摘　　要：在复杂系统的综合评价过程中,为客观地反映模糊因素的影响并增强决策的柔性,建立了一种新的直觉模糊综合评价模型.在构建多层次评价指标体系的基础上,用直觉模糊区间表示专家对方案优劣的判断,结合决策者的风险态度得到方案的评价结果.直觉模糊综合评价模型更为合理地表示了专家的主观判断,在风险投资决策中的应用实例表明了该模型的实用性和有效性.In the process of comprehensive evaluation for complex system, a new intuitionistic fuzzy com- prehensive evaluation model is built to reflect the influence of fuzzy factors objectively and to enhance the decision flexibility. Based on the multi-layer risk evaluation index system, the evaluation results is ob- tained, where the expert judgment is represented by intuitionistic fuzzy interval and the decision maker＇ s attitude is considered. Then the expert judgment is represented by the intuitionistic fuzzy comprehen- sive evaluation model and the practicability and validity of the proposed model is illustrated by the practi- cal applications on risk investment decisions.
