Description

Technical Field

[0001] The present invention belongs to the technical field of vehicle parts price management, and in particular relates to a method, device, equipment and medium for generating prices of outsourced parts for special-purpose vehicles. Background Art

[0002] Special vehicle manufacturing involves many parts, and the price of each part directly affects the cost of the final product. Accurate price management can monitor and regulate the procurement cost of parts in real time to avoid unnecessary waste, and can also ensure the timely supply of parts and avoid production delays caused by parts shortages.

[0003] At present, parts are processed by outsourcing, and the existing price calculation method relies on manual search and calculation in spreadsheets. This mode is not only inefficient, but also prone to errors. In addition, since each business personnel is faced with a huge amount of parts information, deviations in any link in the calculation may lead to errors in the final price, which in turn leads to losses for the company. Specifically, on the one hand, the method of searching for prices on various documents on spreadsheets is relatively scattered, lacking unified management and auditing, resulting in the need for manual data entry to maintain ERP price data. The entire process consumes a lot of manpower for calculation, search and maintenance, and is prone to reducing audits and passing off inferior products as superior ones. On the other hand, manual price calculation is labor-intensive, time-consuming, and error-prone, and it is not easy to make dynamic adjustments when a single project changes. In addition, each salesperson is faced with a huge amount of different parts information, and deviations in any link in the calculation will bring great difficulties to the final price correction. Summary of the invention

[0004] In a first aspect, an embodiment of the present application provides a method for generating prices of purchased parts for a special-purpose vehicle, comprising the following steps: S1. Classify the purchased parts of special vehicles into the same family according to their constituent elements to obtain a parts classification information table, and then generate a same family parts information table in combination with the purchased parts information obtained from the ERP system; S2. According to the manufacturing process of purchased parts, establish a price calculation model for parts of the same family based on material costs, processing costs and purchased accessories costs; S3. Use the same family parts price calculation model to calculate the standard price of each family of purchased parts, and compare it with the actual purchase price to calculate the difference rate; S4. When the difference rate is within the preset threshold range, the price-to-weight ratio of the same family of parts is calculated, and then the price-to-weight ratio is associated and matched with the parts classification information table to build a price calculation benchmark database; S5. Obtain the target outsourced parts, identify and compare them with the outsourced parts in the price calculation benchmark database, find the corresponding price-to-weight ratio, and then calculate the price of the target outsourced parts based on the net weight of the target outsourced parts.

[0005] Furthermore, the specific steps of step S1 are as follows: S11. Classify the purchased parts of the special vehicle into the same family according to the process, function and structural elements to obtain a parts classification information table; S12. Query the purchased parts information within the statistical time period from the ERP system and sort them in descending order according to the purchase volume; S13. Integrate the parts classification information table and the purchased parts information in descending order into a same-family parts information table, and the same-family parts information table includes n same-family parts information tables, each same-family parts information table includes m same-family parts and the drawing number, name, annual purchase volume, annual purchase frequency, purchase unit price, purchase price, material net weight and specific pictures at different spatial angles of each same-family part, m ≥ 20.

[0006] Furthermore, the specific steps of step S2 are as follows: S21. Locate each family in the same family component information table; S22. Maintain the cost BOM for the located family, determine the material process quota, material planned price, material net weight and scrap price based on the cost BOM, and calculate the material cost using the following formula: Material cost = material process quota * material planned price - (material process quota - material net weight) * scrap price; S23. Maintain the process steps of the located family, determine the quota and standard rate of each process of the processing method, and calculate the processing fee of each process and the total processing fee in the following way: The processing fee corresponding to each process = quota * standard rate; Total processing fee = the sum of the processing fees of each process; S24. Maintain the purchased accessories as finished product purchase parts for the located family, determine the quantity and price of the accessories, and calculate the purchased accessories fee in the following way: Cost of purchased accessories = quantity of accessories * price of accessories; S25. The sum of material costs, processing costs and outsourced parts costs is used as a component price calculation model for the positioned family; S26. Determine whether the family in the same family component information table has been located; If yes, go to step S27; If not, locate the next cluster and return to step S22; S27. Integrate the price calculation models of components of each family to obtain the price calculation model of the same family components of each family.

[0007] Furthermore, the specific steps of step S3 are as follows: S31. locate a family, and use the price calculation model of the same family components of the located family to calculate the standard price of each purchased component in the family; S32. Multiply the standard price of each purchased component of the positioning family by the corresponding unit purchase quantity and then sum them to obtain the standard unit time purchase amount β; S33. Sum the actual prices of purchased parts of the positioning family found in the same family parts information table to obtain the actual purchase amount per unit time α; S34. Calculate the difference rate θ based on the standard unit time purchase amount β and the actual unit time purchase amount α using the following formula: θ=(α-β) / α.

