Cybernetic Modelling. Proof-of-Concept Example

Abstract

Continuing the preceding paper [5], this one illustrates Cybernetic Modelling, applying it to biologic stability. A Lotka-Volterra model for predator-prey species is employed to (discrete-time) modelling homeostasis with hysteretic delay, simulating (macrochronic) stability of simple cybernetic (Barkhausen loop) systems. NL-capability is achieved replacing differential equations by iterative loops (with polysemantic time granularity) and employing (some) non-numeric mathematics. The modelling subspecies is evaluated from both transdisciplinary bridge legs: software engineering (undemanding yet flexible post-industrial apparatus) and biology/ecology (versatile (field or laboratory) research tool, with user-friendly interface, allowing to write “What-if” scenarios for handling (over)simplified ecologic (sub)systems in their real-world habitats).
