To provide a device for automatically generating a job net configuration file.

Job items are arranged, and a system flow chart and a job flow chart are registered in a database for operating the unitary management of design information (a step 300). The basic design information (data item information definition (1), record information definition (2), and file information definition (3)) is inputted, and registered in a database for operating the unitary management of the design information for generating a job step and a job control sentence (a step 340). Then, the job processing is extracted, and an operation schedule is inputted (a step 360). An operation schedule is registered and changed in the database for operating the unitary management of the design information, and a job net configuration file is generated (a step 370).
