Obviously, the accompanying drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other accompanying drawings can be obtained based on these accompanying drawings without paying creative work.

[0059] Figure 1 This is a flow chart of the enterprise business travel reservation cost control management system and method in Example 1.

[0060] Figure 2 This is a decision diagram of the enterprise business travel reservation cost control management system and method in Example 1. DETAILED DESCRIPTION

[0061] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0062] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0063] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0064] Example 1, reference Figure 1 and Figure 2 , which is the first embodiment of the present invention, and provides a method for controlling the cost of corporate business travel reservations, including the following steps:

[0065] S1. Employees submit business trip applications to their superiors. Business trip applications include key elements such as travel time, location, and purpose. This information is the basis for subsequent processing and ensures the completeness and clarity of the application.

[0066] S1.2. The superior supervisor reviews the details of the business trip application and decides whether to approve it based on the company's policy and actual situation.

[0067] Supervisor's approval is a key link in the business trip process, ensuring the necessity and rationality of the business trip.

[0068] If the supervisor believes that the business trip application is unreasonable or does not comply with company regulations, he or she may reject the application and give the reason for the rejection. If the supervisor approves the business trip application, the next step is taken.

[0069] S1.3. After approval by the superior, the blockchain network automatically generates a block corresponding to the employee on business trip and adds the block to the blockchain network. The block contains the business trip application information and approval status.

[0070] The block corresponding to the employee on business trip is a unique block generated according to the employee's business trip application information, and the block contains key information of the business trip application (such as employee ID, business trip time, location, purpose, etc.), and approval status (approved).

[0071] The generated blocks are added to the blockchain network, ensuring that all business trip application information is recorded in an unalterable environment.

[0072] When block generation is detected, the smart contract is automatically activated.

[0073] Further explanation: Through blockchain technology, all business trip application information is recorded in an unalterable block, ensuring the security and transparency of the data. This is of great significance for preventing data tampering and ensuring the authenticity and integrity of financial records. The automatic activation of smart contracts greatly reduces the need for manual intervention and improves management efficiency.

[0074] S2. After the smart contract is started, the budget situation of the employee’s department is read, including department information, budget balance and historical records.

[0075] Get department information. The smart contract obtains the information of the employee’s department from the system database, including the department name and the total department budget.

[0076] Query the budget balance. The smart contract queries the department’s current budget balance, which is the total amount of funds available to the department.

[0077] Read historical records. The smart contract reads the department's budget usage over the past period of time for comprehensive analysis.

[0078] S2.1. Based on the department budget situation, the smart contract automatically generates budget allocation information according to the employee's level and business trip location information.

[0079] The smart contract determines the basic budget amount according to the employee's level (such as ordinary employee, manager, director).

[0080] The smart contract adjusts the budget amount according to the location of the business trip. For example, the accommodation and transportation costs in first-tier cities and second-tier cities may be quite different.

[0081] S2.2. After the budget allocation information is generated, the smart contract will automatically add this information to the block corresponding to the employee on business trip in the blockchain. The smart contract adds this budget information to the previously generated business trip application block to ensure that all relevant information is in the same block. All information in the block (including business trip application information, approval status, budget allocation information) is eventually written into the blockchain network to ensure data security and immutability.

[0082] It is further explained that the budget allocation information is automatically generated through smart contracts, which can ensure the accuracy and rationality of budget allocation. Smart contracts take into account multiple factors such as employee level and business trip location, avoiding subjective errors and omissions that may exist in the traditional manual budget allocation process. In addition, all budget information is recorded in the blockchain, which improves the transparency of budget management.

[0083] S3. The smart contract automatically starts the booking process based on the business trip application and budget allocation information.

[0084] The smart contract generates a booking request based on the information in the business trip application (such as travel time and location); the booking request contains the employee's necessary information, such as personal information, travel time and location, so that hotels and airlines can provide suitable booking options.

[0085] S3.1. The smart contract sends a booking request to the hotel and airline through the API interface. The API interface allows the smart contract to communicate with external service providers, send booking requests and receive booking results.

[0086] S3.2. Hotels and airlines provide eligible booking options based on the information in the booking request (such as check-in time, room type, etc.). These options usually include detailed information such as price, room type, flight time, etc.

[0087] Hotels and airlines return booking results to smart contracts through API interfaces. The returned results contain specific booking information, such as hotel name, room type, check-in time, flight number, departure time, etc.

[0088] S3.3. After receiving the booking result, the smart contract verifies whether the booking result meets the requirements according to the conditions in the booking request.

[0089] After verification, the smart contract records the booking result in the block corresponding to the traveling employee on the blockchain.

