  • Patent number: 11573541
    Abstract: An objective of the present invention is to provide a future state estimation method and future state estimation device with which, given that the space in which the estimation is carried out is finite, it is possible to rapidly estimate the states of a controlled object and the peripheral environment thereof in the form of probability density distribution for infinite future.
    Type: Grant

  • Patent number: 7526353
    Abstract: A sequence design support system is used to support a design of a sequence control program which controls a flow path condition of a fluid in an apparatus and piping system which is constructed connecting apparatus such as a valve with piping and comprises a valve pattern plan generation unit which generates a valve pattern plan which is plan data showing the flow path condition per time step of the fluid in the apparatus and piping system from apparatus and piping system plan data which is plan data showing the apparatus and piping system and time chart sheet which is obtained defining the condition of the apparatus in the apparatus and piping system per time step.

  • Patent number: 5347614
    Abstract: A knowledge processing system structurizing method and tool. By preparing a general-purpose search program on the basis of information inputted by the user, an inference program for a given problem to be solved and a given object domain is created. The general-purpose search program is constituted by a plurality of search elementary functions. A guide message is displayed on a display unit in accordance with classified information of a problem solving strategy. Program creating knowledges are obtained from the information inputted by the user in response to the guide message. By employing the program creating knowledges, a general-purpose program is created with the aid of a correspondence table containing correspondences between search elementary functions having search primitive functions built therein and search fundamental functions.
