[0074] Reference Figure 1 A flowchart of a business travel service decision method based on a multi-modal model provided by an embodiment of the present application is shown in FIG. 1. In the embodiment, the business travel service decision method based on a multi-modal model includes:

[0075] S1, receiving a business travel application instruction based on a pre-constructed business travel service platform, wherein the business travel service platform includes a decision unit, an approval unit, a travel unit and a reimbursement unit.

[0076] Specifically, the business travel service platform refers to a digital platform providing business travel services for enterprises. In the embodiments of the present application, the business travel service platform includes but is not limited to a decision unit, an approval unit, a travel unit and a reimbursement unit. In addition, the business travel service platform can also include a lodging unit, etc. In the embodiments of the present application, the focus is on the services and applications provided by the business travel service platform for enterprises in terms of travel, and other functions are not limited.

[0077] Further, the decision unit is a unit for formulating a ticket booking decision according to the needs of the applicant, the approval unit is a unit for approving the business travel preference decision in the enterprise, the travel unit is a unit for providing travel services, such as booking a ticket, calling a taxi, etc., the reimbursement unit is a unit for paying, generating an invoice and making a reimbursement detail for the applicant, the accommodation unit is a unit for providing accommodation services for the applicant, such as booking a hotel, etc. For specific unit applications, please refer to the subsequent embodiments.

[0078] It can be understood that the business travel application instruction is an instruction initiated by the applicant when the applicant needs to travel, and when the business travel service platform receives the business travel application instruction, the business travel preference strategy is formulated for the applicant, the approval is realized, the travel service is provided, the invoice is automatically generated, and the whole process of the business travel of the applicant is facilitated.

[0079] S2, identifying the applicant identity based on the business travel application instruction, and confirming the business travel preference decision based on the applicant identity and the decision unit.

[0080] It should be noted that the applicant identity is the identity information of the applicant, including but not limited to name, ID number, position in the enterprise, etc., for uniquely identifying the applicant.

[0081] Specifically, the business travel preference decision is confirmed based on the applicant identity and the decision unit, including:

[0082] Based on the applicant identity, business travel basic data is obtained, wherein the business travel basic data includes: departure place, destination, travel start and end time, travel person and business travel nature;

[0083] According to the business travel basic data, a target travel rule is retrieved from a pre-constructed business travel rule library, a plurality of departure dates are obtained according to the travel start and end time;

[0084] From the plurality of departure dates, a departure date is sequentially extracted, and the following operations are performed on the extracted departure date:

[0085] Based on the extracted departure date, a plurality of travel booking platforms are accessed by the travel unit, a plurality of initial travel data sets are filtered according to the plurality of travel booking platforms, wherein the initial travel data set corresponds to the travel booking platform one by one, and the initial travel data set includes a plurality of unit travel data;

[0086] If there is an initial travel data set that meets the preset direct travel standard in the plurality of initial travel data sets, the initial travel data set that meets the preset direct travel standard is summarized to obtain a direct travel data set, and the business travel preference decision is confirmed based on the target travel rule, the direct travel data set and the decision unit;

[0087] If there is no initial travel data group meeting the preset direct travel standard in the plurality of initial travel data groups, the plurality of initial travel data groups are confirmed as transit travel data sets, and the business travel preference decision is confirmed based on the target travel rule, the transit travel data sets and the decision unit.

[0088] It should be noted that the business travel basic data is obtained based on the applicant identity, including: obtaining a basic data questionnaire, sending the basic data questionnaire to the initiation end of the business travel application instruction, receiving the filled basic data questionnaire sent by the initiation end of the business travel application instruction, obtaining a complete questionnaire, and identifying business travel basic data based on the complete questionnaire. The basic data questionnaire is a survey questionnaire designed by human, and the basic data questionnaire includes a plurality of tabs, including but not limited to tabs composed of departure place, destination, travel start and end time, travel person and business travel nature, etc. When the applicant completes the selection of each tab in the basic data questionnaire through the plurality of tabs, the business travel service platform can receive the filled basic data questionnaire sent by the initiation end of the business travel application instruction. Here, the filled basic data questionnaire of the applicant is the complete questionnaire. Further, there are various existing technologies for identifying business travel basic data based on the complete questionnaire, including but not limited to OCR text recognition, image recognition, etc., so this will not be repeated here.

[0089] It can be understood that the applicant only fills in one departure day in the travel start and end time, and based on the departure day filled in by the applicant in the travel start and end time, the application selects the day before and the day after the departure day filled in the travel start and end time as the alternative date, so that a plurality of departure days can be obtained according to the travel start and end time.

[0090] It should be noted that the departure place is the end point of the journey in a business travel process of the applicant, the destination is the starting point of the journey in a business travel process of the applicant, the travel start and end time is the time period between the departure time and the return time in a business travel process of the applicant, the travel person is the applicant, and the business travel nature is the nature of the business travel of the applicant, including but not limited to meetings, expatriation, research, etc.

