水道広域化の効果の評価に関する方法論的研究

抄録

Area-wide waterworks are often planned to resolve water resources problem which cannot be solved by the single municipality. Improvement of water supply stability is one of the effects to be expected by areawide waterworks. Areal definition as a combination of municipalities should be planned in order to get a most effective alternative from view point of the stability improvement. This paper deals with evaluation method of the effect.
Indices are extracted to evaluate water supply stability. Design of experiment method is adopted to make alternatives of area-wide waterworks based on these indices. Factor profile method selects the most effective alternative. Case study gives a practical usefulness of this approach.
