Using Qualitative Technology for Modeling the Process of Virus Infection

摘要

The quantitative analysis of viral infection dynamical model can't be processed easily due to the lack of complex quantitative knowledge in such biological system; therefore, the methods based on qualitative analysis become an alternative solution to researches in the complicated biological process. In this paper the qualitative technology is introduced to model and analyze the process of virus entry. A rough model is proposed first to be the foundation of further research. With more knowledge in the process, the framework is expanded by inserting the qualitative description of different kinds of factors that have interactive influence on the process of virus entry. The factors are described qualitatively in influencing degree, and the qualitative model is built based on the interaction among these influencing factors and the viruses and cells. The judging matrices are constructed according to the qualitative model and the coherence of these matrices is verified. A qualitative analysis about the process is given finally.
