Warehouse cargo location, management methods and distribution

Partition the entire warehouse, which set the reservoir area, you can set the cargo space. Cargo space refers to the specific location of the goods stored in the warehouse, in the reservoir area by function and location, to store different types of goods. Cargo location settings, you can facilitate the organization of the goods in the warehouse, as well as the management of goods when entering and exiting. The principle of planning cargo position is as follows: the cargo space should be arranged compactly to improve the utilization of storage capacity; it is convenient for receiving, delivery, inspection, packaging and loading and unloading, flexible and reasonable; stable stacking, safe operation; smooth and convenient access; short. CNC acrylic service

“Reserve” plan
“Storage”, where the goods are stored. For ease of management, each “store” of the warehouse / distribution center should be numbered and entered “WMS”
(1) The serial number is generally composed of channel number, shelf number, number of columns and layers;

(2) channel numbers generally use English letters, others use Arabic numerals;

(3) The number of bits depends on the number of bits;

(4) channel number, shelf number, number of columns, layers of eye-catching font made of signs (sign), hanging, paste in the appropriate location. CNC acrylic service



“Reserve” allocation
(1) For the convenience of storage, the items must be kept facing the passage;

(2) Place as far as possible to improve the efficiency of custody;

(3) “shipping” high frequency in the near place, “shipping” low frequency on the distance;

(4) “heavy goods” in the vicinity, “light goods” in the distance:

(5) “large goods” are put in the near place and “small goods” are put in the distance;

(6) “general items” on the lower, “valuables” on the upper;

(7) “heavy goods” on the lower, “light goods” on the upper;

(8) “large goods” are placed on the lower floor, and “small goods” are placed on the upper floor;

(9) to speed up turnover, first-in first-out. CNC acrylic service


Stacking of goods
(1) Similar products according to the date of production, separate storage specifications.

(2) different types of goods were placed on different pallets.

(3) labeled “items”, “label” should be parallel with the passage outward.

(4) Prohibit inversion, strictly forbidden to exceed the stipulated level stacking.

(5) The weight of goods stored on shelves shall not exceed the shelf design load.

(6) When placing goods on pallets, a reasonable distance should be reserved between the pallets so as to facilitate the movement and avoid misplacing the goods.

(7) Manual operation, each cargo tray should be placed on a “storage card.”



“Storage card”
(1) “Memory Card” is a card set on each memory to reflect the status of the stored goods. In the case of manual operation, “memory card” is an effective inventory management tool.

(2) “Storage Card” is mainly used to record the name of the goods stored, storage, access time and quantity, lot number and the number of knots.

(3) The time and quantity of the goods should be recorded on the “memory card” every time the deposit or withdrawal is made. CNC acrylic service



Cargo layout program case
A logistics company’s customers have Wrigley good mouth Limited, Lee Kum Kee, Mrs. music, here only to Wrigley good mouth Limited in the warehouse where the area as an example to introduce the layout of cargo spaces

The company is located in:

The storage of goods in the warehouse mainly in the following five types:

(1) Flat on the ground: the custody of goods directly piled on the ground.

(2) Flat tray type: The custody of goods directly on the tray, then the tray flat on the ground.

(3) Direct stacking: stacking the goods directly on the ground.

(4) pallets stacked code: the goods stacked directly on the pallet, and then placed on the ground tray.

(5) shelf storage: the goods directly on the shelves on the code. CNC acrylic service


According to the regulations, items stored in the warehouse and distribution center shall be placed on the pallet. Therefore, there are two options for the layout of the warehouse: one is the pallet stack type and the other is the tray type shelf system. In warehouse equipment, a shelf is a storage device dedicated to the storage of items. Warehouse management modernization and shelf types, functional development has a direct relationship. The benefits of using shelves for the operation of logistics centers are reflected in:

① can take full advantage of warehouse space, improve storage capacity utilization and storage capacity.

② items accessible, easy to inventory and measurement, can be FIFO.

③ storage items are not squeezed, low loss, to ensure the integrity of the item, to reduce damage.

④ take moisture, dust, anti-theft, anti-sabotage and other measures to improve storage quality.

⑤ conducive to the realization of warehouse mechanization and automation management.

Shelf system is the result of the development of logistics technology, but does not mean that the shelf system is suitable for all warehouses. The shelf system has many restrictions on the logistics system, which can be divided into the following aspects: The selection of the shelf system is part of the long-term operation strategy of the logistics center. After selecting the shelf, the system can not be changed arbitrarily, changing the operation mode of the logistics center and changing the customer structure Will form an obstacle; shelf system should have a higher level of storage management as a guarantee. CNC acrylic service

In particular, there are more varieties of goods, logistics centers and shelving systems with higher requirements on shelf life, which must be supported by better WMS systems. The shelf system is not suitable for storage of heavier items. The vertical movement of heavier items consumes more energy , On the forklift consumption is greater; shelf system requirements for warehouse construction standards higher than the flat warehouse, such as lighting systems, fire protection systems, resulting in the difficulty of the design and construction costs increase; shelf system itself a larger investment, and Requires expensive forklifts to match. Whether to choose the shelf system for the storage of warehouse items, according to the advantages and disadvantages of the shelf combined with the actual situation of enterprises to weigh the choice.


