The quantify and dynamic evolution of trust among supply chain

Using system dynamics methods, this article grasps firmly the information bond of trust, considers the interaction among information, trust, logistics, capital flow, profits flow, study the quantify and dynamic evolution of trust among supply chain and carries out a simulation. The results show that: if the amount of information is great, the trust track point will appears in advance and trust will always be high. If information quality is good, the trust track point occurs early, but with the cycle progresses, the trust will tend to be the same level.
