The current Internet should not only support simple packet forwarding, but also be able to provide diverse network functions to compose different routing services on the communication paths for network applications. Meanwhile, the user requirements for different applications are becoming more and more diversified, it is a challenge to distinguish the differences among these requirements in order to...
In this work, we propose a two-dimensional model of opinion dynamics, in which two agents are neighbors if one of their opinion values is within a confident level. We present elementary consensus analysis that reveals the basic characteristics. The consensus threshold under uniform probability distribution is analyzed by means of numerical simulations. Comparison is made between the model and the...
In this paper, the opinion dynamics based on the 2-dimensional Krause-Hegselmann (KH) model is discussed. The opinion of each agent is represented by a vector with real-valued components between 0 and 1. Different consensus thresholds with two confidence level sets under the situation of uniform probability distribution are studied for the opinion dynamics analysis. Two scenarios are considered to...
Accurate forecast is the key for sales decision-making of tobacco commercial companies. Model selection plays an important role in sales forecast. This paper adopts expert system theory to model selection. Model knowledge tree is set up by selection rules to make knowledge structured and systematic. On the basic of model selection knowledge tree, build up model selection reasoning machine adopting...
