Music 3-D Model
Further, the model can be extended to conduct three analyses and arrange in the store room in three dimensions. Consider the two-dimensional model as shown above. In each cell of this model imagine a drawer type in which there will be three or four slots. The first i.e. nearest slot we place fast moving items, in middle slot we keep slow moving items while the third slot contains non moving items. Thus, suppose we pull the drawer of B-V cell, we find B-class, Vital Fast moving items in the first slot, B-class, Vital Slow moving items in second slot and so on. This is pictorially shown in the following diagram.