[0008] Furthermore, the specific steps of step S4 are as follows: S41. Obtaining a preset difference rate threshold range, and identifying whether the calculated difference rate θ is within the value check rate threshold range; If yes, go to step S43; If not, proceed to step S42; S42. Adjust the calculation factors of the standard unit time purchase amount, and return to step S11; S43. Obtain the same family parts information table to find the net weight of the material of each part of the located family k1, k2 ... km, and calculate the price-to-weight ratio λ with the unit purchase volume g1, g2 ... gm of each part of the corresponding located family through the following formula: λ=α / (k1*g1+k2*g2+……+ km*gm); S44. Repeat steps S31-S43 to calculate the price-to-weight ratio of each family of parts λ1, λ2 ... λn; S45. The price-to-weight ratios λ1, λ2, ... λn of each family of parts are managed and matched with the information tables of n parts of the same family through the parts drawing numbers to form a price calculation benchmark database, which includes the drawing number, name, family, specific pictures at different spatial angles, material prices and material net weights.

[0009] Furthermore, in step S42, the calculation factors of the standard unit time purchase amount are adjusted, specifically including: Compare the differences between the standard price components of each component, and adjust the standard price components whose differences are greater than a threshold; Adjust the parts classification information table to increase the number of parts of the same family; Check whether any sub-items in the price calculation model for parts of the same family are missing.

[0010] Furthermore, the specific steps of step S5 are as follows: S51. Obtain image data of target purchased parts at specific different spatial angles through an image acquisition device and perform preprocessing; S52. Compare and analyze the preprocessed image data of the target outsourced parts according to the predetermined image angle to obtain the image recognition result corresponding to the target outsourced parts; S53. The user determines whether the image recognition result matches the actual target purchased parts; If yes, go to step S55; If not, proceed to step S54; S54. Obtain the correction data input by the user, correct the object type of the target purchased parts, and then use the price calculation reference database to confirm the price information of the target purchased parts according to the correction result, generate the price of the target purchased parts and store it synchronously with the correction data, and end; S55. Confirm the price calculation information of the target outsourced parts through the price calculation reference database, generate the price of the target outsourced parts and store it.

[0011] In a second aspect, the embodiment of the present application further provides a device for generating prices of purchased parts for special-purpose vehicles, comprising: A component information table building unit for the same family is used to classify the purchased components of the special vehicle into the same family according to the constituent elements, obtain a component classification information table, and then generate a component information table for the same family in combination with the purchased component information obtained from the ERP system; The unit for constructing the price calculation model for the same family of parts is used to establish the price calculation model for the same family of parts according to the manufacturing process of the purchased parts, the material cost, the processing cost and the cost of the purchased accessories; The difference rate calculation unit is used to calculate the standard price of each family of purchased parts using the same family parts price calculation model, and compare it with the actual purchase price to calculate the difference rate; A price calculation benchmark database construction unit is used to calculate the price-to-weight ratio of the same family of parts when the difference rate is within a preset threshold range, and then associate and match the price-to-weight ratio with the parts classification information table to construct a price calculation benchmark database; The price calculation unit of the target outsourced parts is used to obtain the target outsourced parts, identify and compare them with the outsourced parts in the price calculation benchmark database, find the corresponding price-to-weight ratio, and then calculate the price of the target outsourced parts in combination with the net weight of the target outsourced parts.

[0021] In the specific steps of the method for generating the price of purchased parts for special vehicles, which will be described in detail below, various embodiments of the present disclosure will be described more comprehensively. The present disclosure may have various embodiments, and adjustments and changes may be made therein. However, it should be understood that there is no intention to limit the various embodiments of the present disclosure to the specific embodiments disclosed herein, but the present disclosure should be understood to cover all adjustments, equivalents and / or alternatives that fall within the spirit and scope of the various embodiments of the present disclosure.

[0022] For example, in the field of special vehicle manufacturing, there are many types of parts and components, and the price of each item is directly related to the cost structure of the final product. Implementing a precise price management strategy can effectively track and control the procurement cost of parts and components, prevent resource waste, and ensure timely supply of parts and components, thereby avoiding the risk of production stagnation caused by shortages.

