  • Patent number: 11861353
    Abstract: Provided is a system update procedure planning apparatus capable of preventing an explosive increase in the amount of computation when solving an automatic planning problem in system update. The state element model simplification section 101 outputs a simplified state element model by applying a simplification transformation based on the unit affiliation information to the state element model. The automatic planning section 102 outputs an executable route, for the simplified state element model, from an initial state thereof to a target state. The internal transition completion section 103 converts the executable route from the initial state to the target state on the simplified state element model into the executable route from an initial state to a target state on the state element model before simplification.

  • Patent number: 11403270
    Abstract: An information extraction unit 82 extracts a set including pieces of predetermined information from a past search history for each change of a configuration requirement.

  • Publication number: 20220215449
    Abstract: In a parts configuration plan generation device, a concretization processing unit (first concretization unit) concretizes an “abstract configuration” by using a first concretization pattern, and thereby generates a “base parts configuration”. A concretization processing unit (second concretization unit) applies a second concretization pattern to the base parts configuration and concretizes a parts item contained in the base parts configuration, and thereby generates a “candidate parts configuration”. An output unit outputs, as a “parts configuration plan”, the candidate parts configuration where concretization is done and satisfying a condition to be satisfied by a device to be built.

  • Patent number: 11296965
    Abstract: An abnormality detection method is provided. The abnormality detection method is for detecting an abnormality that may be transmitted to a bus in an on-board network system. The on-board network system includes a plurality of electronic controllers that transmit and receive messages via the bus in a mobility entity. In the abnormality detection method, for example, a gateway transmits identification information to a server and receives a response determining a unit time. An operation process is performed using feature information based on a number of messages received from the bus per the determined unit time and using a model indicating a criterion in terms of a message occurrence frequency. A judgment is made as to an abnormality according to a result of the operation process.