[0091] Further, the business travel rule library is a business travel standard formulated by an enterprise for different positions, different destinations, different business travel natures, etc., used to limit business travel preference decisions, such as limitations on travel modes, limitations on accommodation hotels, limitations on daily subsidies of an applicant, etc. The present application does not limit the complete content of the business travel rule library, but at least includes limitations on travel modes. Therefore, the target travel rule is a business travel standard that an applicant should comply with when traveling according to the business travel basic data from the business travel rule library. For example, the position of the applicant is M, the destination is P, and the business travel nature is a meeting. Therefore, the target travel rule indicates that when traveling, if taking a high-speed rail, first-class seats and second-class seats can be booked, if taking an airplane, business class and economy class can be booked, and if taking a train, soft sleep, hard sleep, soft seat, and hard seat, etc. can be booked. Also, for example, the transfer time in the booked travel ticket cannot exceed two hours, etc. Further, the target travel rule can also include rules such as only allowing to take direct travel vehicles, etc., which will not be described here.

[0092] It should be noted that the departure date is the departure time of the applicant in a business travel process, the travel ticket booking platform is an externally connected unit for booking tickets, such as a small program or app that can directly book tickets, such as Ctrip, 12306, etc. The initial travel data set is all ticket data that meets the business travel basic data that can be retrieved on a travel ticket booking platform. Therefore, the number of the plurality of initial travel data sets is equal to the number of the plurality of travel ticket booking platforms. The unit travel data is a single trip information retrieved on a travel ticket booking platform, such as a destination being c place, a departure place being b place, and a departure date being June 3. Therefore, an initial travel data set can be retrieved on a travel ticket booking platform. For example, one unit travel data in the initial travel data set can be [high-speed rail, departure time, arrival time, travel time, destination, departure place, train class number, business class remaining tickets, business class ticket price, first-class seat remaining tickets, first-class seat ticket price, second-class seat remaining tickets, and second-class seat ticket price]. Details will not be described here. It should be noted that the present application is for the convenience of example and concise writing, and the specific numbers of the unit travel data and subsequent embodiments are not limited, such as the specific number of business class remaining tickets, etc.

[0093] Further, the preset direct travel standard indicates that if the ticket (or ticket) corresponding to the unit travel data is selected, no transfer is required from the departure place to the destination, and it is considered to meet the preset direct travel standard, otherwise, it is considered not to meet the preset direct travel standard.

[0094] It should be noted that in order to improve the convenience of the applicant when traveling, reduce the difficulty of booking tickets, save travel costs and reduce the workload of reimbursement, when the present invention executes business travel service decisions for the applicant, if there is an initial travel data group that meets the preset direct travel standard among multiple initial travel data groups, the step of confirming the business travel preference decision based on the target travel rules, direct travel data set and decision unit will be implemented first. When there is no initial travel data group that meets the preset direct travel standard among multiple initial travel data groups, it means that there is no ticket or air ticket that can directly reach the destination from the departure point without transit in the multiple initial travel data groups. Therefore, the direct travel data set includes multiple direct travel data, and the direct travel data is a unit of travel data in the initial travel data group that meets the preset direct travel standard.

[0095] It should also be noted that while this disclosure details the departure date in business travel preference decisions, it does not specifically address the return date. This is because once the return date is determined, travel decisions are similar to those for the departure date and can be handled using the same decision-making methods as for the departure date. Furthermore, in actual applications, it is possible that the return date cannot be determined. In such cases, the return date is not included in the business travel preference decision. This disclosure will not further elaborate on this point.

[0096] Specifically, the business travel preference decision is determined based on the target travel rules, the direct travel data set, and the decision unit, including:

[0097] Based on the decision-making unit, multiple compliant direct travel data that meet the target travel rules are screened from the direct travel data set, and the remaining ticket data of the same flight are merged for the multiple compliant direct travel data to obtain multiple data of the same flight;

[0098] Extract the same-shift data from multiple same-shift data sets in sequence, and perform the following operations on the extracted same-shift data:

[0099] Identifying a seat type set in the same-flight data, and performing a same-flight type clustering operation on the same-flight data based on the seat type set to obtain a plurality of same-flight seat data, wherein the seat type set includes a plurality of seat types, and the same-flight seat data includes a plurality of seat fare data of the same seat type, and the seat fare data corresponds one-to-one to the travel booking platform;

[0100] Extracting the same seat data from multiple same seat data in sequence, identifying the lowest-priced seat fare data among the extracted same seat data, obtaining target seat data, and constructing preferred remaining ticket data based on the target seat data;

[0101] Summarize the optimal remaining ticket data and obtain the optimal strategy for the same flight corresponding to the data of the same flight;

[0102] The same-class optimization strategies are aggregated to obtain a same-class optimization strategy set, the same-class optimization strategy set is classified according to a preset travel category to obtain a plurality of classified data groups, and each classified data group in the plurality of classified data groups is arranged in order from early to late according to a travel time of a class corresponding to the classified data group to obtain a plurality of classified optimization strategy sequences.