The location optimization software must have the following basic functions:
1, According to the built-in goods attributes or custom attributes to group the goods;

2, the assessment of the best position for each product and the availability of goods;

3, in the case of changes in the classification and properties of goods to adjust the status of facilities;

4, the warehouse will be transformed from the inefficient state to the functional optimization of the state of the mobile implementation of the configuration;

5, three-dimensional graphical or digital analysis of the output. CNC acrylic service


Need a lot of raw data and information for the optimization of the position, for each product need to know the product code, product description, material type, storage environment, shelf life, size, weight, the number of cases per pallet, Include customer order information. Once collected the complete raw data, the choice of what kind of optimization strategy is particularly important. Surveys show that applying some intuitive and obvious method can be misleading and can even lead to the opposite result. An efficient site optimization strategy can increase throughput, improve workforce utilization, reduce occupational injuries, make better use of space and reduce product damage.


Here are some options for optimizing your location:


Periodicity of the cargo space optimization. According to a certain period of time, such as year, quarter, month and so on the liquidity and volume of goods to determine the storage mode and storage mode storage. CNC acrylic service


Sales volume optimization of the goods. In each period of time to determine the storage mode and space allocation.


Unit volume of cargo space optimization. According to the unit volume of a commodity, such as the volume of containers and commodities such as pallets, cases or crates, etc., the division and integration are carried out.


Sorting density optimization of cargo space. Products with a high sorting density should be placed in the gold area and the easiest picking surface. CNC acrylic service


Usually optimization of a cargo is an optimization and simulation tool that operates independently of the warehouse management system WMS. Therefore, using a combination of multiple strategies or alternative strategies to achieve satisfactory results in the virtual warehouse space before implementing the physical implementation may well be a better method of actual use.


Eight rules for cargo optimization
Calculation of cargo optimization is difficult to use numerical formulas and numerical models to describe, usually using some rules or guidelines for non-procedural calculations. The rules play a binding role in the calculation of the data as it converges to the target. Most rules are generic, even though a normal warehouse does not allow random or unplanned placement of items when they are stowed. Different distribution centers or warehouses also make a number of special rules based on their own characteristics and the special attributes of the goods. For example, distribution centers that support retail pharmacies will store similar medicines separately to reduce the chance of picking mistakes, but when storing non-pharmaceuticals, they will be grouped together. CNC acrylic service


Rule one: based on turnover rules. The goods are sorted by descending order according to the turnover rate. The order is divided into several sections (usually divided into three to five sections), and the products belonging to the same section are listed on the same level. According to the principle of location or classified storage method, Storage area for each level of goods, the higher the turnover rate should be closer to the entrance. CNC acrylic service


Rule two: product law of relevance. This can shorten the extraction distance, reduce staff fatigue and simplify inventory. The relevance of the product can be analyzed using historical order data.


Rule three: product identity rules. The so-called principle of identity means the principle of storing the same item in the same place of custody. One of the basic principles by which such operators can simply know the place where the goods are stored and increase the productivity of the logistics center when spending the least amount of time on access to the same item. Otherwise, when the same product is scattered in multiple locations in the warehouse, it may be inconvenient to store and remove the articles, which may cause difficulties in inventorying and mastery of items by the operator. CNC acrylic service


Rule four: the principle of product complementarity. Products of high complementarity should also be kept in close proximity to be quickly replaced by another item when out of stock.


Rule five: product compatibility law. Low compatibility products can not be placed together to avoid compromising quality.


Rule six: product size rules. When deploying the warehouse, we consider both the size of the items and the entire batch of shapes resulting from the same group of items, so that the right amount of space is available to meet a particular requirement. Therefore, in the storage of goods, you must have changes in the size of the position to accommodate different sizes of goods and different volumes. This rule allows items to be stored in the right amount and location, allowing quick dispatch, reduced handling and time. Once the unit size of the storage items is not considered, the storage space may be too large to waste space, or the storage space is too small to be stored. If the entire shape of the storage items is not considered, the entire shape may not be able to be stored at the same place. CNC acrylic service


Rule seven: law of weight characteristics. The so-called weight characteristics of the principle refers to the weight of different items to determine the storage location of goods in high and low positions. In general, heavy objects should be stored on the ground or in the lower position of the shelves, while light objects should be stored in the upper position of the shelves. If the work is carried out by hand, the height below the waist of the person is used to store heavy objects Or large items, while the height above the waist is used to keep light weight items or small items.


Rule eight: product characteristics law. Article characteristics not only involve the danger and perishable items, but also may affect other items, so the layout of the logistics center should be considered. CNC acrylic service


Rules can be based on the characteristics of commonality and personality to develop, such as drug stores must comply with GSP requirements. When the rules are formulated, the rules must also have a clear priority.


Through the optimization of the position can be achieved in a small amount of space can have more sorting surface. For the circulation of goods should meet the ergonomic needs and smooth and convenient access to improve operational efficiency; And for those unpleasant goods hope to take up less space by optimization so that in a small area, there are a variety of products can come Sorting, thereby reducing the distance of picking. In short, to improve ergonomics, space utilization and ultimately reduce costs. CNC acrylic service


Some warehouse management software (WMS) includes cargo optimization modules such as MT (Slotting Optimization), EXE (Exceed Optimize), McHugh (DLx Slotting) and Intek (Warehouse Librarian) Opti-Slot (Descartes) and Easy Profiler (Woodlock Software). Although optimization of the cargo space is a difficult task, the forerunner in the domestic logistics industry has already seen the role of this work in improving the management and potential profitability. We are making unrelenting efforts to narrow the gap with the world standard. CNC acrylic service
