Many enterprises in the information-oriented construction process, the role of information classification and coding standardization lack of knowledge, often paid attention to hardware configuration and software development, but never paid much attention to the information that way. The functions of information naming, description, classification and coding, etc., in full accordance with their needs and habits to be. Classification and coding catalog content than the chaos, are not compatible, it is difficult to meet the requirements of modern information management, which will inevitably seriously affect system operation and maintenance.
Much of the information system failures, however, some attention is the absence of information system coding. This is mainly domestic scientific theory is not a complete guide to the classification and coding standardization of the lack of adequate understanding. In the name of some non-uniform internal information, information classification is not uniform, the same information on the calculation and measurement units are not uniform and so on are common occurrences. In addition, the nature of the information classification and coding the same standard-setting, business, departments often do not communicate with each other, their own way, without regard to the compatibility and interface standards. Once the system is set up, if reversed in, inevitably waste a lot of manpower and material resources.
In some foreign countries, information system, is focused on the classification and coding methods of optimization, systems analysis and overall planning. If the establishment of a modern material coding system that can ensure the material design, manufacturing, procurement, storage, transport and other business normal operation, avoid unnecessary waste and losses, can promote the exchange of information materials to improve material utilization, accelerate cash flow, save the procurement of funds, reserve funds to reduce occupancy. Information Classification and Coding Standardization visible economic and social benefits are obvious, of great significance.
First, the coding status of petrochemical materials
China Petrochemical Material Code and the product code from the last century 80's, after more than ten years, has been amended several times and released, each formed a management and application system. Material Code classification with reference to national standards, the former Ministry of Textiles (39 categories), Ministry of Chemical Industry (45 categories), the Ministry of Oil (52 categories) classification, is now using the revised 2000 classification and coding, a total of 56 major categories, low 16-bit code compiled into 10 categories of goods 120 000 or so. Product Code reference to the National Bureau of Statistics classification standard has been continuously added, there are about 40,000 with about coding.
These two sets of classification and coding in general is scientific and reasonable, for the production and management, materials supply management, statistics and information products and construction materials has played an important role in promoting China's Sinopec for the ERP system application management reform and laid an important foundation. However, as China Petrochemical deepening of information technology, products, purchase prices, suppliers, inventory reserves, and other management reform deepens, the existing coding there are not compatible to the main issues reflected in:
(1) coding does not achieve centralized management. Only 10 categories of material to the preparation of low uniform code, only a very small portion of all the goods, other categories of low code maintenance by the enterprises themselves. Because of the classification and understanding of different templates, in fact, a company formed a code, which is building a centralized ERP, e-procurement, supplier prices and centralized management, statistics, inventory reserves, information sharing is required for procurement suited.
(2) material classification is not uniform and unreasonable. One, the product classification and material classification is not uniform, which is both a product and also the procurement of materials, the code is not uniform as ERP, e-commerce information system to run an obstacle. Second, engineering materials, materials classification and classification of non-uniform, is not conducive to general contracting construction material procurement unified management, systems engineering design can not be achieved and ERP systems, and material procurement e-business system data exchange and information sharing. Third, part of the material classification is unreasonable, in part apparent division between classes is not conducive to a clear classification, and current applications of information incompatible with the requirements.
(3) of the material has been behind the technological progress and economic development. One out and new materials technology, the use of new products. Example, need to remove the boiling steel, composite materials necessary to increase; second part of the classification to reflect the characteristics of the planned economy at that time, and now need to be adjusted.
(4) of the rules of perfect template material can not be scientifically and reasonably accurate description of the goods. Description of existing materials template is divided into a unified structure of three sections, namely, the name describes materials and specifications, the material (or standard), no detailed definition of the natural properties of each material.
(5) there is no uniform code prepared low. Headquarters in a unified low code only 10 categories, and the remaining 46 categories of low code prepared by the enterprises themselves according to the template. From a business perspective is essentially a thing one yard, but Sinopec general, the formation of large quantities of supplies of a material fact, multi-code, on a number of application integration and data exchange system a serious obstacle to the development of information technology do not meet requirements, is not conducive to master the material supply management as a whole.
