Classifying and coding system of turbine parts based on internal and external codes

Abstract

Based on the smooth implementation of PDM in enterprises, this paper focuses on the system structure of classification and coding system, puts forward the concept of internal and external codes, and develops a product classification and coding system based on internal and external codes with reference to various classification coding systems at home and abroad. Internal and external codes are used separately in different department of the enterprise and their function is different, so it can solve the past problem of long codes and make the value of every code fully utilized. It is shown from the application that internal and external codes can meet the requirements of PDM for the classification and coding of turbine parts and contribute to its successful implementation in the enterprises.