[0103] The plurality of classified optimization strategy sequences are sent to a pre-constructed business travel application instruction initiation end, and a preference selection from the business travel application instruction initiation end is received to obtain a business travel preference decision.

[0104] It should be noted that the direct travel data is not only the travel data from the departure date from the departure place to the destination, but also meets the preset direct travel standard. However, when making a business travel preference decision, the target travel rule also needs to be met, so the direct travel data set also needs to be further filtered. For example, the direct travel data is

high-speed rail, departure time, arrival time, time spent, destination, departure place, train class number, business seat remaining ticket, business seat ticket price, first-class seat remaining ticket, first-class seat ticket price, second-class seat remaining ticket, second-class seat ticket price

high-speed rail, departure time, arrival time, time spent, destination, departure place, train class number, first-class seat remaining ticket, first-class seat ticket price, second-class seat remaining ticket, second-class seat ticket price

[0105] Further, the same-class remaining ticket data merging operation is to merge the same-class direct travel data in the plurality of direct travel data, and delete the data that does not exist in the remaining tickets in the merged direct travel data. The class is a journey of a public transport tool running according to a fixed schedule.

[0106] Exemplary, with

high-speed rail, departure time, arrival time, experience time, destination, departure place, train number, business class ticket, business class ticket price, first class ticket, first class ticket price, second class ticket, second class ticket price

[0107] The first same class data: flight number, travel booking platform A-business class ticket-business class ticket price-economy class ticket-economy class ticket price, travel booking platform B-business class ticket-business class ticket price-economy class ticket-economy class ticket price, travel booking platform C-business class ticket-business class ticket price-economy class ticket-economy class ticket price;

[0108] The second same class data: high-speed rail number, travel booking platform A-soft sleeper ticket-soft sleeper ticket price-hard seat ticket-hard seat ticket price, travel booking platform B-soft sleeper ticket-soft sleeper ticket price-hard seat ticket-hard seat ticket price, travel booking platform C-soft sleeper ticket-soft sleeper ticket price-hard seat ticket-hard seat ticket price.

[0109] Further, in the first same-class data, the trip ticket booking platform A-business class remaining tickets-business class ticket price-economy class remaining tickets-economy class ticket price are data retrieved from the trip ticket booking platform A, and so on, which will not be described here. In the first same-class data, the business class remaining tickets and the economy class remaining tickets corresponding to the trip ticket booking platform A, the trip ticket booking platform B and the trip ticket booking platform C are completely same, because the number of remaining tickets is determined according to the actual remaining seats of the flight, which is irrelevant to the platform, while the business class ticket price and the economy class ticket price corresponding to different trip ticket booking platforms are different, so that in order to save the cost, the same-class data needs to be processed, so as to filter out the tickets with lower cost for the seat type in different trip ticket booking platforms, which will be described in subsequent embodiments.

[0110] Further, the seat type set is a set composed of all seat types in the same-class data, for example, in the same-class data, there are only first class seats and second class seats, so the seat type set includes two seat types, and the two seat types are first class seats and second class seats. Further, the same seat type clustering operation is to store the data with the same seat type in the same-class data in a same seat data.

[0111] Further, taking the first same-class data as an example, the seat type set in the first same-class data is identified, that is,

business class

economy class

[0112]

Business class: trip ticket booking platform A-business class ticket price, trip ticket booking platform B-business class ticket price, trip ticket booking platform C-business class ticket price

[0113]

Economy class: trip ticket booking platform A-economy class ticket price, trip ticket booking platform B-economy class ticket price, trip ticket booking platform C-economy class ticket price

[0114] Further, in the same seat data,

trip ticket booking platform A-business class ticket price

trip ticket booking platform B-business class ticket price

trip ticket booking platform C-business class ticket price

[0115] Furthermore, identifying the lowest-priced seat fare data among the extracted same-seat data to obtain the target seat data means: finding the lowest-priced seat fare data from the extracted same-seat data, and determining the lowest-priced seat fare data as the target seat data. For example, if the extracted same-seat data is: [Business Class: Travel Booking Platform A - Business Class Fare, Travel Booking Platform B - Business Class Fare, Travel Booking Platform C - Business Class Fare], and among the three seat fare data, [Travel Booking Platform B - Business Class Fare] is the lowest-priced seat fare data, then [Travel Booking Platform B - Business Class Fare] is determined as the target seat data.

