  • Patent number: 9910412
    Abstract: A state control device is arranged for each function block. When acquiring from a function block (Bi) a state (?) representing a state of the function block (Bi), a state control device (Ci) corresponding to the function block (Bi) acquires a value (Ui) and a value (Vi) based on an evaluation function (fi) convex upward or downward depending on the performance of the function block (Bi), and transmits the value (Vi) to a state control device (Cj). When receiving from the state control device (Cj) a value (Wj) which the state control device (Cj) has acquired similarly to the value (Vi), the function block (Bi) is controlled based on the value (Ui) and the value (Wj).

  • Publication number: 20170091307
    Abstract: A creativity aiding server selects nodes from among a plurality of nodes included in a tree diagram that is generated according to nodes each representing an opinion created by each user to derive a solution to a problem dealt with in a discussion and links each representing relevance between the nodes, by tracking links backward from a solution node representing the solution to an assignment node representing an assignment, the selected nodes being included between the solution node and the assignment node. The creativity aiding server calculates a degree of contribution made by each of the selected nodes in deriving the solution, by using types of the selected nodes and types of the links. The creativity aiding server identifies one or more of the nodes of which the degree of contribution is equal to or higher than a threshold value.
