ABC approach based on important degrees is a method on the basis of statistical inventory information and important degrees of spare parts,resulting in a suitable spare parts inventory,thereby overcoming ABC approach s limitation of non-considering important degrees for the spare parts,to avoid leaking important spare parts.
