摘要： PURPOSE: To support the generation of the operation plant of a system with many variables and many restrictions by storing a group of materials generated at a municipal water department as problem solution instances, retrieving solution instances of similar problems when a new problem is generated, and correcting and making good use of them by an applied instance base system. CONSTITUTION: The operation planning support system consists of an input device 101, a computation device 113, and an external storage device 118. The computation device 113 retrieves an operation instance meeting operation conditions by an instance retrieval part 106 when planning operation, and generates a draft of operation by the operation draft generation part 107 of an operation plan generation part 112. Further, the operation draft can be improved by a subprogram 108 for operation improvement of an operation plan improvement part 111 and proved by plural model program groups at a model execution part 109. Consequently, the operation planning operation can be supported effectively by the instance base system which uses a computer and made easy.

摘要： PURPOSE:To make development of a specific algorithm for planning unnecessary by a method wherein retrieval of working examples is made, based on problem circumstances and the result of execution on a model using an example, in a step of example retrieval, and a working plan is modified to suit itself to the problem circumstances. CONSTITUTION:A model program and a characteristic amount extracting program are actuated in order to evaluate how close do working examples and working plan match with a working strategy and conditions attached. In the first place, related examples are retrieved by means of index retrieval in an example retrieval step for retrieving an example suitable to conditions for planning of a working plan out of an example DB, and the result of a second retrieval is sought for the retrieved example. Based on the result of the output, an example serving as a base for the working plan is specified out of the examples outputted from the second retrieval in a step for producing the working plan suitable to the circumstances, and an initial data for the working plan is produced, based on the specification, with reference an to a monitoring-controlling system DB. Furthermore, final values are determined after improvement is made so that the contents of the working plan become suitable to the circumstances.

摘要： PURPOSE:To make an operating plan at a high speed in order to satisfy various operating conditions in a transport network where plural supply points are connected to plural consumption points. CONSTITUTION:Various conditions are set 11 for making a plan, and a distribution plan is calculated 12 in a fixed formula as a least cost flow rate problem. In this case, the least cost flow rate satisfies only the matter preserving conditions and the upper and lower limit levels of the pondage and the flow rate. Thus the least cost flow rate can be calculated at a high speed by a mathematical P1.80 method. However the least cost flow rate has a large time fluctuation of the flow rate and is inapplicable to the actual operation. In this respect, the solution is improved 13 with smoothing of the flow rate, etc., in order to satisfy various operating conditions. The plan value thus obtained is decided 15 by an operation planner. If the planner judges that the plan value is improper, the set conditions are varied and the same processing is repeated.

摘要： PROBLEM TO BE SOLVED: To prevent any misoperation to be generated due to the judgment mistake of an operator by communicating information such as caution on a plant operation to an operator without any misunderstanding. SOLUTION: Information registered by an operator is stored in storage devices 131-135 of a computer 100, and when the operator displays a monitor picture in order to perform a plant monitoring operation, the information stored in the storage devices 131-135 is synthesized with the monitor picture, and displayed on a CRT 151. Thus, it is possible for the operator to view the registered information, and it is possible to prevent any misoperation by the operator as a result.
