Title:
COAL BLENDING METHOD, SYSTEM, APPARATUS AND STORAGE MEDIUM BASED ON ROBUST OPTIMIZATION
Document Type and Number:
Japanese Patent JP2023021917
Kind Code:
A
Abstract:
To provide a coal blending method, a system, an apparatus, and a storage medium that incorporate an interfering factor affecting a coal quality parameter into modeling, adopt robust optimization, perform optimization in a set of given interfering factors by the robust optimization, find a solution on the assumption that a distribution of parameters of interfering factors for finding an optimum plan in the worst case cannot be known, allow a user to further obtain a corresponding optimum plan by combining risks and benefits, and find a corresponding plan by adjusting a boundary of the interfering factor.SOLUTION: A coal blending method includes the steps of: acquiring at least one interfering factor affecting coal quality; building a coal quality model under influence of the interfering factor, including a coal quality parameter model for single coal, a quality index model for blended coal, and a quality index model for coke; and finding a solution for the coal quality model based on constraints and a plurality of optimization goals to obtain an optimum coal blending plan corresponding to each optimization goal.SELECTED DRAWING: Figure 1
