Optimization of supply chain in iron and steel industry based on pre flow advancing network flow algorithm and computer simulation

Under the relatively mature background of the iron and steel industry, the focus of industrial optimization is focused on the optimization of the logistics supply chain. In this paper, a large amount of data is extracted from the preventive maintenance inspection of the iron and steel industry supply chain, and a model to improve the transportation efficiency and test the maximum production and transportation capacity is constructed. Using the pre-flow propulsion network flow algorithm to solve the problem at high speed, it aims to quickly solve the model target value under the dynamic and diverse conditions. Taking the simulated industry situation in Zhejiang as an example, the network transport flow model and method proposed in this paper are verified to solve the problem of supply chain optimization and calculation in the iron and steel industry.
