[0002] In the context of the Internet of Things era, big data strongly supports resource sharing. Some scientific research instruments, experimental equipment and other resources can be shared. Usually, units that own experimental instruments are used as instrument service units, and the information of their experimental instruments is entered into the shared instrument reservation platform. Users who do not own experimental instruments make reservations for experimental instruments on the shared instrument reservation platform. For example, the Chinese invention patent with application number 202110166263.X discloses a management method and system for shared instruments. Users can use online reservations to make reservations for shared instruments. The procedures are simple and the process is relatively easy.

[0003] For service units registered in the shared instrument reservation platform, they need to purchase the corresponding instruments for reservation users to make reservations and generate corresponding reservation income. Currently, service units usually judge whether to purchase the corresponding instruments based on human experience, which makes it impossible to achieve reasonable purchase of experimental instruments at service units.

[0059] In a fourth aspect, an embodiment of this specification provides a computer storage medium, wherein the computer storage medium stores a plurality of instructions, wherein the instructions are suitable for being loaded by a processor and executing the steps described in the first aspect of the above embodiment.

[0060] The beneficial effects brought by the technical solutions provided by some embodiments of this specification include at least:

[0061] Comprehensive purchase benefit evaluation information can be given for purchase requests, where the purchase benefit evaluation information includes the purchase benefits corresponding to purchasing different quantities of target instruments at different time points within a first preset period of time in the future. Based on the purchase benefit evaluation information of the purchase request, instrument purchase plans are recommended, thereby guiding the service units in the shared instrument reservation platform to make better instrument purchase operations.

[0062] When the target purchase price of the target instrument is greater than the theoretical purchase price of the target instrument, the evaluation result of not recommending purchase is directly output, thereby preventing the service unit from purchasing instruments that do not meet market price trends.

[0063] Based on the purchase quantity of preferred target instruments and the instrument storage space information of the target service unit corresponding to different time nodes in the first preset time period in the future, the instrument purchase plan is recommended. The instrument storage space information of the target service unit is comprehensively considered to make the instrument purchase plan recommendation more reasonable.

[0065] Based on the target purchase quantity, the target purchase price, the target instrument quantity corresponding to each of the multiple time periods within the second preset time period starting from the target time node within the first preset time period in the future, the number of reservations for the target instrument, and the number of target instrument usage requirements corresponding to each of the multiple time periods within the first preset time period before the end time of the second preset time period, and the reserved usage fee for the target instrument, the purchase benefit corresponding to the purchase of the target number of target instruments at the target time node is obtained. That is, a second preset time period is further set within the first preset time period, and the purchase benefits of purchase operations at different time nodes are calculated based on the data within the second preset time period, thereby ensuring the comparability between the purchase benefits corresponding to the purchase of different quantities of target instruments at different time nodes.

[0066] When determining the revenue time period, firstly, based on the preset ratio and the number of target instrument reservations corresponding to each of the multiple time periods within the second preset time, an upper limit value is provided, and the number of target instrument reservations corresponding to each of the multiple time periods within the second preset time is obtained to provide an upper limit adjustment value. Further, based on the number of target instrument reservations corresponding to each of the multiple time periods within the second preset time, the upper limit adjustment value is provided, and the total number of target instrument reservations corresponding to each of the multiple time periods within the second preset time, the revenue time period within the second preset time is determined. This makes the method of determining the revenue time period more reasonable. BRIEF DESCRIPTION OF THE DRAWINGS

[0072] The technical solutions in the embodiments of this specification will be described clearly and completely below in conjunction with the drawings in the embodiments of this specification.

[0073] The terms "first", "second", "third", etc. in the description and claims of this specification and the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally includes steps or units that are not listed, or optionally includes other steps or units inherent to these processes, methods, products or devices.

[0074] The following description provides examples and does not limit the scope, applicability or examples set forth in the claims. Changes may be made to the functions and arrangements of the elements described without departing from the scope of the present specification. Various processes or components may be appropriately omitted, substituted or added to each example. For example, the described method may be performed in an order different from the order described, and various steps may be added, omitted or combined. In addition, features described with respect to some examples may be combined in other examples.

