The attending employee identification unit 11 of the video conference cost-effectiveness calculation system 10 identifies the attending employees on the participating side by using the methods 1 to 4 shown below.

(Method 1)
When an employee attending the participation side connects his / her own employee notebook PC (hereinafter referred to as an employee notebook PC 4c) to a video conference dedicated terminal 3c or brings an employee notebook PC 4c to a television for sharing materials, etc. When attending a meeting, the attending employees are made to take a picture of their employee ID with the camera of the video conference dedicated terminal 3c or the employee notebook PC 4c, and the video conference system 20 is taken from the video conference dedicated terminal 3c or the employee notebook PC 4c. Based on the employee ID image data of the attending employee on the participating side (information for identifying the attending employee on the participating side), the employee code is collated with the employee code of the employee information stored in the employee DB 15.

(Method 2) When the attending employee identification unit 11 on the participating side has a face recognition function, the attending employee on the participating side is made to take a picture of his / her own face with the camera of the video conference dedicated terminal 3c or the employee notebook PC 4c, and the TV. Employee information stored in the employee DB 15 based on the face image data of the attending employees on the participating side (information for identifying the attending employees on the participating side) transmitted from the conference terminal 3c or the employee notebook PC 4c via the video conference system 20. Collate with the face photo data of.

(Method 3) Participating employees are made to enter their own employee code into the video conference dedicated terminal 3c or employee notebook PC 4c, and are transmitted from the video conference dedicated terminal 3c or employee notebook PC 4c via the video conference system 20. It is collated with the employee code of the employee information stored in the employee DB 15 based on the coming employee code data (information for identifying the attending employee on the participating side).

(Method 4) Based on the IP address of the employee notebook PC 4c (information for identifying the attending employee on the participating side), the IP address of the PC management information stored in the in-house PC management DB 14 is collated.

When the participating side attending employee identification unit 11 identifies the participating side attending employee, it acquires the employee code of the identified participating side attending employee from the employee DB 15, and outputs the acquired employee code to the cost effectiveness calculation unit 12.

After that, when the video conference is completed, the registrant and the attending employees on the participating side log out from the video conference system 20 using the video conference dedicated terminals 3a and 3c, respectively, and exit the video conference.
Further, the reservation server 21 of the video conference system 20 outputs to the cost-effectiveness calculation unit 12 that the video conference has ended, and deletes the reservation information of the video conference from the reservation DB 24.

When the reservation server 21 inputs that the video conference has ended, the cost-effectiveness calculation unit 12 receives the video conference information received from the reservation server 21 and the attending employee identification unit 11 of the participating side. Based on the employee code, the video conferencing cost effectiveness is quantitatively calculated according to steps 1 to 5 shown below.

(Procedure 1) The location of the video conferencing terminals 3a and 3c by searching the video conferencing terminal DB13 based on the identification code of the specific video conferencing terminals 3a and 3c of the host business office and the participating business office (hereinafter, By specifying "the place where the host and the participating video conferencing terminals are installed"), the host business and the participating business are specified.

(Procedure 2) Calculation of round-trip transportation costs Search DB16 for transportation means, etc. based on the specified host office and participating business office (that is, the specified host and participating video conferencing terminal installation locations) and host the event. The charge data of the means of transportation between the side and the participating business establishments (that is, between the host side and the place where the video conferencing terminal is installed on the participating side) is acquired, and the acquired charge data is doubled to calculate the round-trip transportation cost.
At this time, if there is no transportation charge data between the host side and the participating business establishments in the transportation means DB16, the charge data of the transportation means is acquired using an existing transportation cost calculation application or the like, and round-trip transportation is performed. Calculate the cost.
Further, since the object of the present invention is a simple calculation of the cost-effectiveness of video conferencing, when there are a plurality of means of transportation on the route (for example, a bus, a tram, a subway, a taxi, etc.), the cheapest amount of money is used. The round-trip transportation cost is calculated using the transportation charge data. As a result, even in a video conference between the same organizer and participating offices, even if the participating employees use different transportation methods or the participating employees use different transportation methods for the outbound and inbound routes. It is possible to avoid overestimation and variation in the cost-effectiveness of video conferencing due to round-trip transportation costs, and it is possible to calculate the cost-effectiveness of video conferencing without waiting for the actual round-trip transportation costs to be charged by the attending employees.
For taxis, the round-trip transportation costs may be calculated using the taxi fare actually paid by the attending employees on the participating side, but between each office with reference to the taxi fare for the route that the employee has invoiced in the past. The taxi fare for calculating the transportation cost may be predetermined and stored in the transportation means DB16, and the round-trip transportation cost may be calculated using the taxi fare for calculating the transportation cost of the route. As a result, the cost effectiveness of the video conference can be calculated without waiting for the taxi fare to be charged by the attending employees.

