Modeling knowledge networks

Abstract

The goal of this thesis is to construct and explore new mathematical models of knowledge diffusion in organizational communication networks. The conventional diffusion equation is limited to random “agent-to-agent” interactions. However in practice, humans are more than “mindless” molecules. Human “agent-to-agent” interactions involve, in addition to diffusion, rational decisions-selections limited by the inherent uncertainty (bounded rationality). Taking into consideration this key observation, we constructed new mathematical models for knowledge diffusion within networks, which incorporate the awareness of the selecting-communicating agents. This is precisely the originality of the thesis. Based on the newly constructed modeling framework, we simulated and compared several different communication policies among the agents of the network for knowledge acquisition. There are three research issues addressed in this thesis, namely: (1) the impact of false beliefs and unreliable communica ...
