[0004] [Patent Document 1] Patent Publication No. 2021-047524 Summary of the Invention [Problem to be solved by the invention]

[0005] The following analysis is given by the inventors.

[0006] In a company, if employees have fixed seats, the conference rooms they use are also necessarily fixed. However, in response to the coronavirus pandemic, the shift to a free address system in offices has been rapidly promoted.

[0007] When holding a meeting in a company that uses a free address system, it is not possible to know which seat each participant will be using on the day, so a conference room that is extremely far away from some of the participants may be reserved. Also, even if many participants will be participating in the meeting via telework on the day of the meeting, a conference room that is too large for the number of participants who will actually be participating in the meeting may be reserved. Therefore, it has become important for employees who use free address seats to choose a conference room to hold a meeting.

[0008] An object of the present invention is to provide a conference management server, a free address management system, a conference management method, and a program that contribute to shortening the travel time of conference participants to a conference room. [Means for solving the problem]

[Brief description of the drawings]

[0015] [Figure 1] 1 is a block diagram showing an example of a configuration of a free address management system according to the present disclosure. [Diagram 2] 5 is a flowchart illustrating an operation of a conference management server according to the present disclosure. [Diagram 3] FIG. 2 is a diagram illustrating a configuration of a computer that constitutes a conference management server according to the present disclosure. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] In this disclosure, the drawings may be associated with one or more embodiments. In addition, each embodiment described below may be combined with other embodiments as appropriate, and the present invention is not limited to each embodiment.

[0017] First, an outline of one embodiment will be described with reference to the drawings. Note that the reference numerals in the drawings are given to each element for convenience as an example to aid in understanding, and are not intended to limit the present invention to the illustrated form. Also, the connection lines between blocks in the drawings and the like referred to in the following description include both bidirectional and unidirectional lines. The unidirectional arrows are used to diagrammatically indicate the flow of the main signal (data), and do not exclude bidirectionality.

[0018] Fig. 1 is a block diagram showing an example of the configuration of a free address management system according to the present disclosure. Referring to Fig. 1, the free address management system 10 includes a conference management server 100 and a seat management server 200, which are connected to each other via a network 300.

[0019] The conference management server 100 determines a conference room on the day of the conference (for example, at the start of work on the day of the conference) and notifies the conference participants of the conference room. The conference management server 100 may have a function for notifying by email or the like. The conference management server 100 also holds the travel time of each conference participant from their respective seat positions to their respective conference rooms. The travel time may be calculated as an approximate travel time from information such as a floor map. Furthermore, if it is necessary to use an elevator, the travel time may include the elevator waiting time. The seat management server 200 manages the seats of the free address system. The seat management server 200 also manages the working status of users (working in the office / teleworking / vacation, etc.) and the seat position of each user. Note that the seats may be reserved in advance by the users, or may be determined by the seat management server 200 on the day.

[0020] Next, the conference management server 100 and the seat management server 200 of the free address management system 10 will be described in detail.

[0021] On the day of the conference, the conference management server 100 acquires from the seat management server 200 whether the work status of the conference participants is "attendance" and the seat positions of the conference participants whose work status is "attendance."

[0022] Next, the conference management server 100 extracts conference room candidates based on the conference room usage time, the number of conference room participants whose work status is "attendance at the office," and other desired conference room conditions.

[0023] Next, the conference management server 100 calculates the travel time from the seat position of each of the conference participants whose work status is "attend" to each of the candidate conference rooms, and determines the conference room in which to hold the conference from among the candidate conference rooms based on the calculated travel time.

[0024] Next, the conference management server 100 notifies the conference participants of the conference room in which the conference will be held.

[0025] Thus, according to one embodiment of the present invention, conference rooms are extracted based on the number of conference participants whose working status is "attending the office" (hereinafter also referred to as "attending the office"). This makes it possible to hold a conference without the need for the conference participants to decide in advance whether to attend the conference in a conference room or by telework.

[0026] Furthermore, according to one embodiment of the present invention, by using a conference room that is appropriate for the number of conference participants who are in the office and that is close to the conference room's seats, it is possible to reduce the travel time of conference participants to the conference room, enabling them to use their time more effectively to carry out their work.

[0027] Therefore, as described above, according to one embodiment of the present invention, it is possible to provide a conference management server, a free address management system, a conference management method, and a program that contribute to shortening the travel time of conference participants to a conference room.

[0028] [First embodiment] Next, the first embodiment will be described in detail with reference to the drawings. Fig. 1 is a block diagram showing an example of the configuration of a free address management system according to the present disclosure. Fig. 1 is the same drawing as that described in the overview of one embodiment of the present invention, so the description will be omitted.

