goal coordination method

goal coordination method

[′gōl kȯ‚ȯrd·ə·nā·shən ‚meth·əd]
(control systems)
A method for coordinating the subproblem solutions in plant decomposition, in which Lagrange multipliers enter into the subsystem cost functions as shadow prices, and these are adjusted by the second-level controller in an iterative procedure which culminates (if the method is applicable) in the satisfaction of the subsystem coupling relationships. Also known as interaction balance method; nonfeasible method.
