Natural gas supply chain flow distribution method

The invention discloses a natural gas supply chain flow distribution method, which comprises the following steps of: classifying natural gas users, and determining a gas supply amount weight of each type of users; constructing an optimization model objective function by taking the maximum weighted gas supply amount as an optimization objective; and determining constraint conditions of the optimization model based on the injection-production capacity of the gas storage, solving the optimization model, and outputting a natural gas supply chain flow distribution scheme. According to the method, the technological process of the gas storage is analyzed, influence factors influencing the gas injection and production capacity of the gas storage are determined, and a gas injection and production capacity calculation method of the gas storage is established; user grading is carried out on users, weights of different users are determined, an optimization target with the maximum weighted gas supply amount is established
