Introduction of Intelligent Warehouse Management System
The process of precision warehouse generally includes several processes, such as receiving goods, putting on shelves, picking up goods, replenishing goods, delivering goods, and counting. Here from the six processes to illustrate the specific implementation process of RFID warehouse management system:

data preparation

–All delivered goods need to be imported into WMS by EDI, Excel or manual input in advance.

All customer orders need to be entered into WMS by EDI, Excel or manual input in advance.

In order to support the logistics center to use RFID or electronic tags, transportation and sorting lines and other modern logistics equipment, it is necessary to carry out bar code planning and design in the following links.

-Barcodes of all operating units in the warehouse, including pallets and turnover boxes. Stick the fixed serial number label directly on the operation container.

-Barcode of the inventory location in the warehouse. According to the order of warehouse-line-location-floor, the position of goods is coded and labeled with bar code.

-Barcodes of operating documents and operating instructions.

—Print the barcode of the document number and product code on the receipt document to assist the receiving personnel to receive goods by RFID.

—By printing the picking label, the picker is guided to get the picking task, which is convenient for identifying the goods on the conveying line.

Labels for different purposes

Receive goods

–In the receiving area, RFID is used to code pallets (if necessary) and receive goods. It is required that all goods stacked in the receiving area must have a unique pallet number, and the pallet number is attached to the pallet in the form of bar code label.

–If the sales order has not been delivered, the system instructs to send the goods to the temporary storage area.

record

–The system specifies a corresponding delivery area for each order according to the vehicle information and quantity information of each order.

–The system automatically matches the received goods with the sales order, and generates a distribution task for each pallet of goods in the receiving area.

The tallyman scans the label of each pallet in the receiving area and carries the goods to the temporary storage area or waiting area of the corresponding order according to the instructions. If the goods need to be delivered to multiple orders, you need to confirm each delivery area and quantity separately. Use a new pallet when distributing goods and confirm the new pallet number.

–When goods need to be distributed from the temporary storage area, RFID will instruct tally personnel to pick up the goods from the temporary storage area and then distribute the goods.

review

–After the order is distributed, the reviewer will be prompted to recheck the product and quantity.

pay

–Scan each pallet in the area to be delivered in turn and confirm the car number to be delivered.

Every link of warehouse management

Six links of warehouse management:

Receive goods

See atlas

Specific receiving and warehousing operations:

(1) Receiving inspection

Key inspection:

Whether the delivery note is consistent with the purchase order; Whether the goods are consistent with the delivery note; If not, refuse to receive.

(2) Making and pasting labels

The specific method is as follows: adopt the selected material coding scheme to code the incoming materials; Making commodity labels: Write coded information into electronic labels, print paper labels at the same time (convenient for manual check), and then glue the paper labels and electronic labels together to become commodity labels. Fixing labels on inventory: Considering the high cost of labels at present, in order to facilitate the recycling of electronic labels, labels are generally fixed on articles by hanging. If it is not recycled, it can be pasted and fixed.

(3) The site computer automatically allocates the location, and gradually downloads the location number and the item number corresponding to each operation to the wireless data terminal (handheld terminal or forklift terminal);

(4) The operator delivers the goods to the designated warehouse, and sends the goods to the warehouse after checking that the location is correct (if necessary, modify the goods number and quantity information recorded in the warehouse label);

(5) The wireless data terminal sends the warehousing information to the on-site computer and updates the inventory database in time.

Shelf (storage)

Barcode is attached to each box of goods, and passive labels are installed on the boxes after packing. Goods boxes with passive labels are stacked according to the storage location read by PDA in the hands of staff, and an active electronic label is installed on each tray. Put the goods on each pallet on the corresponding shelves respectively;

See atlas

Tray signal

Look for locations according to different reservoir areas; Assign different locations according to different packages (trays, boxes, pieces); According to the attributes of products (normal products and damaged products), shelf distribution is carried out; Volume limit, weight limit, quantity limit, length, width and height limit; Mixed batch number and mixed product limit; Merge products with the same batch number; Adjacent selection of similar products; Different order types can be placed in different locations, such as normal purchase orders and return orders.

Allocate shelves according to ABC activities of products.

Pickup trolley

1: The trolley downloads batch orders at any terminal of WMS system.

2. According to the optimal path, the system automatically instructs the car to sort the goods according to SKU;

3. Confirm the pick-up location information, and the trolley will automatically prompt the quantity of "pick up while dividing" according to the lighting system, and then press the light to confirm after the goods are distributed;

4. The trolley automatically receives the instructions from the system and guides the operator to pick up the next position in real time until all the batch orders are completed.

Pick-up location management mode

Fixed picking

–The minimum inventory and the maximum inventory need to be set at the pick-up location. When the inventory balance falls below the lower limit, an alarm will be issued to remind you that replenishment is needed.

–Sometimes, in order to meet special delivery requirements, a container delivery warehouse or a parts delivery warehouse can be set up separately. When the picking inventory balance is lower than the lower limit, it is required to replenish from the storage area, and when the picking inventory balance of parts is lower than the lower limit, it is required to replenish from the picking warehouse or storage area.

The setting of picking position is based on the analysis of inventory flow direction, which will improve access efficiency and sacrifice some storage space.

Dynamic picking

–Due to seasonal changes in product sales, ABC activities of products will change periodically.

–The method of fixing the pick-up location will greatly increase the workload of the system administrator. FLUX WMS supports the setting of dynamic picking positions, and dynamically allocates picking positions for products according to ABC dynamics of products.

–Set the whole container delivery area and unpacking delivery area in the warehouse.

Different picking operation modes

Picking tasks can be assigned in three ways.

–-RFID automatic acquisition

–Print delivery labels

–Print the list of picking tasks.

Different delivery methods

–Order Picking

–waveform pickup

Pick first and then broadcast separately

Supplement (moving goods)

When the warehouse needs to be moved, the computing system sends an instruction to the PDA in the operator's hand. After seeing the instruction, the operator locates the corresponding goods and the corresponding quantity, moves the goods to the corresponding target warehouse, modifies the information of the corresponding label after completion, and sends the corresponding data back to the system computer;

See atlas

The system supports two different replenishment modes.

–Regular replenishment: the regular replenishment mode of the logistics center.

–Order-driven replenishment: in an emergency, the replenishment task is triggered according to the order demand.

Set the minimum inventory, maximum inventory and minimum replenishment unit for picking locations. When the inventory at the picking point is lower than the minimum inventory, replenishment is generated.

work

Replenishment tasks can be obtained in the following three ways.

–-RFID direct access

–Print replenishment labels

–Print replenishment list

Replenishment operation steps

–single step operation

–supply shelves and supply shelves

Delivery (outbound)

See atlas

When it is necessary to leave the warehouse, the system computer sends an instruction to the PDA in the hands of the operator, who locates the corresponding drugs and quantity, takes out the passive label on the drug packaging box, modifies the corresponding data, and sends the data to the system computer.

See atlas

Outbound indication

Different types of issue documents such as sales order issue, purchase return and inter-warehouse transfer are supported.

Track the whole delivery progress.

–Order creation

–Partial allocation, full allocation

–partial delivery, complete delivery

–Partial packaging, complete packaging

–partial shipment, full shipment

–Order closed

–Order cancellation

Different levels of delivery control

–transport by waves
