Abstract: A statistical model of a delay time of each mobile body to a plan schedule is generated in a predetermined section on the basis of the plan schedule, an actual schedule that is a daily travel result of the mobile body, and actual values of delay factors in a chronological order, at least either of past result analysis processing of classifying a first delay time that is a delay time of the mobile body into second delay times that are delay times of the delay factors of the mobile body on the basis of the generated statistical model and the actual values of the delay factors and future prediction analysis processing of predicting a third delay time that is a delay time of a requested mobile body on the basis of the statistical model and assumed values of the delay factors with respect of a new plan schedule is executed.

Abstract: An timetable plan creation system 100 includes: a storage device 101 that stores information regarding a constraint that is generated in each of timetable variables of an timetable plan and regarding the intensity of the constraint, information that associates a creation algorithm of the timetable plan and a measure of an evaluation index improved by a timetable variables of the timetable plan and by the creation algorithm, and information on desired change of the intensity of the constraint; and a computing device 104 that generates a constraint that has an intensity and that is generated for each of the timetable variables of the timetable plan, and that selects a plan creation algorithm for improving the quality of the timetable plan, and that creates a new timetable plan by executing each of selected plan creation algorithms to which the generated constraint is applied.

Abstract: Disclosed is a resource management planning support device 1 including a learning information storage section (storage section 13), a duty recommendation processing section 110, a planning processing section (operation rescheduling planning processing section 120), and a screen processing section 140. The learning information storage section stores plan result information regarding existing operation rescheduling plans. The duty recommendation processing section 110 exercises a prior learning function to generate a duty recommendation model for recommending a duty. The planning processing section exercises a planning function to create an operation rescheduling plan by selecting a duty template suitable for a planning target train set according to the duty recommendation model generated by the duty recommendation processing section 110. The screen processing section 140 outputs a plan result display screen 147 for displaying the operation rescheduling plan created by the planning processing section.

Abstract: A train operation support system for outputting a rescheduled timetable for a planned timetable of a train from a computer by using the planned timetable and an actual timetable of the train includes a timetable modification unit that modifies the planned timetable by using a given timetable modification method, a passenger flow prediction unit that calculates passenger staying information containing information indicating the number of staying passengers in each time zone at each station, by using demand information indicating a destination of a passenger in each time zone at each station where the train stops, a timetable rescheduling unit that modifies the demand information in reference to the planned timetable modified by the timetable modification unit, inputs the modified demand information to the passenger flow prediction unit, and creates the rescheduled timetable for the planned timetable by using the passenger staying information output from the passenger flow prediction unit, and an output unit that outputs the rescheduled timetable created by the timetable rescheduling unit.

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: A timetable planning system 1 includes a storage device 13 and a computing device 11. The storage device 13 stores evaluation index improvement degree information 320 that stores relations between a change of each constituent element of an operation timetable on one hand and a change in quality of the operation timetable resulting from the change of each constituent element in terms of each operation timetable viewpoint on the other hand. The computing device 11 performs a changeable timetable element selection process of selecting the operation timetable constituent element that most improves the quality of the operation timetable, in reference to the evaluation index improvement degree information, an optimization model selection process of selecting, from among multiple timetable generating models each capable of generating the operation timetable, the timetable generating model that most improves the quality of the whole operation timetable through the change of the selected constituent element, and a timetable optimization process of generating a new operation timetable based on the selected timetable generating model.

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.
