Abstract: 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.
