    Abstract: A method and an apparatus for easily and efficiently setting an evaluation index suitable for an evaluation purpose when a business or a business portfolio is evaluated. In the method and apparatus, investment distribution is easily and visually confirmed during computation of the evaluation index when an object to be computed is the business portfolio. A table for defining a computation expression model for the evaluation index and a correspondence relationship between the evaluation index and the evaluation purpose is managed by a database to extract and provide an evaluation index model conforming to the evaluation purpose specified by a user.

  • Publication number: 20020178033
    Abstract: An automobile insurance premium setting system is provided in which a premium amount may be appropriately set according to driving states of an insurant's automobile. A basic premium calculated based upon coverage and indemnity specified by the insurant, and an additional premium estimated based upon driving behavior submitted by the insurant are added and collected as a provisional premium. Driving behavior points are counted each time when actual driving behavior of the insurant deviates from criteria determined based upon the driving behavior. Safe driving points are counted each time when the actual driving behavior deviates from safe driving criteria submitted to the insurant in advance. The driving behavior points and the safe driving points are combined into demerit points, to calculate an actual additional premium corresponding to the demerit points, and a difference between the estimated additional premium and the actual additional premium is balanced upon expiration of the automobile insurance.
