Abstract: A schedule change apparatus includes a change model creation section, a schedule creation section, a schedule change evaluation indicator creation section, a production simulator, and a control section. The change model creation section creates a change model estimating a portion of the schedule to be changed. The schedule creation section uses the schedule change model to generate proposed schedule changes and generate a proposed alternative schedule. The schedule change evaluation section generates a schedule change evaluation indicator indicating a best value for a proposed schedule change. The production simulator implements simulation with a simulation condition changed on a basis of schedule execution status information and equipment operation status information for the day and calculates values of the schedule change evaluation indicator for the proposed alternative schedule candidate group on a basis of the schedule change evaluation indicator already learned. The control section outputs a proposed schedule change.

Abstract: An operation plan change assistance system includes a determination model generation unit configured to generate an operation plan change determination model that receives information about a train operation content before a certain point in time and information about a change in an operation plan executed before the point in time and outputs information about a change in operation plan to be executed next; and an operation plan change proposal creation unit configured to input information about a train operation content before a point in time designated by a user and information about a change in an operation plan executed before the designated point in time, create change candidates that are candidates for each change in an operation plan to be executed in stages after the designated point in time, specify a change candidate that satisfies a predetermined condition, and create the specified change candidate as an operation plan change proposal.

Abstract: Proposal of data analysis components is enabled to be performed irrespective of the quantity of an implementation history of data analysis, and thus efficiency and cost reduction of production of software for data analysis are promoted. A data utilization platform server 101 is configured to includes a arithmetic device 112 which executes processing of generating analysis relationship information prescribing linkage between analysis target data and an analysis component executing analysis processing for the analysis target table on the basis of a relationship among a plurality pieces of the analysis target data collected from a plurality of predetermined systems; and processing of specifying a combination of a plurality of the analysis components available for predetermined data designated as an analysis target by a user on the basis of the analysis relationship information.

Abstract: Provided is a service plan change assistance apparatus (110) including: a storage apparatus (13) that stores a decision model in which a service status of each of a delayed train and a to-be-delayed train to be delayed due to the delayed train and train service plan change content for recovering a delay of the to-be-delayed train are associated with each other, in association with a station at which the to-be-delayed train is delayed due to the delayed train; and an arithmetic apparatus (11) that estimates a future train service status based on a train service plan and a train service record before a current time, identifies, from the estimated train service status, the station at which the to-be-delayed train to be delayed due to the delayed train is standing, inputs information on the estimated train service status to a decision model associated with the identified station to create a service plan change proposal that includes information indicating train service change content for recovering the delay of the to-be-delayed train, and outputs the created service plan change proposal.

Abstract: Provided is a resource operation planning assistance apparatus for automatically generating a change tendency from a past resource operation planning change history, using the change tendency to generate a solution proposal to an inconsistency in a resource operation planning, and presenting the solution proposal together with a priority order. The resource operation planning assistance apparatus includes: a schedule candidate creation unit configured to create a schedule candidate of each resource; a history learning unit configured to learn an operation planning history in advance to generate a schedule change rule; a schedule candidate list creation unit configured to create a schedule candidate list for an operation planning target resource; a planning creation unit configured to create, with respect to at least one violation included in an operation planning, an operation planning for solving the violation; and an operation change content display unit. The resource operation planning assistance apparatus is configured to apply the schedule change rule created by the history learning unit in advance to the schedule candidates created by the schedule candidate creation unit to calculate an adoption rate for each schedule candidate. The operation change content display unit is configured to display the operation planning created by the planning creation unit in a priority order by using, as input, the schedule candidate list for each resource created by the schedule candidate list creation unit.

Abstract: A data analysis support apparatus includes: a relationship network generation section that analyzes a relationship between operating systems, a relationship between operation data tables, a relationship between data items possessed by the operation data tables and a relationship between data values possessed by records of the operation data tables and stores them, as a relationship network; a data item classification section that classifies data items that become a data analysis target into a first data type based on an actual value and a second data type based on a planned value or a pre-definition; an analysis data table generation section that generates and accumulates an analysis data table to be used for data analysis; a data model generation section that generates, as a data model, a data item group that allows data analysis in combination; and an analysis target item presentation section that recommends a data item to be made an analysis target.
