[0046] Scenario Example
[0047] In order to facilitate the understanding of the present application, the embodiments of the present application first introduce the present application in combination with the application scenario of the price determination method.
[0048] In an optional implementation of the present application, the price determination method may be applied to an intelligent valuation system, where the intelligent valuation system includes a valuation device.
[0049] The valuation device may be any device with computing, storage and communication functions, for example, a server, a desktop computer, a laptop computer, a tablet computer, a smart phone, etc.
[0050] In an optional embodiment of the present application, the valuation device can respond to a valuation request from a store clerk (the seller of a used product) or a customer (the buyer of a used product) to determine the price of the product to be evaluated; or, the valuation device can respond to a valuation request from a store clerk or a customer to obtain quality inspection information of the product to be evaluated, and then obtain the price of the product to be evaluated based on the quality inspection information of the product to be evaluated.
[0051] In an optional embodiment of the present application, the intelligent valuation system may further include a quality inspection device communicatively connected to the valuation device. Communication between the valuation device and the quality inspection device may be performed using the Transmission Control Protocol (TCP), the User Datagram Protocol (UDP), or the Hypertext Transfer Protocol (HTTP), which is not limited in this embodiment.
[0052] The quality inspection equipment has a quality inspection function. Specifically, the quality inspection equipment can respond to a quality inspection information acquisition instruction sent by the valuation equipment, perform a quality inspection on the product to be evaluated, obtain quality inspection information of the product to be evaluated, and feed it back to the valuation equipment. The valuation equipment then analyzes the quality inspection information to obtain information such as the quality, properties, and defects of the product to be evaluated, and uses the analysis results to estimate the price of the product to be evaluated.
[0053] The communication connection mode between the valuation equipment and the quality inspection equipment can be a wired connection mode or a wireless connection mode.
[0054] Please refer to Figure 1 , Figure 1 A schematic diagram of an application scenario provided for an embodiment of the present application. Figure 1 In the application scenario shown, the valuation device 10 and the quality inspection device 11 are connected via a wire.
[0055] Specifically, Figure 1 The application scenario shown includes a data bus 12 , through which the valuation device 10 and the quality inspection device 11 are connected.
[0056] Please refer to Figure 2 , Figure 2 A schematic diagram of another application scenario provided for an embodiment of the present application. Figure 2 In the application scenario shown, the valuation device 10 and the quality inspection device 11 are connected via a wireless network.
[0057] Specifically, Figure 2 The application scenario shown includes a gateway 13, and the valuation device 10 and the quality inspection device establish a network connection through a wide area network or a local area network, so that the valuation device 10 and the quality inspection device 11 can access the gateway 13, and then the valuation device 10 can control the quality inspection device 11 to execute corresponding instructions.
[0058] Example Method
[0059] This application embodiment also provides a price determination method, please refer to Figure 3 , Figure 3 A flowchart of a price determination method provided in an embodiment of the present application.
[0060] like Figure 3 As shown, the price determination method includes the following steps S301 to S303:
[0061] Step S301: Acquire product information of the product to be evaluated; the product information is used to describe the quality and / or properties of the product to be evaluated.
[0062] The product to be evaluated can be understood as a second-hand product to be sold. The purpose of this application is to determine the sales price of the product to be evaluated so as to provide a reasonable price for the sale of the product to be evaluated.
[0063] In an optional implementation manner of the present application, the product information of the product to be evaluated can be obtained by retrieving the quality inspection information of the product to be evaluated and then parsing the quality inspection information of the product to be evaluated.
[0064] Taking the execution on the valuation device side as an example, the valuation device can respond to the valuation request issued by the user, retrieve the quality inspection report of the product to be evaluated, thereby obtaining the quality inspection information of the product to be evaluated, and then parse the quality inspection information to obtain the product information; or, after receiving the valuation request from the user, the quality inspection device receives the quality inspection information provided by the user, and then parses the quality inspection information to obtain the product information; wherein, the user can be the evaluator who evaluates the product to be evaluated, or can be a consumer who has the intention to purchase the product to be evaluated. This application does not impose any restrictions on this.