Second, project content
Coding implementation by the leadership attaches great importance to the China Petrochemical, coding materials and equipment by the Ministry of the Working Group as head of development projects, Information Systems Management Department as deputy director, production management, finance, science and technology development department , oil field exploration and development business unit, division refining, chemicals division, division of oil sales, construction management department, petrochemical PCCW and Beijing as members of the three-dimensional company, jointly determine the implementation of the program coding.
June 2005, officially approved coding system, research evaluation and project completion approval; in July 2005 to 10 months to complete coding system development; in November 2006 completed a 1.8 million basic coding of the preparation, revision and Initial processing of the initial conditions with enterprise data conversion; next prepared by the company in 2007 to complete ERP system, coding conversion work, the establishment of a unified coding system of Sinopec.
After business, suppliers and other experts through discussions, re-established coding revise and perfect the program, to determine the overall thinking and working principle, meaning no water 8-bit code as the coding of the main code, to facilitate action to retain the original 16 yards as a secondary code. While redefining the rules of all the categories described in the formulation of the relevant material description template.
Coding rules and coding according to the general requirements, three-dimensional world by Beijing has completed coding management system development and testing. The coding and business management system is based coding reporting, generation, inquiry, maintenance of the working platform, able to describe the rules for all categories and all the data finished loading into the system, so that automatic identification of materials described by standard , configuration coding, and coding to achieve a comprehensive inquiry, classification query, fuzzy query and other convenient features, for the coding of the establishment, consolidation, auditing provides a great convenience, efficiency is greatly increased.
Achieved through the system's focus on coding and web review amendments, including the template description, material items description, be scientific, accurate, reasonable and practical.
Third, the project using the results
The implementation of the system has the following significant features:
1. To achieve materials, construction materials, petrochemical products and a unified description and coding
Petrochemical products, purchasing materials in the classification, description template to achieve the complete reunification of the template defined in accordance with the requirements for the preparation of the low level code.
Materials involved in engineering design into 56 categories classification, materials described in the materials described in a uniform template. Consider the special nature of engineering design, allowing a unified code is added after the preparation of the low correlation design information, and correspond with the coding.
2. In accordance with the first principle of the natural attributes to classify and describe the material, enhanced coding of scientific, rational and practical.
Classification has been adjusted and revised classification of the previous cross, repeat, does not adapt with the current management problems have been effectively alleviated.
Description of the template material to break in a simple three-paragraph description of the rules of each categories of materials to the template of natural attribute definitions, description of materials is more scientific and standard. Do not follow the standard reporting template material description, the system does not accept, effective solution to the artificial and arbitrary description of irregularities.
Able to adapt to semi-finished products, waste defective management, import special parts, packaging materials procurement and services piecemeal procurement of a new class of demand.
3. A unified budget low key, from an overall perspective of China's Sinopec to achieve a material one yard.
Low code unified, centralized management, data segmentation, real-time sharing of the problem can not be solved. China's petrochemical systems integration, information sharing has laid an important foundation. Use coding management system reporting, publishing, operation more efficient and fast. The new coding system used for registration system (product part of the use of audit system) approach to maintenance, enterprise reporting system, the system in accordance with the description of the template automatically check the correctness of description, check weight, release of new code, between mouse clicks to complete, Artificial maintenance of the past do not change the specification, the drawbacks of a long time, greatly enhance the accuracy and efficiency. Coding to achieve centralized management, unified classification, unified description of the template preparation, unified description of the preparation of concrete materials, China's petrochemical production and fully meet the requirements of management, ERP system to fully adapt to the main line to run the information system requirements, and a strong science , practicality and applicability, to enhance the level of China's petrochemical production and management, strengthen the management of material supply, and promote information technology laid an important foundation.