[0116] Specifically, the preferred remaining ticket data is all the data of the ticket corresponding to the target seat data. For example, after confirming that the target seat data is in [Travel Ticket Booking Platform B-Business Class Fare], the data corresponding to the target seat data, such as [Flight, Departure Time, Arrival Time, Elapsed Time, Destination, Origin, Flight Number], is retrieved and merged with the target seat data. The resulting data is the preferred remaining ticket data. Then, when the applicant expects to take the flight number and travel business class from the departure point to the destination on the departure date, the ticket corresponding to the preferred remaining ticket data will be booked for the applicant first. This allows the applicant to order lower-cost tickets from different travel ticket booking platforms while meeting the applicant's travel needs, saving corporate costs.

[0117] It should also be noted that if there are different travel booking platforms with the same ticket prices, for example, the business class fares in [Travel Booking Platform B-Business Class Fares] and [Travel Booking Platform C-Business Class Fares] are the same, then the target seat data includes both [Travel Booking Platform B-Business Class Fares] and [Travel Booking Platform C-Business Class Fares], so the preferred remaining ticket data includes two unit preferred data, and the preferred remaining ticket data is still used to construct the same-flight preferred strategy. The specific difference is that the multiple classification preferred strategy sequences are displayed at the initiator of the business travel application instruction, and the two unit preferred data included in the preferred remaining ticket data will be displayed at the same time for the applicant to choose.

[0118] Further, the same-class preference strategy is a set of multiple preferred ticket data. In the same class, different seat types can correspond to a target seat data, for example: the same-class preference strategy is

high-speed train class 1000, travel booking platform B - second-class seat price, travel booking platform C - first-class seat price

travel booking platform B - second-class seat price

travel booking platform C - first-class seat price

[0119] For example, if the current classification data group is high-speed rail, the existing first classification data

departure time: 8:00, high-speed train class 1000, travel booking platform B - second-class seat price, travel booking platform C - first-class seat price

departure time: 9:00, high-speed train class 1005, travel booking platform C - second-class seat price, travel booking platform C - first-class seat price

departure time: 6:00, high-speed train class 1008, travel booking platform B - second-class seat price, travel booking platform C - first-class seat price

[0120] Further, the multiple classification preference strategy sequences are sent to the initiator of the business travel application instruction, the multiple classification preference strategy sequences are displayed on the initiator of the business travel application instruction by using a pre-constructed visual display method, and the business travel preference decision satisfying the preferences of the applicant is obtained by receiving the preferences selected by the applicant. The preference selection is the desired travel decision selected by the applicant from the multiple classification preference strategy sequences on the initiator of the business travel application instruction. The visual display method can be realized by various existing technologies, which will not be described here.

[0121] Specifically, the business travel preference decision is confirmed based on the target travel rule, the transit travel data set and the decision unit, which includes:

[0122] The transit travel data is extracted from the transit travel data set in turn, and multiple unit direct data in the transit travel data are identified;

[0123] The plurality of unit direct data is used to obtain a plurality of unit direct preferred strategies, and the plurality of unit direct preferred strategies is used to obtain a preferred ticketing strategy corresponding to the transit travel data;

[0124] The preferred ticketing strategies are summarized, the transit preferred strategy sequence is obtained based on the summarized preferred ticketing strategies, the transit preferred strategy sequence is sent to the initiator of the business travel application instruction, and the preference selection from the initiator of the business travel application instruction is received to obtain the business travel preference decision.

[0125] It should be noted that the transit travel data set is similar to the direct travel data set, and the difference is that the tickets corresponding to the transit travel data in the transit travel data set need to pass through the transit to realize the business travel from the departure place to the destination.

[0126] Further, the transit travel data is data including the whole process from the departure place to the destination, for example, when the transit travel data represents that from the departure place to the destination, the transit is needed, then the transit travel data should include the unit direct data

first trip: departure place, transit place

second trip: transit place, destination

[0127] Specifically, the operation of obtaining a plurality of unit direct preferred strategies based on a plurality of unit direct data is similar to the operation method of obtaining the same class preferred strategy set based on the direct travel data set in the foregoing of the present application, and can achieve the same effect. The unit direct preferred strategy is similar to the same class preferred strategy, has similar meaning, and achieves similar effect, and will not be repeated here. The preferred ticketing strategy is the result of combining a plurality of unit direct preferred strategies corresponding to the transit travel data. For example, if a preferred ticketing strategy includes a first trip and a second trip, there is a unit direct preferred strategy for the first trip, and there is also a unit direct preferred strategy for the second trip.

