ABSTRACT:
An operation control system of the invention has an operational graph storage file for storing an operational graph in which unit operation data of items of FA equipment, which performs a series of tasks in association with each other, are arrayed in an execution order, in accordance with work progress states of the items of equipment. An operational graph interpreter reads out the unit operation data from the operational graph storage file, and supplies an operational command to each item of FA equipment, an operational response from each item being detected by a detector. The detector writes an interpretation result, corresponding to an item's operational state, on a blackboard, with reference to an interpretation rule storage file which stores operational responses of the items FA equipment and interpretation results of the corresponding operational states. The operational graph interpreter sequentially selects operations to be executed, with reference to the interpretation results of the operational states of the items of equipment to be controlled, as written in the blackboard.
