Chapter 1 Demand Analysis
With the rapid growth of corporate brands and the rapidly changing market, the original factory packaging and logistics links are clearly unable to keep up with the pace of enterprise development.
According to statistics, the number of complaints about shipment errors is high, and the original box complaints are as high as 40%.
1.1.2 The supply cycle is too long
Changes in the internal and external environment, the problem of too long supply cycle has become increasingly prominent.
The current supply cycle has been hovering between 60 days and 90 days, while the implementation of the QR strategy by similar foreign companies has achieved a replenishment period of less than 2 weeks. Spain's ZAYA can be delivered to the store for a minimum of 3 days.
Analysis and solution based on RFID garment industry picking and packing system
1.2 Demand Analysis
Basic description of demand: The existing packaging process is difficult to ensure the accuracy of the packing, the problem of the original box is relatively short, and it is unable to adapt to the new business model of the PPT project. The fourth floor of the Foshan plant is planned to be used as a test base for the PPT project. The processes including cutting, sewing, finishing, and packaging are all planned and designed in accordance with the requirements of the PPT project. RFID technology is applied to help achieve production for 7 days. , the goal of logistics for 7 days. In view of cost and schedule factors, the automated packaging line is not ready for this period. Proposed requirements for interfacing with existing production management systems. The pilot plant is scheduled to start in November 2007.
1.2.1 System objectives
Using RFID technology to solve the problem of short and inefficient original boxes in the current product line from the factory to the factory, to achieve accurate and rapid sorting and packaging of clothing products, in order to meet the goal of shortening the delivery period to 14 days. .
1.2.2 Precision packing
In view of the bad packaging effect in the past, the company attaches great importance to the effect of packing. According to our understanding, the following points are summarized:
1. The quantity should be accurate;
2, easy to operate;
3, does not require a high degree of automation;
4. It is easy to promote and use in most existing factories;
5. The lowest cost;
Analysis: Comparing the current multi-packing schemes, in order to meet the above-mentioned packing requirements, the best is the picking and packing system solution using RFID label technology. In addition to RFID tags, bar codes are one of the most used identification technologies. The advantage of bar code technology is that the price is relatively cheap, but it does not have the ability to be recognized by long distance and multi-target at the same time. In addition, it cannot identify product items and can only identify product categories.
On the contrary, RFID tags have the advantages of small size, large capacity, long life, reusable, fast reading and writing, non-visual recognition, mobile recognition, multi-target recognition, etc. The ID code is unique in the world and thus becomes automatic. An emerging force in the field of identification is a leader in the field of automatic identification for the foreseeable future.
By using RFID tag identity uniqueness, by attaching, embedding or embedding an RFID tag on each piece of clothing, it is possible to completely solve the problem of unrecognizable clothing, tracking problems, and accurately boxing when packing.
1.2.3 Shorten the lead time
Shortening the lead time is one of the most important requirements for apparel companies. The requirements for apparel companies to shorten the lead time are as follows:
1. The supply cycle is shortened to about 2 weeks;
2. The production time during replenishment shall not exceed 7 days, and the logistics time shall not exceed 7 days;
Analysis: In order to shorten the delivery cycle requirements, it is necessary to optimize the problems in production, packaging, inventory, and transportation. This program mainly addresses the problems that need to be faced in packaging and inventory.
The most popular method in the world is to use the rapid response QR technology, JIT timely production method, EOS electronic ordering system based on EDI technology and OPS order processing system to achieve the goal of shortening the supply cycle, and RFID tag technology is to shorten the supply. An indispensable technical means of the cargo cycle.
1.2.4 Inventory Management
Inventory management is a very important part of the apparel industry. Establishing a rapid response QR inventory management system is the key to achieving fast replenishment.
The inventory management of finished goods of garment enterprises mainly includes the identification and positioning of finished products, packaging, stacking, storage and storage, and inventory. After the finished product is offline, it is uniquely identified by RFID tags, and information is collected on the nodes such as packing, loading position and upper tray, so as to realize the effective and accurate positioning of the finished products in the inventory management, realizing the real-time dynamic inventory of the finished products, and establishing Quickly respond to QR's inventory management system and eliminate possible barriers to inventory management.
