模糊综合评价法是一种基于模糊数学的综合评判方法。本文针对美学评价的影响因素具有模糊性这一特征,运用模糊数学的理论,对马鞍山大桥进行美学论证,将桥梁景观影响因素分成若干个指标,建立了评价指标集、隶属函数和权重集,通过层次分析法计算评价指标的权重集,由加权平均模糊算子对评价指标作综合模糊运算,评价大桥整体景观。实例表明:模糊综合评价方法可操作性强、效果较好,可在桥梁景观评价中广泛应用,同时从科学的角度证实了马鞍山大桥美学设计的成功。
Fuzzy comprehensive evaluation method is a comprehensive evaluation method based on fuzzy mathematics. In this paper, aiming at the fuzziness of the influencing factors of aesthetics evaluation, this paper applies the theory of fuzzy mathematics to the aesthetic demonstration of the Ma’anshan Bridge, divides the influence factors of the bridge landscape into several indexes, sets up the evaluation index set, membership function and weight set, Analytic Hierarchy Process (AHP) is used to calculate the weight set of evaluation indexes. The weighted average fuzzy operator makes comprehensive fuzzy evaluation of the evaluation indexes to evaluate the overall landscape of the bridge. The example shows that fuzzy comprehensive evaluation method is feasible and effective and can be widely used in bridge landscape assessment. At the same time, the success of aesthetics design of Ma’anshan Bridge was confirmed from a scientific point of view.
