Description

Technical Field

[0001] The present invention relates to the field of commodity information management, and in particular to a commodity information management method based on a supply chain. Background Art

[0002] As the business scope of enterprises continues to expand, the supply chain involves more and more links, including manufacturers, suppliers, distributors, retailers, and logistics service providers. Each link generates a large amount of commodity information, but this information is often scattered in different systems and departments. Manufacturers focus on information such as product production progress and quality inspection, suppliers are concerned about raw material supply and inventory, and distributors and retailers focus on sales data and customer needs. Due to the lack of a unified information management platform, information cannot be smoothly circulated and shared in the supply chain, resulting in information asymmetry and decision-making lags. The transportation process of goods in the supply chain involves multiple modes of transportation and complex logistics networks. During transportation, goods may face risks such as damage, loss, and delays. By installing high-definition cameras, real-time monitoring of goods during transportation can be performed to obtain commodity image information, which provides a possibility for solving problems in traditional commodity information management and promotes the emergence of the present invention. Summary of the invention

[0003] In order to solve the technical problems raised by the above background technology, the present invention provides a commodity information management method based on supply chain.

[0004] The purpose of the present invention can be achieved through the following technical solution: The present invention is a commodity information management method based on a supply chain, comprising the following steps: Step 1. Commodity production management: set up information collection points in each link of the supply chain, including manufacturers, suppliers, distributors and retailers, obtain the type and quantity of initial raw materials of each supplier, mark them as various types of raw materials and store them in the commodity database, obtain the quantity of corresponding production commodities according to the quantity of each type of raw materials, generate a unique barcode for each commodity information currently produced, and each commodity information includes production date, shelf life, production batch and manufacturer. Each user scans the unique barcode through the mobile terminal and identifies the QR code digital number, and sends the QR code digital number to the cloud server. The cloud server receives the QR code digital number, obtains the corresponding commodity information in the commodity database, matches the QR code digital number with the corresponding commodity information, and if the match is successful, sends the commodity information to the query interface of the corresponding user's mobile terminal. If the match fails, an error signal is generated and sent to the query interface of the corresponding user's mobile terminal.

[0005] Step 2: Inventory information analysis: The input end of the inventory information is connected to the output end of the product database, and the online inventory quantity of each product in each warehouse is obtained in real time. The beginning inventory of each product in each warehouse is collected to obtain the beginning inventory of each product in each warehouse, and then the ending inventory of each product in each warehouse is calculated. The average of the obtained beginning inventory and ending inventory is calculated to obtain the inventory average value, marked as GJ. The sales cost data of each product in a specific time period is collected. The sales cost includes the purchase cost, transportation cost and direct expenses related to sales of the product. The sales cost of each product is obtained and marked as GK. The formula Get the inventory turnover rate GD of each commodity in each warehouse within a specific period of time, monitor the outbound quantity of each commodity in each warehouse within a specific period of time, obtain the outbound quantity of each commodity in each warehouse within a specific period of time, mark it as GF, calculate the obtained inventory average value, inventory turnover rate and outbound quantity, and use the formula The inventory safety value GC is obtained, where F1, F2 and F3 are preset proportional coefficients. The preset inventory safety range of the data center is extracted, and the actual inventory safety value is compared with the preset inventory safety range. If the actual inventory safety value is less than the preset inventory safety, it means that the current inventory of the product is tight, and an inventory reduction signal is generated and sent to the corresponding early warning processing system. If the actual inventory safety value is greater than the preset inventory safety range, it means that the current inventory of the product is too much, and an inventory full load signal is generated and sent to the corresponding early warning processing system.

[0006] Step 3: Commodity logistics management: Assign a unique tracking number to each commodity, use the tracking number to query the information of each node in the transportation process in real time, and analyze the transportation distance and transportation time of the commodity, specifically: S1: The output end of the logistics management is connected to the input end of the commodity database. The location information of each warehouse is obtained through the positioning sensor, marked as the initial location, and then the location information of each distributor and the retailer is obtained, marked as the transit location and the terminal location. The initial location and the transit location are connected to obtain each distribution distance, and then the transit location and the terminal location are connected to obtain each retail distance. Each distribution distance and the corresponding retail distance are added to obtain the total transportation distance of each commodity, marked as DT; S2: Get the delivery time of each product in each warehouse, mark it as the initial time point, mark the time point of arrival at the distributor as the transit arrival time point through the tracking number, subtract the initial time point from the transit arrival time point to get the distribution arrival time period, and mark the time point when the product arrives at the retailer's location as the final time point, subtract the transit arrival time point from the final time point to get the retail arrival time period, add the distribution arrival time period and the retail arrival time period to get the total transportation time period of each product, marked as DR; S3: Get the average transportation speed of each commodity through the transportation distance and transportation period of each commodity, marked as DS, and set the preset commodity transportation time, marked as DF; S4: Calculate the total transportation distance of each commodity, the total transportation period of each commodity, the average transportation speed of each commodity and the preset transportation time of each commodity, using the formula The transportation efficiency value of each commodity in each warehouse is obtained, where C1, C2, C3 and C4 are preset proportional coefficients, i represents the number of the commodity in each warehouse, and n represents the total number of commodities in the warehouse; S5: extracting the preset transportation efficiency value of the data center, comparing the preset transportation efficiency value with the transportation efficiency value, and if the preset transportation efficiency value is greater than the transportation efficiency value, generating an abnormal signal and sending it to early warning processing.