[0065] The quality of the product to be evaluated can be understood as information used to describe the newness of the product, whether its appearance is intact, and whether it is worn or damaged. In the embodiment of the present application, the quality of the product to be evaluated is specifically expressed as a quality grade.
[0066] For example, the quality grade of the product to be evaluated can be divided into: brand new, normally used, and partially damaged. Furthermore, in the process of parsing the quality inspection information of the product to be evaluated, if the quality inspection information shows that the performance of the product to be evaluated is consistent with that of a brand new product, the quality grade of the product to be evaluated can be considered brand new; if the quality inspection information shows that the product to be evaluated has good performance but has some wear and tear, the quality grade of the product to be evaluated can be considered normally used; if the quality inspection information shows that the product to be evaluated has defects in product performance but still has recycling value, the quality grade of the product to be evaluated can be considered partially damaged.
[0067] In an optional embodiment of the present application, different qualities of the product to be evaluated correspond to a base price respectively, and the correspondence between the base price and the quality can be pre-recorded in the price list.
[0068] In another optional embodiment of the present application, in order to further reduce the operation and maintenance workload, a correspondence between color grades and benchmark prices can be established in advance based on the Standard Product Unit (SPU), and recorded in the corresponding price list, so that under the same SPU, different color grades correspond to different benchmark prices.
[0069] The SPU can refer to a product model, with different SPUs representing different product models. A product's minimum stock keeping unit (SKU) is a more fine-grained attribute expression than an SPU. Different attributes within the same SPU represent different SKUs. For example, a red and black version of a mobile phone of the same brand and model would have different SKUs.
[0070] During implementation, different fineness grades under the same SPU have their corresponding benchmark prices. In this way, by determining the SPU of the product to be evaluated, the corresponding relationship between the fineness grade and the benchmark price can be determined. Then, after determining the fineness grade of the product to be evaluated, the benchmark price of the product to be evaluated can be determined. Moreover, even for the same SPU, different fineness grades will have different prices. By combining SPU and fineness grade to construct a corresponding relationship with the benchmark price, the price of the product to be evaluated can be maintained from the perspective of SPU. Compared with the traditional price maintenance from the perspective of SKU, this greatly reduces the maintenance workload and maintenance costs, and provides convenience for maintenance management.
[0071] The attributes of the product to be evaluated can be understood as the key features of the product, for example, the brand, model, color, size, capacity and other attribute information of the product to be evaluated.
[0072] For example, when the product to be evaluated is a second-hand mobile phone, the attributes of the product to be evaluated may include: brand A, model X1, red, screen size 6.1 inches, storage capacity 256G; for another example, when the product to be evaluated is a laptop computer, the brand, graphics card model, CPU model and other information of the laptop computer can be used as the attribute information of the product.
[0073] Similar to the quality of the product to be evaluated, the attributes of the product to be evaluated can also be obtained through analysis of quality inspection information. In the embodiment of the present application, different attributes of different products to be evaluated correspond to an attribute price respectively, and the correspondence between the attribute price and the attribute quality inspection of the product to be evaluated can also be pre-recorded in the price list.
[0074] Similarly, a correspondence between the attribute information of the product to be evaluated and the attribute price can also be established based on the SPU, and recorded in a corresponding price list so that different attribute information has corresponding attribute prices under the same SPU.
[0075] In this way, by parsing the quality inspection information of the product to be evaluated, the quality and / or attributes of the product to be evaluated can be distinguished on a coarse-grained basis, laying the foundation for subsequent fine-grained price determination. For example, in one embodiment, the product information of the product to be evaluated includes the quality grade of the product to be evaluated and the attribute information of the product to be evaluated. Determining the price of the product to be evaluated based on the grade price corresponding to the product information includes: determining a base price based on the quality grade; determining an attribute price based on the attribute information; and determining the grade price of the product to be evaluated based on the base price and the attribute price.
