中厚板坯料优化设计系统研究与应用

Research and Application for Medium Steel Plate-Slab Design System

通过对生产和设计流程的分析,采用分层模块化设计方法,将应用维护、设计管理与数据支撑按不同类型问题分别进行功能模块划分并构建系统的体系结构,开发了中厚板坯料优化设计系统.系统重点解决了生产中涉及的一维和二维两种组合模式下的母板板坯一体化设计问题,综合考虑最小化余材、最大化板坯轧制成材率,提出了结合最优化技术和启发式规则的混合优化设计方法.基于某钢厂的实例数据测试表明,系统在整体设计质量和效率方面均明显优于人工设计.

On the basis of the analysis of the production and design process, a medium steel plate- slab design system （MSPSDS） was built by employing the layered modular design method. The system architecture of MSPSDS was developed by separating the functional moduli for different types of problems including application maintenance, design management and data supporting. MSPSDS focuses on solving steel plate-slab integrated optimal design problems under one and two dimensions. A hybrid solving method was proposed by combining optimization techniques and heuristic rules for minimizing the amount of surplus material and maximizing the rolling yield. The test experiments conducted by using the data instance from a steel plant showed that MSPSDS significantly outperforms manual design both in terms of quality and efficiency.