[0090] S3.4. The smart contract sends the booking information to the employee’s personal workstation, where the employee can view the booking details.

[0091] The reservation information includes hotel name, check-in time, flight number, departure time, etc.

[0092] The employee checks the booking details on his / her personal workstation and confirms the booking.

[0093] Further explanation: By automatically initiating the booking process through smart contracts, the need for human intervention is reduced and booking efficiency is improved. From generating a booking request to sending the request and receiving the booking result, the entire process is highly automated, reducing human errors and delays.

[0094] S4. The historical data refers to the expense records of the company's past business trips, which include the actual expenses incurred during each business trip, such as accommodation expenses, transportation expenses, food expenses, etc.

[0095] Historical data provides valuable information for enterprises, which can help them make more reasonable budget allocation in future business trip management;

[0096] S4.1. In order to predict the additional expenses during business trips, the system establishes a prediction model based on historical data. The model uses the time distance decay method to perform weighted processing on historical business trip records.

[0097] According to the importance of historical business trip records, a weight factor w is assigned to each business trip. i The weight factor may be determined based on factors such as the importance of the business trip and the level of the business trip personnel.

[0098] For each historical business trip record, calculate the time distance decay factor Among them, d i is the number of days between the i-th business trip and the current business trip, and α is the attenuation coefficient. The closer the time distance of the business trip record, the greater the attenuation factor.

[0099] Calculate the sum of all historical business trip records after time decay. The expression is:

[0100]

[0101] Where D represents the comprehensive impact value of all historical business trip records after time decay.

[0102] Suppose we have the following historical business trip records and their time distances:

[0103] First business trip: time distance d1 = 5 days;

[0104] Second business trip: time distance d1 = 10 days;

[0105] The third business trip: time distance d1 = 20 days;

[0106] Assuming the decay coefficient α = 0.1, we can calculate the time distance decay factor of each historical record:

[0107] First business trip: e -0.1×5 =e -0.5 ≈0.607;

[0108] Second business trip: e -0.1×10 =e -1 ≈0.368;

[0109] The third business trip: e -0.1×20 =e -2 ≈0.135;

[0110] Calculate the total time distance decay D = e -0.5 +e -1 +e -2 ≈0.607+0.368+0.135=1.110.

[0111] Integrating the above contents, the additional expenses during the business trip are predicted as follows:

[0112]

[0113] in, represents the predicted additional expenses during the business trip, w i represents the weight factor of the i-th business trip, F i represents the actual cost of the i-th business trip, d i represents the number of days between the i-th business trip and the current business trip, α represents the attenuation coefficient, n represents the number of historical business trip records, and D represents the comprehensive impact value of all historical business trip records after time decay.

[0114] S4.2. Smart contract obtains additional fees for prediction from prediction model

[0115] The additional costs to be expected Compare with the original budget to determine whether budget allocation needs to be adjusted

[0116] If the predicted additional costs If the original budget is exceeded, the smart contract automatically adjusts the budget allocation and adds additional budget to ensure that there is no budget shortage during the business trip.

[0117] If the predicted additional costs If it is lower than the original budget, the original budget will be kept unchanged or reduced appropriately to avoid wasting resources.

[0118] Further explanation: By building a forecasting model based on historical data, it is possible to more accurately predict the additional expenses during business trips. This method takes into account the impact of time and distance on expenses, ensuring the rationality of the forecast results. Smart contracts automatically adjust budget allocations based on the forecast results, avoiding problems caused by insufficient budgets.

[0119] S5. Employees use mobile applications (such as mobile phone apps) to take photos or scan expense receipts (such as accommodation invoices, catering invoices, transportation tickets, etc.) generated during business trips.

[0120] S5.1. Use OCR (Optical Character Recognition) technology to identify key information in expense documents, such as amount, date, item category, etc. The OCR engine parses the text in the image and converts it into a structured data format.

[0121] S5.2. Generate an expense record based on the extracted expense information, including the expense amount, date, consumption type, etc.

[0122] Expense records also include employee ID and other necessary identity verification information.

[0123] The expense records will be added to the block corresponding to the traveling employee on the blockchain, ensuring the security and immutability of all expense information.

[0124] S5.3. When the smart contract detects a new expense record, it automatically adds it to the block of the corresponding employee on business trip. Each expense record is timestamped to ensure the order and time consistency of the expense records.

[0125] Smart contracts update fee records in real time, ensuring that all fee information is up to date.

[0126] S5.4. Employees shall submit an expense reimbursement list after completing a business trip. The list shall include details of all expenses that need to be reimbursed.

[0127] The expense details in the list correspond to the expense receipts uploaded previously to ensure that all expenses are traceable.

[0128] Record expense reimbursement list information on the blockchain.