[0076] Step S302: There is a grade price corresponding to the product information in the preset price list, and the price of the product to be evaluated is determined based on the grade price corresponding to the product information; the grade price is used to represent the price in the price list corresponding to the quality and / or attributes of the product to be evaluated.
[0077] The grade price corresponding to the product information can be understood as the sum of a base price determined according to the quality grade of the product to be evaluated and an attribute price determined according to the attribute information of the product to be evaluated.
[0078] When the base price and the attribute price can be found in the price list, the base price and the attribute price can be added together to obtain the grade price.
[0079] In another optional embodiment of the present application, in order to more accurately evaluate the price of the product to be evaluated, the grade price of the product to be evaluated can be determined based on the benchmark price and the attribute price, further combined with the defect information of the product to be evaluated.
[0080] Specifically, the product information of the product to be evaluated may also include a defect level.
[0081] The defect grade can also be obtained by analyzing the quality inspection information of the product to be evaluated. During implementation, a correspondence between defect information and defect grade can be pre-established, and the defect information of the product to be evaluated can be obtained based on the quality inspection report. Based on the correspondence between the defect information and the defect grade quality inspection, the defect grade of the product to be evaluated can be determined, thereby providing a basis for subsequently determining a more reasonable grade price for the product to be evaluated.
[0082] In some embodiments, the defect information may include one or more defect items. Accordingly, when determining the defect level of the product to be evaluated based on the defect information, if the defect information includes one defect item, the defect level of the product to be evaluated can be determined based on the defect level corresponding to the defect item; if the defect information includes multiple defect items, the highest defect level can be selected from the defect levels corresponding to each defect item as the defect level of the product to be evaluated.
[0083] Specifically, such as Figure 4 As shown, Figure 4 A schematic diagram of a defect level determination process provided in an embodiment of the present application provides a level matching matrix, wherein the defect levels include 12 defect levels, namely A, B, C, D, E, F, G, H, I, J, K and L, which are in ascending order. Different defect items (1 to 11) will have different defect matching sequences, and multiple defect items will be combined. According to the quality inspection information, the specified defect items can be filled. For example, defect item 1 is the screen. If the screen is intact, defect item 1 is filled with 1. If the screen has few scratches, the defect item can be filled with a sequence of 0 and 1, wherein 1 is filled from high defect level to low defect level (i.e. Figure 4 The more 1s there are, the better the quality inspection results are, and the lower the corresponding defect level is; conversely, 0s are filled from low defect levels to high defect levels (i.e. Figure 4 (filled from left to right in the matrix). The more 0s there are, the worse the quality inspection result, and the higher the corresponding defect grade. After filling the grade matching matrix based on the quality inspection information of the product to be evaluated, the defect grade can be determined based on the filling results. When determining the defect grade, if all defect items have a grade of 1, it means that the grade is matched. The highest grade in the matched grade matching matrix is the final grade hit by the combination of these defect items. For example: Figure 4 In the example, the defect information includes defect items 4, 7, 9, 10, and 11. Among these five defect items, only defect item 11 has the highest level of J. Therefore, the defect level that the defect information ultimately hits is level J.
[0084] After determining the defect grade of the product to be evaluated, the corresponding defect price can be obtained based on the defect grade, and then, based on the benchmark price and the attribute price, combined with the defect price, the grade price of the product to be evaluated can be obtained, and then the price of the product to be evaluated can be determined based on the grade price.
[0085] Step S303: If there is no grade price corresponding to the product information in the price list, the product information is processed based on a pre-trained price determination model to obtain an estimated grade price of the product to be evaluated, and the price of the product to be evaluated is determined based on the estimated grade price of the product to be evaluated; the price of the product to be evaluated includes the sales price of the product to be evaluated.