[0029] In the first embodiment, it is assumed that there are multiple free address areas (areas with free address seats) (for example, the 3rd and 7th floors of a building), conference rooms other than the free address areas can be used as conference rooms for holding meetings, and the seat management server 200 determines the seats for employees based on predetermined conditions when they arrive at work (in this case, employees cannot select a seat close to the conference room they will be using that day). However, the present invention is not limited to application to such cases.

[0030] The conference management server 100 performs processing to determine the conference room to be used for the conference, for example, at the start of work on the day of the conference. Note that this processing may be performed at any timing, such as one hour before the start of the conference, instead of at the start of work. Also, the conference management server 100 is assumed to have been notified in advance by the conference organizer of information such as the conference room usage time, conference participants, and desired conference room conditions, and to retain such information.

[0031] Next, a description will be given of the operation of the first embodiment. Fig. 2 is a flowchart showing the operation of the conference management server 100 according to the present disclosure. The operation starts in step S201.

[0032] Next, in step S202, the conference management server 100 acquires the working status of the conference participant (attending work / teleworking / vacation, etc.) and, if attending work, the seat position of the conference participant from the seat management server 200. This allows the conference management server 100 to acquire the working status of the conference participant as to whether or not attending work is the case.

[0033] Next, in step S203, the conference management server 100 extracts available conference rooms using search conditions such as the conference room usage time, the number of conference room participants who are in the office, and desired conference room conditions.

[0034] If a conference room candidate is found (step S204 YES), the travel time of the conference participants is calculated from each of the conference room candidates and the seat positions of the conference participants (step S205). Based on the calculated travel time, a conference room that will minimize the travel time is selected from among the conference room candidates (step S206), and the process proceeds to step S211. Note that a conference room may be selected from among the conference room candidates so that the longest travel time among the participants is minimized. Alternatively, a conference room may be selected from among the conference room candidates so that the total travel time of the participants for the conference room candidates is minimized.

[0035] If there is no available conference room (step S204 NO), or if there are search conditions that can be loosened based on the desired conference room conditions (step S207 YES), for example, if there is a room that is suitable for online conferences with dedicated cameras, microphones, monitors, etc., and if there are search conditions that allow the priority to be changed arbitrarily, such as using that room preferentially or not using open space conference rooms (step S207 YES), then in step S208, the search conditions are loosened and re-extraction is performed. If a conference room candidate is found after re-extraction (step S209 YES), the process proceeds to step S205, and the above-mentioned steps S206 and S211 are performed.

[0036] If there is no search condition that can be relaxed in step S207 (NO in step S207), or if no meeting room candidate is found even after re-extraction in step S208 (NO in step S209), the online meeting is determined in step S210, and the process proceeds to step S211.

[0037] After the conference room is determined in step S206, or after the online conference is determined in step S210, the conference management server 100 notifies the conference participants of the determined conference room or the decision to hold an online conference in step S211. For example, when the conference room is determined in step S206, if there are conference participants who are teleworking, an online conference may also be set up and notified to the conference participants. In addition, the travel time to the conference room may also be notified to the conference participants. Next, the process proceeds to step S212, where the process ends.

[0038] According to the first embodiment of the present invention, the conference room to be used for a conference is determined based on the number of conference participants who are in the office and the travel time of the conference participants, thereby reducing the travel time of the conference participants to the conference room and enabling them to use their time more effectively for work.

[0039] Furthermore, according to the first embodiment of the present invention, by determining the conference room based on the number of conference participants who are in the office, the conference organizer can hold the conference room without having to worry about whether the conference participants will join in advance in a conference room or by teleworking.

[0040] Therefore, according to the first embodiment of the present invention, it is possible to provide a conference management server, a free address management system, a conference management method, and a program that contribute to shortening the travel time of conference participants to a conference room.

[0041] [Second embodiment] Next, a second embodiment will be described. The second embodiment is an embodiment for a case where multiple conferences are held at the same time on the same day, and a conference room for each conference is determined so as to minimize the travel time of the conference participants of the multiple conferences held at the same time.

[0042] When multiple conferences are held at the same time on the day of the conference, the conference management server 100 acquires from the seat management server 200 whether the work status of the conference participants of each conference is "attend" or not, and the seat positions of the conference participants whose work status is "attend". Next, the conference management server 100 extracts conference room candidates for each conference based on the conference room usage time of each conference, the number of conference participants whose work status is "attend", and other desired conference room conditions. Next, the conference management server 100 calculates the travel time from each seat position of the conference participants whose work status is "attend" to the conference room candidate of each conference. Next, the conference management server 100 calculates a second travel time for each conference room candidate from the travel time for each conference of the multiple conferences.