[0129] S5.5. Smart contracts verify the consistency of expense records and expense reimbursement list information, ensuring that all expense details are supported by corresponding expense receipts.

[0130] The smart contract automatically triggers the reimbursement process based on the verified expense information. The reimbursement process includes expense review, approval and other links.

[0131] The smart contract automatically transfers the reimbursement amount to the employee’s bank account or other designated account, and the reimbursement information is added to the block corresponding to the traveling employee on the blockchain.

[0132] Further explanation: Uploading expense documents through mobile applications and automatically recognizing the bill information through OCR technology has greatly improved the efficiency of expense management. Employees do not need to manually enter expense information, reducing manual errors and workload.

[0133] S6. The smart contract obtains all transaction records related to the business trip from the blockchain, including but not limited to business trip application, approval status, budget allocation, booking information, expense records, reimbursement information, etc.

[0134] According to preset financial policies, laws and regulations, each transaction record is checked one by one to see if it meets the requirements.

[0135] The inspection content includes but is not limited to whether the cost exceeds the budget, whether the reimbursement complies with regulations, whether the reservation is reasonable, etc. The smart contract records the inspection results on the blockchain.

[0136] When the smart contract detects any violation, the alarm mechanism is automatically triggered.

[0137] The alarm mechanism includes measures such as sending warning information and freezing illegal accounts; at the same time, the smart contract sends relevant information of the illegal behavior to relevant departments, such as the financial department, legal department, etc.

[0138] S6.1. After the employee's business trip is completed, the smart contract collects all records related to the business trip from the blockchain, integrates the collected information, and generates a business trip report.

[0139] S6.2. Use statistical analysis to analyze business trip reports.

[0140] Calculate the deviation between the actual cost and the forecast cost during the business trip. The expression is:

[0141]

[0142] Among them, E dev represents the cost deviation mean, E j represents the actual cost of item j, P j represents the j-th predicted expense, and m represents the number of expense items.

[0143] Calculate the ratio between actual expenses during the business trip and the budget allocation, the expression is:

[0144]

[0145] Among them, B eff represents the budget execution rate, C k represents the actual cost of item k, B k represents the kth budget allocation; l represents the number of budget allocations.

[0146] Calculate whether the reimbursement amount meets the budget limit. The expression is:

[0147]

[0148] Among them, R com represents the reimbursement compliance rate, R p represents the reimbursement amount of item p, S p represents the budget limit of item p, and q represents the number of reimbursement items.

[0149] The above three indicators are combined to obtain the final business trip evaluation result, which is expressed as follows:

[0150]

[0151] Among them, Assessment pred Indicates the final business trip evaluation result.

[0152] The value range of the final business trip evaluation result is [0,1]. A value close to 1 indicates that the business trip expenses are well controlled, the budget execution rate is high, and the reimbursement compliance rate is high; a value close to 0 indicates that the business trip expenses have a large deviation, the budget execution rate is low, and the reimbursement compliance rate is low.

[0153] S6.3. Make suggestions for improvement based on the business trip report and business trip evaluation results;

[0154] If the cost deviation is large, it is recommended to adjust the forecast model to improve the forecast accuracy;

[0155] If budget execution is poor, it is recommended to optimize the budget allocation strategy, such as adjusting budget allocation based on historical data;

[0156] If there are any irregularities in reimbursement, it is recommended to strengthen the review of the reimbursement process to ensure compliance;

[0157] If the booking process is not efficient, it is recommended to optimize the booking strategy, such as booking in advance and choosing more cost-effective hotels and flights.

[0158] Further explanation: through in-depth analysis of business trip reports, smart contracts can provide scientific evaluation results to help corporate management better understand the various indicators during business trips. Scientific evaluation results provide a solid foundation for formulating improvement suggestions.

[0159] S6.4. The smart contract stores the business trip report, business trip evaluation results and improvement suggestions together in the block corresponding to the business trip employee on the blockchain. At the same time, the smart contract sends the business trip evaluation results and improvement suggestions to the employee’s superior. The superior can view this information in a timely manner and take corresponding management measures.

[0160] Further explanation: Smart contracts automatically complete the generation of business trip reports, the generation of evaluation results, the proposal of improvement suggestions, and the storage and transmission of information, reducing the need for manual intervention and improving management efficiency. The automated process reduces the possibility of errors and delays. It also strengthens communication and feedback between superiors and subordinates. Supervisors can understand the business trip situation in a timely manner and take corresponding management measures based on improvement suggestions, forming a closed-loop management.

[0176] Example 2, referring to Table 1, is the second example of the present invention. To further verify the technical solution of the present invention, experimental simulation data of the enterprise business travel reservation cost control management method is provided.