[0023] At present, the processing of parts and components is outsourced, while the price calculation process is highly dependent on manual operation, specifically manually searching and calculating prices in spreadsheets. This model has many disadvantages: low efficiency and frequent errors. Faced with a large amount of parts and components data, each business person may cause price errors if he is not careful during the calculation process. Specifically, first of all, there is a lack of uniformity in the search and management of price data. Business personnel need to search for prices on various documents in different spreadsheets, which is not only inefficient but also prone to data inconsistency. At the same time, due to the lack of an effective audit mechanism, price data in the ERP system needs to be manually entered. This process not only consumes a lot of manpower for calculation, search and maintenance, but may also cause data entry errors and lax audits. Secondly, the manual price calculation method is labor-intensive, time-consuming, and prone to errors. Due to the wide variety of parts and components and the complex price calculation process, changes in a single project often require the entire calculation process to be readjusted, which not only increases the difficulty of work but also reduces work efficiency. Finally, faced with a large amount of parts and components information, business personnel may cause errors in the final price if they are not careful during the calculation process. Due to the numerous calculation links, once a deviation occurs in one link, it will become extremely difficult to correct the error, which not only increases the operational risk of the enterprise, but also affects the market competitiveness of the enterprise.

[0024] In response to the above problems, this embodiment provides a method for generating prices for purchased parts for special-purpose vehicles. The method can narrow the scope of price calculation, simplify the amount of new data, improve the controllability of the price generation process, and solve the problems of inconsistent price standards and heavy workload in manual calculation.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] See also Figure 1 The figure is a flow chart of a method for generating prices of purchased parts for special-purpose vehicles in a specific embodiment, the method comprising: S1. Classify the purchased parts of special vehicles into the same family according to their constituent elements to obtain a parts classification information table, and then generate a same family parts information table in combination with the purchased parts information obtained from the ERP system; It should be noted that, taking the hook components as an example, although they have different structures (distinguishable by different drawing numbers), they belong to the same hook category and have the same function, so the hook category components are classified as the same group, and the ERP system records the detailed information of the purchased parts; By collecting parts information comprehensively and accurately, we can provide a basis for subsequent price calculation. The completeness of the collected parts information helps to ensure the accuracy of price calculation, and accuracy avoids price deviation caused by incorrect information. S2. According to the manufacturing process of purchased parts, establish a price calculation model for parts of the same family based on material costs, processing costs and purchased accessories costs; It should be noted that classifying parts into the same family simplifies the complexity of price calculation. Through classification, parts with similar characteristics can be treated as a whole, thereby reducing the amount of calculation and improving calculation efficiency. At the same time, classification also helps to identify price trends and provide a basis for price adjustment. S3. Use the same family parts price calculation model to calculate the standard price of each family of purchased parts, and compare it with the actual purchase price to calculate the difference rate; It should be noted that the construction of a price calculation model for the same family of parts makes the price calculation more reasonable. The price calculation model for the same family of parts can comprehensively consider multiple factors such as cost, market supply and demand, etc., so as to obtain a price that is closer to reality. In addition, the model is also adjustable and can be flexibly adjusted according to market changes and corporate needs; The difference rate is calculated by taking into account the impact of component characteristics and market conditions on prices. The difference rate reflects the degree of price deviation caused by changes in component characteristics or market conditions, which helps to ensure price flexibility and adaptability. By adjusting the difference rate, the impact of component characteristics on prices can be more accurately reflected; S4. When the difference rate is within the preset threshold range, the price-to-weight ratio of the same family of parts is calculated, and then the price-to-weight ratio is associated and matched with the parts classification information table to build a price calculation benchmark database; It should be noted that the construction of a price calculation benchmark database provides a baseline for price adjustments. The benchmark price reflects the reasonable price level under standard conditions, which helps to ensure fair and reasonable prices. At the same time, the benchmark price is also the basis for subsequent price adjustments, providing a basis for price adjustments. S5. Obtain the target purchased parts, identify and compare them with the purchased parts in the price calculation benchmark database, find the corresponding price-to-weight ratio, and then calculate the price of the target purchased parts in combination with the net weight of the target purchased parts; It should be noted that determining the final price completes the core task of price generation, and reviewing and adjusting the final price ensures that the price is compliant and reasonable.

[0027] In this embodiment, by classifying parts into the same family and combining the ERP system information to generate a parts information table for the same family, and based on this, a price calculation model is established to achieve automatic generation and precise management of prices. This not only improves the efficiency and accuracy of price calculation, but also effectively reduces the risk of errors caused by manual calculation, providing strong support for the company's cost control and supply chain management.

