Discrete Event Multi-level Models for Systems Biology

Abstract: Abstract. Diverse modeling and simulation methods are being applied in the area of Systems Biology. Most models in Systems Biology can easily be located within the space that is spanned by three dimensions of modeling: continuous and discrete; quantitative and qualitative; stochastic and deterministic. These dimensions are not entirely independent nor are they exclusive. Many modeling approaches are hybrid as they combine continuous and discrete, quantitative and qualitative, stochastic and deterministic aspec… Show more

“…In our opinion, modelling such a kind of phenomena calls for: (i) representing the system's hierarchy, and the interaction among the hierarchical level using a multi-level model [22], [14]; and (ii) modelling the phenomena as close as possible to their known behaviour in the real world, so that we can adequately justify additional working hypotheses, and properly discuss simulation results giving them a meaning useful for biologists.…”

“…To reduce a model's complexity, the level of detail at which subsystems are described might be chosen differently, leading to multi-level modeling (Uhrmacher, Degenring, and Zeigler 2005). If part of the model is described as a deterministic, continuous model and other parts as stochastic, discrete event models, reliable hybrid methods for combining continuous with stochastic models become necessary.…”

“…in modeling the activities of the tryptophan operon in the cell as a multi-agent system, enzymes, DNA, and mRNA and repressors interact as autonomous reactive entities. Depending on the concentration of tryptophan and the state of the repressor, the repressor decides to move to the DNA and to block the operator inhibiting the production of mRNA and consequently of new enzymes [10]. Agents are used as a metaphor to describe and understand the dynamics within the cell.…”
