Abstract
A timely and effective scheduling of the byproduct gas system plays a pivotal role in realizing intelligent manufacturing and energy conservation in the steel industry. In order to realize real-time dynamic scheduling of the blast furnace gas (BFG) system, a granular prediction and dynamic scheduling process based on adaptive dynamic programming is proposed in this paper. To reflect the specificity of production reflected in the fluctuation of data, a series of information granules is constructed and described. In the dynamic scheduling phase, based on the granular feature description, a scheduling action network is established and further updates of information granules are realized. Considering a slow adjustment process and delay characteristics of the BFG system, the cumulative reward of the critic network is calculated on the basis of the data partition to construct a tendency attenuation-based cost function. In order to determine the future trends of the gas tank level that targets real-time determination of the scheduling moment, a reinforcement learning-based granulation and prediction process is also proposed. To demonstrate the performance of the proposed method, a number of comparative experiments are presented by using the practical industrial data. The results indicate that the proposed method exhibits high accuracy and can deliver an effective solution to justified scheduling of the BFG system.
