The invention relates to a method for optimizing the distribution of oxygen production system in iron and steel enterprises, which belongs to the technical field of oxygen system scheduling. The equation established in the first stage refers to the regulation quantity to reduce or increase the pressure to the specified range, and considers the dispersion of users. In the second stage, according to the demand characteristics of different users, the aerobic users are divided into stable users and fluctuating users, the overall pressure constraint is determined, and the constraint equation is established. By solving the model, the global optimal solution or the bound of the optimal solution of the assignment problem can be obtained. The solution algorithm plans the distribution scheme through the optimal solution, which can provide the best solution to the oxygen distribution problem. The advantage is that the efficiency of direct distribution to users through this method is high, and the pressure of oxygen pipe network in the process of oxygen dispatching is within the specified range, so as to improve the utilization rate of oxygen and save energy.
