PROBLEM TO BE SOLVED: To prevent double managements of information and to allow other devices to easily refer to and utilize information held by a scheduling device by unitarily managing definition information that is needed to perform scheduling as shared resources. SOLUTION: When a host production plan system 1 makes out a production plan, a scheduling device 2 produces an operation plan for realizing the production plan. A batch plant control system 3 performs a control operation according to the operation plan produced by the device 2, operates a batch plant PLT. A recipe managing device 4 and a production information managing device 5 store definition information that is necessary to perform scheduling in a preliminarily defined data structure, the device 4 stores recipes and the device 5 stores resource information and plant information. The stored information is unitarily managed as shared resources so that the device 2 and the system 3 can utilize it. |