[0043] Next, the conference management server 100 determines a conference room in which each conference will be held from among the conference room candidates for each conference so that the total of the second travel times of the conference room candidates determined for each conference is minimized.

[0044] Finally, the conference management server 100 notifies the conference participants of each conference of the conference room in which each conference will be held.

[0045] Next, a specific example of the operation of the second embodiment of the present invention will be described.

[0046] For example, first, a search is performed for meetings that are to be held at the same time. It is assumed that the search has revealed that meetings A, B, and C are to be held at the same time.

[0047] The conference management server 100 calculates the travel time from the seat position of each conference participant whose work status is "attend" to the conference room candidate for each conference for each of the multiple conferences A, B, and C. Furthermore, the conference management server 100 calculates a second travel time for each of the multiple conferences A, B, and C for each of the multiple conferences from the calculated travel time to each of the conference room candidate.

[0048] The second travel time for each candidate conference room may be a sum of the travel times of the conference participants for each candidate conference room.

[0049] As an example, for conference A, there are seven conference participants, five of whom are at free address seats on the third floor, and two are at free address seats on the seventh floor. If the conference room candidates for conference A are conference room 302, conference room 402, and conference room 503, the second travel time for conference room 302 is calculated to be 55 minutes, the second travel time for conference room 402 is calculated to be 80 minutes, and the second travel time for conference room 503 is calculated to be 105 minutes.

[0050] As for conference B, it is assumed that there are six conference participants, four of whom are at free address seats on the third floor, and two are at free address seats on the seventh floor. If the conference room candidates for conference B are conference room 302, conference room 305, and conference room 306, it is assumed that the second travel time for conference room 302 is calculated to be 50 minutes, the second travel time for conference room 305 is calculated to be 52 minutes, and the second travel time for conference room 306 is calculated to be 54 minutes.

[0051] For conference C, there are four conference participants, two of whom are at the free address seats on the third floor, and two are at the free address seats on the seventh floor. If the conference room candidates for conference C are conference rooms 505, 506, and 507, the second travel time for conference room 505 is calculated to be 60 minutes, the second travel time for conference room 506 is calculated to be 62 minutes, and the second travel time for conference room 507 is calculated to be 64 minutes.

[0052] If there is a conference participant who moves significantly slower than the others, such as a person using a wheelchair, the travel time may be adjusted when calculating the travel time.

[0053] As described above, when conference room candidates are extracted for each of conferences A, B, and C and the second travel time for each is calculated, a conference room for each conference is determined from the conference room candidates for each conference so that the total of the second travel times of the conference room candidates is minimized when determining conference rooms for each of conferences A, B, and C. Conference room 302 is extracted as a conference room candidate for both conferences A and B, but conference rooms cannot be used in duplicate, so conference room 302 is determined for conference A, conference room 305 for conference B, and conference room 505 for conference C. The total of the second travel times for the determined conference rooms for conferences A, B, and C is the minimum value of 167 minutes.

[0054] According to the second embodiment of the present invention, it is possible to provide a conference management server, a free address management system, a conference management method, and a program that contribute to shortening the travel time of conference participants to conference rooms for multiple conferences held at the same time, thereby enabling work to be done with more effective use of time.

[0055] In the first and second embodiments of the present invention described above, the conference room is determined according to the seat, but the conference room may be reserved in advance, and the seat management server 200 may reserve a seat near the conference room when the employee arrives at work on the day.

[0056] Although each embodiment of the present invention has been described above, the present invention is not limited to the above-mentioned embodiments, and further modifications, substitutions, and adjustments can be made without departing from the basic technical idea of ​​the present invention. For example, the network configurations, element configurations, and message expression forms shown in the drawings are examples to help understand the present invention, and the present invention is not limited to the configurations shown in these drawings. In addition, "A and / or B" is used to mean at least either A or B.

[0057] The procedures shown in the first and second embodiments can be realized by a program that causes a computer (9000 in FIG. 3) functioning as the conference management server according to the present invention to function as the conference management server. Such a computer is exemplified by a configuration including a CPU (Central Processing Unit) 9010, a communication interface 9020, a memory 9030, and an auxiliary storage device 9040 in FIG. 3. That is, the control program of the conference management server is executed by the CPU 9010 in FIG. 3, and an update process of each calculation parameter held in the auxiliary storage device 9040 or the like is performed.

[0058] The memory 9030 is a RAM (Random Access Memory), a ROM (Read Only Memory), or the like.

[0059] In other words, each part (processing means, function) of the conference management server shown in the first and second embodiments described above can be realized by a computer program that causes the processor of the computer to execute each of the above-mentioned processes using its hardware.
