[0012] To make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in combination with the embodiments and the drawings. Herein, the illustrative embodiments of the present invention and their descriptions are used to explain the present invention, but do not limit the present invention;

[0013] Specific Embodiment 1: A pricing method for harvester maintenance services includes:

[0014] Step 1: Obtain the labor cost of the equipment to be repaired and the total cost of repairing the accessories of the equipment to be repaired, and set the maintenance profit rate and the fixed service fee; determine the basic maintenance service price of the equipment to be repaired according to the labor cost of the equipment to be repaired, the total cost of repairing the accessories of the equipment to be repaired, the maintenance profit rate and the fixed service fee;

[0015] Step 2: Obtain the current market maintenance supply-demand ratio, the current maintenance busy index ratio and the current key accessory price index ratio, set the sensitivity coefficient, and calculate the price dynamic adjustment factor according to the current market maintenance supply-demand ratio, the current maintenance busy index ratio, the current key accessory price index ratio and the sensitivity coefficient;

[0016] Step 3: Compare the current market maintenance supply-demand ratio with the set threshold. If the current market maintenance supply-demand ratio is less than the set threshold, go to Step 4; if the current market maintenance supply-demand ratio is not less than the set threshold, go to Step 5;

[0017] Step 4: Update the labor cost of the equipment to be repaired to obtain the updated labor cost, and recalculate the basic repair service price of the equipment to be repaired based on the updated labor cost, the total cost of repairing the accessories of the equipment to be repaired, the repair profit margin, and the fixed service fee to obtain the updated basic repair service price of the equipment to be repaired; and multiply the updated basic repair service price of the equipment to be repaired by the dynamic adjustment factor to obtain the final pricing of the repair service for the equipment to be repaired;

[0018] Step 5: Multiply the basic repair service price of the equipment to be repaired by the dynamic adjustment factor to obtain the final pricing of the repair service for the equipment to be repaired.

[0019] Specifically, a pricing method for the repair service of a harvester first obtains the labor cost and the total cost of repairing the accessories of the equipment to be repaired, and determines the basic repair service price of the equipment to be repaired based on the obtained labor cost and the total cost of repairing the accessories; updates the labor cost according to the current market repair supply-demand ratio and further updates the basic repair service price of the equipment to be repaired, sets a dynamic adjustment factor for the equipment repair price, and multiplies the updated basic repair service price of the equipment to be repaired by the dynamic adjustment factor to obtain the final pricing of the repair service for the equipment to be repaired; the dynamic adjustment factor for the price enables the final pricing of the equipment repair service to be dynamically adjusted according to the market supply and demand, ensuring the rationality and flexibility of the repair pricing.

[0020] Furthermore, the method for obtaining the labor cost of the equipment to be repaired includes: obtaining the basic parameters of the equipment to be repaired and the unit price of the labor cost, calculating the repair working hours of the equipment to be repaired based on the basic parameters of the equipment, and multiplying the repair working hours by the unit price of the labor cost to obtain the labor cost;

[0021] The basic parameters of the equipment include: basic repair working hours, working hour growth coefficient, service life of the equipment to be repaired, cumulative working hours of the equipment to be repaired, and equipment condition index of the equipment to be repaired;

[0022] The method for calculating the repair working hours of the equipment to be repaired based on the basic parameters of the equipment is:

[0023] where T is the repair working hours, T0 is the basic repair working hours, α is the working hour growth coefficient, A is the service life of the equipment to be repaired, H is the cumulative working hours of the equipment to be repaired, I is the equipment condition index of the equipment to be repaired, and I ∈ [0, 1].

[0024] Specifically, the basic repair working hours are one unit per hour, the working hour growth coefficient is taken as 0.5, and the cumulative working hours of the equipment to be repaired are in hours; when the value of the equipment condition index is 1, it indicates the best state of the equipment; the labor cost is represented by L, and L = C L ×T, C L is the unit price of the labor cost, with the unit of yuan / hour; the repair working hours of the equipment to be repaired are determined according to the specific usage of the equipment to be repaired, and the accuracy is high.

[0025] Further, the method for obtaining the total repair cost of the parts of the equipment to be repaired includes: The equipment to be repaired includes N key parts. Obtain the market price of each key part, the recommended maximum service life of each key part, and the recommended maximum working hours of each key part;

[0026] Calculate the replacement probability of each key part according to the market price of each key part, the recommended maximum service life of each key part, and the recommended maximum working hours of each part, and calculate the repair cost of each part according to the market price of each key part and the corresponding replacement probability; Sum up the repair costs of the N key parts to obtain the total repair cost of the parts;

[0027] The method for calculating the replacement probability of each key part according to the market price of each key part, the recommended maximum service life of each key part, and the recommended maximum working hours of each part is as follows:

[0028] where r i is the replacement probability of the i-th key part, i ∈ N; R i is the market price of the i-th key part, is the recommended maximum service life of the i-th key part, is the recommended maximum working hours of the i-th key part;

[0029] The method for calculating the repair cost of each part according to the market price of each key part and the corresponding replacement probability is as follows: where is the repair cost of the i-th key part;

[0030] The method for summing up the repair costs of the N key parts to obtain the total repair cost of the parts is as follows: where P P is the total repair cost of the parts of the equipment to be repaired.

