  • Publication number: 20160321213
    Abstract: A computer utilizes correlation matrix data including a value indicating correlation between indicators and comprises a graph process unit that includes a control factor calculation unit configured to calculate a control factor for generating compressed graph data based on a constraint condition on a process; and a graph generation unit configured to generate graph data from the correlation matrix data by using the control factor. The control factor calculation unit obtains a target process time as the constraint condition; calculates a maximum of a number of edges to be included in the graph data; calculates a threshold for extracting the elements converted from the correlation matrix data to the graph data based on the maximum of the number of edges; and outputs the threshold as the control factor. The graph generation unit extracts the elements from the correlation matrix data based on the threshold, and generates the graph data.

  • Publication number: 20150324482
    Abstract: A decision-making support system which is a client-server system comprising: multiple servers; a client having a display; a network; and a database. On the basis of data acquisition conditions supplied via the client the multiple servers acquire from the data base on multiple distributed processing platforms, a first data group spanning from the past to the present, and generate a first network graph for the time from the past to the present. The multiple servers also execute multiple simulations based on the first data group, on the basis of provided simulation conditions, and generate second and third network graphs for a time not included in the first data group or for the future. The client receives the results of the generation of these network graphs and displays on the display the first through third network graphs spanning from the past to the present, and to the future, thereby providing the user with a scenario map.
