Description

Technical Field

[0001] This invention belongs to the field of visitor management technology, and in particular relates to a company visitor appointment management system and method. Background Technology

[0002] In many enterprises and institutions, there are management scenarios with strict control requirements for entering specific areas. These areas are usually defined as controlled areas, such as production workshops that need to maintain a specific level of cleanliness, laboratories involving sensitive information, and warehouses storing hazardous materials. These areas generally require external visitors to be accompanied by internal staff throughout their visit, and the accompanying person must hold the corresponding safety qualifications or access permits, such as an area access pass obtained through specialized training, a special equipment operation certificate, or emergency rescue qualifications. The accompanying person may also need to perform their own duties at the same time, resulting in a dynamically changing workload due to the limited time and energy available to them.

[0003] Currently, the most common method for visitor appointment management is through office automation systems or dedicated visitor registration systems, where visitors fill in their visit information, purpose of visit, and desired time in advance. The approval process usually flows to the person being visited, who then confirms and coordinates with a qualified colleague within their department to act as an escort, communicating the specific escort time manually via telephone, instant messaging, or other channels. Some management systems support preset lists of escorts, which can be manually selected by the front desk or visitor during the appointment process. However, the system itself does not verify whether the selected personnel hold the corresponding access qualifications for the area, nor can it perceive the actual workload of the personnel on that day. When multiple visitors need to be accompanied at the same time, or when a visitor's purpose of visit is of higher risk and requires more experienced personnel to follow up, the existing manual arrangement method is prone to problems such as omissions in qualification verification, uneven escort workload, and appointment time conflicts.

[0004] In summary, the main problem with existing technologies for handling visitor appointments in controlled areas is their inability to automatically coordinate and allocate suitable time slots and optimal companions based on the real-time qualifications, workload, and visitor risk of the accompanying personnel. This results in appointment processing relying heavily on manual coordination, making it difficult to guarantee the rationality and security of the allocation results. To address these issues, the following solutions are proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a company visitor appointment management system and method. By constructing a collaborative allocation method that integrates matching the qualifications of accompanying personnel, dynamic load assessment, and visitor risk adjustment, it can automatically determine suitable appointment time slots and accompanying personnel, and provide alternative time recommendations when no personnel are available. This solves the problem that existing visitor appointment methods rely on manual coordination and have difficulty balancing the qualifications of accompanying personnel and real-time load when dealing with the accompanying needs in controlled areas.

[0006] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0007] This invention relates to a company visitor appointment management system, comprising a front-end interaction unit and a back-end management unit. The front-end interaction unit receives appointment requests initiated by visitors, and the appointment request includes at least a visitor identifier, reason for visit, target location identifier, and desired visit time period. The back-end management unit comprises:

[0008] The qualification requirement acquisition module is used to obtain the set of qualifications of the accompanying persons required for the target access location and the minimum accompaniment duration based on the target access location identifier.

[0009] The candidate screening module is used to screen out candidate accompanying persons from the employee information database who meet the requirements of the accompanying persons' qualification set.

[0010] The availability determination module is used to determine, for each candidate companion, whether there is a continuous free period of a length not less than the minimum companion length within the expected access time period, based on the confirmed companion appointment record.

[0011] The escort allocation module is used to select an employee from the candidate escorts who have the continuous free time period as the assigned escort for the appointment request when there are candidate escorts, and to mark the corresponding time period in the employee's time occupation record;

[0012] The time window recommendation module is used to aggregate the free time of the candidate companions when there are no candidate companions with the continuous free time period, generate at least one recommended alternative time window with a duration not less than the shortest companion duration, and present it to the visitor for confirmation through the front-end interaction unit.

[0013] Furthermore, the escort allocation module selects from the candidate escorts according to a preset priority rule, which is determined at least based on the visitor's credit score, which is calculated based on the visitor's historical appointment behavior records.

[0014] Furthermore, the escort allocation module is also used to: calculate the fitness score of each candidate escort with the continuous free time period, and select the employee with the highest fitness score as the assigned escort; the fitness score is determined based on the candidate escort's qualification matching degree with respect to the required escort qualification set, the load rate during the expected access time period, and historical escort experience indicators.

[0015] Furthermore, it also includes an access reason risk adjustment module, which is used to identify the risks of the access reasons and dynamically adjust the relative magnitudes of the qualification weight, load weight and experience weight used to calculate the fitness score according to the identified risk level.

[0016] Furthermore, the fitness score is calculated according to the following formula:

[0017]

[0018] In the formula, , , These are the adjusted qualification weights, workload weights, and experience weights, respectively. For qualification matching, For load rate, It serves as a historical indicator of experience.

