Description

METHOD AND APPARATUS FOR PROVIDING A GARMENT MANUFACTURING PLATFORM

The present invention relates to a method and an apparatus for providing a clothing manufacturing platform, and more particularly, to a production factory that determines a production quantity for clothing products requested by a customer, and entrusts production of clothing products based on the determined production quantity It relates to a method and apparatus for determining

Food, clothing, and shelter is an expression that refers to the three basic elements that people need to live. In modern times, clothing (clothing) among food, clothing and shelter is not only a basic element of life, but also plays a role as a display tool to express one's individuality or value. These garments have changed along with the changes of the times, and not only their external design but also the design methods, tools, manufacturing methods, and sales methods have changed along with the changes of the times. For example, recently, clothes are sold through the Internet, TV home shopping, etc. in addition to being displayed and sold in a conventional shopping mall.

As mentioned above, as the clothing industry grows according to the changes of the times, various problems may occur. In general, in the apparel industry, several operators, such as design companies, fabric companies, dyeing companies, label companies, and producers, are intricately connected, and most are done manually. Therefore, if it takes a lot of time to manufacture a product or if a defect occurs at any one of the subcontractors, it may be difficult to rectify the responsibility because the location of responsibility is unclear. In addition, compared to other industries, the apparel industry is more sensitive to fashion and difficult to predict demand, so it maintains a high inventory ratio compared to other manufacturing fields. For example, other manufacturing sectors maintain an inventory ratio of 10-13%, while the apparel industry has more than 20% of inventory, where clothing is produced and not sold, which is twice that of other manufacturing sectors.

In addition, in the case of the apparel industry with a high inventory ratio as described above, there is a difficulty in determining the production quantity in the process of manufacturing apparel products, and additional efforts are required to handle unexpectedly occurring inventory. For example, clothing products that remain in inventory without being sold through department stores, agencies, and large marts, which are primary distribution markets, are sold through secondary distribution markets such as outlets, home shopping and Internet shopping, and also sold through secondary distribution markets. The remaining clothing items are donated to welfare organizations, exported to third countries, or undergo other processing such as incineration. As above, when the supply of clothing products exceeds the demand, inventory products are generated, and unnecessary time and costs are incurred to process them.

An object of the present invention for solving the above problems is to provide a method and an apparatus for determining a production quantity for a clothing product requested by a customer.
