Abstract：A comprehensive method for evaluating pumping station buildings safety was studied by using the standard genetic algorithm (GA), analytic hierarchy process(AHP) and fuzzy evaluation method so as to assess the buildings more precisely. Firstly, the numerical values for evaluating pumping station buildings safety were obtained and then a fuzzy comprehensive evaluation matrix was established by using the comprehensive integration method from qualitative to quantitative and by considering expert knowledge, inspection data and all other information. Secondly, the weight vector to evaluate index was determined with the standard genetic algorithm and AHP. Finally, the fuzzy comprehensive evaluation model was generated, through which a result of pumping station buildings safety evaluation could be worked out. For the buildings in Linhong west pumping station, the fuzzy comprehensive evaluation resultant vector is S=(0.313 6, 0.356 2.0.247 1,0.083 1); according to the maximum membership degree principle, Smax is 0.356 2, which corresponds to the 2nd commentsafe basically, thus the buildings in that station fall into the 2nd Class. This suggests that the buildings of that station meet the design standards and the safety requirements for operation as a whole. This conclusion is consistent with the one obtained by using usual evaluation methods, indicating the fuzzy comprehensive evaluation model is feasible.