[0028] Further, as a refinement and expansion of the specific implementation of the above embodiment, in order to fully illustrate the specific implementation process of this embodiment, another method for generating the price of purchased parts for special vehicles is provided, such as Figure 2 and Figure 3 As shown, the method comprises the following steps: S1. Classify the purchased parts of the special vehicle into the same family according to the constituent elements to obtain a parts classification information table, and then generate a same family parts information table in combination with the purchased parts information obtained from the ERP system; the specific steps of step S1 are as follows: S11. Classify the purchased parts of the special vehicle into the same family according to the process, function and structural elements to obtain a parts classification information table; S12. Query the purchased parts information within the statistical time period from the ERP system and sort them in descending order according to the purchase volume; For example, the purchased parts information within two years is sorted to obtain a detailed list in descending order based on the purchase volume within two years; S13. Integrate the parts classification information table and the purchased parts information in descending order into a same-family parts information table, and the same-family parts information table includes n same-family parts information tables, each same-family parts information table includes m same-family parts and the drawing number, name, annual purchase volume, annual purchase frequency, purchase unit price, purchase price, material net weight and specific pictures of different spatial angles of each same-family part, m ≥ 20; S2. According to the manufacturing process of purchased parts, a price calculation model for the same family of parts is established according to the material cost, processing cost and purchased accessories cost; the specific steps of step S2 are as follows: S21. Locate each family in the same family component information table; S22. Maintain the cost BOM for the located family, determine the material process quota, material planned price, material net weight and scrap price based on the cost BOM, and calculate the material cost using the following formula: Material cost = material process quota * material planned price - (material process quota - material net weight) * scrap price; It should be noted that before the process department calculates the standard price, it should correctly decompose the BOM of the parts and components, expand them layer by layer from top to bottom, until the bottom layer, and confirm the material type and specification, the hierarchical BOM structure of the parent and child items, the material process quota, the net weight of the material, and the quantity relationship between the parent and child items; Before calculating the standard price, the purchasing department maintains the planned price of raw materials and scrap prices within the period according to the purchasing agreement, and confirms the correspondence between materials and cost items to facilitate query during calculation; For example, if auxiliary materials such as paint and welding wire are included in the cost BOM, they will be calculated when calculating the material cost of their parent items. If they are not included in the cost BOM, they will not be calculated. Specifically, the material process quota is the quotient obtained by dividing the number of workpieces produced in batch layout for special-shaped sheet metal parts, such as ≥10 vehicles, by the consumed sheet metal quota; the waste quota after layout with a material utilization rate of less than 85% is allocated to each piece for material residual value calculation; Before calculating the standard price, the purchasing department maintains the planned price of raw materials and scrap prices within the period according to the purchasing agreement, and confirms the correspondence between materials and cost items to facilitate query during calculation; S23. Maintain the process steps of the located family, determine the quota and standard rate of each process of the processing method, and calculate the processing fee of each process and the total processing fee in the following way: The processing fee corresponding to each process = quota * standard rate; Total processing fee = the sum of the processing fees of each process; It should be noted that the process department should correctly maintain the process processing methods and process processing equipment of the purchased parts before calculating the standard price; Before calculating the standard price, the process department should correctly maintain the quota information of the processing method. The labor quota determines the processing time corresponding to the unit product, distinguishes the processing time under different processing methods, and the weight quota is determined according to the product, and the area is determined according to the product process requirements; Before calculating the standard price, the standard rate information needs to be correctly maintained; the standard rate includes various expenses such as equipment depreciation, fuel, worker wages, workshop management fees, freight, etc. per hour, excluding profits; different standard rates are set for the same type of equipment in different processing units according to equipment depreciation; the pricing method is defined in the standard rate maintenance, including three calculation methods: by working hours, weight, and area; specifically, calculation by working hours refers to the standard rate per working hour; calculation by weight refers to the standard rate per unit weight; calculation by area refers to the standard rate per unit area; S24. Maintain the purchased accessories as finished product purchase parts for the located family, determine the quantity and price of the accessories, and calculate the purchased accessories fee in the following way: Cost of purchased accessories = quantity of accessories * price of accessories; It should be noted that purchased parts are finished products purchased directly from the market by the supplier and then used in the production of purchased parts by the company. Before the standard cost calculation is performed, the process department correctly maintains the purchase type in the process route definition, and the purchasing department correctly maintains the corresponding parts price according to the purchase type. The price basis is calculated based on the purchase price at the time of plan issuance. If there is no historical price, the actual purchase price at the time of submission shall prevail. S25. The