[0086] When there is no equivalent price corresponding to the product information in the price list, it means that the price of the product to be evaluated cannot be determined using the price list. In this case, in order to quickly and conveniently obtain the price of the product to be evaluated, the grade price of the product to be evaluated can be estimated using a pre-trained price determination model.
[0087] Among them, the price determination model can be understood as a neural network model. In the process of specific application, this application adopts machine learning (ML) to train and obtain the consultation model. Machine learning (a multi-disciplinary interdisciplinary subject involving probability theory, statistics, approximation theory, convex analysis, algorithm complexity theory and other disciplines) is dedicated to studying the acquisition of new knowledge or skills through training samples, reorganizing existing knowledge structures and continuously improving its own performance. Machine learning usually includes artificial neural networks, belief networks, reinforcement learning, transfer learning, inductive learning and other technologies, and is a branch of artificial intelligence (AI) technology.
[0088] In an optional embodiment of the present application, the product information of the product to be evaluated can be input into the price determination model, so that the price determination model analyzes the product information to obtain the color grade, attribute information and defect grade of the product to be evaluated, and obtains the benchmark price, attribute price and defect price of the product to be evaluated.
[0089] In this case, the price determination model can be trained in the following way:
[0090] First, obtaining the sample color grade, sample attribute information, and sample defect grade of the sample product;
[0091] Secondly, obtaining a sample base price, a sample attribute price, and a sample defect price of the sample product;
[0092] Finally, the sample color grade, sample attribute information, sample defect grade, sample benchmark price, sample attribute price and sample defect price are used as training samples to train the price determination model.
[0093] The training samples used to train the price determination model may be those recorded in the price list, or may be product information of evaluated products and prices corresponding to different product information determined by manual pricing.
[0094] In another optional embodiment of the present application, the quality inspection report of the product to be evaluated can also be input into the price determination model so that the price determination model can parse the quality inspection report and obtain the corresponding benchmark price, attribute price and defect price based on the parsing results.
[0095] In this case, the price determination model can be trained in the following way:
[0096] First, obtain a sample quality inspection report of the sample product, as well as a sample base price, a sample attribute price, and a sample defect price of the sample product;
[0097] Secondly, the sample quality inspection report, as well as the sample base price, sample attribute price and sample defect price of the sample product are used as training samples to train the price determination model.
[0098] In actual application, if there is no grade price corresponding to the product information in the price list, and after obtaining the benchmark price, attribute price and defect price of the product to be evaluated through the above-mentioned price determination model, the product information of the product to be evaluated and the benchmark price, attribute price and defect price can be entered into the price list to complete the update of the price list, so as to improve the valuation efficiency when subsequently evaluating products with the same product information.
[0099] In another optional embodiment of the present application, the price of the product to be evaluated can also be directly determined by the price determination model, that is, the quality inspection report of the product to be evaluated is input into the price determination model, so that the price determination model analyzes the quality inspection report to obtain the price of the product to be evaluated.
[0100] In this case, the price determination model can be trained in the following way:
[0101] First, obtain a sample quality inspection report of the sample product and a sample price of the sample product;
[0102] Secondly, the sample quality inspection report and the sample price are used as training samples to train the price determination model.
[0103] Furthermore, after obtaining the price of the product to be evaluated, in order to determine whether there is a risk of loss when the product to be evaluated is sold at this price, the steps of determining the price of the product to be evaluated in steps S302 and S303 include:
[0104] When the grade price of the product to be evaluated or the estimated grade price of the product to be evaluated is greater than the preset risk price, the grade price of the product to be evaluated or the estimated grade price of the product to be evaluated is used as the price of the product to be evaluated.
[0105] In an optional embodiment of the present application, the preset risk price may be the recovery price of the product to be evaluated, that is, when the grade price or the estimated grade price of the product to be evaluated is greater than the recovery price, the grade price or the estimated grade price will be used as the price of the product to be evaluated.
