Embodiment Construction
[0031] The present invention will be further described below in conjunction with the specific embodiments of the accompanying drawings and the material classification coding of aerospace product structural parts:
[0032] Such as figure 1 The shown multi-dimensional classification setting process is divided into four steps: determining the scope, analyzing the application occasion, determining the classification dimension, and determining the classification basis attribute of each dimension.
[0033] (1) Determine the scope
[0034] In this example, materials such as raw materials, auxiliary materials, and standard parts of structural parts of aerospace products are used as the range of classification codes.
[0035] (2) Analyzing application occasions
[0036] The types of work related to this classification code include product design, process design and management, model project management, financial management, quality management, procurement management, warehouse manage...

The invention provides a manufacture information multi-dimension classification coding method for an aerospace product structural element. The method comprises four parts: a multi-dimension classification setting flow process, a multi-dimension coding rule, a multi-coding-system coexistence method and coder structure setting, and each part is in independent arrangement according to requirements. The method provided by the invention solves the problems that the single classification cannot meet the requirements of multiple application occasions, and the coding volume is limited. The multi-dimension classification is adopted for being matched with different application requirements. The method can be used for the manufacture information classification coding management of the aerospace product structural element and the development on product data management (PDM) / enterprise resource planning (ERP) / manufacturing execution system (MES) systems and can be popularized and applied to the classification coding of other information. The method has the advantages that the multi-classification setting can be realized, the classification requirements of the multiple application occasions can be precisely met, the compatibility with other classification systems can be realized, the coding in each dimension can realize the independent change, the coding volume limitation is avoided, the coding is simple and is easy to use, and the like.
Description
technical field [0001] The invention relates to the technical field of classification and coding, in particular to a multi-dimensional classification and coding method for manufacturing information of aerospace product structural parts, which can set multiple classifications and is compatible with other classification systems. Background technique [0002] Classification and coding are necessary basic data for scientific research and production of aerospace products. Currently available standards include "Q / QJA 39 Aerospace Model Coding Rules" and "GBT 7027-2002 Basic Principles and Methods of Information Classification and Coding". The characteristics of the existing classification and coding system and norms are that the code is used as the identification, and the information can only follow one classification and coding system, and there is only one classification and coding. The problems faced include: [0003] (1) There are many coding systems and difficult to convert...
