Online Strategy for Scheduling By-Product Gas Consumption and Adjusting Gas Holder Level in Iron and Steel Industry

Abstract:

The more efficient use of by-product gas has always been a hot issue in the iron and steel making process. The gas generated during production process is stochastic and hardly predicted accurately. Specifically, how to regulate the supply of by-product gas from gas holder to power plant in the scheduling period to maximize the total profit of gas reutilization is present work. In response to this objective, online algorithm will be applied here to analyses the optimal strategy, which manages the by-product gas supply scheduling in term of online strategy and competitive analysis. We give the competitive ratio’s lower bound of the problem, and analyze the properties of algorithms, then give the QEW-algorithm with a competitive ratio equals to γ/(γ-β). The results of the study have guiding significance and reference value to decision makers facing the actual production process.
