Abstract:
According to the rural safe drinking water projects in Xianyou district of Mianyang city in Sichuan Province, a fitness evaluation model for the safe drinking water projects in the rural areas based on the user demand was established using the methods of factor analysis and analytic hierarchy process (AHP). The weight coefficients of the second-grade indexes with regard to the first-grade indexes were determined by the contribution rate of the common factor extracted from factor analysis, and the. weight coefficients of the third-grade indexes with regard to the second-grade indexes were determined by the subjective weight from AHP and objective weight from factor analysis. The results showed that the reasonableness of water fee standard, the convenience of access to drinking water resource, and the reliability of quality of engineering construction management are the main factors affecting the fitness. The model results were similar to the actual survey results, which suggested that the fitness evaluation model based on the user demand is applicable to guide the evaluation of safe drinking water projects in the rural areas.