[0019] Furthermore, the time window recommendation module is specifically used to: summarize all the free time intervals of the candidate accompanying persons within the expected visit date, merge intervals that overlap or have adjacent intervals less than a preset buffer threshold, and select intervals with a length not less than the shortest accompanying length from the merged free intervals as the recommended candidate time windows.

[0020] Furthermore, the time window recommendation module is also used to: when an interval with a length not less than the shortest accompanying length cannot be obtained after merging processing, extract the maximum continuous free segment with a length not less than the shortest accompanying length for each candidate accompanying person, and select the maximum continuous free segment corresponding to the candidate accompanying person with the highest fitness score on the maximum continuous free segment to generate a unique recommendation time window.

[0021] Furthermore, the companion assignment module is also used to: when there are multiple candidate companions with the highest fitness scores, prioritize selecting the employee with the lower load rate as the assigned companion.

[0022] Furthermore, it also includes a credit scoring module for calculating a visitor's credit score based on the visitor's historical appointment records, which include at least the number of times a visitor defaults and cancels their appointments; the accompaniment allocation module determines the selection priority based on the visitor's credit score.

[0023] A company visitor appointment management method, applied to any of the systems described above, includes:

[0024] Receive a reservation request from a visitor and obtain the visitor's identifier, reason for visit, target location identifier, and expected visit time period.

[0025] Based on the target visit location identifier, obtain the set of qualifications of the accompanying personnel required for the visit location and the minimum accompanying duration;

[0026] Candidate escorts are selected from the employee information database who possess the qualifications to meet the aforementioned requirements.

[0027] For each candidate companion, based on the confirmed companion appointment record, determine whether the candidate companion has a continuous free period of not less than the minimum companion duration within the expected visit time period;

[0028] When there are candidate escorts with the aforementioned continuous free time periods, an employee is selected from the candidate escorts as the assigned escort, and the corresponding time period is marked in the employee's time occupation record.

[0029] If there are no candidate companions with the aforementioned continuous free time slots, the free time of the candidate companions is aggregated to generate at least one recommended alternative time window with a duration not less than the shortest companionship duration. The recommended alternative time window is then presented to the visitor for confirmation, and a final appointment record is generated based on the visitor's confirmation information.

[0030] The present invention has the following beneficial effects:

[0031] This invention integrates the qualifications of accompanying personnel, real-time workload, and visitor credit scores to automatically and collaboratively allocate appointment times and optimal accompanying personnel, reducing manual scheduling and communication review processes and improving the automation level of appointment processing. Credit scores and appointment priorities calculated based on visitor historical behavior help optimize the fairness and rationality of resource allocation. Integrating risk-adjusted weights for visit reasons allows for a greater focus on matching experienced accompanying personnel with high-risk situations, enhancing the targeted nature of security control. A time-window re-recommendation mechanism provides alternative solutions when no available personnel are available, reducing the appointment failure rate. The closed-loop utilization of data throughout the entire process supports subsequent statistical analysis and credit iteration, helping to improve the standardization and operational efficiency of visitor management in controlled areas.

[0032] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Please see Figure 1 As shown, this invention is a company visitor appointment management system, comprising a front-end interaction unit and a back-end management unit. The front-end interaction unit is used to receive appointment requests initiated by visitors, and the appointment request includes at least a visitor identifier, the reason for the visit, a target location identifier, and a desired visit time period. The back-end management unit includes:

[0038] The qualification requirement acquisition module is used to obtain the set of qualifications of the accompanying personnel required for the target visit location and the minimum accompaniment duration based on the target visit location identifier;

[0039] The candidate screening module is used to screen out candidate accompanying persons from the employee information database who meet the qualification requirements.

[0040] The availability determination module is used to determine, based on the confirmed accompaniment appointment records, whether there is a continuous free period of no less than the shortest accompaniment duration for each candidate accompaniment person within the expected visit time period.

[0041] The escort assignment module is used to select an employee as the assigned escort for the appointment request from among the candidate escorts who have continuous free time periods, and to mark the corresponding time period in the employee's time occupancy record when there are candidate escorts with continuous free time periods.

[0042] The time window recommendation module is used to aggregate the available time of candidate companions when there are no candidate companions with continuous free periods, generate at least one recommended alternative time window with a duration not less than the shortest companion duration, and present it to the visitor for confirmation through the front-end interactive unit.

[0043] The escort allocation module selects from the candidate escorts according to preset priority rules. The priority rules are determined at least based on the visitor's credit score, which is calculated based on the visitor's historical appointment behavior records.

[0044] The escort assignment module is also used to: calculate the fitness score of each candidate escort with a continuous free period, and select the employee with the highest fitness score as the assigned escort; the fitness score is determined based on the candidate escort's qualification matching degree with the required escort qualification set, the load rate during the expected access period, and historical escort experience indicators.

