System Dynamics readiness

Stocks-and-Flows Lab

A hands-on preparation for the System Dynamics sequence built on Sterman's Business Dynamics. Build and break the canonical models, from a simple bathtub to epidemics, supply chains, and collapse, until you read a stock-and-flow diagram as live mathematics.

OPEN THE LAB

Fourteen runnable models

Bathtub, goal-seeking, compounding, logistic, predator-prey, Bass diffusion, the beer game, the four-echelon supply chain, the SIR epidemic, overshoot-and-collapse, market growth, the workforce-inventory oscillator, the capability trap, and the shallow-lake tipping point, each with sliders, Euler and RK4 integration, a time-step guard, and a convergence test.
