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.