[0128] Further, the process of obtaining the transit preferred ticket strategy sequence based on the aggregated preferred ticket strategy comprises: arranging the preferred ticket strategy in the order from the first leg of the transit data according to the departure time, and the obtained arranged sequence is the transit preferred ticket strategy sequence. The method of sending the transit preferred ticket strategy sequence to the initiator of the pre-constructed business travel application instruction and receiving the preference selection from the initiator of the business travel application instruction to obtain the business travel preference decision is similar to the method of sending the plurality of classified preferred strategy sequences to the initiator of the pre-constructed business travel application instruction and receiving the preference selection from the initiator of the business travel application instruction to obtain the business travel preference decision, and can achieve the same effect, which will not be described here.

[0129] S3, according to the approval unit confirming that the business travel preference decision corresponds to the approval process framework, if the approval is confirmed based on the approval process framework and the business travel preference decision, the initial travel booking project is obtained based on the business travel preference decision and the travel unit, the initial project booking operation is performed according to the initial travel booking project and the reimbursement unit, and the no-advance payment consolidated invoice is obtained after confirming that the initial project booking operation is completed.

[0130] It should be noted that the initial travel booking project is the project that needs to be booked in the business travel preference decision, for example, the high-speed rail that the applicant needs to take for business travel. It should be noted that when performing the initial project booking operation, the projects that need to be booked (accommodation, travel, conference tickets, etc.) are all booked, and when confirming that the initial project booking operation is completed, if the applicant has completed the booking project, an invoice and a travel itinerary will be generated for each completed project. After merging the generated invoice and travel itinerary, a no-advance payment consolidated invoice can be obtained. Optionally, the no-advance payment consolidated invoice can be in XML format or a pdf file. It should also be noted that when performing the initial project booking operation, the applicant does not need to pay in advance, but the enterprise can directly pay through the reimbursement unit. Optionally, the enterprise can directly pay through the reimbursement unit, which can be paid by the business travel service platform or by the enterprise reserving funds, which is not limited by the present application. In summary, the present application can reduce the complexity of the applicant's reimbursement procedures during business travel.

[0131] Specifically, the method of confirming the approval process framework corresponding to the business travel preference decision according to the approval unit comprises:

[0132] obtaining the applicant position of the applicant, querying the vertical position framework in the pre-constructed position architecture based on the applicant position, extracting a plurality of vertical review positions from the vertical position framework by using the pre-constructed approval file, and constructing a vertical approval sequence according to the position architecture and the plurality of vertical review positions, wherein the vertical approval sequence comprises a plurality of vertical approval nodes.

[0133] extracting a starting node from the longitudinal approval sequence to obtain a target node;

[0134] extracting an adjacent node based on the target node, constructing a longitudinal approval link based on the target node and the adjacent node, and returning the step of extracting the adjacent node based on the target node until the adjacent node is a preset end node to obtain a longitudinal approval chain, wherein the starting node is a first extracted longitudinal approval node located at an end of the longitudinal approval sequence, the adjacent node is a longitudinal approval node adjacent to the target node and lagging behind the target node in the longitudinal approval sequence, the end node is a last extracted longitudinal approval node located at an end of the longitudinal approval sequence, and the longitudinal approval chain includes a plurality of longitudinal approval nodes;

[0135] querying a financial position framework in a position architecture based on the applicant position, and constructing a financial approval chain based on the financial position framework;

[0136] constructing an approval initiation node based on the applicant position, and constructing an approval process framework according to the approval initiation node, the longitudinal approval chain, and the financial approval chain.

[0137] It should be noted that the applicant position is the position of the applicant in the company, for example, a technical department employee. Therefore, the longitudinal position framework is a position framework formed by gradually increasing the position based on the applicant position. For example, if the position architecture of the enterprise is as follows:

[0138]

[0139] For a technical department employee, the longitudinal position framework is

general manager-technical director-senior technical manager-technical supervisor-senior technical employee-technical department employee

[0140] Further, the approval document is a document for guiding the approval process, which is generally formulated by the enterprise where the applicant is located. The plurality of longitudinal review positions are the positions of a plurality of approvers who need to be approved in the approval document, and the positions of the plurality of approvers are located in the longitudinal position framework, for example, it is pointed out in the approval document that when a technical department employee needs business travel, the technical supervisor, the senior technical manager, and the technical director need to approve, and the plurality of longitudinal review positions are the technical supervisor, the senior technical manager, and the technical director. The longitudinal approval sequence is a sequence obtained by arranging the plurality of longitudinal review positions in the order of their positions in the position architecture. For example, the longitudinal approval sequence obtained by arranging the technical supervisor, the senior technical manager, and the technical director in the order of their positions in the position architecture is

