How to improve the accuracy of e-commerce warehousing inventory

Traditional warehousing through static storage to ensure the continuity of production needs, the rapid development of e-commerce for the industry chain rapid mobility needs more urgent. Relative to other TV shopping, traditional retail, production enterprises, e-commerce warehousing centers are characterized by fast inventory turnover, high efficiency requirements for inbound and outbound warehousing, rich categories (SKU volume), large differences in commodity specifications, and fewer SKUs for outbound orders. In response to this situation, high standards for inventory accuracy have become an inevitable requirement to ensure business.

Today, we will take you from a number of latitude and point of impact on inventory accuracy to analyze one by one, there will be a shallow situation, readers are expected to bear with us.

Definition: Inventory accuracy - the ratio of the number of inventory items to the number of inventory items on the books. It is a key indicator to evaluate the level of warehouse management. The basic PCS algorithm is the number of items actually inventoried / the number of items on the books. Amount algorithm for the corresponding product value of the amount of the ratio, in taking the purchase price, cost price, sales price for the amount of the value of the time, its requirements will be more and more high.

Involved in the inventory accuracy of the various latitudes:

One, the basic framework of the impact

1, the organizational structure of the impact:

Organizational structure set up unreasonably, it will make the warehousing of the internal responsibility and division of labor is not clear. This in turn leads to changes in the structure of the personnel responsibility for inventory quality control. Common cases, if you let the two managers level to manage the different teams will happen to touch the goods, such as sorting and shelving, often occur in the discussion of inventory accuracy responsibility, the phenomenon of shirking responsibility.

2, the impact of personnel:

The main point here is that the personnel themselves are characterized by whether they have serious, responsible, careful traits. And then the good management system, technical equipment, if the irresponsible people to operate are unable to achieve the desired goal of the setup.

3, the impact of management objectives:

The assessment of what to get what, the person in charge of warehousing must be for inventory accuracy indicators have enough attention and sensitivity. This point must be used as a management salary tied to the assessment indicators.

4, the influence of corporate culture:

The direction of the corporate culture must emphasize the team, responsibility, service and other aspects of the content, so that team members through the guidance of the corporate culture, and gradually improve the behavioral traits required by managers.

Two, process design impact

1, third-party supervision

The highest person in charge of warehousing must not be overly confident in the results given by direct subordinates. The naked eye can intuitively find the problem points by the manager himself to supervise and check. For a large number of hidden data must require the company to arrange for third-party departments to monitor, and their own existence as an auxiliary supervision.

2, downstream supervision upstream

Often a company is based on the business process links in the functional completeness of the division of departments. Through the downstream upward supervision, for the overall department head of the global control has been enhanced.

Three, the impact of technology

1, the impact of information systems:

E-commerce company warehousing link for the information system is extremely serious, if there is no supporting fully functional WMS warehousing business process guidance, but simply rely on personnel, the impact of this indicator of the accuracy of the inventory is huge. To put it bluntly, there is no control! Several of the key functions are: bar code applications, PDA applications, inventory management system, personnel information system

2, the impact of related equipment:

The equipment here contains equipment that can directly improve the accuracy of the number of equipment, but also includes supporting systems to support the use of equipment. The more typical use of such as in the warehousing process, through the barcode identification, RFID identification and other equipment for warehousing category distinction and quantity control; in the sorting or inventory process, the system to be picked up to confirm the review of the system.

Four, the impact of goods

1, similarity: in warehousing, shelves, inventory, sorting, stocking and other aspects of the goods will occur to check the link. Checkpoints are basically divided into: commodity name (Chinese characters, letters, product code), commodity appearance (pattern, shape, color, size).

2. Complexity: For cases involving the assembly of goods, attention is paid to prevent the assembly/accessories from omission loss, matching errors and so on. The higher the complexity, the greater the problem between them, often appear to be accessories

3, too small: such as brooches, small jewelry, accessories and other items in the inventory, storage and warehousing will increase the difficulty of the time.

Fifth, the impact of the design of the goods

1, for a product more than one, more than one product, a product

The so-called "bit" refers to the goods, the so-called "goods" refers to SKU (Stock Keeping Unit inventory quantity unit). Keeping Unit Stock Keeping Unit). Each of the three ways have advantages and disadvantages, a product of the way, its space and SKU correspondence is extremely clear, the price is the utilization rate of warehouse capacity or the decline in the amount of custody per unit area. More than one product, the unit area of storage volume of the rise, the price is the decline in sorting efficiency and inventory accuracy of the indirect decline. And a product more than one situation occurs in two cases: a, the number of individual SKU goods is too large a cargo space (or pallet space) can not put; b, the by-product of the adoption of random shelving mode.

2, the sorting method and its supporting distribution

Generally less than a single case will use the "fruit picking" sorting, that is, order by order by sorting method. A single large amount of cases will use the "seeding method" of sorting, in the form of a batch of orders unified sorting and then sub-seeding processing to distinguish between individual orders and the corresponding in-kind. Theoretically, the complexity of the operation of the seeding method will lead to a higher error rate than the picking method. However, if assisted by a distribution wall, information systems (wave summary, distribution operations, etc.) to assist, or can effectively control the error rate of the case, but also to further improve the efficiency of sorting.

3, whether the neighboring goods placed in similar goods

Sorting, shelving link is a human operation, in the process of sorting and shelving is very easy to look at the neighboring goods and shelves wrong sorting and shelving errors. But this does not affect the product line in accordance with the idea of regional centralized management of goods, if the information system does not support the case, the line to do manual redeployment of such management is not to be ignored for the consumption of manpower.

