摘　　要：目的解决卫星伸展机构参数表现形式多样且不确定的问题。方法运用图示评审技术,构建MU-GERT网络模型,并将参数统一用广义灰数表征。考虑解析算法的复杂性,提出针对该网络模型的矩阵式表征方法,并设计出矩阵式求解算法,便于运用计算机编程进行准确快速的求解。结果用MU-GERT网络模型计算概率不确定时制作一个合格卫星伸展机构需要的时间,仿真模拟出制作出一个合格卫星伸展机构的期望与机会。结论为图示评审技术在卫星伸展机构研制中的应用提供了研究思路和经验借鉴。Objective To solve the varied and uncertain parameters of satellite extension mechanism.Methods The MU-GERT network model was constructed by the graphical review technique,whose parameters were represented by generalized Grey number.Considering the complexity of analysis algorithm in random network,this paper proposed a matrix determinant solution of MU-GERT network model.The algorithm was designed to solve the problem quickly and accurately by computer.Results The MU-GERT network model was used to calculate the time of making a qualified sat-ellite extension mechanism when the probability was uncertain,to simulate the expectations and opportunities for pro-ducing a qualified satellite extension mechanism when the time was uncertain.Conclusion It provides references for the application of graphical evaluation review technique on the development of satellite extension mechanism.