[0075] Reference Figure 1 As shown, it is a schematic diagram of the environmental architecture of the implementation process of the instrument purchase duplication check and review method based on multi-time node benefit evaluation provided in one or more embodiments of this specification.

[0076] The implementation environment architecture of the instrument purchase duplication check and review method based on multi-time node benefit evaluation provided in one or more embodiments of this specification at least includes a server 101 and a client 102.

[0077] Among them, the client 102 can be a mobile phone, a personal computer, a tablet computer, an e-book reader, a device for information interaction based on VR (Virtual Reality), a vehicle terminal, an IoT (Internet of Things) device, a wearable smart device, a laptop computer, a desktop computer, etc.

[0078] The service unit needs to download an application that can open or run the shared instrument reservation platform on the client 102 in advance. The reservation user can enter a purchase request in the running interface of the application. The purchase request may include, but is not limited to, purchase instrument information and service unit information. Figure 1As shown. The equipment purchase information may include, but is not limited to, the target purchase price of the target equipment. The target purchase price may be understood as the actual price at which the service unit purchases the target equipment, that is, the supplier's quotation. The service unit information may include, but is not limited to, the unit location.

[0079] It should be noted that, in the actual application process, there should be multiple clients 102 corresponding to multiple service units in the implementation environment architecture. Figure 1 Only the client 102 of one service unit is shown as an example.

[0080] After the service end 101 receives the purchase request input by the service unit, it first obtains the target area range according to the unit location, that is, determines the area range for analysis. Further obtain target instrument quantity information and target instrument reservation information. The target instrument quantity information includes the number of target instruments corresponding to each of the multiple time periods within the target area within the first preset time period in the future. The target instrument reservation information includes the number of target instruments reserved and the reserved usage fee for the target instruments corresponding to each of the multiple time periods within the target area within the first preset time period in the future. Further, based on the purchase instrument information, the target instrument quantity information, and the target instrument reservation information, the purchase benefit evaluation information of the purchase request can be obtained. The purchase benefit evaluation information includes the purchase benefits corresponding to each of the purchases of different quantities of target instruments at different time nodes within the first preset time period in the future. Finally, based on the purchase benefit evaluation information of the purchase request, an instrument purchase plan recommendation can be made. Figure 1 As shown, the recommended purchase time and the recommended purchase quantity may be outputted but are not limited to.

[0081] Reference Figure 2 As shown, Figure 2 The flowchart of the instrument purchase duplication check and review method based on multi-time node benefit evaluation provided in an embodiment of this specification may at least include the following steps:

[0082] Step 202: Obtain a purchase request of a target service unit, wherein the purchase request includes purchase instrument information and service unit information, wherein the purchase instrument information includes a target purchase price of the target instrument, and the service unit information includes a unit location;

[0083] Step 204: Obtain the target area range based on the unit position;

[0084] Step 206, obtaining target instrument quantity information, wherein the target instrument quantity information includes the target instrument quantity corresponding to each of multiple time periods within a first preset time period in the target area;

[0085] Step 208, obtaining target instrument reservation information, wherein the target instrument reservation information includes the number of target instrument reservations corresponding to each of multiple time periods within a first preset time period in the target area and the target instrument reservation usage fee;

[0086] Step 210: Based on the purchase instrument information, the target instrument quantity information, and the target instrument reservation information, the purchase benefit evaluation information of the purchase request is obtained, wherein the purchase benefit evaluation information includes the purchase benefits corresponding to the purchase of different quantities of target instruments at different time nodes within a first preset time period in the future, wherein the time node is the start time of the time period;

[0087] Step 212: Recommend an instrument purchase plan based on the purchase benefit evaluation information of the purchase request.