technical supervisor, senior technical manager, technical director

[0141] Exemplarily, in the technical director, senior technical manager, technical director, the starting node can be the technical director or the technical director. If the technical director is confirmed as the starting node, it means that the technical director is the first extraction and is located at the end of the vertical approval sequence, so the technical director cannot be the starting node at this time. Taking the technical director as the target node, the senior technical manager is the vertical approval node adjacent to the target node and lagging behind the target node, so the senior technical manager is the adjacent node, and the vertical approval link is constructed between the target node and the adjacent node. When the vertical approval link is constructed between the target node (technical director) and the adjacent node (senior technical manager), the adjacent node is taken as the target node, and the step of extracting the adjacent node based on the target node is returned. The adjacent node (senior technical manager) is taken as the target node, and the adjacent node of the target node (senior technical manager) at this time, i.e. the technical director, is extracted, and the vertical approval link is constructed between the technical director and the senior technical manager. At this time, it is found that the adjacent node (technical director) is the last extraction in the vertical approval sequence and is located at the end of the vertical approval sequence, so the technical director is the terminal node. Therefore, the obtained vertical approval chain is

technical director-senior technical manager-technical director

technical director

senior technical manager

technical director

[0142] Further exemplarily, in the technical director, senior technical manager, technical director, the obtained vertical approval chain can also be

technical director-senior technical manager-technical director

[0143] It should be noted that the financial position framework is all the frameworks of the financial department. According to the previous examples in this paper, the financial position framework can be

general manager-financial director-financial director-financial clerk-financial assistant

general manager-financial director-financial director

[0144] Specifically, the approval process framework is constructed based on the applicant position, the approval initiation node, the vertical approval chain and the financial approval chain, which includes:

[0145] The first vertical approval end point and the second vertical approval end point of the vertical approval chain are extracted, and the applicant position points, the first vertical approval end position point and the second vertical approval end position point corresponding to the approval initiation node, the first vertical approval end point and the second vertical approval end point in the position architecture are located;

[0146] calculate a first vertical span between the applicant position point and the first vertical end position point, and calculate a second vertical span between the applicant position point and the second vertical end position point;

[0147] If the first vertical span is less than the second vertical span, the first vertical end point is confirmed as the vertical starting point, and the second vertical end point is confirmed as the vertical ending point, otherwise, the second vertical end point is confirmed as the vertical starting point, and the first vertical end point is confirmed as the vertical ending point;

[0148] obtain a financial approval starting point based on the financial approval chain;

[0149] Based on the vertical approval chain and the financial approval chain, after constructing the approval chain link between the approval initiation node and the vertical starting point, and constructing the approval chain link between the vertical ending point and the financial approval starting point, the approval process framework is obtained.

[0150] It should be noted that the first vertical end point and the second vertical end point are two vertical nodes located at the end points in the vertical approval chain, for example, in

Technical Supervisor-Senior Technical Manager-Technical Director

[0151] For example, the applicant position point, the first vertical end position point and the second vertical end position point corresponding to the approval initiation node, the first vertical end position point and the second vertical end position point are located in the position architecture as follows: using the position architecture in the foregoing example of the present application, if the approval initiation node is

Technical Department Employee

Technical Supervisor

Technical Director

Technical Department Employee

Technical Supervisor

Technical Director

[0152] It should be noted that the first longitudinal span is the span between the applicant position and the first longitudinal end position in the position architecture, for example, still using the position architecture described above in the example, if the applicant position is

technical staff

technical supervisor

[0153] It can be understood that when constructing the approval process framework, the application needs to report upward level by level from the approval initiation node according to the approval process guided in the approval document, therefore, first construct the longitudinal approval sequence according to the approval document and the position architecture, after confirming the longitudinal approval sequence, then construct the longitudinal approval chain that can join the approval of the corresponding responsible person in multiple longitudinal approval nodes according to the longitudinal approval sequence, when the longitudinal approval chain is constructed, the nodes that need to be approved in the longitudinal direction are basically constructed. At the same time, in a business trip, in addition to the approval of the applicant's leader, the financial aspect also needs to be approved, therefore, the application also constructs the financial approval chain.

[0154] It should be noted that the application considers that after all the longitudinal review nodes confirm that the business trip needs to be carried out, the financial related approval is carried out, therefore, the longitudinal approval chain and the financial approval chain are not two parallel links, but the applicant first passes the approval of the longitudinal approval chain, then passes the approval of the financial approval chain, and finally, the total responsible person is set at the end of the financial approval chain to approve, so as to complete the entire approval process, thereby preventing malicious public travel and other behaviors. The position architecture (such as the position architecture in the example described above), the longitudinal approval sequence and the financial approval sequence are usually two parallel links, therefore, the application cannot directly construct the entire approval process framework according to the order in the position architecture, but first constructs the longitudinal approval chain, and then constructs the financial approval chain.

