A resource accommodation assistance system includes a plurality of information processing apparatuses each including: a storage unit configured to hold a distributed ledger storing transactions issued in accordance with events including power sale from an ordinary household to a retail electric utility, power purchase by a customer through the power sale, and commodity purchase by the ordinary household of a commodity from the customer with a payment token gained from the retail electric utility through the power sale; and an arithmetic unit configured, in the event of commodity purchase, to execute a smart contract, to carry out a transaction for payment on the commodity purchase using the payment token with a predetermined premium bearing by the customer, and to store, in the distributed ledger, the transaction subjected to a predetermined process executed together with another information processing apparatus among the information processing apparatuses.

Resource accommodation assistance system, resource accommodation assistance method, and resource accommodation assistance apparatus

An energy operation system, apparatus, and method capable of stably supplying energy and providing adjustment control based on prediction precision and planning precision for energy supply and demand. An energy operation apparatus includes a demand predictor, planner, evaluator, and solution quality controller. The demand predictor predicts demand and/or a power generation amount of future energy in a management area. The planner prepares a future energy supply plan in the management area based on a prediction. The evaluator evaluates supply and/or demand conditions including at least one of future weather in the management area, energy demand in the management area, a demand density and/or a generation density of future energy in the management area. The solution quality controller controls the quality of at least one of a prediction solution of the demand predictor and the energy supply plan of the planner based on an evaluation result from the evaluator.

Energy operation apparatus, method, and system

Proposed is a data analyzing system and method capable of performing highly reliable analytical processing which matches the actual situation. In a data analyzing device and method in which load data is classified into a plurality of clusters in consumer units based on the load data representing the power usage of each consumer for each unit time and the attribute information of each consumer, a diagnostic decision tree is generated for classifying the consumer into one of the clusters based on the attribute information of that consumer.

Data analyzing system and method

To minimize the amount of calculation for changing an operation schedule even when there is an increase in the number of sites. A management computer calculates a first total schedule value, which is the total of the schedule values for each of the sites within a first time frame. If the first total schedule value exceeds a first target value set in advance, the management computer: calculates a first excess amount of the first total schedule value in relation to the first target value; selects, as a first site, a site subjected to a change in a demand schedule from a group of candidate sites satisfying a candidate criterion set in advance from among a plurality of the sites, the selection being performed on the basis of information on the facility characteristics for each of the sites; changes a first demand schedule of the first site in the first time frame; and transmits the changed first demand schedule to a control device of the first site.

Energy management system, method, and device for multi-site energy management

To propose an information processing device and method capable of planning an effective scheme, such as distributing information appropriate to a user. Time-series positional data composed of time-series positional information of a mobile communication body are collected, and a regular behavior of a user of the mobile communication body is estimated on the basis of the collected time-series positional data of the mobile communication body.

Information processing device and method

Proposed are an information distribution apparatus and method capable of efficiently distributing information. Clustering processing of collecting time series position data, which is configured from position information of a plurality of mobile communication objects, and classifying the time series position data into a plurality of clusters based on the collected time series position data of each of the mobile communication objects is executed, profiling processing of determining, for each of the clusters, a dominant attribute of each user in which the time series position data was allocated to the relevant cluster based on pre-registered attribute information of each of the users of each of the mobile communication objects is executed, and, for each of the clusters, information to be distributed to each of the users in which the time series position data was allocated to the relevant cluster is determined based on a processing result of the profiling processing.
