In an apparatus for generating and managing production processing structure in a production management system of a factory, the structure of factory made up of the names or other identifiers of process points obtained by subdividing the factory production line is hierarchically registered in the storage device of the management computer (server; S200), the terminal computers and devices used in production are registered as terminal devices (S202), and tasks (from among tasks generated in advance and stored in the disk of the management computer) for achieving the operation or processing to be implemented at the process points are selected for each process point and registered in the order of execution (S204), while linking the terminal devices with definition information that correlates them, once the terminal computers are activated, the registered tasks are executed by the management computer (server) based on the definition information thus registered, so that the production record information is accumulated, production instructions are distributed to the devices based on the accumulated production record information, such that the product is produced. With this, the number of man-hours and the costs of developing the production management system in building a factory can be significantly reduced, and the turnaround time can be shortened.
