Beginner - Introductory Models

Fishery Simulation

A fishery simulation of stocks, flows, and feedback loops managing fish populations.

Level: Beginner

population resource-management sustainability management ecosystem stocks-flows reinforcing-loop balancing-loop renewable-resource quota-policy

Stocks: population
Flows: births, quota
Feedback Loops: reproduction (reinforcing), quota (balancing)
Probes: population, quota, gap_to_capacity, extracted_total

Run

Fork

Antifragile System

The same adaptive loop, two fates: with one knob negative each failure makes the system stronger; flip its sign and failures spiral to certain breakdown.

Level: Beginner

reinforcing-loop balancing-loop reliability antifragility

Stocks: failure_rate, total_failures
Flows: failure
Feedback Loops: antifragile healing (balancing), fragile spiral (reinforcing)
Probes: failure_rate, total_failures

Run

Fork

Goal-Seeking Decay

A goal-seeking decay simulation modeling exponential approach toward a target.

Level: Beginner

decay goal balancing-loop exponential control first-order-dynamics time-delay

Stocks: level
Flows: approach_rate
Feedback Loops: goal-seeking (balancing)
Probes: level, approach_rate

Run

Fork

Thermostat Simulation

A bang-bang thermostat reading a delayed sensor overshoots and rings; shorten the delay and it settles.

Level: Beginner

control time-delay balancing-loop

Stocks: indoor_temp
Flows: heat_gain, heat_loss
Feedback Loops: controller chasing set-point (balancing)
Probes: indoor_temp, error, heater_on

Run

Fork

Intermediate - Classic Dynamics

Dynamic Difficulty Adjustment

Adaptive encounters that track win rate to keep players challenged.

Level: Intermediate

gameplay reinforcing-loop balancing-loop adaptive game

Stocks: skill, difficulty, retention
Flows: practice gains, difficulty adaptation
Feedback Loops: skill improvement (reinforcing), challenge tuning (balancing)
Probes: skill, difficulty, win_rate, frustration, retention

Fork

Ride-Share Surge Control

Dynamic pricing stabilises rider waits—until high gain and delay turn it into surge whiplash.

Level: Intermediate

queue pricing elasticity balancing-loop delay oscillation

Stocks: Riders Waiting, Idle Drivers, