中文摘要：

激光通信系统需要评价和定量分析，且存在多个评价指标。针对评价指标的模糊性、相对性和多样性，为了对激光通信系统进行定量评价，采用灰色系统理论中的灰色聚类分析法。首先对具有模糊性和相对性的评价指标进行灰量白化，然后将激光通信系统按照聚类指标进行灰色聚类，计算不同激光通信系统所有指标的综合聚类效果，最后以聚类类型作为各系统定量评价的依据。该方法将多指标决策问题转换为单一指标决策问题，它是一种定量评价激光通信系统的新方法。

英文摘要：

Laser communication system needs evaluation and quantitative analysis and it has multiple criteria. In consideration of the fuzziness, diversity and relativity of evaluation criteria, the grey cluster method in grey system theory was introduced to evaluate laser communication system quantitatively. Firstly, the evaluation criteria with fuzziness and relativity were whitened, and then all the laser communication systems were clustered by clustering criteria and the integrated clustering effects of all the criteria of each laser communication system were computed. Finally, the performance evaluation was done through determination of systems＇ clustering type. This method can convert a Multiple Criteria Decision Making （MCDM） problem into a Single Criterion Decision Making （SCDM） problem and it is a new method to evaluate laser communication system quantitatively.
