| 摘要: |
| 为解决通信卫星效能评估问题，提出一类基于模糊理论的评价模型.利用模糊理论的思想，通过对评价对象的性质分析，建立了一个适用于一类评价对像的非线性评价函数.这类对象的每一个评价指标由一系列因素所决定，并且这些因素之间是相互关联的，但任意两个指标之间是相互独立的.利用模糊聚类分析方法，本模型还可以对若干同类型的对象进行分类.最后，基于具体数据，利用本模型给出东方红系列通信卫星的效能评估，东方红3号、4号基本型、4号增强型和5号的评估得分分别为0.230~0.243、0.470~0.536、0.614~0.791和0.855~0.945.评估结果表明，东方红系列通信卫星的整体效能是一直呈上升趋势的，但综合来看东方红5号的整体效能并没有比东方红4号增强型高出过多.

| Abstract: |
| An evaluation model based on fuzzy theory is proposed in order to study the effectiveness evaluation of telecommunication satellites. Using ideas from fuzzy theory, a nonlinear evaluation function is established based on the analysis about properties of the assessment objects, making our model be applicable to a class of assessment objects which are evaluated by a system of index determined by a constellation of factors. These factors may be mutually dependent on each other. However, any two indices are independent. Given a number of such objects, the model is also able to classify them by using the method of fuzzy cluster analysis. Finally, the effectiveness evaluation of telecommunication satellites is considered according to the measurement data. The scores of the telecommunication satellites, Dongfanghong Ⅲ, the basic and enhanced type of Dongfanghong Ⅳ and Dongfanghong Ⅴ are 0.230-0.243, 0.470-0.536, 0.614-0.791 and 0.855-0.945 respectively, which shows that the effectiveness of Dongfanghong telecommunication satellites are growing. However, the integrated efficiency of Dongfanghong Ⅴ is not much better than that of the enhanced type of Dongfanghong Ⅳ.
