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.

Abstract: Provided are: a past relation identification unit that combines past sensor data with job data based on information on an item relating to data combination, and identifies a data relation between items based on an item of the past sensor data and an item of the job data; a real-time relation identification unit that identifies a data relation between items of real-time sensor data; a similarity calculation unit that calculates a similarity between the data relation identified by the past relation identification unit and the data relation identified by the real-time relation identification unit; and an output controller that outputs the data relation identified by the past relation identification unit and the data relation identified by the real-time relation identification unit while associating with each other by the item of the past sensor data and the item of the real-time sensor data, the similarity between those data relations exceeding a threshold, the similarity being calculated by the similarity calculation unit.

Abstract: To make a proposal of appropriate data preparation contents for a utilization purpose to a user making utilization of data, and to cause a system providing functions related to data accumulation, data preparation, and data utilization to have high importance level data preparation contents to be prepared for various purposes of various users, in such a manner as to enable facilitating the data utilization for various purposes using diverse data from a plurality of business systems, the system collates a utilization purpose designated by a user with data information prepared by the system, and calculates and presents data preparation content items to be carried out for the utilization purpose and a difficulty level of each item. The system aggregates the data preparation content items for the utilization purpose, categorizes similar data preparation contents, and calculates and presents an importance level of a category. The system creates a list containing processing programs, data definitions, and the like corresponding to the data preparation content items for the data preparation content category, and calculates and presents a usefulness of each item.

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.

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.