[0088] It should be noted that the target instrument quantity information and target instrument reservation information can be obtained by prediction using a pre-trained prediction model. During the prediction process, only the historical instrument quantity information needs to be input into the prediction model to output the target instrument quantity information. The same is true for the target instrument reservation information.

[0089] That is, the target instrument quantity, target instrument reservation times, and target instrument reservation fees corresponding to each of the multiple time periods within the first preset time period in the future are all predicted based on the target instrument quantity information, target instrument reservation times, and target instrument reservation fees information under historical circumstances, without considering the purchasing operation factors of the target service unit.

[0090] It is understandable that even for the same target instrument, there may be multiple reservation usage fees. Therefore, the reservation usage fees for the target instruments corresponding to the above-mentioned different time periods can be understood as the average of the reservation usage fees.

[0091] It should also be noted that, for the reserved usage fees of the target instrument corresponding to multiple time periods within the first preset time period in the future, they can not only be predicted based on the historical reserved usage fee information of the target instrument and the above-mentioned prediction model, but can also be directly set manually based on the historical reserved usage fee information of the target instrument and human experience.

[0092] The instrument purchase duplicate checking and evaluation method based on multi-time node benefit evaluation provided in multiple embodiments of the present specification can provide comprehensive purchase benefit evaluation information for purchase requests, wherein the purchase benefit evaluation information includes the purchase benefits corresponding to purchasing different quantities of target instruments at different time nodes within a first preset period of time in the future, and based on the purchase benefit evaluation information of the purchase request, recommends instrument purchase plans, thereby guiding the service units in the shared instrument reservation platform to make better instrument purchase operations.

[0093] In one embodiment of the present specification, when the target purchase price of the target instrument is greater than the theoretical purchase price of the target instrument, the evaluation result of not recommending purchase is directly output, and the step of obtaining the purchase request of the target service unit is returned;

[0094] When the target purchase price of the target instrument is not greater than the theoretical purchase price of the target instrument, executing the step of obtaining the target area range based on the unit position;

[0095] Before obtaining the purchase benefit evaluation information of the purchase request based on the purchase instrument information, the target instrument quantity information, and the target instrument reservation information, the method further includes:

[0096] Based on the target instrument quantities corresponding to multiple time periods within the target area within a first preset time period in the future, determine and execute the step of directly outputting the evaluation result of not recommending purchase or the step of obtaining the purchase benefit evaluation information of the purchase request based on the purchase instrument information, target instrument quantity information, and target instrument reservation information.

[0097] It should be noted that the theoretical purchase price is the normal price of the target instrument. For example, an ammeter should be in the hundreds or thousands of yuan range, and usually not as high as ten thousand yuan. Therefore, in this embodiment, when the target purchase price of the target instrument is greater than the theoretical purchase price of the target instrument, a non-purchase recommendation result is directly output, thereby preventing the service unit from purchasing instruments that do not meet the market price.

[0098] It is understandable that, because the storage space of the equipment of the service unit is limited, the equipment storage space information of the target service unit should be comprehensively considered when recommending the purchase plan. Therefore, in one embodiment of the present specification, the purchase benefit evaluation information of the purchase request is used to recommend the equipment purchase plan, including:

[0099] Based on the purchase benefit evaluation information of the purchase request, obtaining the purchase quantity of the preferred target instruments corresponding to different time nodes within a first preset time period in the future;

[0100] The instrument storage space information of the target service unit is obtained, and based on the preferred target instrument purchase quantities corresponding to different time nodes within the first preset time period in the future and the instrument storage space information of the target service unit, an instrument purchase plan is recommended.

[0101] In one embodiment of the present specification, the service unit information further includes target instrument demand information, and the target instrument demand information includes the number of target instrument usage demands corresponding to each of a plurality of time periods within a first preset time period in the future;

[0102] The acquisition of the purchase benefit evaluation information of the purchase request based on the purchase instrument information, the target instrument quantity information, and the target instrument reservation information includes:

[0103] Based on the purchase instrument information, the target instrument demand information, the target instrument quantity information, and the target instrument reservation information, a purchase evaluation result of the purchase request is obtained.

