摘要:
An industrial control system uses a number of autonomous control units, each associated with one piece of equipment in an industrial process. The autonomous control units negotiate by bidding among themselves to determine a common set of input and output values for the interconnected machines with which they are associated. Each autonomous control unit determines whether input values are acceptable by using a model of its associated equipment. The model provides anticipated output values which may be compared against a predetermined range of outputs of associated machines, outputs compatible with downstream machines, or the constraints of the overall industrial process according to a designated job to be accomplished. Optimization of the input and output values is provided by allowing preliminary bids to be the subject of optimizing counter-bids if the original bid value could have been accepted.

Provided is a method and an arrangement for enabling a processing step for an object that is to be processed, wherein an availability result, which indicates an availability of the processing step, is determined for the processing step on the basis of rules.
摘要:
An industrial control system associates an autonomous control unit with each piece of equipment in an industrial process, the autonomous control units having a model of the equipment's operation and data indicating constraints on the equipment's operation. A product to be produced is abstracted as a set of machine independent steps and performance of these steps bid upon by the autonomous control units according constraints models and internal goals. Bids having conflicting requirements may generate counterbids until a completed plan for the production of the product is generated.
