Abstract: An office information system having a plurality of work stations connected via a network to mutually exchange electronic mails each includes a control information definition unit for defining control information representing what kind of processing can be performed on mails after reception, a processing log memory unit for storing log information of operations which have been performed on a received mail, a control unit for guiding a receiver by referring to both the control information and log information, a task tracking instruction unit for inquiring the processing status of mail, and a task tracking unit for reporting the status in response to such a tracking instruction. The system stores and interprets control information relating to the flow of an OA object on the network, which has been conventionally involved in the memory of an office worker, and guides the office worker to work to be done by the office worker.

Abstract: A planning method by computer support is based on a planning program using data concerning an object to be planned and data necessary for planning. The planning method comprises the steps of reading out of a memory various kinds of data concerning the object to be planned; preparing a plan by using the data in accordance with the planning program; delivering results of the prepared plan; inputting definition data for an explaining statement concerning the planning results and data concerning an output form of the explaining statement; processing the planning results on the basis of the definition data for the explaining statement and the data concerning the output form to prepare an explaining statement concerning the planning results; and delivering the prepared explaining statement.

Abstract: The computer aided planning support system of this invention is constructed of a planning information input device from which an object data for making a plan is inputted; an object data storage unit for storing the inputted object data; a planning unit for making a plan by reading the object data stored in the object data storage unit and processing the read-out data in accordance with a planning program; a planning data storage unit for storing the data associated with the plan made by the planning unit; a planning data processing unit for processing the planning data stored in the planning data storage unit in accordance with a predetermined scheduling function and sending the processed data to the planning unit; and a planning information output device for outputting the planning result generated by the planning unit in the form a user can use it.

Abstract: In a method for determining an optimum scheduling in a computer-aided scheduling system the data associated with a schedule to be generated is previously stored in a memory data. A strategy decision table showing therein one or more scheduling strategies suitable for a plurality of the states in a scheduling process is prepared. An optimization definition table indicating degree of improvement precedence or precedence order of the scheduling strategies of the evaluation items, where degree of improvement precedence is defined as degree of improvement of evaluation value of he evaluation item in changing of the scheduled strategy, is prepared. A schedule is generated by repetition of selecting and executing the scheduling strategies by using the strategy decision table. The other schedules are generated by changing the scheduling strategy selected in the state of the scheduling process by using the optimization definition table. An optimum schedule having the best evaluation value is selected.
