  • Patent number: 11814090
    Abstract: A railroad system includes a plurality of trains and an operation management device. The operation management device manages operation of a subject train that is at least one of the plurality of trains. The operation management device includes a calculation unit and a communication unit. The calculation unit calculates a target arrival time at which the subject train is to arrive at a next station, upon occurrence of an arrival delay of a preceding train at the next station, the preceding train being a train among the plurality of trains and running ahead of the subject train; and, upon arrival of the preceding train at the next station, calculates a target arrival time at which the subject train is to arrive at the next station. The communication unit transmits, to the subject train, information on the target arrival time calculated by the calculation unit.

    Abstract: An execution sequence decision device is capable of efficiently and appropriately determining the execution sequence of processing modules even in a case where those have a closed circuit in the input/output dependencies. A dependence evaluation sub-unit and an anti dependence evaluation sub-unit evaluate the dependence and anti dependence of each processing module in a processing module group. A priority evaluation sub-unit determines the priority of each processing module in the processing module group based on the dependence and anti dependence. An execution order allocation sub-unit allocates the top of execution sequence to one processing module that has the highest priority obtained by the priority evaluation sub-unit.
