Embodiment Construction

[0042] In the field of intelligent manufacturing technology, the Stackelberg game model with equilibrium constraints has a wide range of applications, and can abstract certain problems into a very common MPVCC optimization model. However, due to the special structure of the equilibrium constraint, it is very difficult in the algorithm and cannot be directly calculated. For example, consider a Stackelberg game problem with equilibrium constraints abstracted from the practical problem

[0043]

[0044] where y∈SOL(z) is an equilibrium constraint. This model is difficult to solve directly, so it is equivalently transformed into a t-MPVCC problem according to the method of the present invention, and becomes a general nonlinear programming after applying a classic relaxation model, which can be effectively solved by software.

Abstract

The invention relates to a relaxation method for optimization of an intelligent manufacturing controller unit based on an equilibrium constraint programming problem. The relaxation method can solve a C-stable point of MPVCC mathematical programming including vertical complementarity constraints and no longer assumes a KKT point, and an algorithm conforms to a termination criterion. The method is based on t-MPVCC mathematical programming, utilizes an MPVCC-MFCQ constraint specification to solve an approximate KKT point, replaces the KKT point with the approximate KKT point to solve an MPVCC programming problem and proves that a theoretical result is true under the MPVCC-MFCQ constraint specification, the algorithm is effective, and the method solves a problem of controlling computation of application software.
