Abstract: A new method used to evaluate the entity behavior trustworthiness in distributed GIS is discussed. This paper puts forward the ordered hierarchical structure model. The acquirement and standardization of evidences are discussed. The Fuzzy Analytical Hierarchy Process(FAHP) is used to decide the weights of all evidences and attributes. The whole entity behavior is evaluated based on the discussion. An example and the conclusion analysis are given. The evaluation method makes it scientific to decide the weights and easy to carry out evaluation.

Key words: distributed GIS, entity behavior, Fuzzy Analytical Hierarchy Process(FAHP), evaluation of trustworthiness

摘要： 提出一种新的分布式GIS中访问实体行为可信度评估方法，介绍访问实体行为证据的信任化和归一化方法，给出访问实体行为可信度评估层次结构模型，用模糊层次分析法(FAHP)原理确定各访问实体行为证据和特性的权重，对可信度进行整体评估。通过实例说明评估过程并对结果进行分析。证明该评估方法能够科学地确定各访问实体行为证据和特性的权重，易于实现访问实体行为可信度评估。
