  • Patent number: 11914348
    Abstract: A plant operating condition setting support system for supporting the setting of an operating condition of a plant that performs a process formed by devices includes: control devices that subject controlled devices to feedback control respectively; and an operating condition setting support device that provides integrated support for the setting of the control devices, which perform feedback control tasks respectively and independently. The operating condition setting support device includes: a measured value multiple acquisition unit that acquires measured values indicating states of the controlled devices, respectively; and a control device adjustment parameter determination unit that determines, based on the measured values acquired, control device adjustment parameters used by each of the control devices to determine manipulation variables for control that should be input to the controlled devices, according to a policy learned by deep reinforcement learning.

  • Patent number: 11188762
    Abstract: There is provided a moving body risk assessment device including a moving body detection unit that detects presence or movement of a moving body within an imaging range on the basis of image information imaged in a wavelength region different from a visible region, and a risk assessment unit that assesses a risk to the detected moving body from the image information and a result of the moving body detection obtained by the moving body detection unit.
