger than the maintenance predicted value after an expiration of the contract of the machine,
• wherein the maintenance predicted value, which corresponds to the machine's model and the contract rank, is read out from the maintenance rank table and the maintenance actual result value is read out from the means for storing the maintenance actual value.

A management method of a machine, comprising the steps of:

• storing a maintenance predicted value with respect to a maintenance in a maintenance rank table organized by model in a contract time period for two or more contract ranks for each of one or more models;
• storing the model of a machine under maintenance contract, contract rank, and maintenance actual result value, where the maintenance actual result value of the machine is accumulatively stored in a means for storing the maintenance actual result,
• reading the maintenance actual result value out of the means for storing the maintenance actual result value and reading a maintenance predicted value out of the machine maintenance rank table organized by model, where the maintenance predicted value corresponds to the machine's model and the contract rank after an expiration of the contract of the machine;
• and
• determining whether the maintenance actual result value is larger than the maintenance predicted value.