[0155] Further, in the embodiment, the longitudinal approval chain is confirmed to be the longitudinal approval starting point, which is closer to the approval initiation node. In the previous step of the embodiment, the longitudinal approval chain is obtained according to the position architecture. When the longitudinal approval starting point and the longitudinal approval ending point are not confirmed, the longitudinal approval chain from the first longitudinal approval endpoint to the second longitudinal approval endpoint can be either a position ascending or a position descending. When the longitudinal approval starting point is confirmed and the approval chain link is constructed between the approval initiation node and the longitudinal approval starting point, the position is ascending from the approval initiation node to the longitudinal approval ending point, and thus the function of the step-by-step upward approval can be realized.

[0156] It should be noted that when the position of the applicant changes, the longitudinal approval chain also changes. For example, when the position of the applicant is the technical director as described in the previous example, there can be only one

general manager

[0157] Further, after the approval chain link is constructed between the longitudinal approval ending point and the financial approval starting point, a complete approval process framework can be constructed, for example:

technical staff-technical supervisor-senior technical manager-technical director-financial supervisor-financial director-general manager

[0158] It should be further noted that when there is only one longitudinal approval node in the longitudinal approval chain, the longitudinal approval node is both the first longitudinal approval endpoint and the second longitudinal approval endpoint. At this time, when the approval process framework is constructed, it is indicated that the applicant only needs one longitudinal approval node to complete the approval process in the longitudinal direction. For example, the position of the applicant is the technical director. According to the approval document, the technical director only needs to pass the general manager as a longitudinal approval node to complete the approval in the longitudinal direction. Therefore, the approval process framework is

technical director-general manager-financial supervisor-financial director-general manager

general manager-financial supervisor-financial director-general manager

[0159] Specifically, if the approval is confirmed to be passed based on the approval process framework and the business travel preference decision, the method further includes:

[0160] Based on the approval initiation node, the target approval node is extracted from the approval process framework in turn, and after confirming that the target approval node is in the preset unapproved state, the approval workflow is obtained based on the target approval node and the business travel preference decision, wherein the approval workflow includes: main audit information, business travel decision document, and approval process.

[0161] The main audit state is obtained based on the main audit information, and if the main audit state is in the preset online state, the approval workflow is sent to the pre-constructed main audit receiving end, otherwise, the approval workflow is sent to the pre-constructed deputy audit receiving end, and if a pre-constructed approval pass file is received from the main audit receiving end or the deputy audit receiving end, the target approval node is set to the passed state based on the approval pass file, and the step of extracting the target approval node from the approval process framework in turn is returned.

[0162] When it is confirmed that all target approval nodes in the approval process framework are in the passed state, it is confirmed that the approval is passed.

[0163] It should be noted that the target approval node is a node extracted from the approval process framework, the unapproved state is a state in which the target approval node has not been approved, and the target approval node is confirmed to be in the preset unapproved state to realize step-by-step upward approval according to the approval process framework and to confirm that the target approval node does not occur extraction error. The approval workflow is the target approval node, and the content in the business travel preference decision needs to be approved, and the approval workflow includes: main audit information, multiple deputy audit information, business travel decision document, and approval process. The approval pass file is a file sent by the main audit receiving end or the deputy audit receiving end when the approval is passed, and when the approval pass file is received from the main audit receiving end or the deputy audit receiving end, it means that the target approval node considers that the approval is passed.

[0164] Specifically, the business travel decision document is the content of the business travel preference decision that is mainly displayed in the target approval node, and all contents in the business travel preference decision are included in the business travel decision document. However, if the target approval node is a vertical audit node originally in a vertical approval chain, only the content of the departure place, the destination, and the business travel nature needs to be approved to determine whether to proceed with the business travel in the target approval node. Therefore, the business travel decision document in the target approval node mainly displays the content of the departure place, the destination, and the business travel nature. Further, the content in the initial trip reservation project, such as accommodation and travel mode, is more highlighted in the business travel decision document displayed to the financial audit node. Therefore, the approval workflow is different for different target approval nodes, and the targeted display of the approval workflow helps to reduce the workload of the target approval node and speed up the approval. Optionally, the highlighted display can be displayed by marking with different colors, which is not limited in the present application.

[0165] It can be understood that the main audit information is the information of the person in charge who needs to audit the approval workflow in the target approval node, including but not limited to: the information of the person in charge, the main audit state and the like. The main audit receiving end is the port of the person in charge corresponding to the main audit information for receiving and approving the approval workflow. The main audit state is information representing whether the person in charge corresponding to the main audit information is in a working state, for example, when the person in charge corresponding to the main audit information is on leave, the main audit state is not online, at this time the approval workflow needs to be sent to the pre-constructed deputy audit receiving end. The deputy audit receiving end is a port for temporarily receiving and approving the approval workflow by the person in charge of the target approval node when the person in charge corresponding to the main audit information cannot perform the approval.

