摘要： PROBLEM TO BE SOLVED: To reduce the required storage capacity by providing the high-quality solution on the early stage of search by deciding the transient destination of current state by evaluating the adjacent state of state space corresponding to the sum of a state change cost function value and the evaluation function value of the adjacent state. SOLUTION: The state to be the start point of state space search is initially set to the current state (concerned state) and its evaluation function value is calculated (1). Afterwards, the states transitable from the current state are extracted and their evaluation function values are respectively calculated (4). When any state requiring the change of its evaluation function value exists among the extracted states, that evaluation function value is changed (5). Further, the adjacent extracted state is evaluated corresponding to the sum between the total sum of values of elements of state change cost function value vectors corresponding to the elements having difference between that state and the current state and the evaluation function value of the adjacent state and the state having the smallest evaluation function value is selected as the best adjacent state (the next concerned state) (6). Thus, the adjacent state is evaluated so that the transient destination of current state can be decided.

摘要： PURPOSE:To prepare a high-quality daily generating plan of a hydraulic power plant group using the simple software of a computer by automatically preparing a plurality of plans by repeatedly operating a generating plan preparing means, generating plan evaluating means, and generating plan preparing condition reviewing means and selecting the best plan by evaluating the plurality of plans by comparison. CONSTITUTION:A generating value correcting factor initializing means 1 sets generating value correcting factors corresponding to each discharge route, time zone, and used water quantity per unit time to '1.0'. A generating plan preparing means 2 prepares generating plans at every dam by successively performing water distribution from the discharge route, time zone, and used water quantity per unit time which are largest in (generating value per used water quantity X generating value correcting factor) until the total quantity of distributed water reaches a daily used water quantity. A generating plan evaluating means 3 evaluates the prepared plans and preserves the best plan by simulating a water system based on the generating plans of all dams. A generating plan reviewing means 4 changes the correcting factor based on the result of the simulation.
