A successful business often have to know what kind of products customers need, and to provide low-cost, high-quality, high-performance products. They welcome the special requirements of customers, as an opportunity different from their competitors. In recent years, due to increased competition, to the 90's, business-to-customer service has become an advantage. Enterprises in order to win in the competition, we must change the focus of its trade cycle. The current trade cycle should be seen as being driven by the customer - "market as a leader" and stressed the establishment of business partnerships in the trade cycle. The most important feature of a successful business is the degree to which it is driven by customers, by providing quality products and services, on-time delivery, low cost and high quality to win the customer's total satisfaction.
In order to achieve effective customer service, enterprises must have the ability to quickly respond to their customers' special business needs. In order to reduce inventory and improve order fulfillment rate, to select a shipping channel is particularly important. As a result of geographical factors such as the impact of direct delivery from the enterprise suppliers to customers is a common business approach. In addition, we must also pay attention to optimize the inventory, attention to equipment. A variety of resources and space utilization, so as to achieve some of the logistics operations management. The actual layout of the warehouse must be optimized. So that it and the operator, material receiving, through the main stock to pick up and send the process and type of match. The correct definition of the geographical distribution of warehouses will help reduce the movement of goods, improve storage efficiency, reduce costs and save money. The geographical layout of the warehouse can be defined as two-dimensional, three-dimensional, freestyle or modular. For example, the main warehouse is generally defined as two-dimensional: channels, shelves, cargo layer. The cargo address is available in 2D. Storage locations can be defined by storage capacity, pallet type, storage container, shelf type, and special purpose. The type of cargo handling can be a large number of storage, temporary storage, such as temporary returns. The batch number control of the product is a key storage processing item. Products should have batch number, in order to track the quality of the expired material control to ensure delivery to the customer is in line with the requirements of the quality of legislation products. Visible, today's warehouse operations and inventory control operations have been very diverse. Complex, rely on artificial to memory to deal with has been very difficult. If you can not guarantee the correct purchase, acceptance, quality assurance and delivery, will lead to a waste of time, resulting in inventory, delayed delivery, increase costs, resulting in the loss of opportunities for customer service. Using bar code technology. And with information processing technology, to ensure the accuracy of inventory, to ensure the necessary level of inventory and warehouse material movement. Consistent with the purchase of goods shipped to ensure optimal product inflow, storage and out of the warehouse.
The most common technical topic in warehousing today is bar coding, along with data storage, transmission, intelligent software, computer platforms, and communications networks. Regardless of where the logistics flow, we can automatically record the flow of logistics, bar code technology and information processing technology combined to help us rationally, and some use of warehouse space, the fastest, most accurate, the lowest cost way for customers For the best service.
Here are two examples: one is economical, easy to implement the warehouse management program; the other is the three-dimensional warehouse management program.
The first scenario can be a warehouse for each of the goods, each location to make a written report, and periodic periodic inventory of the reservoir area. This program on the retail trade of goods library, the hospital's drug library is very practical.
In the design of specific programs should be selected according to different requirements of different software and bar code equipment. For example,
1. Does the customer require the barcode scanner to communicate with the host computer continuously?
2. Whether the data can be batch?
3. What is the amount of data collected in one day?
4. Is continuous scan or scheduled scan?
5. How long will the results of data processing be reported once, every hour, every day, or every month to send inventory data to the database? How is the physical location in the warehouse identified?
6. Data item barcode label when and where the use of who, after the label from the library if there are other users need to scan and so on.
For the system is this operation: the warehouse staff with a handheld bar code terminal to scan the cargo space, sweep into the cargo number, the goods on the corresponding item number (such as part number) to scan and type the item Number, and then on the second cargo space and its goods on the scan, so repeat the above steps, until the warehouse all the goods point clear. And then the bar code data collected in the terminal through the communication interface to the PC.
All the software used in the system is divided into two parts: one part resides in the bar code terminal, the other part is on the PC (or other minicomputer, host). Bar code terminal software to complete the data acquisition function, relatively simple, the average user can own programming. The PC software should include the database system and warehouse management software.
