  • Publication number: 20200363792
    Abstract: A support system displays, on the basis of management information as a past record which shows, for each product loaded in a production system in which a plurality of different models of products are loaded and a sequential order of two or more of a plurality of steps is different depending on the model, an execution time of each of the steps, at least one of a first holistic chart (having a time axis and showing a feature value of production situation of the product during a display target period on a per predetermined unit basis) and a second holistic chart (showing a relationship between a plurality of steps with respect to a flow of a plurality of models of products). The support system selects at least one of a model and a step for one of the holistic charts, and displays step element information.

  • Publication number: 20200104542
    Abstract: A simulation results evaluation device applies plural numbers of virtual input parameters (VIPs) of a simulation test of the power generation facility to model data showing virtual behaviors of the power generation facility. The device calculates each of virtual process values (VPVs) with respect to each of the VIPs and a score obtained by multiplying the VPV by a coefficient of a positive value when the VPV is included in a predetermined target range, the coefficient being set for each of the VPVs, the coefficient being assigned such that as a deviation from a predetermined target becomes greater, the value of the coefficient becomes smaller, or a coefficient of a negative value when the VPV is included within a permissible range provided adjacently to the predetermined target range. The device extracts a simulation test condition that satisfies a predetermined evaluation condition based on the calculated score.

  • Patent number: 10471760
    Abstract: A multiple-image display body includes a spacer layer, a line tone barrier layer stacked on the first surface of the spacer layer, and a multiple-image formation layer stacked on the second surface of the spacer layer. The line tone barrier layer includes first regions, which transmit electromagnetic waves, and second regions, which absorb electromagnetic waves. The multiple-image formation layer includes images that are visible when observed from specific angles over the first regions of the line tone barrier. The image is formed by a contrast resulting from an area ratio of the third region, which scatters electromagnetic waves, and the fourth region, which absorbs electromagnetic waves.