[0031] Further, the method for determining the basic repair service price of the equipment to be repaired according to the labor cost of the equipment to be repaired, the total repair cost of the parts of the equipment to be repaired, the repair profit rate, and the fixed service cost is: P base =(L + P P )(1 + β)+γ;

[0032] where P base is the basic repair service price of the equipment to be repaired, L is the labor cost; P p is the total repair cost of the parts of the equipment to be repaired, β is the repair profit rate, γ is the fixed service cost.

[0033] Further, the method for obtaining the current market repair supply-demand ratio, the current repair busyness index ratio, and the current critical parts price index ratio includes:

[0034] Obtain the current daily repair demand, the historical average daily repair demand, the current number of available repair technicians, the number of repair requests on the current day, the total current market price of all critical parts, and the historical average value of the total market price of all critical parts;

[0035] Take the ratio of the current number of available repair technicians to the number of repair requests on the current day as the current market repair supply-demand ratio;

[0036] Take the ratio of the current daily repair demand to the historical average daily repair demand as the current repair busyness index ratio;

[0037] Take the ratio of the total current market price of all critical parts to the historical average value of the total market price of all critical parts as the current critical parts price index ratio.

[0038] Further, the sensitivity coefficients include a first sensitivity coefficient, a second sensitivity coefficient, and a third sensitivity coefficient;

[0039] The method for calculating the price dynamic adjustment factor based on the current market repair supply-demand ratio, the current repair busyness index ratio, the current critical parts price index ratio, and the sensitivity coefficients is as follows:

[0040]

[0041] Where θ is the price dynamic adjustment factor, α1 is the first sensitivity coefficient, α2 is the second sensitivity coefficient, α3 is the third sensitivity coefficient, D is the current daily repair demand, D0 is the historical average daily repair demand, N tech is the current number of available repair technicians, R daily is the number of repair requests on the current day, P parts is the total current market price of all critical parts, is the historical average value of the total market price of all critical parts.

[0042] Specifically, to make the price better reflect the current market and service status, a price dynamic adjustment factor is introduced, and this factor has been calibrated and updated in actual operation through machine learning or dynamic optimization algorithms.

[0043] Further, the method for updating the calculated labor cost to obtain the updated labor cost is: L N = L(1 + m); where L N is the updated labor cost, and m is the percentage increase in price;

[0044] The method for recalculating the basic maintenance service price of the equipment to be repaired according to the updated labor cost, total maintenance cost of the accessories of the equipment to be repaired, maintenance profit margin and fixed service fee to obtain the updated basic maintenance service price of the equipment to be repaired is: P base_N =(L N +P P )(1 + β)+γ; where P base_N is the updated basic maintenance service price of the equipment to be repaired.

[0045] Specifically, dynamically adjust the labor cost according to market demand to optimize the pricing strategy to ensure the rationality and flexibility of maintenance prices;

[0046] In step four, the method for multiplying the updated basic maintenance service price of the equipment to be repaired by the dynamic adjustment factor to obtain the final pricing of the maintenance service of the equipment to be repaired is: P final =P base_N ×θ, where P final is the final pricing of the maintenance service of the equipment to be repaired;

[0047] In step five, the method for multiplying the basic maintenance service price of the equipment to be repaired by the dynamic adjustment factor to obtain the final pricing of the maintenance service of the equipment to be repaired is: P final =P base ×θ, where P base is the basic maintenance service price of the equipment to be repaired.

[0048] Furthermore, set the threshold value to 1.

[0049] Specifically, when the current market maintenance supply-demand ratio is less than 1, it indicates that the current number of available maintenance technicians is less than the number of maintenance requests on the same day, and the maintenance technicians are in short supply.

[0050] Example: Specifically, taking a harvester used by an agricultural enterprise for 5 years as an example, the cumulative working hours of the equipment is 2,000 hours, and the equipment condition index is 0.85; this method first calculates the basic maintenance man-hours according to the equipment usage years, working hours and equipment condition index, and determines the basic labor cost in combination with the unit price of labor cost. Subsequently, by statistically analyzing the replacement historical data of key accessories, calculating the replacement probability of each key accessory using the current state of the equipment and the recommended replacement standard of key accessories, and obtaining the total maintenance cost of the accessories accordingly. On this basis, adding the set profit margin and fixed service fee to obtain the basic maintenance service price. Then, the system real-time collects the daily maintenance demand data, the supply situation of maintenance technicians and the current market prices of key accessories, generates a price dynamic adjustment factor through a pre-trained dynamic adjustment algorithm, and corrects the basic maintenance service price. Finally, this method provides the final pricing of the maintenance service for the harvester, and the final pricing of the maintenance service effectively reflects the actual maintenance cost of the equipment and market changes, providing strong support for the enterprise to achieve scientific and reasonable maintenance cost control.