sum of material costs, processing costs and outsourced parts costs is used as a component price calculation model for the positioned family; S26. Determine whether the family in the same family component information table has been located; If yes, go to step S27; If not, locate the next cluster and return to step S22; S27. Integrate the component price calculation models of each family to obtain a component price calculation model of the same family in each family; S3. Use the same family parts price calculation model to calculate the standard price of each family of purchased parts, and compare it with the actual purchase price to calculate the difference rate; the specific steps of step S3 are as follows: S31. locate a family, and use the price calculation model of the same family components of the located family to calculate the standard price of each purchased component in the family; S32. Multiply the standard price of each purchased component of the positioning family by the corresponding unit purchase quantity and then sum them to obtain the standard unit time purchase amount β; S33. Sum the actual prices of purchased parts of the positioning family found in the same family parts information table to obtain the actual purchase amount per unit time α; S34. Calculate the difference rate θ based on the standard unit time purchase amount β and the actual unit time purchase amount α using the following formula: θ = (α - β) / α; It should be noted that the standard price of the first purchased component of the same family is obtained by adding the material cost, processing cost and outsourced accessory cost. The standard price of other components of the same family is obtained according to the above steps. It is multiplied by the corresponding annual purchase volume g and then added up to obtain the annual purchase amount β of the component. The component purchase price h is obtained from the information table of components of the same family, and it is added to obtain the actual annual purchase amount α. The difference rate between the two is calculated as θ= (α-β) / α; S4. When the difference rate is within the preset threshold range, the price-to-weight ratio of the same family of parts is calculated, and then the price-to-weight ratio is associated with the parts classification information table to build a price calculation benchmark database; the specific steps of step S4 are as follows: S41. Obtaining a preset difference rate threshold range, and identifying whether the calculated difference rate θ is within the value check rate threshold range; If yes, go to step S43; If not, proceed to step S42; For example, the difference rate threshold range may be set to [5%, 15%]; S42. Adjust the calculation factors of the standard unit time purchase amount, and return to step S11; S43. Obtain the same family parts information table to find the net weight of the material of each part of the located family k1, k2 ... km, and calculate the price-to-weight ratio λ with the unit purchase volume g1, g2 ... gm of each part of the corresponding located family through the following formula: λ=α / (k1*g1+k2*g2+……+ km*gm); S44. Repeat steps S31-S43 to calculate the price-to-weight ratio of each family of parts λ1, λ2 ... λn; S45. The price-weight ratio λ1, λ2, ... λn of each family of parts is managed and matched with n parts information tables of the same family by parts drawing numbers to form a price calculation benchmark database, wherein the price calculation benchmark database includes drawing number, name, family, specific pictures of different spatial angles, material prices and net weight of materials; It should be noted that the specific different spatial angle pictures refer to the image data collection of the parts by the image collection equipment at specific different angles, and the specific different angles are the front view, side view, top view, and axial view. After the collection, the pre-processing of the photos includes but is not limited to noise reduction, reduction, rotation, resolution adjustment, etc., so as to standardize the images and obtain the image information data; S5. Obtain the target purchased parts, identify and compare them with the purchased parts in the price calculation benchmark database, find the corresponding price-to-weight ratio, and then calculate the price of the target purchased parts in combination with the net weight of the target purchased parts; the specific steps of step S5 are as follows: S51. Obtain image data of target purchased parts at specific different spatial angles through an image acquisition device and perform preprocessing; S52. Compare and analyze the preprocessed image data of the target outsourced parts according to the predetermined image angle to obtain the image recognition result corresponding to the target outsourced parts; S53. The user determines whether the image recognition result matches the actual target purchased parts; If yes, go to step S55; If not, proceed to step S54; S54. Obtain the correction data input by the user, correct the object type of the target purchased parts, and then use the price calculation reference database to confirm the price information of the target purchased parts according to the correction result, generate the price of the target purchased parts and store it synchronously with the correction data, and end; S55. Confirm the price calculation information of the target outsourced parts through the price calculation reference database, generate the price of the target outsourced parts and store it.

[0030] In step S42, the calculation factors of the standard unit time purchase amount are adjusted, specifically including: Compare the differences between the standard price components of each component, and adjust the standard price components whose differences are greater than a threshold; Adjust the parts classification information table to increase the number of parts of the same family; Check whether any sub-items in the price calculation model for parts of the same family are missing.

[0031] It should be understood that the order of execution of the steps in the above embodiment does not necessarily mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiment of the present invention.

The user end only needs to place the target outsourced parts on the equipment to automatically identify and obtain the target outsourced parts price-to-weight ratio and the net weight of the material. The price is generated after confirmation by the user end, thereby narrowing the price calculation range, simplifying the amount of newly added data, improving the controllability of the price generation process, and solving the problems of inconsistent price standards and heavy workload in manual calculation.