[0166] Further, the approval process is the site of the target approval node in the approval process framework, which is used to represent the progress of the entire approval process and can be represented by text, charts and the like. The present application does not limit this. It should be noted that when the target approval node in the approval process framework is confirmed to be in a passed state, the approval is confirmed to be passed.

[0167] S4, receiving a real-time travel request from the applicant by using the travel unit, generating a real-time traffic invoice according to the real-time travel request and the reimbursement unit, and obtaining a real-time combined invoice by summarizing all real-time traffic invoices based on business travel preferences.

[0168] Specifically, the real-time travel request from the applicant is received by using the travel unit, a real-time traffic invoice is generated according to the real-time travel request and the reimbursement unit, and all real-time traffic invoices are summarized based on business travel preferences to obtain a real-time combined invoice. The method comprises the following steps:

[0169] Receiving a real-time travel request from the applicant, starting a pre-constructed real-time travel service system according to the real-time travel request, wherein the real-time travel service system is arranged in the travel unit, and the real-time travel service system comprises a plurality of short-distance units, and the plurality of short-distance units comprise a rental unit and a public transport unit;

[0170] Based on the analyzed real-time travel request, a target unit is started from the plurality of short-distance units in the real-time travel service system based on the analyzed real-time travel request, and a real-time traffic invoice is generated based on the reimbursement unit and the started target unit;

[0171] Based on the analyzed real-time travel request, a target unit is started from the plurality of short-distance units in the real-time travel service system based on the analyzed real-time travel request, and a real-time traffic invoice is generated based on the reimbursement unit and the started target unit;

[0172] Specifically, the real-time traffic invoice is generated based on the reimbursement unit and the started target unit, which comprises:

[0173] If the target unit is a taxi unit, a taxi destination and a taxi departure location are obtained, a real-time taxi trip request is generated based on the taxi destination and the taxi departure location, a real-time taxi trip order is generated based on the real-time taxi trip request, a taxi trip single and a taxi invoice are generated based on the real-time taxi trip order after the real-time taxi trip order is confirmed to be completed by platform payment, and a real-time traffic invoice single is obtained by summarizing the taxi trip single and the taxi invoice.

[0174] If the target unit is a bus unit, a bus trip code is called based on the bus unit, a bus trip single and a bus invoice are generated after the bus trip code is confirmed to be completed by platform payment, and a real-time traffic invoice single is obtained by summarizing the bus trip single and the bus invoice.

[0175] It should be noted that the real-time trip request is a request initiated by the applicant for short-distance travel in business travel, and the short-distance travel includes taking a taxi, taking a bus, etc. The real-time trip service system is a system for serving the short-distance travel of the applicant. The taxi unit is a unit for providing taxi service for the applicant, and the bus unit is a unit for providing public transportation service for the applicant, including buses, subways, etc.

[0176] It should be noted that the target unit can be obtained from the parsed real-time trip request by analyzing the real-time trip request. The business travel start-termination time is the start time and the termination time of the applicant in a business travel.

[0177] Specifically, the taxi destination and the taxi departure location are places where the applicant expects to arrive and places where the applicant expects to depart when taking the taxi during short-distance travel. The real-time taxi trip request is a request for calling a taxi initiated by the applicant through the taxi unit. The real-time taxi trip order is an order for short-distance travel generated by the taxi unit based on the real-time taxi trip request, including but not limited to order number, user information, driver information, trip information, etc. The order number is the number of this short-distance travel identified by a unique identifier. The user information includes but is not limited to the applicant's mobile phone number, name, etc. The driver information includes but is not limited to the driver's name, license plate number, etc. The trip information includes but is not limited to the pickup point, the drop-off point, the mileage, the time length, etc. The taxi trip single is a detailed list of the whole process of this short-distance travel after the real-time taxi trip order is completed, including but not limited to the order number, the user information, the driver information, the trip information, the expense details, etc. Optionally, the taxi trip single can be XML format data or table data, which is not limited here. The expense details include but are not limited to the starting price, the mileage fee, the final payment amount, etc. The taxi invoice is an invoice corresponding to the taxi trip single. The real-time traffic invoice single is a collection of the taxi trip single and the taxi invoice.

[0178] Further, the reimbursement unit based on the confirmation of the real-time rental travel order completion platform payment, including, when confirming the real-time rental travel order is completed, the reimbursement unit pays for the real-time rental travel order, when the payment is completed, then confirm the real-time rental travel order completion platform payment. The bus travel code is an out-of-town code that can be used to take buses, subways and other transportation tools. It is prior art and will not be described here. The bus travel code based on the confirmation of the completion of the bus travel platform payment is similar to the reimbursement unit based on the confirmation of the real-time rental travel order completion platform payment. The bus travel order and the bus invoice are similar to the rental travel order and the rental invoice, and can achieve the same effect. Here, it will not be described here.