[0045] It also includes an access reason risk adjustment module, which is used to identify risks in access reasons and dynamically adjust the relative sizes of qualification weights, load weights and experience weights used to calculate fitness scores based on the identified risk level.

[0046] Fitness score is calculated using the following formula:

[0047]

[0048] In the formula, , , These are the adjusted qualification weights, workload weights, and experience weights, respectively. For qualification matching, For load rate, It serves as a historical indicator of experience.

[0049] The time window recommendation module is specifically used to: summarize all available time intervals of candidate accompanying persons within the expected visit date, merge intervals that overlap or have adjacent intervals less than a preset buffer threshold, and select intervals with a length not less than the shortest accompanying person length from the merged available intervals as recommended candidate time windows.

[0050] The time window recommendation module is also used to: when an interval with a length not less than the shortest companion length cannot be obtained after merging, extract the longest continuous free segment with a length not less than the shortest companion length for each candidate companion, and select the longest continuous free segment corresponding to the candidate companion with the highest fitness score on the longest continuous free segment to generate a unique recommendation time window.

[0051] The companion assignment module is also used to: when there are multiple candidates with the highest fitness scores, prioritize the employee with the lowest load rate as the assigned companion.

[0052] It also includes a credit scoring module, which calculates a visitor's credit score based on the visitor's historical appointment records, which include at least the number of times a visitor defaults and cancels their appointments; and an accompaniment allocation module, which determines the selection priority based on the visitor's credit score.

[0053] Please see Figure 2 As shown, a company visitor appointment management method, applied to any of the above-mentioned systems, includes:

[0054] Receive a reservation request from a visitor and obtain the visitor's identifier, reason for visit, target location identifier, and expected visit time period.

[0055] Based on the target visit location identifier, obtain the set of required accompanying personnel qualifications and the minimum accompanying duration for that visit location;

[0056] Candidate escorts are selected from the employee information database based on the set of qualifications of escorts who meet the requirements.

[0057] For each candidate escort, based on the confirmed escort appointment records, determine whether the candidate escort has a continuous free period of not less than the shortest escort duration within the expected visit time period;

[0058] When there are candidate escorts with consecutive free periods, select one employee from the candidate escorts as the assigned escort, and mark the corresponding time period in the employee's time occupation record;

[0059] If there are no candidate companions with consecutive free periods, the free time of the candidate companions is aggregated to generate at least one recommended alternative time window with a duration not less than the shortest companionship duration. The recommended alternative time window is presented to the visitor for confirmation, and the final appointment record is generated based on the visitor's confirmation information.

[0060] The specific application of this embodiment is as follows:

[0061] Step S1: Receive and parse visitor appointment requests

[0062] Visitors submit reservation requests through the front-end interactive interface based on fantasy-admin. The request includes the following complete information: visitor name, contact number, ID number, visitor type, reason for visit, target location identifier, desired date and time of visit. The backend Spring Boot 3 service receives JSON data, validates the required fields and format, and then extracts all fields and stores them in the request context. The access location identifier uses a unique regional code within the system for subsequent retrieval of security access requirements for that region.

[0063] Step S2: Calculate visitor credit score and appointment priority

[0064] The backend retrieves historical appointment records based on the visitor's ID number and calculates the total number of appointments made by that visitor. Number of times normally completed Number of breaches not reached and the number of times to actively cancel Calculate your credit score:

[0065]

[0066] In the formula, A positive deduction coefficient is configured by the backend system settings module, for example, set... Then, based on the visitor type, query the type weight table to obtain the type coefficient. (VIP visitor) Regular visitors Temporary visitors Normalize the credit score. Priority is calculated based on the number of days in advance of the appointment:

[0067]

[0068] In the formula, The number of days between the scheduled appointment time and the access date; For reference, the maximum number of days in advance (e.g., 30); As weight and This priority system takes into account both visitor reliability and the time of appointment, ensuring that high-quality visitors and those who make appointments in advance receive priority allocation.

[0069] Step S3: Analyze the required qualifications and minimum duration of escorts for the visited location.

[0070] The backend query area-qualification mapping table retrieves the set of mandatory safety qualifications for accompanying personnel required for that location based on the target access location identifier. Examples include "Controlled Area Access Permit," "Special Equipment Operation Authorization," and "Emergency Rescue Certification." It also reads the minimum accompaniment duration required for that location. Controlled areas typically require full-time accompaniment for at least one hour. If the location does not have specific qualification requirements, the default will apply. , .

[0071] Step S4: Construct a candidate companion set and obtain availability.

