What are the applications of electronic information technology in garment and textile industry?

Electronic information technology is the fastest growing industry in recent years, and the development of all other industries is inseparable from the application of electronic information technology in this industry. At present, electronic information technology is the leader of all industries, and its application in textile industry is mainly in three aspects: textile enterprise management information system, textile professional CAD system and textile production process automation. 1. textile enterprise management information system

Enterprise management information system is a system that provides assistant management and decision-making services for managers by using computer technology, network communication technology and management decision-making technology. Adopting advanced, applicable and effective enterprise management information system and applying it to all links and levels of enterprise management can improve the operating environment, reduce operating costs and enhance the competitiveness of enterprises; In the enterprise's supply chain, the smoothness of logistics, capital flow and information flow can be improved, so that enterprises can respond to the rapidly changing and unpredictable market intelligently and quickly, and meet the needs of users accurately and effectively; In addition, it can also make all kinds of business data of enterprises more accurate, timely, comprehensive and detailed. Due to the further processing of all kinds of information, the decision-making basis of enterprise leaders' production and operation is more sufficient and scientific, and they can better grasp business opportunities and create more development opportunities; It is conducive to the scientific, rational, institutionalized and standardized management of enterprises, so that the management level of enterprises can reach a new level and lay the foundation for the sustained, healthy and stable development of enterprises.

At present, there are many kinds of enterprise management information system software, such as manufacturing resource planning (MRPI), enterprise resource planning (ERP), intelligent resource planning (IRP), product data management (PDM), electronic document management (EDM), intelligent output management (IDM) and so on. Here is a brief introduction to the most widely used and hottest ERP system in China.

ERP system is an enterprise management software system which mainly manages the material resources, capital resources and information resources of manufacturing industry. Its core idea is to rationally allocate all aspects of resources (manpower, capital, information, materials, equipment, time, technology, etc.). ) in order to give full play to its efficiency, so that enterprises can give full play to their energy in the fierce market competition and obtain the best economic benefits.

ERP system is developed from Material Requirement Planning (MRP) system and Manufacturing Resource Planning (MRP Ⅱ) system. With the development of computer technology in 1960s, MRP theory was put forward in western enterprise management. In 1980s, with the development of computer network technology and information sharing within enterprises, the subsystem of MRP formed an integrated system integrating procurement, inventory, production, sales and finance, and developed into. In this system, production planning (MPS) and material requirements planning (MRP) are its core functions. It includes production, supply and marketing and property management of enterprises. With the help of composition data, process data and equipment status data of products and parts, the market demand for products is transformed into the demand for raw materials and parts for processing and purchasing, and the master production plan, material demand plan, capacity balance plan, purchasing and inventory control, production cost accounting and supply chain planning control are completed by computers, so as to realize the optimized scientific management of the complex production process of enterprises in a certain sense and ensure the market of enterprises from the management point of view. But it is limited to the management of internal logistics, capital flow and information flow. In the 1990s, the wave of world economic integration swept the world, and people realized that it was impossible to effectively participate in market competition only by the resources in an enterprise. All relevant links in the business process, such as suppliers, manufacturing plants, distribution networks and customers, must be brought into a tight supply chain, so as to arrange the production, supply and sales activities of enterprises more effectively, meet the needs of enterprises to make use of all market resources to carry out production and operation quickly and efficiently, and further improve efficiency and market competitiveness. Therefore, it has developed into an enterprise resource planning (ERP) system. ERP emphasizes the management of supply chain. In addition to the manufacturing, finance and sales functions of traditional MRP system, it also adds the functions of distribution management, human resource management, transportation management, warehouse management, quality management, equipment management and decision support. It is an advanced enterprise management concept, which fully distributes and balances all aspects of enterprise resources, provides various solutions for enterprises, is customer-oriented, and connects enterprises and markets. ERP system is a modern enterprise management tool, and 80% of the top 500 enterprises in the world are using ERP system. Foreign MRP ⅱ and ERP management software has a history of nearly 20 years in China, but there are many problems in directly using foreign MRP ⅱ and ERP software because our national conditions are different from those in the West. Since 1998, dozens of domestic financial software companies, such as Kingdee, Netizen, Inspur Guoqiang, Anyi, Hengyuan, Yinhe Tektronix, etc. , has begun to March into integrated enterprise management software. At present, a management software system suitable for the national conditions has been developed. In particular, Beijing Yinhe Tektronix Information Co., Ltd. launched a special textile enterprise? Quot galaxy ERP2000 system ". It includes 13 subsystems, namely, marketing management subsystem, comprehensive planning subsystem, inventory management subsystem, supply management subsystem, cost management subsystem, workshop management subsystem, product data management subsystem, equipment management subsystem, quality management subsystem, financial subsystem, personnel organization subsystem, office automation subsystem and decision support subsystem.

2. Textile CAD system

Computer-aided design (CAD) is a theory and method that uses the powerful computing function and efficient graphics processing ability of computer to assist product design and analysis. Textile CAD has five main functions:

⑴ Computer simulation of yarn: It mainly includes the simulation of ordinary yarn, mixed color yarn and decorative yarn. The number of strands, twist, blending ratio and color of the yarn can be adjusted at will. It can also simulate yarn hairiness.

⑵ Computer Aided Design of Woven Fabric: There are mainly plain weave design, yarn-dyed weave design and jacquard weave design. Fabric weave design can carry out various weave designs. Such as basic organization, change organization, joint organization, complex organization and so on. Some can also design three-dimensional fabrics; After the weave design of colored yarn fabric is completed, the simulated images of fabric appearance and yarn, weave and fabric structure can be given, which shows the appearance effect of real fabric very realistically. After the organization design is completed, the computer can automatically generate the comprehensive map, chessboard map and reed map according to the organization chart.

⑶ Computer aided design of knitted fabrics: mainly including jacquard pattern design and structure design. Patterns can be drawn in three ways: symbols, colors or icons. At the same time, the computer displays the rhyme of the prompt, which makes the environment better. What? Muscle? What are you talking about? A variety of basic flower structures, such as twisted flowers, A Lang flowers, perforations, raised strips, etc.

⑷ Textile printing design: mainly the pattern design of printed fabrics. Generally, there are three methods: freehand drawing. The computer provides a series of tools such as pens, lines, colors, copying, cutting, pasting, flipping, zooming in and out. , are created by designers at will; In addition, the system provides some basic geometric figures and basic patterns, which can be selected directly or in combination; Finally, users can input their own patterns through scanning.

⑸ Clothing computer-aided design: there are mainly two-dimensional clothing design and three-dimensional clothing design. It includes style design, structure design and process design, and some have automatic measuring system and cutting system. In style design, fashion illustrations, style drawings and effect drawings are drawn by various tools provided by the system. In addition, the system also has a style library. The designed clothing can show the effect of clothing "wearing" on human body through simulation.

Textile-specific CAD system has been studied in China for more than ten years, and many useful CAD systems have been developed, but most of them are based on DOS. At present, it is transferring to Windows95/98/NT platform. Foreign countries are much more advanced in the field of textile CAD than domestic ones, and now they are developing into the function of integrating textile design and clothing design. 3.
