Manufacturing Enterprise Information Coding System Technology Research

In recent years, the theories, methods and techniques of integration of the manufacturing enterprise information system have been gradually maturing, but the research of technique and method at propping up the system to integrate and the information to share is still weak. For example, the standard technology of information has become the "bottleneck" of the enterprise information integration. In this thesis, information classification and coding technique is studied, emphasized in information expression standardization in the manufacturing enterprise system integration, combined the requirement of the CAPP, PDM, ERP and SCM system integration.This thesis presents the system theories of the information classification coding, analyzes the requirements of system integration to foundation data of the manufacturing enterprise, studies how to establish the information coding system, establishes a flexible coding structure model based on object-oriented technology, establishes the conversion model between old and new coding system, and designs the function and structure of the information coding system.Main research results are as follows:1. Through the research of information resource in the manufacturing enterpriseand system integration relation, the total requirement model of the system integration to the information resources is established, and the research object of the manufacturing enterprise information coding system is indicated in this thesis.2. A kind of coding structure is established, which is based on object-orientedtechnology, faces the whole manufacturing enterprise, uses a uniform structure form, and is a flexible coding structure model. This model combined the advantage of the existing coding system, including the ratings, layering, flexible structure, and object-oriented technology, so which is widely adaptive.3. The conversion model between old and new coding system is established.4. The software structure model of the information coding system (XAC-MICS) is Designed and the thesis realizes parts system functions.
