针对炼钢大规模批量化生产与后工序多流向对品种规格多样性需求的矛盾,研究了炼钢流向平衡问题,提出了基于智能决策的计划优化方法,以提升全流程生产的连续性和稳定性.分析了流向平衡问题的工艺规则和优化指标,建立了精准描述问题结构的混合整数规划模型.为实现大规模问题的高效求解,提出了改进禁忌搜索算法,设计了避免算法陷入局部最优的多种邻域结构和扰动因子.对不同规模的实际算例进行了数值试验,结果显示,所提出的改进禁忌搜索算法在解的质量和收敛性方面较标准求解器CPLEX和常规禁忌搜索算法有显著性改进,且优于人工经验决策方法,能够基本满足流向平衡智能决策的需求.
Optimization of steelmaking flow balance plan based on intelligent decision-making
To address the challenge posed by the contradiction between the large-scale mass produc-tion in steelmaking and the demand for variety and specification diversity in subsequent processes,a study on the steelmaking flow balance problem was conducted.An optimization method based on in-telligent decision-making was proposed to enhance the overall production process's continuity and stability.The approach involved analyzing the process rules and technical indicators that needed opti-mization to achieve flow balance in steelmaking.To accurately represent the problem structure,a mixed-integer programming model was developed.Recognizing the need for efficient solutions,espe-cially for large-scale problems,an enhanced tabu search algorithm was introduced.This algorithm in-corporates multiple neighborhood structures and disturbance factors to prevent it from getting trapped in local optima.Numerical experiments were conducted on practical instances of varying scales,and the results indicate significant improvements in solution quality and convergence of the proposed en-hanced tabusearch algorithm compared to the standard solver CPLEX and conventional tabu search algorithms.Furthermore,it outperforms manual decision method and can basically meet the needs of flow balance intelligent decision-making.
