Abrégé

A train control system determines whether deterioration in performance of a sensor for obstacle detection is temporary and allowable from the viewpoint of ensuring safety of train travel or is not negligible from the viewpoint of safety. The train control system has sensors, and an on-board control device that includes a database in that records ground installation objects existing along a travel path of a train, positions of the ground installation objects, and weights set for the ground installation objects. When the sensors detect a ground installation object, the on-board control device collates the detected ground installation object with those recorded in the database, determines that a ground installation object that exists in the database but cannot be detected by the sensors is an undetected ground installation object, calculates a weight for the undetected ground installation object based on information of the database, and determines whether the sensors are abnormal.

Abrégé

A distributed energy resources management system decomposes an optimization problem that minimizes or maximizes a cost index of distributed energy resources into a master problem having a linear constraint and a subproblem having a nonlinear constraint, the optimization problem being created from power system topology information, coupling busbar information on the distributed energy resources, and facility information on the distributed energy resources obtained from an energy resources management system. The distributed energy management system further estimates a new constraint condition for the master problem based on sensitivity information in a dual problem of the subproblem, adds the new constraint condition to a constraint condition of the master problem to limit a search area for a solution of the master problem, and computes a range of output combinations of distributed energy resources. The distributed energy management system further solves an optimization problem defined as the master problem based on the range of output combinations to calculate power generation amounts of the distributed energy resources, and outputs the calculated power generation amounts to the energy resources management system.

A manufacturing network processing system (100) is provided with a processing unit (51) that causes a terminal device (60) to display a manufacturing network in which a process by which components are assembled or materials are processed sequentially to complete a prescribed product is represented by a tree-structured network. Each node of the manufacturing network is associated with an item code for a component or material serving as a constituent element of the product. Each branch of the manufacturing network is associated with a drawing code of a drawing used for assembling the components or processing the materials. When there is a prescribed inconsistency in the manufacturing network, the processing unit (51) causes the terminal device (60) to display a notification screen (601) for the inconsistency.