Six, management impact

1, theft: the brunt of the warehouse management to mention this unavoidable problem. For the theft situation is not controlled, there will be a major, irreparable consequences. For the solution to the problem of theft, divided into three aspects of prevention and resolution. First of all, the soft measures, for a new team has not yet found the theft of the incident, to mainly from the publicity aspect of the start, focus on publicity. Through the cultural wall, meetings, training and other channels, to inform employees of the high cost of illegal. If a specific case is found, and traced back to the parties involved, you can join the public security to focus on education and publicity work. Hard measures, with security personnel, equipped with scanning equipment, metal detector doors. By means of equipment to prevent metal-rich high-value 3C goods and jewelry from being entrapped out of the warehouse area. Good security personnel can dig out some non-habitual thieves through the observation of each other's expression. System support, the company's personnel department must first issue a supporting management system, and let the staff countersign. In this way, after the theft occurred, there can be "law" to follow, to avoid unnecessary personnel disputes.

2, fall: commodities due to improper storage process, there will be commodities fall to the bottom of the shelves, between the boxes and other easy to ignore the region. The solution on the one hand to rely on improving the accountability of inventory personnel, on the other hand, can also be avoided through the use of cargo space box, abnormal box, stocking, inventory before the dead end cleanup and many other ways.

Seven, improve the means

1, stocking: stocking for the improvement of inventory accuracy has that is a positive preventive significance. The so-called inventory, is in the daily management process, the goods in the warehouse to clean up the work, which contains the placement of goods, adjacent to the differentiation of goods, abnormal pieces of cleanup and so on several aspects. If the clear method of inventory, determine the cycle of inventory, arrange manpower regular inventory, can greatly reduce the workload of inventory.

2, inventory: essentially inventory behavior does not solve the problem of inventory accuracy, good inventory methods and process control can effectively improve the accuracy of the inventory, that is, the effectiveness of the discovery of inventory problems.

Inventory cycle is generally divided into daily, weekly, monthly, quarterly and annual inventory. As the daily inventory, often will not be a full inventory, generally for the day to move touch goods inventory. Annual inventory is often for the annual warehousing work on inventory management of this piece of work is a summary of the operation. The specific inventory cycle and the type of library, the company's current inventory accuracy, the company's financial needs and other aspects of the comprehensive determination.

Inventory method: the best inventory method is to use PDA equipment in the warehouse goods one by one sweep code inventory. Through the information equipment to drive the verification of goods, than the use of the naked eye to determine the accuracy, credibility will be greatly improved. The most elementary inventory method is to use paper inventory form, in the absence of commodity bar code assistance, through the naked eye on the commodity screening point counting work. Specific companies in what stage of the use of what inventory methods, depending on the company's degree of information technology, the development of the scale, the awareness of managers and many other aspects.

Inventory process: a good inventory process, without regard to the technical aspects of the case. Basic in accordance with the following order is more appropriate. Inventory before (inventory program, responsible for determining and division of labor, inventory tools to prepare, administrative arrangements, time to determine, inventory training) → inventory (mobilization meeting, division of labor again clear, transfer orders to clean up, to ensure that the data is static, inventory start-up) → inventory (data collection, data discrepancies in the comparison, the cause of the analysis, inventory summaries, according to the company's reporting process for approval of the loss of overflow of data, the back office inventory quantity clean-up)

3, performance: If the fault points affecting inventory accuracy on the parties involved and their managers' salaries are not affected, it is difficult to control the continuous improvement of inventory accuracy. Performance tools to make good use of, can play a double the effect of half the effort, can greatly mobilize the enthusiasm of employees.

4, abnormal: abnormal processing in the warehouse when the size of the small role is not obvious, after all, the denominator is small. But when the size of the operation is large, the timeliness of dealing with exceptions is very important. For the handling of abnormal common practices: FAQ (Frequently Asked Questions) FAQ, abnormal follow-up table, abnormal responsibility system.

5, review: Considering that if a person operates, there will generally be an error rate, so the need to review is reflected. In the case of incomplete information systems, there will even be a double review of the situation. The cost is the multiplication of manpower, specifically more emphasis on "quality and customer satisfaction" or "cost" is based on the company's specific stage to choose.

6, receiving: most of the e-commerce enterprises warehousing section of the receiving link is basically a team. Some companies will be named IQC (Incoming Quality Control), basically responsible for the content of the inventory of the number of inventory and quality control. In this link need to emphasize: the reasonable determination of the sampling ratio. If the apparel product line using AQL (ACCEPTABLE QUALITY LEVEL acceptance criteria) industry sampling level of the case, or can be operated. But for some, such as adult products, small appliances and other product lines is not so easy to apply. The key is still according to their own company's size and focus, as well as user characteristics and other aspects, to develop a set of sampling standards in line with their own company. Only in this way can effectively control the balance of labor costs and quality control.

7, on the shelves: inventory inventory clear, if the shelves are wrong, it can really be a low-level error. But this kind of low-level error does happen in our daily management process. For the accuracy of the shelves of the accuracy of the number of shelves on the control of the accuracy of the management has become an important part of our need to control.

8, out of the warehouse: the last good out of the warehouse, means that the most "meat rot in the pot"

Weighing: In addition to providing weight information to the third-party logistics for billing, but also through the weight of the information to match the calibration of the accuracy of the goods out of the warehouse (with the goods in the warehouse information and system support can be).

Weighing.
