摘要：An accurate and effective scheduling of byproduct gas in steel industry is significant for cost reduction and environment protection. In this study, a target-oriented granular inference method is proposed for realizing real-time scheduling of converter gas system, in which the fluctuation characteristics of the flow of the gas users are considered for data granulation, and then granular inference is performed to construct the scheduling rules between the gas users and the system scheduling amount. To fully reflect the impact of scheduling objectives on the modeling process, a target value is proposed to be included in each rule and being further updated by employing residual gradient Q-learning method, which is used to select appropriate scheduling policies from inconsistent fuzzy rules. On their basis, the scheduling rule base is updated online by utilizing evolutionary computation method. To demonstrate the effectiveness of the proposed method, the practical data coming from the energy center of a large-sized steel industry are employed, the results indicate that the proposed model could guarantee a higher accuracy and make the operation of converter gas system safe and stable.
