1 Introduction
Competition in the garment processing industry is becoming more and more fierce. To be invincible in the market competition, enterprises in the garment industry must continuously improve production efficiency and shorten the capital turnover time. According to market research and analysis, through informatization of the entire clothing industry, production efficiency can be greatly improved and capital turnover time can be shortened. At present, most of the clothing industry is all manual work, without any informatization, resulting in poor information feedback. When a problem occurs, it cannot be discovered and dealt with in time, which leads to a lack of work in many links. At the same time, the situation of product sales can not be grasped in time, leading to the out-of-stock of the best-selling products and the under-sales products, which also reduces the profit.
If all aspects of product design, raw material procurement, order placement, order execution, product processing, quality inspection, warehousing, logistics transportation, distribution, and product sales are all informatized, it will provide users with real-time dynamic tracking and query throughout the process; realize processing information and systems Monitoring and management of operation status and business operation quality, while providing real, effective, and timely management and decision support information for managers at all levels, providing support for the rapid development of the business, will be able to solve all problems, and thus reduce costs and increase profits. And competitiveness.
