  • Patent number: 11836657
    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.

  • Publication number: 20220340182
    Abstract: A plurality of simulations executed by a plurality of simulators, respectively, coupled to one another to perform communication are executed efficiently and fast as a whole when executed in cooperation. An information processing system stores execution order information that is information indicating execution orders of the plurality of simulations. Each of the simulators generates output data by executing a corresponding one of the simulations based on input data that is data input at execution start, and execution control of the other simulations is performed when the simulation has reached a check point at a time point halfway through execution of the simulation. The check point is set based on, for example, a viewpoint of time or a viewpoint of situation of the simulation.

  • Publication number: 20190318253
    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.

  • Publication number: 20160267417
    Abstract: A plan coordination system includes a processing device configured to perform: processing that generates public data from definition data of plans, receives definitions by a user for information coordinated between plans among process procedures indicated by the public data, applies the definitions by the user to the definition data of the plan, and generates a plan coordination model; processing that notifies the data to a management device of another plan as a coordination destination in the coordination relation at a change event on the definition data, changes the plan coordination model based on a generation result of the other plan reflecting the change event, and notifies the changed data to the management device of the other plan having the coordination relation with the plan changed along with this change; and processing that outputs a generation result of each plan when planning is completed for all plans.

  • Publication number: 20130318002
    Abstract: A resource management plan creation support device reads in a travel schedule, represents, as one node, each path from an originating location to a terminating location of each leg included in a travel schedule that has been read in, and creates a network model by connecting together, using links, the legs over which consecutive travel is possible based upon the place and time. In addition, nodes representing auxiliary resources are added to the created network, and the network model is updated by adding links representing temporary usage of the auxiliary resources or temporary cessation of use of business-use resources. Also, by finding a path group encompassing each node of the network model so as to satisfy a pre-supplied condition (the condition of allocating resources to all of the legs), a management plan for resources which execute transport services is created.
