[Second Embodiment]
Next, the ICT service environmental impact assessment system 10 according to the second exemplary embodiment of the present invention will be described.
In the first embodiment, the case where the evaluation target service and the comparison target service correspond one-to-one has been described as an example. However, the ICT service has many functions, and these functions may not correspond to one comparison target service, and may correspond to a plurality of comparison target services. In the present embodiment, a case where such an evaluation target service and a comparison target service correspond one-to-many will be described.

  In the present embodiment, the service search unit 16A compares, as comparison target specifying functions, a plurality of candidate services selected and operated as comparison target services from among the candidate services displayed on the screen by the data output unit 12. It has a function to specify as a service.

And the overall environment related to the total environmental load of the service to be evaluated and the service to be compared The difference between the load volume, and a function for calculating environmental value of the evaluation target service.

Here, when the selected comparison target service is Sj (i is an integer of 1 to M), the environmental load related to the comparison target service Sj is Gj, and the contribution rate regarding the comparison target service Sj is Wj, these comparisons are made. The total environmental load Gs related to the target service Sj is obtained by the following equation (2).

  Therefore, for example, focusing on the short communication function and the photo sending function as the functions of the mobile mail service specified as the evaluation target service, the telephone service is specified as the comparison target service having the short communication function, and the comparison having the photo sending function. The mail service is specified as the target service.

[Effect of the second embodiment]
As described above, in the present embodiment, when a plurality of comparison target services are selected, the environmental load calculation unit 16D inputs the environmental load amount calculated for the comparison target service for each of the comparison target services. By calculating the product-sum of the contribution rate of the comparison target service with respect to the evaluation target service, the total environmental load amount of the comparison target service is calculated, and the environmental load amount of the evaluation target service and the comparison target service are calculated. The difference from the total environmental load is calculated as the environmental value of the service to be evaluated.

  As a result, even when the functions of the evaluation target service do not correspond to one comparison target service, but support across a plurality of comparison target services, the environmental value of the evaluation target service for these comparison target services is calculated. Can do.

  In the present embodiment, the contribution rate of each function of each service has been described as an example obtained by an operation input from the user. However, it is registered in the service attribute information DB 15A and the total environmental load is calculated. In doing so, the environmental load calculation unit 16D may acquire a contribution rate related to a function corresponding to each comparison target service among the evaluation target services.

In addition, the service attribute information DB 15A may store the degree of use such as the number of users and the utilization rate of each service, and these can be used as selection conditions for the comparison service. FIG. 9 shows another configuration example (degree of use) of the service attribute information DB. Here, usage degree information such as a data year, the number of users used, and a usage rate is additionally registered for each service.
Thus, when searching for candidate services, by limiting the usage degree information by an operation input from the data input unit 11, for example, when a year for comparative evaluation is determined, it is minor to use. By removing services and searching for major services as candidate services, it is possible to narrow down the services that are candidates for comparison, and it is possible to search for candidate services that meet the purpose of the environmental impact assessment, and the appropriate comparison target services are efficient. You can choose well.

  Moreover, you may calculate using the number of utilization users or a utilization rate instead of the contribution rate of Formula (2) mentioned above. For example, when comparing e-mails as means for communicating, as a conventional means, it is assumed that the utilization rate of the telephone service is 40% and the utilization rate of the mail service is 60% as a communication means for a certain year. In that case, the load of the conventional means may be calculated and output by adding the 40% calculated value of the mail environmental load evaluation result and the 60% calculated value of the telephone service environmental load evaluation result.
