Patent number: 5940817Abstract: To generate a problem solving plan and/or a system control plan respectively in association with the contents of the problem and/or the system operation conditions, there are disposed element knowledge for storing therein problem solving methods and system control guidelines and harmonizing knowledge for selecting and/or modifying the element knowledge. Depending on the contents of the problem and/or the system operation conditions, selections and modifications are executed on the problem solving methods and system control guidelines so as to produce an optimal problem solving method and/or an optimal system control guideline. Even when the solving method, the problem solving condition, and system executing situation vary depending on a given problem solving condition and a given system executing situation, an appropriate solving plan can be proposed.Type: GrantFiled: February 14, 1992Date of Patent: August 17, 1999Assignees: Hitachi, Ltd., Hitachi Information & Control Systems, Inc.Inventors: Kiyomi Kishi, Setsuo Tsuruta, Toshiya Oshima, Toshihiro Eguchi

Patent number: 5659734Abstract: On knowledge information processing and especially in a plan making system such as a system for generating schedule diagrams of trains and personnel, it becomes necessary to make or modify a plan by using a plurality of work stations when the plan becomes large-sized. At this time, the work stations are provided with equal plan making function. Thus, the work stations can divide planning responsibilities. Further, work stations are provided with priorities. Thus, management of competition among a plurality of work stations is facilitated and overhead caused by communication among a plurality of devices is reduced.Type: GrantFiled: October 10, 1990Date of Patent: August 19, 1997Assignees: Hitachi, Ltd., Hitachi Information and Control Systems, Inc.Inventors: Setsuo Tsuruta, Kiyomi Kishi, Kuniaki Matsumoto

Patent number: 5299287Abstract: A problem solving system including apparatus for representing a relationship between a goal including subgoals and its lower level subgoals and for achieving the goal as a strategy of a first kind. Apparatus is provided for repetitively dividing a goal including subgoals into its lower level subgoals according to the relationship between the goal and the subgoals. A strategy of a second kind is used to specify the functions to be performed by the apparatus to achieve the lowest subgoal. Apparatus is also provided for simplifying and solving a complicated problem by executing the goal including subgoals by use of the strategies of the first and second kinds.Type: GrantFiled: February 21, 1992Date of Patent: March 29, 1994Assignees: Hitachi, Ltd., Hitachi Control Systems, Inc., Hitachi Microcomputer Engineering Ltd.Inventors: Setsuo Tsuruta, Kiyomi Kishi, Kuniaki Matsumoto, Shigenobu Yanai, Kiminori Nakamura

Patent number: 4926343Abstract: This invention relates to a method of and a system for generating and correcting or regulating a transit schedule of a transportation medium, such as a train. Schedule tables for transportation media having numerical values for departure and arrival time, place of departure, transportation media and trainmen to be allotted and connection transportation media are correspondingly shown. Diagrams of plans are edited differently from the schedule tables, and diagrams of all or individual operations to be carried out by trainmen and other workers are all stored in a memory, and these diagrams are displayed in a display unit. Whenever variations occur in the schedules and actual transit condition is checked. Problems are eliminated automatically in a predetermined range of the diagrams, or picture and guidance displayed at once.Type: GrantFiled: October 11, 1988Date of Patent: May 15, 1990Assignee: Hitachi, Ltd.Inventors: Setsuo Tsuruta, Shoji Miyamoto

Patent number: 4779208Abstract: A computer system performs processing such as inference processing by sequentially executing rules each with its if-part stored in a working memory. The computer system comprises a production memory storing rules such as the laws of experience and nature and a working memory storing facts and hypothesis. The processing system processes the case where the rules include variables. To this end, this processing system groups the if-items and then-items which may be matched with each other depending on variable values, and takes representatives of the respective grouped items as association items to store the facts by the local parts of the association items.Type: GrantFiled: September 26, 1984Date of Patent: October 18, 1988Assignee: Hitachi, Ltd.Inventors: Setsuo Tsuruta, Shoji Miyamoto, Makoto Nohmi
