How does model stratification work?

Stratification allows you to compose models by crossing a base model (like an SIR disease model) with strata (like age groups or geographic locations) to create more granular, complex simulations.

What are Stock-and-Flow diagrams?

Stock-and-Flow diagrams are mathematical modeling tools consisting of stocks (accumulations like population), flows (rates of change), and links (influences) used to describe the behavior of dynamic systems over time.

Can I use this for COVID-19 or infectious disease modeling?

Yes, this skill is specifically designed to handle SIR, SEIR, and other stratified epidemiological models using mass-action semantics to generate the governing differential equations.

Does it support numerical simulation?

Yes, the skill generates ODEs that can be simulated using numerical solvers like DifferentialEquations.jl to analyze how a system evolves under different parameter sets.

Generates mass-action ODEs and dynamic simulations for epidemiological and ecological systems using stock-and-flow diagrams.

CatColab Stock-and-Flow Diagrams provide a rigorous mathematical framework for simulating complex systems defined by accumulations (stocks) and rates of change (flows). This skill allows users to build and analyze domain-specific models, such as SIR/SEIR epidemiological frameworks and Lotka-Volterra population dynamics, by automatically translating topological diagrams into mass-action Ordinary Differential Equations (ODEs). It supports advanced features like model stratification for age-based or spatial analysis and integrates directly with the AlgebraicJulia ecosystem for high-performance numerical simulation, making it an essential tool for researchers and engineers working on dynamic systems modeling.
