Relationship Diagram Drawing for Power Materials Based on Entropy Analysis
Material relationship diagram(MRD)is a brand-new technical toolkit for lean management in power enterprise.It includes match,measure and timeliness relations and provides various knowledge support for material standardization system.Typically,MRD drawing requires sample denoise for quality assurance.This paper presents a noise reduction method that is based on entropy analysis.The method can achieve automatic data cleaning and solve the problem that extremly demands for experts in traditonal method.
