Abstract: A rule generation device according to an embodiment includes: a database in which, for each fault, fault factor information including a fault factor part and a fault factor, fault events that occur due to this fault, a rule ID associated with a rule including a condition part and a result part are registered in association with one another; an importance degree determination unit determining, when fault events of a new fault that is a newly occurred fault are registered with the database, degrees of importance of the fault events of the new fault based on at least one of values calculated through statistical processing or analytical processing for information other than the fault events or overall information about the fault events, which are registered with the database; and a rule generation unit generating a rule for the new fault based on the degrees of importance.

Abstract: A recovery assistance device according to an embodiment includes an analysis unit and a learning unit. The analysis unit generates a first procedure plan related to recovery work of a first failure by solving an optimization problem on the basis of first information related to the first failure. The learning unit acquires feedback information related to work procedure adopted for the recovery work of the first failure and generates a learning result reflecting the feedback information with respect to the first procedure plan. In a case where a second failure occurs, the analysis unit further generates a second procedure plan related to recovery work of the second failure using the learning result.

Abstract: A delivery plan creation device according to an aspect of the invention creates a delivery plan including an order of delivery of fuel to each of destinations using a delivery vehicle and an amount of fuel to be supplied. The delivery plan creation device includes a database, a storage unit, and a processor. The database holds environment information including destination information related to the destination and delivery vehicle information related to the delivery vehicle.

The processor includes an acquisition unit and a creation unit. The acquisition unit accesses the database to acquire the environment information and create an input condition that is a premise of the delivery plan from the environment information. The creation unit inputs the input condition to the neural network in which the trained model has been reflected to create the delivery plan.

Abstract: Provided is an event mapping acquiring unit (11) and an event type conversion unit (12). The event mapping acquiring unit (11) acquires an event mapping file defining a normalized alarm message indicating a normalized alarm content, a resource type indicating an event failure location, an alarm type, and an event type indicating event classification of the alarm in association with one another. The event type conversion unit (12) determines whether input alarm information matches the definition of the event mapping file acquired, when the input alarm information matches the definition, sets the event type to a value defined in the event mapping file, when the input alarm information does not match the definition, sets the event type to the alarm type of alarm information, and registers the event type and the alarm information in association with each other as a failure event in the database.

Abstract: In a failure location identification apparatus according to one embodiment, a facility information management unit records therein facility information including positional information of a physical resource, an external factor information management unit records therein external factor information concerning an external factor that possibly becomes a factor that causes a failure in the physical resource, the external factor information including positional information of the external factor, and a facility influence definition management unit records therein information concerning a possible influence of the external factor on the physical resource. A facility influence determination process unit identifies a failure occurrence location at which the failure is estimated to occur in the physical resource, from the facility information that is recorded in the facility information management unit and has positional information corresponding to the positional information of the external factor information, and outputs failure location information including information indicating the identified failure occurrence location, when it is determined that the external factor information recorded in the external factor information management unit influences the physical resource, on a basis of the information recorded in the facility influence definition management unit.
