  • Patent number: 11891097
    Abstract: In the present invention, a resource management device receives transmission of a reservation request for a block section to be reserved from among a plurality of block sections included in a track traveled by a vehicle on the basis of track information which indicates the plurality of block sections and the connection relationships of the block sections. In a case where the block section to be reserved, as indicated by the reservation request, has not already been reserved by a vehicle other than the vehicle that transmitted the reservation request at the point in time when such reservation request was received, the following is recorded in a management table: that the block section to be reserved as indicated by the reservation request and a connection boundary between that block section and another block section are objects reserved for the vehicle that transmitted the reservation request.

  • Publication number: 20230229839
    Abstract: This verification processing device is provided with: an inspection unit that performs model inspection on an inspection target model including a plurality of elements; a selection unit that selects at least one of the plurality of elements included in a counterexample outputted as a result of the model inspection; and an exclusion history generation unit that generates exclusion history information indicating an exclusion frequency for each of the plurality of elements. The inspection unit further performs another model inspection on the inspection target model obtained by excluding the selected element. When another counterexample has been outputted as a result of another model inspection, the exclusion history generation unit increases the exclusion frequency of the selected element and updates the exclusion history information. The selection unit selects an element that is high in the exclusion frequency, on the basis of the exclusion history information.