The completion of the data acquisition function of the bar code terminal requirements are not high, do not need very complex functions (such as ZZ9801 machine). There is a 4-line xl6-character display to display the collected data and the program menu; a keyboard input number of items; a certain capacity of data memory (256KB ~ 512KB or larger capacity); bar code scanning part can use pen (Such as HP305 light pen), CCD type (such as Cipher Lar l021 CCD), laser gun type (usually should use laser gun, because the pen and CCD scanners are contact scanning, can not adapt to warehouse operations); -232 serial port as a two-way communication with the PC interface. Terminal in the program downloaded by the PC, and the terminal to the collected data is uploaded to the PC to go.
When the warehouse operation increases, the number of bar code terminals can be increased. But the PC does not have to increase, of course, the configuration of the PC to be appropriate, such as 486 or 586 machines, 500 megabytes or more hard drives.
In addition, the system need to configure the bar code printer, in order to print a variety of labels: goods, shelves with the label; item identification with the label, and indicate the batch number, quantity. Of course, first determine how these items are identified, each item, each unit, each box ... ... labeled, or what other programs. In addition, the warehouse staff to identify, to facilitate management. How to design the bar code, label format, etc. are designed to do the program stage to be completed.
This system has the advantage of low cost, flexible system. For those who are not familiar with the bar code technology users can start here.
Another example is the management system of a main warehouse. The main warehouse used by the construction area of 3,200 square meters, 5.5 meters high. There are five roadway, including four double-extension roadway, a single stretch roadway; cargo size of about 1.5x1.5x1.1 meters, a total of 3000, up to 7 layers; container size of1.2 X0.7x0.7 m , Gross weight 215 kg; tray size of 1.25x1.47x0.08 meters, each tray on the two boxes. Storage capacity of 120 per hour cargo space; warehousing 80 cargo spaces / hour, the library 40 per hour cargo space.
Warehouse operations: the trailer will be unloaded from the container after the container, and then trailer every two boxes according to the specified location on the storage platform empty tray. Goods identified by the bar code identification system tray number, the computer system will control the conveyor system tray will be sent to the designated storage of goods on the roadway, and then by the roadway carts will be on the tray to the designated cargo space. Outbound operation: according to the warehouse to enter data into the warehouse management system, according to the principles of the library (such as FIFO) issued a library operation instructions, the roadway vehicles will be specified by the goods on the goods to the location Library goods on the grid, and then transported to the designated delivery system to the library platform.
The system uses a fixed bar code reader (such as TLMS-3500 RV) to automatically identify the tray label on the inbound / outbound delivery system and upload the signal to the computer system in real time. After confirmation, the system directs the conveyor line to the tray Of the container into / out of the corresponding roadway and location.
System to computer monitoring machine as the center, through the RS-232 port directly connected to the transmission line control system. Through an 8-port communication manager to connect the library bar code reader, and directly with the programmable controller serial port module connected through a 16-port communication manager to connect storage and bar code bar code reader, and through the RS-232 port directly and Monitor connected.
Using this system can improve the accuracy of the goods out of storage / storage, to ensure high-quality products, but also can change the existing system of manual handling labor intensity. The work efficiency is low.
Bar code technology as a link between the various stages of product life information together, can track the product from production to sales of the whole process, so that enterprises in the fierce competition in the market in a favorable position. And bar code can guarantee the accuracy of the data, the use of bar code equipment is convenient and fast, automatic identification technology and the keyboard can not be compared efficiency.
Japan's Sharp Electronics four years to adopt a bar code warehouse management system, the number of warehouse operations increased by two digits, the number of people has not increased, and the inventory accuracy of 100 percent; delivery and purchase operations of the rate dropped to zero, and some labor The amount of work is also compressed. In the past paper-based operations, there were about 200 errors per month in terms of shipments and warehousing, and it often took several months to track these differences after the error, so as not to expand its impact. Now every goods out of storage, the operator immediately bar code on the goods with a hand-held CCD laser gun reading, through the data collector to the data in a timely manner into the computer; and some bar code reader is installed directly Lifts, to avoid the error occurred.
In modern society, the market economy determines the status of the warehouse is not a lack or not, but the market economy and the market between the modern enterprise of the important transfer of goods and storage of the necessary infrastructure. Warehouse management to achieve modern management tools, bar code technology is to ensure the optimization of warehouse operations, make full use of warehouse space, fast and convenient for customers to provide quality services, foreign exchange appreciation of the priority means.
