摘要 在对模糊度分析的基础上,研究了地理目标位置与属性不确定性的集成度量策略,提出了基于四元组(x,y,A, D) 的能集成表达位置和属性不确定性的模糊点、模糊线和模糊面的形式化描述方法。以模糊度曲面在建设项目选址空间决策中的应用为例,探讨了基于该形式化描述方法的模糊分析应用。实验结果表明,该形式化描述方法是一种有效集成位置与主题属性不确定性的方法。 This paper designs a formalized description model based on the quartuple (x, y, A, D), which integrates the positional and thematic uncertainties of the fuzzy point, fuzzy line and fuzzy region. On the basis of the model, this paper gives a case of the site selection of real estate development to test that the representation method is apt for fuzzy analyses and computation.
