基于模糊综合评判的汽车选购决策

摘要

汽车选购是一个复杂的、模糊的决策性问题，应用改进层次分析法构建了汽车选购决策体系，确定了评价指标权重，并应用二级模糊综合评判模型将汽车选购问题进行条理化与量化分析。结果表明，该模型合理可靠，为汽车选购决策提供科学依据。%The car purchase decision is a complex and fuzzy decision problem. The decision-making system of purchasing cars is established based on the improved AHP. The fuzzy synthetic evaluation model weights determination problem was solved. The two-level fuzzy synthetic evaluation model is established based on fuzzy mathematical theory,which makes a car purchase question systematic and quantizing. The results show that the fuzzy evaluation is a rational, and reliable method for automobile purchase decision.
