Abstract: A community evaluation system includes: effect model construction units and that construct, based on activity information data, history data, and communication history data, an effect model indicating a process in which a specific activity of a first community is reflected in communication in a network community and the communication in the network community is reflected in an activity of a second community; and an effect model evaluation unit that calculates an evaluation value of the process in the effect model, based on a size and a delay of a connection between the specific activity of the first community and the communication in the network community, and a size and a delay of a connection between the communication in the network community and the activity of the second community.

Abstract: Disclosed is a recommendation system 1 that includes a recommendation server 10. The recommendation server 10 includes a communication device and an arithmetic device. The communication device communicates with terminals 11 and 12 through a network 5. The arithmetic device distributes meeting candidate information including meeting conditions for holding a meeting to the terminals 12 of meeting participants, receives, from the terminals 12, information on disutility that is inflicted on the meeting participants by the meeting conditions, searches the places indicated by the meeting candidate information according to a disutility value for the meeting conditions and a disutility variation value per unit change in the meeting conditions in order to retrieve a meeting place that relatively reduces the disutility inflicted on all the meeting participants, and outputs the retrieved meeting place to the terminals 11 and 12. The disutility value and the disutility variation value are indicated by the information on disutility.

Abstract: A transportation service improvement for a user by reflects the degree of dissatisfaction of the user on the operation of a vehicle. In a transport service system that provides a service of operating a transport resource to transport a user, a third management device acquires a numerical value representing dissatisfaction of the user, a first management device gives a point corresponding to the dissatisfaction and stores a point for each of users in a first database, the point being usable for executing a request for the operation of the transport resource, and the third management device receives a request from the user and changes a plan of the operation of the transport resource based on the request and the status of the operation of the transport resource that is managed by a second database in exchange for the point given to the user that is managed by the first database.

Abstract: An object is to improve the accuracy of prediction of deterioration of railroad ground equipment. Provided is a maintenance assistance system for railroad ground equipment, comprising: an environmental-information storage part storing environmental information containing information on weather observed at a plurality of geographical points and on geographical conditions at the geographical points; and an environmental-load estimation part holding a relational formula indicating the relationship between aged deterioration of railroad ground equipment and the environmental information, and configured to, upon specification of railroad ground equipment for which to execute deterioration prediction, acquire the environmental information which is recorded at a point near the installed position of the railroad ground equipment, during the target period of the deterioration prediction, and predict the degree of aged deterioration of the railroad ground equipment by using the acquired environmental information and the relational formula.

Abstract: A power transaction plan planning support system for planning an electrical power transaction plan includes: a suppressible power consumption amount calculation unit which calculates a suppressible power consumption amount; a market information acquisition unit which acquires a market price and a position amount; a transaction plan planning rule which defines a position amount threshold value which serves as a criterion to determine whether the position amount is insufficient or not, as a determination condition to determine whether to buy electrical power from an electrical power transaction market or not; and a transaction plan planning unit which reduces the position amount threshold value by the suppressible power consumption amount and calculates an amount of the electrical power to be purchased from the electrical power transaction market on the basis of the reduced position amount threshold value, the market price, and the transaction plan planning rule.
