【摘要】：以复杂网络环境中的网络交易为研究背景,引入云模型理论,通过对复杂网络环境中的信任、信任影响因素及信任评价机制等问题的研究,提出了基于云模型的信任评估模型,实现了信任的定性与定量的转换,客观地反映了信任的随机性、模糊性和不可预测性;为了有效地对复杂网络中交易风险进行评估,研究并提出了基于云模型的风险评估方法。仿真实验表明,提出的信任评估模型能对复杂的网络环境中实体的信任做出合理的评价;基于云模型的风险评估方法能对电子商务中的交易风险进行合理可行的预测。设计并实现了一个基于云模型的风险评估系统,进一步验证了基于云模型的风险评估方法的可行性和合理性,也为复杂的网络环境中风险评估的研究提供了有价值的新思路。
[Abstract]:Taking the network transaction in the complex network environment as the research background, this paper introduces the cloud model theory, and puts forward the trust evaluation model based on the cloud model through the research of the trust, the factors influencing the trust and the trust evaluation mechanism in the complex network environment. It realizes the qualitative and quantitative transformation of trust, and objectively reflects the randomness, fuzziness and unpredictability of trust. In order to effectively evaluate the transaction risk in complex networks, a cloud model-based risk assessment method is proposed. Simulation results show that the proposed trust assessment model can evaluate the trust of entities in complex network environment reasonably, and the risk assessment method based on cloud model can predict the transaction risk in electronic commerce reasonably and feasible. A risk assessment system based on cloud model is designed and implemented, which further verifies the feasibility and rationality of the risk assessment method based on cloud model, and provides a valuable new idea for the research of risk assessment in complex network environment.
