[0023] Figure 2 A schematic diagram of the structure of a jointly purchased device provided in an embodiment of the present application. DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solutions and advantages of this specification more clear, the technical solutions of this application will be clearly and completely described below in conjunction with the specific embodiments of this specification and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in the specification, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0025] The present application provides a method, device and medium for joint procurement, which are described in detail below:

[0026] Figure 1 A flowchart of a joint purchasing method provided in an embodiment of the present application is shown in FIG. Figure 1 As shown, a joint purchasing method provided in an embodiment of the present application may include the following steps:

[0027] S101: receiving product purchase detail information from a supplier node, wherein the product purchase detail information at least includes product information and purchase prices corresponding to each purchase quantity gradient of the product.

[0028] First, each supplier node provides its own product procurement details, which can be stored on the joint procurement platform. The product procurement details include product information, the purchase price corresponding to each purchase quantity gradient of the product, product production date, product expiration date, product type, product production location and other information.

[0029] It should be noted that the supplier node sets different purchase quantity gradients and sets a corresponding purchase price for each purchase quantity gradient. The larger the purchase quantity, the lower the purchase price, so as to promote joint purchasing among buyers.

[0030] S102: receiving joint purchase requests from several purchaser nodes, and generating several corresponding sub-business lists, wherein the sub-business lists at least include target product information, purchase quantity, and preset purchase price range.

[0031] The buyer node that issues the joint procurement request may be one or more buyer nodes, and this application does not limit the number of buyer nodes that issue the joint procurement request.

[0032] Each buyer node that issues a joint purchase request generates a corresponding sub-business list based on the joint purchase request. The sub-business list contains purchase information such as the target product information, purchase quantity, preset purchase price range, etc. The preset purchase price range refers to the purchase price range of the target product that the buyer node can accept.

[0033] S103: Merge the sub-business lists of the same target product into a general business list, and obtain the total purchase quantity of the target product in the general business list.

[0034] Of course, the buyer requests sent by each buyer node will be inconsistent, and the target products to be purchased will also be different. The products purchased during joint procurement should be the same product, because it is necessary to screen each sub-business list, screen out the sub-business lists with the same target products, and merge them into the total business list, so as to obtain the total purchase quantity of the target product in the total business list.

[0035] S104: Based on the product information in the product purchase details information and the purchase prices corresponding to the purchase quantity gradients of the products, the purchase prices of the target products in the general business list are obtained.

[0036] After obtaining the total purchase quantity of the target product, the purchase price corresponding to the purchase quantity gradient of the total purchase quantity is obtained according to the product purchase details information provided by the supplier node.

[0037] S105: Based on the preset purchase price range in each of the sub-business lists and the purchase price of the target product in the total business list, determine whether the purchase price of the target product is within the preset purchase price range.

[0038] In order to enable purchasers to better control procurement costs, this application proposes that it should be determined whether the purchase price of the target product is within the preset purchase price, and suppliers whose purchase price of the target product is within the preset purchase price range should be screened out to truly consider the purchasers so that the subsequent procurement plan generated will be more reasonable.

[0039] S106: Generate a joint procurement plan based on the total procurement quantity of the target product and the procurement price of the target product, send the joint procurement plan to the supplier node and the relevant buyer node, obtain the digital signature of the supplier and the relevant buyer on the joint procurement plan, and generate a purchase order.

[0040] By sending the joint procurement plan to the supplier node and the relevant buyer node and obtaining the digital signatures of the supplier and buyer, the trust between the supplier and the buyer is enhanced, which is conducive to the smooth progress of joint procurement.

[0041] In some embodiments of the present specification, after the purchase order is generated, the method further includes: determining a pickup method for the target product by each of the purchaser nodes, the pickup method including product delivery and product self-pickup; obtaining the address of each of the purchaser nodes that selects the pickup method for product delivery to form an address set of locations to be delivered; based on the address set of locations to be delivered, generating a product delivery route according to preset product delivery rules.

[0042] Considering that multiple buyers of joint procurement may choose different ways to pick up products, two pickup methods are provided: product delivery and product self-pickup. For each buyer who chooses product delivery, considering the issue of transportation costs, centralized distribution can be carried out, and product distribution routes can be generated through preset distribution rules, thereby saving transportation costs.

[0043] In some embodiments of the present specification, after forming the address set of places to be delivered, the method further includes: obtaining the distance between each place to be delivered and the place of shipment based on the address set of places to be delivered and the address of the place of shipment; setting a first weight value for the distance between each place to be delivered and the place of shipment and a second weight value for the purchase quantity of each corresponding buyer node based on the distance between each place to be delivered and the place of shipment and the purchase quantity of each corresponding buyer node; and allocating transportation costs according to the first weight value and the second weight value.

[0044] For example, five buyer nodes jointly purchased the target product T, of which three buyer nodes chose the pickup method for product delivery, namely the first buyer, the second buyer and the third buyer, and the other two buyer nodes chose the pickup method of product self-pickup. When the product is delivered, the transportation cost is borne by the buyer. In order to share the transportation cost more fairly and reasonably, the weight values ​​of the relevant factors are set in advance. Here, the total transportation cost is 100 yuan, and the relevant factors are the distance between each place to be delivered and the place of shipment and the corresponding purchase quantity of each buyer node. The distance weight between each place to be delivered and the place of shipment, that is, the first weight value, is 0.6, and the purchase quantity weight of each buyer node, that is, the second weight value, is 0.4. The distance between the first buyer and the supplier is 50 kilometers, the distance between the second buyer and the supplier is 30 kilometers, and the distance between the third buyer and the supplier is 20 kilometers; the quantity of product T purchased by the first buyer is 60, the quantity of product T purchased by the second buyer is 30, and the quantity of product T purchased by the third buyer is 10. After calculation, the first purchaser node should bear 54 yuan, the second purchaser node should bear 30 yuan, and the third purchaser node should bear 16 yuan.

