1. Logistics terminology standard
Logistics terms often have different meanings because of different countries, regions, industries and personnel, and misunderstandings and mistakes may occur when transmitting logistics information. Therefore, it is necessary to unify logistics terminology and provide a standardized language for logistics information exchange, which is the basic work of logistics information standardization. In August, 20001year, China Federation of Logistics and Purchasing and China Logistics Society promulgated and implemented the national standard "Logistics Terminology", and collected and determined 145 terms and their definitions which have basically matured in the current logistics field, thus creating a good start for the standardization of logistics information in China.
2. Logistics information classification coding standard
Logistics information classification and coding standard is a professional field and branch of logistics information standardization. Its core is to rationalize and unify a large number of logistics information, express it in code, and form a standard information classification code, which is convenient for people to search and query information manually or by computer. This is the premise of the normal operation of logistics information system. The classification and coding standard of logistics information consists of three levels, the first level is category, the second level is category, and the third level is project. The United States began to study the problem of standard information classification and coding from 1945, officially started the standardization of material coding from 1952, and completed the national material classification and coding in six years. China started to formulate relevant standards from 1979, and now dozens of information classification and coding standards have been issued, especially the index system classification and coding of cadre personnel management information system. Basically, the data elements and classification codes are complete, and a relatively complete coding system has been constructed, while the logistics information classification coding standard is still under construction and formulation.
3. Logistics information collection standards
Unify the collection methods, means and formats of logistics information, for example, in the barcode standard, specify the types and application scope of barcodes, the arrangement rules, start symbols, end symbols, data symbols, verification symbols and blank areas of each barcode, and unify the reading and processing program standards of barcodes; In the radio frequency identification (RFID) electronic tag standard, the information storage format, overall size, power supply mode, working frequency, reading mode, effective distance and signal modulation mode of electronic tags are uniformly specified. In the technical standard of Global Positioning System (GPS), coverage, reliability, data content, accuracy and universality are stipulated.
4. Logistics information transmission and exchange standards
Unified provisions of logistics information communication protocol, transmission mode, transmission speed, data format, security, exchange procedures, etc. For example, in the electronic data interchange (EDI) standard, EAN International (EAN) formulated the data format and message standard, and based on the UN/EDIFACT standard, developed the EANCOM standard in the circulation field; Based on the interconnection of ISO-OSI open systems, communication standards adopt different standards for different objects, such as UCS (Unified Communication Standard) for groceries. For most businessmen, VICS (Voluntary Inter-industry Standards Committee) and WINS (Warehouse Information Network Standard) are adopted, while TDCC (Transport Data Coordination Committee) is adopted by transport operators and AIAG (Automobile Industry Activity Group) is adopted by the automobile industry. The communication modes include point-to-point (PTP), value-added network (VAN) and information processing system (MHS). There are many EDI applications in China, such as the standard data element GB/T15191997, and the code table GB/T16833-1.
5. Logistics information recording and storage standards
Specify the recording, storage and retrieval methods of logistics information. For example, formulate unified standards such as storage medium, storage form, storage process, database type, database structure, indexing method, compression method, query processing, data definition language, data query language, data operation language, integrity constraint, etc. At present, the relevant standards are ISO 857 1-2: 1988 (published by the International Organization for Standardization, information processing system-open system interconnection file transfer, access and management Part 2: definition of virtual volume storage), and ISO 3788: 1976 (published by the International Organization for Standardization) has become China's national standard.
6. Logistics information system development standards
Establish standards or specifications of logistics information system, such as process standards (methods, technologies, measurements, etc.), such as requirements analysis, design, implementation, testing, manufacturing, installation and inspection, operation and maintenance until the software is retired (replaced by new software). ), product standards (requirements, design, components, descriptions, plans, reports, etc.). ) and professional standards (occupation, ethics, etc. At present, the relevant standards include ISO 5807 (issued by the International Organization for Standardization, which has now become China's national standard GB/T 1526- 1989), Information Processing-Document Symbols and Conventions of Data Flowchart, Program Flowchart, System Flowchart, Program Network Diagram and System Resource Diagram, and ISO 863/KLOC. Now it has become China's national standard GB/T 13502- 1992) Information Processing-Program Structure and Its Representation Protocol ISO/IEC10165-1:1993.
7. Logistics information security standards
User authentication, encryption and decryption, firewall technology, data backup, port setting, logging, virus prevention and a series of technical standards. , formulated to prevent or eliminate illegal access (including illegal access by illegal users and illegal access by legal users) to logistics information systems, At present, the relevant standards in China are GB/T18019-1999 "Technical Requirements for Information Technology-Filtering Firewall" and GB/T 18020- 1999 "Technical Requirements for Information Technology-Application Firewall".
8. Logistics information equipment standards
General standards and technical specifications for a series of logistics information equipment such as switches, hubs, routers, servers, computers, uninterruptible power supplies, bar code printers, bar code scanners, storage, data terminals, etc. Existing standards such as GB/T 15533- 1995 Information Processing System-Small Computer System Interface, GB/T14715-1993 Information Technology-Uninterruptible Power Supply for Equipment, GB 9254-.
9. Evaluation criteria of logistics information system
The unified regulations and requirements for product testing and evaluation of logistics information systems are as follows: existing standards such as GB/T 17544- 1998 "Information Technology-Software Package Quality Requirements and Testing" and GB/T17917-1999 ". GB 13423- 1992 Evaluation Standard of Software for Industrial Control, GB/T 16260- 1996 Evaluation of Quality Characteristics of Information Technology Software Products and Its Usage Guide, etc.
10. Logistics information system development and management standards
Unified standards for a series of management work such as quality control, process management, document management and software maintenance in the development of logistics information systems, such as GB/T 16680- 1996 software document management guide and GB/T 12505- 1990 computer software configuration management plan specification.