[0106] In another optional embodiment of the present application, considering that during the product recycling process, the recycling cost of the product is not only the recycling price of the product itself, but also the transportation cost and labor cost of the product need to be considered.
[0107] Therefore, in determining the risk price, it is also necessary to combine the recovery price with the recovery channel coefficient of the product to be evaluated. This allows for a reasonable price assessment of the product to be evaluated in terms of its recovery cost loss, thereby determining a more reasonable price based on different valuation channels.
[0108] In an optional implementation of the present application, when determining the recycling channel coefficient of the product to be evaluated, the recycling channel of the product to be evaluated can be determined first, and then the corresponding recycling channel coefficient can be obtained based on the recycling channel.
[0109] When constructing the correspondence between the combination of the grade price range and the recycling channel and the cost item coefficient, the correspondence between the combination of the grade price range and the recycling channel and the recycling channel coefficient is constructed. That is, the correspondence between the combination of the grade price range and the recycling channel and the recycling channel coefficient is established. In this way, for the same valuation channel, the cost item coefficient will be different depending on the price range of the grade price. Moreover, for the same grade price range, the recycling channel coefficient will also be different depending on the recycling channel. For example, under the same recycling channel, if the grade price is 2,000 yuan, the corresponding recycling channel coefficient for the price range (0, 1,500) is 3%; the corresponding recycling channel coefficient for the price range [1,500, 3,000] is 5%; and the corresponding recycling channel coefficient for the price range [3,000, 4,500) is 8%. Therefore, the recycling channel coefficient for a grade price of 2,000 yuan is 5%.
[0110] In this way, by constructing the corresponding relationship between the combination of grade price ranges and recycling channels and the recycling channel coefficient, the determination of the recycling channel coefficient can be regulated and maintained, which reduces the maintenance workload and improves the maintenance efficiency.
[0111] In another optional embodiment of the present application, in order to improve the price credibility of the product to be evaluated during the price evaluation of the product to be evaluated, the recovery channel coefficient can also be combined when determining the price of the product to be evaluated based on the grade price or estimated grade price corresponding to the product grade.
[0112] Specifically, determining the price of the product to be evaluated based on the grade price corresponding to the product information; or determining the price of the product to be evaluated based on the estimated grade price of the product to be evaluated includes:
[0113] The price of the product to be evaluated is determined according to the grade price or the estimated grade price and the recovery channel coefficient of the product to be evaluated.
[0114] In the embodiment of the present application, the price of the product to be evaluated is determined based on the grade price or the estimated grade price and the recovery channel coefficient of the product to be evaluated, which can be expressed by the following formula (1):
[0115] Q=(1+D)A (1);
[0116] Wherein, Q represents the price of the product to be evaluated, A represents the estimated grade price or grade price of the product to be evaluated, and D represents the recovery channel coefficient.
[0117] Furthermore, when the grade price of the product to be evaluated or the estimated grade price of the product to be evaluated is less than or equal to the preset risk price, in order to avoid risks and prevent relevant staff from selling the product to be evaluated based on the grade price, the method further includes:
[0118] issuing a prompt message, wherein the prompt message is used to prompt that the grade price of the product to be evaluated or the estimated grade price of the product to be evaluated has a risk of loss;
[0119] After receiving confirmation information for the prompt information, the grade price of the product to be evaluated or the estimated grade price of the product to be evaluated is determined as the price of the product to be evaluated.
[0120] When the staff related to the confirmation information confirms that the product to be evaluated is in the process of clearing inventory, or that the product to be evaluated has suffered secondary damage and depreciated during the recycling or storage process, the estimated grade price or the grade price can be used as the price to sell the product to be evaluated.
[0121] In summary, the price determination method provided by this application determines the price of the product to be evaluated based on the grade price corresponding to the product information in the preset price list. If there is a grade price corresponding to the product information in the price list, the product information is processed based on a pre-trained price determination model to estimate the grade price, and the price of the product to be evaluated is determined based on the estimated grade price.