[0007] Step 4, sales information feedback: obtain the sales quantity of each commodity at each retailer location within a specific period of time, sum the sales quantity of each commodity at each retailer location, obtain the total sales volume of each commodity within a specific period of time, arrange the total sales volume of each commodity from large to small, obtain the commodity sales curve, obtain the maximum commodity sales volume and the minimum commodity sales volume according to the commodity sales curve, mark the commodity with the maximum sales volume as a preferred commodity, mark the commodity with the minimum sales volume as a cold commodity, obtain the preferred commodity and the cold commodity, generate preferred signals and cold signals for the preferred commodity and the cold commodity and send them to the commodity database, the commodity database receives the preferred signal and the cold signal, takes the corresponding retailer location as the origin, obtains the location of each distributor within the radius, connects the retailer's location with the location of each distributor, obtains each delivery distance, selects the closest delivery distance, selects the corresponding distributor as the target person, the distributor allocates according to the preferred and cold commodities of the corresponding retailer, increases the quantity of the corresponding preferred commodity, and then reduces the quantity of the cold commodity.

[0008] Step 5, early warning processing: the output end of the early warning processing is connected to the input end of the commodity database, and the inventory full load signal and the inventory reduction signal are received, and the inventory full load signal and the inventory reduction signal are sent to the commodity database respectively. The commodity database generates an adjustment instruction according to the inventory full load signal and sends it to the corresponding commodity production line system terminal. The commodity production line system terminal receives the adjustment instruction, obtains the current operating status of each commodity production line, generates a stop instruction and sends it to each commodity production line. Each commodity production line receives the stop instruction and reduces the production task of the commodity, extracts the supply quantity of each type of raw materials in the commodity database, and reduces the supply quantity of the corresponding type of raw materials. If the early warning processing receives a reduction signal, it generates an increase production instruction and sends it to the corresponding commodity production line system terminal. The commodity production line system terminal receives the increase production instruction to increase the operating time of each commodity production line and the supply quantity of each type of raw materials.

[0009] Each transport personnel uploads personal information to the commodity database. The personal information includes name, mobile phone number and transport vehicle license plate number. When an abnormal signal is received, the real-time location information of the corresponding commodity is obtained through the tracking code. The corresponding commodity status is obtained based on the real-time location information of the commodity. If the status of the commodity is displayed as moving, the mobile phone number of the transport personnel of the corresponding transport vehicle is obtained through the commodity database, and an expedited instruction is generated and sent to the corresponding transport personnel's mobile terminal. The transport personnel's mobile terminal receives the expedited instruction and gives priority to delivering the commodity. If the status of the commodity is displayed as stopped, the location information of the corresponding commodity supply chain is obtained, and an expedited instruction is generated and sent to the system processing terminal of the supply chain where the commodity is located.

[0010] Step 6: Product safety monitoring: Install high-definition cameras inside the transport vehicles to monitor the real-time status of each product during transportation and when it arrives at each supply chain. Use the high-definition camera to collect the packaging image of each product before transportation in real time, and mark the transportation image of each product as the original product image. Store the original product image in the product database. Use the camera to collect image information of each product during transportation and when it arrives at each supply chain, mark it as a transport product image, match the original product image with the transport product image, and if there is a difference in the image, mark the product as a difference product, generate a processing signal and send it to the system processing terminal of the supply chain. The system processing terminal of the supply chain receives the signal, processes it and removes the product.

[0011] Extract the production date and validity period of each product in the product database, add the production date and corresponding validity period of each product, obtain the expiration time point of each product, and subtract the current system time point from the expiration time point of each product. If it is a positive number, it means that the corresponding product is an expired product. Obtain the product and destroy it.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: the real-time update and synchronization of information ensures that each link of the supply chain accurately grasps the status of the goods, and the manufacturer can adjust the production plan in time according to the sales data to avoid overproduction or underproduction; the supplier can arrange the delivery time and quantity more accurately, reducing the risk of inventory backlog and out-of-stock; the distributor and the retailer can better manage the inventory and process the order, improve the turnover speed of goods, and thus improve the overall operation efficiency of the supply chain; the efficient information query and sharing function makes the communication between enterprises in each link smoother, reduces the duplication of labor and communication costs caused by information opacity, speeds up the decision-making speed, and promotes the collaborative cooperation of the supply chain. Through the detailed analysis of inventory information, including inventory quantity, location and turnover rate, enterprises can formulate inventory strategies more scientifically. Reasonable control of inventory levels can not only avoid excessive inventory occupying funds and storage space, but also prevent out-of-stock losses caused by insufficient inventory, and improve the efficiency of capital use and inventory management benefits. Accurate inventory information and safety inventory analysis help enterprises to adjust procurement, production and sales strategies in time, optimize inventory structure, and lay a solid foundation for the long-term development of enterprises.
