| 摘 要： | 在社会网络分析中，声望模型具有非常重要的地位，本文对目前普遍流行的声望模型进行了分析，不仅指出其本身存在理论缺陷，而且指出其普适性也不是很好。同时。本文利用最小成本原理，考虑了信息衰减、随机因素和多强度三方面因素，得到了新的声望模型，且对新声望模型和原声望模型就具体实例进行了比较，结论表明本文提出的模型决策意义明确、普适性好、可信性强。

| Abstract: | Prestige model is a very important one of social network.In the paper,the popular prestige model is studied.It shows that not only does the model commit fault in theory,but also it can't be used universally.According to the principle of Least Cost,the new prestige model is obtained from three aspects: the attenuation of information,random factors and multi-intensity.On the other hand,we have compared the new model with the old one by analyzing the same example,which shows that the new credible model has clear decision significance and can be used universally. |