[0104] It is understandable that when a service unit initiates a purchase request for a target instrument, it usually begins to have a demand for the target instrument. Therefore, in this embodiment, when providing comprehensive purchase benefit evaluation information for a purchase request, the service unit's own target instrument demand information is considered (Note: the target instrument demand information is actively input by the service unit, and can be but not limited to once a day, once a week, once a month, etc.). Specifically, the costs incurred by the service unit's own target instrument demand during the period between initiating the purchase request and formally purchasing the target instrument are regarded as costs, and the costs incurred by the service unit's own target instrument demand after the formal purchase of the target instrument are regarded as income, so as to make the purchase benefit evaluation information more reasonable (which will be explained in the corresponding embodiments below).

[0105] In one embodiment of the present specification, the acquisition of purchase benefits corresponding to the purchase of a corresponding number of target instruments at a corresponding time node includes:

[0106] Step 2102: the purchase time of the corresponding target instrument is regarded as the target time, and the purchase quantity of the corresponding target instrument is regarded as the target purchase quantity;

[0107] Step 2104: Based on the target instrument quantity information and the target instrument reservation information, obtain the target instrument quantity and the target instrument reservation times corresponding to each of the multiple time periods within the second preset time period within the first preset time period in the future with the target time node as the starting time;

[0108] Step 2106: Based on the target instrument demand information and the target instrument reservation information, obtain the target instrument usage demand times and the target instrument reservation usage fees corresponding to each of the multiple time periods within the first preset time period and before the end time of the second preset time period;

[0109] Step 2108: Based on the target purchase quantity, the target purchase price, the target instrument quantity corresponding to each of the multiple time periods within the second preset time period in the future with the target time node as the starting time, the number of target instrument reservations, and the number of target instrument usage requests corresponding to each of the multiple time periods within the first preset time period in the future and before the end time of the second preset time period, and the reserved usage fee of the target instrument, obtain the purchase benefit corresponding to purchasing the target quantity of target instruments at the target time node.

[0110] In this embodiment, the purchase benefit corresponding to the target number of target instruments purchased at the target time node is obtained based on the target purchase quantity, the target purchase price, the number of target instruments corresponding to each of the multiple time periods within the second preset time period starting from the target time node within the first preset time period in the future, the number of target instrument reservations, and the number of target instrument usage requirements corresponding to each of the multiple time periods within the first preset time period before the end time of the second preset time period, and the reserved use fee of the target instrument. That is, a second preset time period is further set within the first preset time period, and the purchase benefits of purchase operations at different time nodes are calculated based on the data within the second preset time period, thereby ensuring the comparability between the purchase benefits corresponding to different numbers of target instruments purchased at different time nodes.

[0111] For ease of understanding, the following is explained using a specific example, and the following multiple embodiments are also expanded using this example:

[0112] Assume that the first preset time period is 1 year, the target time node is the 21st day, the second preset time period is 30 days, and each time period is 10 days.

[0113] Then the number of target instruments and the number of reservations of the target instruments corresponding to the multiple time periods in the second preset time period with the target time node as the starting time within the first preset time period in the future are respectively:

[0114] The number of target instruments and the number of reservations for target instruments corresponding to the 21st to 30th day;

[0115] The number of target instruments and the number of reservations for target instruments corresponding to the 31st to 40th day;

[0116] The number of target instruments and the number of reservations for target instruments corresponding to the 41st to 50th days.

[0117] The target instrument usage demand times and the target instrument reserved usage fees corresponding to the multiple time periods within the first preset time period in the future and before the end time of the second preset time period are respectively:

[0118] The number of target instrument usage requests and the target instrument reservation fee corresponding to the 1st to 10th day;

[0119] The number of target instrument usage requests and the target instrument reservation fee corresponding to the 11th to 20th day;

[0120] The number of target instrument usage requests and the target instrument reservation fee corresponding to the 21st to 30th day;

[0121] The number of target instrument usage requests and the target instrument reservation fee corresponding to the 31st to 40th day;

[0122] The number of target instrument usage requests and the target instrument reservation fee corresponding to the 41st to 50th days.

[0123] In one embodiment of the present specification, the acquisition benefit corresponding to the target number of target instruments purchased at the target time node is obtained based on the target purchase quantity, the target purchase price, the target instrument quantity corresponding to each of the multiple time periods within the second preset time period starting at the target time node within the first preset time period in the future, the number of target instrument reservations, and the target instrument usage demand number corresponding to each of the multiple time periods within the first preset time period in the future and before the end time of the second preset time period, and the target instrument reservation usage fee, including:

[0124] Step 21082: based on the number of target instrument usage demands and the target instrument reserved usage fees corresponding to each of the multiple time periods in the first preset time period before the end time of the second preset time period, obtain the number of target instrument usage demands and the target instrument reserved usage fees corresponding to each of the multiple time periods in the first preset time period before the start time of the second preset time period;

[0125] Continuing with the above example, in this embodiment, the number of target instrument usage requirements and the target instrument reserved usage fee corresponding to each of the multiple time periods within the first preset time period in the future and before the start time of the second preset time period are obtained, namely:

[0126] The number of target instrument usage requests and the target instrument reservation fee corresponding to the 1st to 10th day;

[0127] The number of target instrument usage requests and the target instrument reservation fee corresponding to the 11th to 20th day.

[0128] Step 21084: Obtain a first cost based on the number of target instrument usage requests and the target instrument reserved usage fee corresponding to each of the multiple time periods within the first preset time period in the future and before the start time of the second preset time period;

[0129] Because the service unit could have directly purchased the target instrument after initiating the purchase request, however, in multiple embodiments of this specification, corresponding purchase benefit analysis was performed for different purchase time nodes. Therefore, the expenses incurred by the service unit's own target instrument needs during the period between initiating the purchase request and formally purchasing the target instrument are regarded as costs, so as to make the purchase benefit evaluation information more reasonable.

[0130] Step 21086: Based on the target purchase quantity and the target purchase price, obtain the second cost.

[0131] Step 21088: based on the target instrument usage demand counts corresponding to the multiple time periods in the first preset time period before the end time of the second preset time period, obtain the target instrument usage demand counts corresponding to the multiple time periods in the second preset time period;

[0132] Continuing with the above example, in this embodiment, the number of target device usage requirements corresponding to each of the multiple time periods within the second preset time length is obtained, namely, respectively:

[0133] The number of target instrument usage requirements corresponding to the 21st to 30th day;

[0134] The number of target instrument usage requirements corresponding to the 31st to 40th day;

[0135] The target instrument usage requirements from day 41 to day 50.

[0136] Step 210810: Acquire the purchase income based on the target purchase quantity and the number of target instrument usage requirements, the target instrument quantity, the number of target instrument reservations, and the target instrument reservation usage fee corresponding to each of the multiple time periods within the second preset time period;

[0137] The costs incurred by the service unit's own demand for the target instrument after the target instrument is officially purchased will be regarded as income to make the acquisition benefit evaluation information more reasonable.

[0138] Step 210812: Based on the first cost, the second cost, and the purchase benefit, obtain the purchase benefit corresponding to purchasing the target purchase quantity of target instruments at the target time node. The purchase benefit may be calculated by, but is not limited to,: purchase benefit = purchase benefit - (first cost + second cost).

[0139] In one embodiment of the present specification, the acquisition of the purchase income based on the target purchase quantity and the number of target instrument usage requirements, the target instrument quantity, the number of target instrument reservations, and the target instrument reservation usage fee corresponding to each of the multiple time periods within the second preset time period includes:

[0140] Step A, obtaining the upper limit of the number of reservations for a single target instrument in a single time period;

[0141] Continuing with the above example, the upper limit of the number of reservations for a single target instrument in a single time period in this embodiment can be understood as the upper limit of the number of reservations for a target instrument within 10 days, for example, a maximum of 10 reservations can be made within 10 days.