[0072] Query the company's employee information database to obtain information on each employee. A collection of certified qualifications Filter to meet The employees form a candidate set. .like If the message is empty, immediately return "No matching qualified accompanying person found" to the front desk, and the process will terminate. For each employee, obtain their work hours on the expected visit date. It also retrieves the approved accompaniment appointment records in the backend and extracts the employee's... The time segment already occupied within. Let the total occupied time be... And determine whether there exists a length not less than The maximum consecutive idle segment is determined. If no such segment exists, the employee is unavailable during that time period; otherwise, the start and end times of the maximum consecutive idle segment are recorded for subsequent allocation. Load factor is calculated.

[0073]

[0074] In the formula, This represents the end time of the visitor's expected visit period. The start time of the visitor's expected visit period;

[0075] When the load factor exceeds 1, it is truncated to 1.

[0076] Step S5: Adjust the fitness weights based on the risk of merging access reasons.

[0077] The backend performs keyword matching on the access reason field. If it contains words such as "equipment maintenance," "sample collection," "environmental monitoring," or "hazardous operation," the risk factor of the reason will be adjusted. Set to 0.8 for normal access and 0.2 for general access. According to... Dynamically adjust the experience weight increment in employee fitness scores to give greater weight to the experience of accompanying personnel in high-risk situations. Set a base weight. and The adjusted weights are as follows:

[0078]

[0079] In the formula, This is the maximum increase in experience weight, preset by the administrator. This adjustment ensures that the sum of the weights is always 1, and Neither of them are negative.

[0080] Step S6: Calculate the fitness score for each available candidate employee.

[0081] For employees marked as available in step S4 Calculate the qualification matching degree (since full coverage has been achieved, at this point...). (If the subsequent extended part matches the scenario, it can be less than 1). Calculate the empirical index:

[0082]

[0083] In the formula, This represents the cumulative number of times the employee has successfully completed escort duties throughout their history. Set a preset empirical saturation threshold (e.g., 50 iterations). Calculate the final fitness score:

[0084]

[0085] Step S7: Execute appointments by priority - personnel matching and time slot allocation

[0086] All pending appointment requests are sorted by priority. Sort by highest to lowest. For each appointment, in Select the current score The highest and possessing satisfaction Employees with consecutive periods of free time will be designated as accompanying persons. In case of a tie for the highest score, the employee load rate will be prioritized. For lower-priority employees, after confirmation of allocation, immediately mark the corresponding time slot as occupied in the employee's time occupancy model and recalculate its remaining availability to prevent subsequent low-priority appointments from using conflicting time slots. The allocated companion ID and confirmed time slot are written into the appointment data. If the allocation is successful, the record status is recorded as "Pending Review (Companion Assigned)".

[0087] Step S8: Time window re-recommendation when no employees are available

[0088] If a certain appointment cannot be fulfilled in step S7 because all candidate employees are unable to provide a satisfactory service... If allocation fails due to consecutive idle periods, the system will re-recommend the time window upon startup. (Summary) For all employees within the expected access date, a time-slice merging algorithm is executed: all free intervals are sorted by their starting point, and intervals that overlap or are adjacent with an interval less than the buffer time (e.g., 5 minutes) are merged to obtain a common list of merged free intervals. The length of each interval is then filtered from this list. The time intervals are sorted chronologically to form a recommended alternative time window list. If no suitable public free space exists, then a length is searched individually for each employee. The maximum consecutive free period is used to calculate the employee's score during that time period. The combination of the highest scores is used to generate a unique recommended time window. The recommended time window and the corresponding accompanying employee's name (displayed in anonymized form) are returned to the visitor's front end with the message "No suitable accompanying person is available for the current time period. We suggest adjusting to the following time."

[0089] Step S9: Visitor confirmation and generation of final appointment record.

[0090] Visitors can choose the adjusted time slot based on the recommendations, or keep the original time slot and have the system continuously retry. After confirmation, the reservation data is submitted again. The backend will write the final confirmed reservation time slot, visitor name, contact number, ID number, visitor type, reason for visit, location, and assigned accompanying person ID into the reservation record table, generating a unique reservation number, and setting the status to "pending review". At the same time, the occupancy information of this allocation will be persistently updated in the accompanying person's scheduling load table.

[0091] Step S10: Notification Push and Data Synchronization

[0092] Based on the contact number and name in the appointment record, the backend sends a notification to the frontend via SMS or webpage message stating "Appointment submitted, accompanying person is XX, please wait for approval," and synchronizes the accompanying person's information to their work to-do list. All historical data is written to the operation log for subsequent statistical analysis, blacklist updates, and credit scoring iterations, forming a closed-loop process. Thus, all collected data (visitor name, contact number, ID number, visitor type, reason for visit, location, appointment time slot, and accompanying person information) is effectively used for calculation, matching, recording, and feedback, with no data waste.
