Composition and application of autonomous decentralized scheduling system for discharge management of shallow well groups: optimization for discharge management of shallow well groups (2)

摘要

The extensive groundwater management of a wide basin requires utilization of a combinational optimization method in conjugation with groundwater dynamics to make the most appropriate management, so as to solve problems of competition and cooperation for the limited conditions such as water light. The proposal for evaluation method of hydraulic characteristics including "safe yield capacity" of shallow wells (diameter: 3-5m, depth: 8-15m) has already been described in the previous work as the fundamental study of this research. In this study, more than 40 shallow wells were divided into several groups. Each group consists of several adjoining wells with its own "group safe yield capacity" and is regarded as subsystem. We treated the discharge management as a scheduling problem among autonomous decentralized subsystems and proposed the water volume allotment method based on the quantitative elements, such as working time and idling time, figured by human expert. Moreover, the method was embodied in the form of three steps appropriate algorithms of the scheduling system among subsystems. An applicability of this method was shown by an example.