[0045] In some embodiments of the present specification, after generating the product delivery route according to the preset product delivery rules, the method further includes: based on positioning and tracking technology, monitoring the movement status of the product and obtaining the movement trajectory of the product; obtaining the information of the delivery personnel, and if the movement trajectory of the product deviates from the product delivery route, sending a prompt message to the delivery personnel to correct the trajectory.

[0046] Taking into account the possibility of route deviation during product delivery, the product delivery process is monitored by obtaining the product movement trajectory. Once it is found that the product movement trajectory deviates from the product delivery route, the delivery personnel are contacted in time to correct the product movement trajectory so that the product movement trajectory matches the product delivery route.

[0047] In some embodiments of the present specification, after generating a purchase order, the method further includes: determining an abnormal situation in which the target product is damaged or lost during transportation; obtaining abnormal information of the target product, and sending the abnormal information to each of the buyer nodes and the supplier nodes to confirm whether the buyer will reissue the product; if the buyer node confirms to reissue the product, obtaining the joint procurement plan to confirm whether the corresponding supplier in the joint procurement plan can supply the product; if the corresponding supplier in the joint procurement plan cannot supply the product, generating a new purchase order.

[0048] If a product is damaged or lost during transportation, the abnormal product information can be obtained to confirm whether to replenish the stock, thereby minimizing the losses of suppliers and buyers.

[0049] In some embodiments of the present specification, after obtaining the digital signatures of the suppliers and relevant buyers on the joint procurement plan and before generating the purchase order, the method further includes: prepaying a preset proportion of a deposit based on the quantity of the target products that each buyer needs to purchase; if the buyer node cancels the joint procurement request, the deposit is distributed to the supplier and the remaining buyers as liquidated damages.

[0050] Taking into account that the purchasers who agree to conduct joint procurement may temporarily withdraw, making it impossible for the agreed joint procurement to proceed smoothly, the purchasers are required to pay a deposit in advance. If the purchaser node temporarily withdraws the joint procurement request, the prepaid deposit will be used as liquidated damages to ensure the smooth progress of the joint procurement and protect the rights and interests of suppliers and purchasers.

[0051] In some embodiments of the present specification, after generating a purchase order, the method further includes: analyzing the historical purchasing behavior of each of the purchasers to obtain the purchasing cycle of each of the purchasers for the target product; based on the purchasing cycle of each of the purchasers for the target product, obtaining multiple purchasers with the same purchasing cycle for the target product; obtaining the total purchase quantity of the target product by the multiple purchasers, and correspondingly matching suppliers whose supply quantity meets the total purchase quantity, and generating a long-term joint purchasing cooperation agreement between the multiple purchasers and the suppliers.

[0052] By generating a long-term joint procurement cooperation agreement, the efficiency of joint procurement is improved, and long-term cooperation is achieved between buyers and suppliers. Buyers can purchase at low prices while ensuring a stable supply of products, and suppliers can also increase stable business, thus achieving cooperation and win-win results between buyers and suppliers.

[0053] In some embodiments of the present specification, obtaining the digital signatures of the suppliers and relevant purchasers on the joint procurement plan and generating a purchase order specifically includes: obtaining the digital signatures of the supplier nodes and the relevant purchaser nodes on the joint procurement plan uploaded to the blockchain platform; confirming that the number of the digital signatures is the same as the sum of the number of nodes of the supplier nodes and the relevant purchaser nodes, generating a purchase order, and uploading the purchase order to the blockchain platform.

[0054] By storing the digital signatures of the supplier node and the relevant buyer node on the joint procurement plan on the blockchain platform, and uploading the purchase order to the blockchain platform, the high security and data immutability of the blockchain are utilized to enhance the trust between suppliers and buyers, and between suppliers.

[0055] In some embodiments of the present specification, before obtaining the total purchase quantity of the target product in the total business list, the method also includes: obtaining the inventory balance of the target product of the supplier; when the inventory balance of the target product is lower than a preset inventory lower limit, sending a replenishment reminder to the supplier node; when the inventory balance of the target product is higher than a preset inventory upper limit, sending a stop purchase reminder to the supplier node.

[0056] By monitoring the inventory balance of the target product, when the inventory balance of the target product is lower than the preset inventory lower limit, a replenishment reminder is sent to the supplier node to ensure sufficient product inventory and prevent insufficient inventory; when the inventory balance of the target product is higher than the preset inventory upper limit, a stop purchase reminder is sent to the supplier node to prevent excess product inventory and product backlog.

[0057] In some embodiments of the present specification, after generating a purchase order, the method further includes: monitoring and obtaining feedback information tables from each of the purchasers on the supplier, and generating a corresponding service score table for the supplier based on the feedback information table; based on the service score table, analyzing and obtaining suppliers whose service standards are below the preset supply service standards, and storing the suppliers whose service standards are below the preset supply service standards in a supplier blacklist.

[0058] In order to create a good procurement environment, based on the feedback from the buyer nodes, suppliers with poor services will be added to the supplier blacklist, prohibiting poor suppliers from supplying to buyers, ensuring the service level of joint procurement, and effectively protecting the rights and interests of buyers.

[0059] In summary, the joint procurement method provided by this application enables each purchaser to conduct joint procurement and purchase the required products at a relatively low price, thereby reducing procurement costs. The supplier node sets different procurement quantity gradients and sets a procurement price for each procurement quantity gradient accordingly. The more the procurement quantity, the lower the procurement price, so as to promote joint procurement by purchasers. Each purchaser presets a procurement price range so that the procurement price of the target product is within the procurement price range preset by the purchaser, thereby generating a reasonable joint procurement plan.
