Abstract:
An operation control system according to an embodiment includes a ground system and an on-train system. The ground system is configured to be able to communicate with trains running on tracks and includes a first generation unit, a second generation unit, and a third generation unit. The first generation unit generates one or more first run curves predicted for one or more second trains each likely to be a preceding train or a following train with respect to a first train. The second generation unit generates a second run curve for the first train based on the first run curves, the second run curve preventing the first train from being influenced by and influencing running of the second trains. The third generation unit generates navigation for causing the first train to run in accordance with the second run curve. The on-train system is installed on each of the trains and includes a presentation unit configured to present the navigation.
Abstract:
According to one embodiment, an elevator includes an allocation control unit which uses one of group supervisory control techniques having different control indexes to allocate a car that responds to a destination floor registered by an operation of a landing call button in cars, a performance evaluation unit which performs performance evaluation of the group supervisory control technique based on an operating status of the cars, a scheduling unit which sets an elevator operation schedule representing a relationship between an arbitrary time zone and the group supervisory control technique applied to the time zone based on a performance evaluation result obtained by the performance evaluation unit in such a manner that the control indexes including passenger transport efficiency meet predetermined conditions, and a control switching unit which switches the group supervisory control technique in accordance with a time zone a current time belongs in compliance with the schedule.
Abstract:
An operation plan creation device according to an embodiment includes an operation plan creation unit. The operation plan creation unit includes an operation plan condition setting module, a run-curve condition setting module, a run-curve creation module, and an operation plan creation module. The run-curve creation module is configured: to acquire a first run-curve and a first energy consumption in respective inter-stop sections; to correct, when a total extension time length is set, run time lengths of the respective inter-stop sections based on the total extension time length; and to acquire a second run-curve based on the corrected run time lengths. The operation plan creation module is configured to create an operation plan based on the second run-curve.

Abstract:
[PROBLEM] To create a running curve which is closer to an optimum solution at high speed. [SOLVING MEANS] A running curve creation device of an embodiment is a running curve creation device to create a running curve which can make a train having a prescribed vehicle characteristic run between a prescribed departure station and a prescribed arrival station in a prescribed running time with a smaller cumulative energy consumption. A shortest time running curve creation unit creates a shortest time running curve in which the train runs between the stations in a shortest time, based on predetermined vehicle information and ground information of the train, and an energy saving running curve creation unit selects from the shortest time running curve and a plurality of solution candidates corresponding to states of the train at each prescribed elapsed time since the train has departed from the departure station, a solution candidate having the relatively small cumulative energy consumption in the prescribed running time, and creates an energy saving running curve based on the selected solution candidate.
