价值分析中选择VA对象之最合适区域法的新探索

The select of V Aobjects in value analysis plays an very important role.From the angle of cost-saving,this paper introduces a new method called equall-valued segments of straight line,which concentrates on the region in which the value coefficients of every point is smaller than 1,according to different degree of cost-saving and practical needs,divides it into a series of meaningful small regions,on the basis of that,points out not only the fault of generally accepted Mr.Danaka‘s method of the ‘most reasonable region’,but also provides a new way for identifying the real and practical ‘most reasonable region ’．
