Problems solved by technology

However, due to the complexity, nonlinearity, multi-objective, and multi-constraint characteristics of the model, it is difficult for the traditional linear programming method to calculate large-scale parameters. Therefore, this method is relatively powerless in the face of large-scale or unclear mechanisms.
