设备双行布置从至表试验法的改进

The Improvement of From-to Matrix Method for Equipment Layout in Two Lines

针对设备双行布置从至表试验法存在的缺陷,提出了改进的从至表试验法.改进后的从至表试验法根据双行设备布置图的特点,运用从至数之和大的居中间区域,小的靠两端区域和关系密切的设备尽可能的近邻,不密切的远离,两条原则结合,用有限的几次试验就可获得比较满意的近似最优解.该方法简便宜行、便于掌握,优化效果良好.

Because of the defects in from-to matrix method used for the equipment layout in two lines,this paper improves the method.The improved method determines the equipment arrangement according to the sum of date on the matrix and the relation of equipment.Therefore there are two principles ： one is that the bigger sum lays in the middle areas and the smaller is in the two sides;another one is equipment with closer relation locates nearer or adjacent,otherwise apart from each other.Combining this two principles,it will be easy to get a satisfactory suboptimum solution with in few trials.