[0142] Step B, based on the target purchase quantity and the upper limit of the number of reservations for a single target instrument in a single time period, obtaining an increase in the number of reservations for the target instrument in a single time period;

[0143] Continuing with the above example, assuming the target purchase quantity is 5 units, the increase in the number of target instrument reservations in a single time period can be, but is not limited to, 5*10 times = 50 times. This step is a calculation for the target purchase quantity in the service unit's procurement operation.

[0144] Step C, based on the upper limit of the number of reservations for a single target instrument in a single time period and the number of target instruments corresponding to each of the multiple time periods within the second preset time period, obtaining the upper limit of the number of reservations for the target instruments corresponding to each of the multiple time periods within the second preset time period;

[0145] Continuing with the above example, assuming that the number of target instruments in a certain time period is 30, the upper limit of the number of target instrument reservations corresponding to the time period is 30*10 times = 300 times. This step is a calculation based on the number of target instruments already in the time period (i.e., the number of target instruments purchased by the target service unit is not considered).

[0146] Step D, based on the number of target instrument usage demands and the number of target instrument reservations corresponding to the multiple time periods within the second preset time, obtain the total number of target instrument reservations corresponding to the multiple time periods within the second preset time;

[0147] It can be understood that the total number of reservations for the target instrument corresponding to each time period should be the sum of the number of target instrument usage requests in the time period and the number of target instrument reservations in the time period.

[0148] Step E: Acquisition income is obtained based on the increase value provided by the number of reservations for the target instrument in a single time period, the upper limit value provided by the number of reservations for the target instrument corresponding to each of the multiple time periods within the second preset time period, the total number of reservations for the target instrument corresponding to each of the multiple time periods within the second preset time period, and the reservation usage fee for the target instrument corresponding to each of the multiple time periods within the second preset time period.

[0149] It can be understood that within the second preset time period, the reservation service that cannot be provided by the existing target instrument can be provided by the target instrument purchased by the target service unit, so this part of the service provision can be regarded as purchase income.

[0150] In one embodiment of the present specification, the acquisition income is obtained based on providing an increase value based on the number of target instrument reservations in a single time period, providing an upper limit value based on the number of target instrument reservations corresponding to each of the multiple time periods within the second preset time period, the total number of target instrument reservations corresponding to each of the multiple time periods within the second preset time period, and the reserved usage fee of the target instrument corresponding to each of the multiple time periods within the second preset time period, including:

[0151] Determine the profit time period within the second preset time period based on providing an upper limit value for the number of target instrument reservations corresponding to each of the multiple time periods within the second preset time period and the total number of target instrument reservations corresponding to each of the multiple time periods within the second preset time period;

[0152] Based on the reserved usage fees of the target instrument corresponding to each of the multiple time periods within the second preset time period, the reserved usage fees of the target instrument corresponding to the revenue time period are obtained;

[0153] The purchase income is obtained based on the added value provided by the number of target instrument reservations in a single time period, the total number of target instrument reservations corresponding to the profit time period, the upper limit value provided by the number of target instrument reservations corresponding to the profit time period, and the reserved usage fee of the target instrument corresponding to the profit time period.

[0154] It can be understood that the time period within the second preset time period when the existing target instruments cannot meet the total number of target instrument reservations can be regarded as the profit time period (for example: the time period when the upper limit value of the number of target instrument reservations is ≤ the total number of target instrument reservations is regarded as the profit time period). Therefore, based on the added value provided by the number of target instrument reservations in a single time period, the total number of target instrument reservations corresponding to the profit time period, the upper limit value of the number of target instrument reservations corresponding to the profit time period, and the reservation fee for the target instrument corresponding to the profit time period, the purchase income can be obtained.

