Abstract

The invention discloses a conflict data processing method and device based on operation planning optimization, a terminal and a medium, and the method comprises the steps: analyzing the constraint characteristics of a current model when the calculation of the current model of a security constraint unit combination finds that there is conflict data, obtaining a high-coupling constraint, adding a slack variable for the high-coupling constraint, and carrying out the optimization of the slack variable; performing one-by-one relaxation solution; the relaxation model is solved through a solver, if the model has a solution, the minimum relaxation amount of the high-coupling constraints is returned, if no solution exists, other high-coupling constraints continue to be relaxed until no solution exists when all high-coupling constraints are relaxed, analysis is conducted according to a minimum conflict set, and data information of conflicts existing in the current model is obtained; and adjusting the current model. Therefore, according to the embodiment of the invention, the problems of low calculation efficiency and difficulty in conflict positioning when high coupling constraints are processed can be solved by analyzing the constraint characteristics of the security constraint unit combination, identifying the high coupling constraints in the model and performing one-by-one relaxation solution in combination with the solver.
