1. A production facilities monitoring method for monitoring an operation status of a plurality of production facilities of a same kind located at a plurality of production sites, the production facilities monitoring method comprising:
a data information preparation step of aggregating operational data of each of the production facilities for each of the production sites;
a data accumulation step of accumulating the operational data aggregated at the data information preparation step into a computer located at a data accumulation site;
a data analysis step of analyzing a current operation status at each of the production facilities, using current operational data and past operational data accumulated at the data accumulation step; and
an operation status determination step of determining whether operation is abnormal at each of the production facilities, based on an analysis result of the data analysis step.
