<p>PROBLEM TO BE SOLVED: To easily search data in a product unit and a device unit by arranging a data holding means for storing data collected in a production process by a product agent. SOLUTION: A product agent 50 moves on a production line of a factory according to a production procedure, and returns up to the data control part 100 by holding data collected in the factory. The product agent 50 writes data 51 held by itself in a database of a data holding means 101. Device agents 60a, 60b register data 61a, 61b collected in the prescribed timing in the database of the data holding means 101. Since the device agents are arranged so as to correspond one to one to a machine tool, data held by the device agents is data on a certain machine tool. Thus, data classified with every product and device is obtained from the data held by the product agent and the device agents.</p> |