[0177] In order to evaluate the actual effect of the present invention in the management of corporate business travel reservation expenses, a three-month pilot test was conducted, and Company A was selected as the pilot unit. Before the pilot, Company A used traditional paper and email methods to manage the business trip application, reservation and reimbursement process. The following is a detailed description of the implementation process:

[0178] Business trip application module:

[0179] An employee of Company A submits a business trip application to his superior, and the application information includes the time, location, purpose, etc. of the business trip.

[0180] After approval by the superior, a block corresponding to the employee on business trip is generated and added to the blockchain network, and the smart contract is automatically started.

[0181] Block generation and smart contract startup module:

[0182] When the block is generated, the smart contract starts running, automatically reading the budget situation of the employee's department and automatically generating budget allocation information based on the employee's level and business trip location information.

[0183] Budget allocation information is automatically added to the block in the blockchain corresponding to the traveling employee.

[0184] Budget checking and allocation module:

[0185] The smart contract checks the budget situation of the employee department and generates budget allocation information, which includes various budgets such as transportation expenses, accommodation expenses, and food expenses.

[0186] Budget allocation information is recorded on the blockchain, and the smart contract automatically triggers the booking process.

[0187] Booking and information push module:

[0188] The smart contract automatically initiates the booking process based on the business trip application and budget allocation information, and sends a booking request to the hotel and airline API interfaces.

[0189] Hotels and airlines provide eligible booking options based on the booking request and return the booking results to the smart contract through the API interface.

[0190] The smart contract verifies the booking result and adds it to the block on the blockchain corresponding to the traveling employee.

[0191] The smart contract sends the booking information to the employee’s personal workstation, where the employee can view and confirm the booking details.

[0192] Cost forecasting module:

[0193] Build a forecasting model based on historical data to predict additional expenses during business trips.

[0194] Expense Recording Module:

[0195] During business trips, employees upload expense receipts through mobile applications, identify the bill information through OCR technology, and record the expense information on the blockchain.

[0196] The smart contract automatically records the uploaded expense information into the block corresponding to the traveling employee on the blockchain and updates the expense record in real time.

[0197] Expense Reimbursement Module:

[0198] After the employee completes the business trip, he / she submits the expense reimbursement list, and the expense reimbursement list information will be recorded in the blockchain.

[0199] The smart contract automatically triggers the reimbursement process based on the expense records and expense reimbursement list information, and automatically transfers the reimbursement amount to the employee account.

[0200] The smart contract adds the reimbursement information to the block on the blockchain corresponding to the traveling employee.

[0201] Transaction record audit module:

[0202] Smart contracts automatically detect whether all transaction records comply with the company's internal financial policies and external laws and regulations, and record the detection results on the blockchain.

[0203] When a violation is detected, the smart contract will automatically trigger the alarm mechanism and notify the relevant departments for processing.

[0204] Business trip report generation and analysis module:

[0205] After the employee's business trip is completed, the smart contract will summarize all relevant records and generate a business trip report.

[0206] The smart contract uses statistical analysis to analyze business trip reports, generate business trip evaluation results, and make improvement suggestions based on the business trip reports and business trip evaluation results.

[0207] After completing the analysis and improvement of the business trip report, the smart contract will store the business trip report and the business trip evaluation results together in the block corresponding to the business trip employee on the blockchain.

[0208] At the same time, the smart contract will send the business trip evaluation results and improvement suggestions to the superior supervisor.

[0209] The details are shown in Table 1 below:

[0220] This shows that the error rate of the present invention in budget allocation is significantly reduced.

[0221] For example, the budget allocation error of Zhang San using the prior art is 10%, while the budget allocation error of Zhang San using the present invention is 7%.

[0222] How close the predicted additional costs are to the actual additional costs:

[0223] In terms of predicting the additional costs, the predicted value of the present invention is very close to the actual value.

[0224] Zhang San's predicted additional cost is 300 yuan, and the actual additional cost is 280 yuan;

[0225] Li Si's predicted additional cost is 400 yuan, and the actual additional cost is 350 yuan;

[0226] Wang Wu's predicted additional cost is 500 yuan, and the actual additional cost is 420 yuan;

[0227] Zhao Liu predicted additional costs of 600 yuan, and the actual additional costs were 550 yuan.

[0228] This shows that the present invention has a high accuracy in predicting the additional costs.

[0229] Relationship between total budget and additional costs:

[0230] It can be seen from the table data that as the total budget increases, the predicted additional costs and the actual additional costs also increase accordingly, but the predicted additional costs of the present invention are always close to the actual additional costs.

[0231] This shows that the prediction capability of the present invention maintains consistent accuracy under different budget sizes.
