摘要

针对中厚板生产订单具有的多品种、多规格、小批量等特点,致使其组板及板坯设计存在难度大的问题,充分利用非定尺生产订单及板坯规格的不确定性建立适应性组合优化模型,实现一维和二维、定尺与非定尺的中厚板组板及板坯集成优化设计,并构建相应的模型软件系统。利用某钢厂生产订单数据的应用测试表明,模型设计结果相比与人工设计、标准遗传算法具有成材率提高、余材率明显降低、设计效率显著提升的效果;改变生产订单规模和特征的仿真试验进一步显示出模型及系统的设计质量提升效果。

Abstract

The production orders of medium steel plate always come in small batches of various types and specifications,leading to difficulties for steel plants in combining the order plates into the mother plate and designing the slab. By making full use of the non-fixed length production orders and the uncertainty of slab specifications,an adaptive combination-optimization model is established to realize the integrated optimization design of mother plate and slab for orders of both one-dimensional and two-dimensional,and of both fixed length orders and non-fixed length. A corresponding software system is developed and tested against the production order data from a steel plant. The results show that the design generated by this model features has higher product yield and lower surplus material rate than the artificial design and standard genetic algorithm. The design efficiency is significantly improved as well. These improvements in the quality of design are further demonstrated by simulative experiments on the modified scale and characteristics of production orders.
