摘要： A rolling mill system associates an autonomous control unit with each piece of equipment in the rolling mill system. The autonomous control unit has a model of the particular piece of equipment, for example, of the rolling mill, a reheat furnace or a cooling bath, and data indicating constraints on the operation of the equipment. A metal shape to be produced is described as a set of machine independent steps, and the performance of these steps is bid upon by the autonomous control units according to the constraint models and internal goals. Bids having conflicting requirements may generate counterbids until a complete plan for the production of the product is generated.

摘要： A rolling mill system uses a number of autonomous control units, each associated with one piece of equipment of the rolling mill system. The autonomious control units include data indicating not only their constraints of operation, but also reflecting the constraints of operation of machines to which they are attached and with which they share common operating parameters. An autonomous control unit associated with a machine having operating parameters in common with another machine of the rolling mill system adopts the intersection of the ranges of the machine constraints of the two machines. Machine constraints are preserved to the extent possible as ranges, so as to permit flexibility in selecting and seeking goals by the individual autonomous control units.

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 include data indicating not only their constraints of operation but also reflecting the constraints of operation of machines to which they are attached and with which they share common operating parameters. An autonomous controller associated with a machine having operating parameters in common with another machine adopts the intersection of the ranges of the machine constraint of the two machines. Machine constraints are preserved to the extent possible as ranges so as to permit flexibility in selecting and seeking goals by the individual autonomous control units.

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.

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 based on given input values and is effectively operated in reverse for external counterbids proposing output values and needing to know input values, or internal counterbids seeking to optimize counterbid input values against output based goals. The reverse modeling iteratively applies inputs to the model until the desired output is attained. The inputs may be constrained by predefined intermediate constraints and may be changed in a binary search pattern. In multi-input models, one input may be specified for iteration.
