Before applying the forecasting techniques, a support vector classifier was first used to classify the data, and then the filtering was used to create separate trend and volatility sequences. After forecasting, the Markov chain transition probability matrix was introduced to adjust the residual. Simulation results using surplus gas data from an iron and steel enterprise demonstrate that the constructed SVC-HP-ENN-LSSVM-MC prediction model prediction is accurate, and that the classification accuracy is high under different conditions. Based on this, the scheduling model was constructed for surplus gas operating, and it has been used to investigate the comprehensive measures for managing the operational probabilistic risk and optimize the economic benefit at various working conditions and implementations. It has extended the concepts of traditional surplus gas dispatching systems, and provides a method for enterprises to determine optimal schedules.展开更多

Focusing on scale expansion, adhering to the ＇open-to-the-world＇, self-integration and self-innovation policies,and keeping up with the development of processing equipment and production technologies ,Baosteel has successfully shifted its strategies from ＂premium products＂ to ＂premium products plus scale expansion＂, and from ＂building new production lines＂ to ＂merging and restructuring plus building new production lines ＂. These strategies have greatly enhanced Baosteel＇s comprehensive competitiveness and speeded up its sustainable development. On a new stage of development, Baosteel will choose an open mode of self-integration and self-innovation, which lays emphasis on improving its technological capacity by ＂internal creation＂ and ＂external acquisition＂ ,to develop a recycling economy. Through correctly balancing the relationship between scale expansion and environmental protection, Baosteel will constantly improve its core competitiveness, keep corporate and social development in perfect harmony,produce better steel products and create a sound environment and a better life.展开更多
