在轧钢生产中,不同外径的钢管需要用具有相应加工直径的三辊机架来加工。而具有加工直径D的三辊机架可以通过对具有加工直径比D小的旧三辊机架的改造而获得。因此,对下一个计划周期的加工需求,需要通过改造获得所需要的三辊机架。以总加工量最小为目标,满足生产需求为约束,建立了一个整数规划模型。根据所建立的模型,开发了基于遗传算法的求解方法。数据试验表明了算法的有效性。

In steel tube rolling,the key equipment is 3-roll-stand-set,which has its processing diameter.Steel tubes with a given outside diameter should be produced by a 3-roll-stand-set that has the corresponding processing diameter.A 3-roll-stand-set with processing diameter D can be obtained by rebuilding a used one with processing diameter less than D.Thus,3-roll-stand-set should be prepared to meet the production requirements for the coming scheduling horizon.An integer programming model is developed for 3-roll-stand-set rebuilding to minimize the manufacturing time such that production requirements can be met.With the model,genetic algorithm is presented to solve the problem.A practical application example is given to show the effectiveness of the proposed method.