(Procedure 3) Calculation of round-trip travel time Search DB16 for transportation, etc. based on the specified host and participating business establishments (that is, the specified host and participating video conferencing terminal installation locations), and search for the host and participating business sites. After acquiring the travel time data between the participating business establishments (that is, between the specified host side and the location where the video conference dedicated terminal is installed on the participating side), the acquired travel time data is doubled to calculate the round-trip travel time.
At this time as well, the round-trip travel time actually spent by the attending employees on the participating side may be used, but the average travel time between each business establishment is predetermined as the travel time between each business establishment and stored in the transportation means DB16. However, the round-trip travel time may be calculated by doubling the average travel time between the host and participating business establishments. As a result, the cost effectiveness of the video conference can be calculated without waiting for the report of the round-trip travel time actually spent by the attending employees on the participating side.
In addition, when there are multiple means of transportation between each business establishment, the average travel time when using the cheapest amount of transportation means is predetermined as the travel time between each business establishment and stored in the transportation means DB16. You may leave it. As a result, even in a video conference between the same organizer and the participating business establishments, it is possible to avoid overestimation and variation in the cost effectiveness of the video conference due to the round-trip travel time of the participating employees.
In addition, the walking time from the nearest bus stop to the participating business office (average walking time) should be included in the travel time, and the video conference cost effect will vary depending on the walking time from the nearest bus stop to the participating business office. May be able to be avoided.

(Procedure 4) Calculation of personnel expenses during movement Search the employee DB15 based on the employee code of the participating employee, obtain the personnel cost unit price of the participating employee, and use it as the acquired personnel cost unit price of the participating employee. Multiply the round-trip travel time calculated in step 3 above to calculate the labor cost during travel of the participating employees.

(Procedure 5) Calculation of video conferencing cost effect The video conferencing cost effect is calculated by summing the round-trip transportation cost calculated in step 2 and the on-the-go labor cost calculated in step 4.
If multiple employees attending the video conference participate in the video conference, the round-trip transportation costs and labor costs for each participating employee are calculated, and the calculated round-trip transportation costs and traveling labor costs for each participating employee are calculated. Calculate the total labor cost as a video conferencing cost effectiveness.

For example, the location of the organizer's office is XX city in XX prefecture, the location of the participant's office is XX city, and the cheapest means of transportation between the organizer and the participant's office. The fee is 1,000 yen, the travel time between the organizer and the participating offices when using this means of transportation is 1 hour, and the attending employees on the participating side are A (personnel cost unit price = 5,000 yen), If there are four people, B (personnel cost unit price = ¥ 3,000), C (personnel cost unit price = ¥ 2,000), and D (personnel cost unit price = ¥ 1,000), the video conference cost effect is as follows. It is calculated as follows.
Round-trip transportation fee: ¥ 1,000 x 2 x 4 people = ¥ 8,000 (see step 2 above)
Round-trip travel time: 1h x 2 = 2h (see step 3 above)
Labor costs on the move: (¥ 5,000 + ¥ 3,000 + ¥ 2,000 + ¥ 1,000) x 2h = ¥ 22,000 (see step 4 above)
Video conferencing cost effectiveness = ¥ 8,000 + ¥ 22,000 = ¥ 30,000 (see step 5 above)

In addition, as in the cases (1) to (3) shown below, the attending employees on the participating side may participate in the video conference using the employee mobile terminal 5.
(1) When using the employee mobile terminal 5 instead of the employee notebook PC 4 (2) When notifying the situation of the site in the event of a disaster (3) When participating during a business trip or while traveling In the case of (2) above It is not necessary to calculate the video conference cost effectiveness for the participating employees, but in the cases of (1) and (3) above, it is better to calculate the video conference cost effectiveness for the participating employees as well. ..

Therefore, the mobile terminal management information (data such as IP address, employee code of the employee being used, affiliation, title and name) of the employee mobile terminal 5 is also stored in the in-house PC management DB 14 to identify the attending employees on the participating side. Department 11 described above based on the information for identifying the attending employees on the participating side from the mobile terminal 5 for employees (employee ID image data, face image data, employee code data, and IP address of the mobile terminal 5 for employees). The attending employees on the participating side may be specified in the same manner as in the above methods 1 to 4, and the cost-effectiveness calculation unit 12 may calculate the video conference cost-effectiveness according to the above-mentioned procedures 1 to 5.

However, in the case of (3) above, since the attending employee on the participating side is not always near the participating business office (the place where the terminal dedicated to the video conference on the participating side is installed) when participating in the video conference, the cost-effectiveness calculation unit 12 By using the GPS function of the employee mobile terminal 5 or by reporting by the person himself / herself, the location at the time of participating in the video conference is specified to determine the transportation cost and travel time, and the round-trip transportation cost and traveling labor cost of the participating employees are calculated. It may be calculated.

In the above, the video conferencing in the company has been described as an example, but the present invention can also be applied to the video conferencing in the local government and the public enterprise.
