- Abstract
In this work, determination of the conditional ranking of aging sewer pipes was discussed using PROMETHEE and GAIA method. Pipe density in a drainage area, hydraulic capacity, flow velocity, and defect rate in each sewer section were considered as factors affecting the conditional ranking of the existing sewer pipes by PROMETHEE, which was compared with the sewer rehabilitation priority previously used in Seoul, Korea. In addition, GAIA plane was discussed as a tool to enable to visualize the correlation of alternatives, evaluation items, and weights. A method of so called 'GAIA cube', three dimensional extension of GAIA plane, was also suggested to reduce much loss of information from the original data set.