[0155] In one embodiment of the present specification, the step of providing an upper limit value based on the number of target instrument reservations corresponding to each of the multiple time periods within the second preset time period and the total number of target instrument reservations corresponding to each of the multiple time periods within the second preset time period, and determining the revenue time period within the second preset time period includes:

[0156] Get the preset ratio;

[0157] Based on the preset ratio and the upper limit value provided by the target instrument reservation times corresponding to each of the multiple time periods within the second preset duration, the upper limit adjustment value of the target instrument reservation times corresponding to each of the multiple time periods within the second preset duration is obtained;

[0158] Based on providing an upper limit adjustment value based on the number of target instrument reservations corresponding to each of the multiple time periods within the second preset time length and the total number of target instrument reservations corresponding to each of the multiple time periods within the second preset time length, determining a revenue time period within the second preset time length;

[0159] In this embodiment, when determining the revenue time period, firstly, based on the preset ratio, the number of target instrument reservations corresponding to each of the multiple time periods within the second preset duration is provided with an upper limit value, and the number of target instrument reservations corresponding to each of the multiple time periods within the second preset duration is obtained to provide an upper limit adjustment value. Further, based on the number of target instrument reservations corresponding to each of the multiple time periods within the second preset duration, the upper limit adjustment value is provided, and the total number of target instrument reservations corresponding to each of the multiple time periods within the second preset duration, the revenue time period within the second preset duration is determined. This makes the method of determining the revenue time period more reasonable.

[0160] It is understandable that, assuming that the upper limit of the number of target instrument reservations for existing target instruments within a certain period of time is 100 times, the total number of target instrument reservations is also 100 times, and no new target instruments are added at this time, then all target instrument reservation demands will be allocated to the existing target instruments. If a new target instrument is added at this time, part of the reservation demand will be diverted to the newly added target instrument (Note: It may be a natural diversion, or it may be because the new target instrument has a better use effect).

[0161] Therefore, when confirming the revenue time period, the time period in which the upper limit value of the number of target instrument reservations is ≤ the total number of target instrument reservations cannot be simply regarded as the revenue time period. Instead, it is necessary to first determine the upper limit value of the number of target instrument reservations corresponding to each of the multiple time periods within the second preset time based on the preset ratio, and obtain the upper limit adjustment value of the number of target instrument reservations corresponding to each of the multiple time periods within the second preset time. For example, the upper limit value of the number of target instrument reservations provided is 100 times * the preset ratio 9 / 10, and the upper limit adjustment value of the number of target instrument reservations provided is 90 times. Subsequently, based on the upper limit adjustment value of the number of target instrument reservations corresponding to each of the multiple time periods within the second preset time, and the total number of target instrument reservations corresponding to each of the multiple time periods within the second preset time, the revenue time period within the second preset time is determined. For example: the time period in which the upper limit adjustment value of the number of target instrument reservations provided is ≤ the total number of target instrument reservations is regarded as the revenue time period.

[0162] Therefore, in this embodiment, the acquisition income is obtained based on the increase value provided by the number of reservations of the target instrument in a single time period, the total number of reservations of the target instrument corresponding to the profit time period, the upper limit value provided by the number of reservations of the target instrument corresponding to the profit time period, and the reserved usage fee of the target instrument corresponding to the profit time period, including:

[0163] The purchase income is obtained by providing an increased value based on the number of target instrument reservations in a single time period, the total number of target instrument reservations corresponding to the profit time period, the reserved usage fee of the target instrument corresponding to the profit time period, and the upper limit adjustment value of the number of target instrument reservations corresponding to the profit time period obtained by the preset ratio and the total number of target instrument reservations corresponding to the profit time period. Specifically, it can be:

[0164] Based on the total number of target instrument reservations corresponding to the revenue time period and the number of target instrument reservations corresponding to the revenue time period, an upper limit adjustment value is provided to obtain the difference in the number of reservations corresponding to the revenue time period;

[0165] The purchase income is obtained by providing the added value based on the number of reservations for the target instrument in a single time period, the difference in the number of reservations corresponding to the profit time period, and the reservation fee for the target instrument corresponding to the profit time period.
