Abstract: When an event such as maintenance occurs, a model in which a tendency of input data changes due to an influence of the maintenance and retraining is required is specified. Model identifiers that specify the machine learning models and are unique to the machine learning models and sensor identifiers that specify the sensors that output the sensor data serving as the input data of the machine learning models and are unique to the sensors are managed to be in association with each other. A degree of influence indicating a change in tendency of the sensor data before and after the maintenance operation is performed is obtained for each maintenance event identifier that specifies a maintenance operation performed on a device and is unique to the maintenance operation, and the degree of influence is managed in association with each of the sensor identifiers. When the sensor whose degree of influence satisfies a predetermined condition is influenced by the maintenance operation, the model identifier associated with the sensor identifier of the sensor satisfying the condition is presented.

Abstract: The data center (DC) linking system provides a line under specified communication conditions to each tenant, wherein in each DC, a virtual network identifier (i) and/or (ii) serving as a communication type identifier which separates communications of each tenant of each of a plurality of DCs and a virtual network identifier (iii) which is provided by a carrier and serves as a line identifier which separates a plurality of communications having different communication conditions are identified and managed in association with each other; and the communications of each tenant are identified on the basis of the communication type identifier. Any one line identifier for allocating a line having a communication condition desired by a tenant is assigned to each communication identified on the basis of communication content in a transmitting side DC.
