信用扩散与信用扩散场：一种MAS信用机制研究的新方法

为了研究复杂网络环境中MAS（Multi-Agent Systems）信用机制，本文引入信用扩散和信用扩散场的思想。为研究MAS的信用机制提供一种新的思路和方法。定义和分析了信用扩散系统，建立了信用扩散场数学模型，将影响信用扩散的主要因素加以抽象，建立了信用扩散场的三维空间坐标，为信用扩散构建了扩散的空间。并根据信用扩散场模型，提出了一种单源点信用梯度扩散算法。

Trust Diffusion Field:A Novel Solution of the Study of Trust Diffusion in MAS

To study the MAS trust mechanism in complex environment of network society, the concept of trust diffusion and trust diffuse field are introduced in the paper so as to provide a novel theory or method for the research of society trust mechanism of MAS. Having comprehensively surveyed the literatures relating to the theory of trust model of MAS, the paper gives the definition of trust diffusion system and analysis of it. The rust diffuse field theory is established. The main factors influencing trust diffusion are Abstracted to establish the 3D coordinate of trust diffusion field which sets the diffusion space for trust diffusion.On the basis of trust diffusion theory and trust diffuse field theory in MAS, it is created that a diffuse arithmetic of trust grads of single source peers.
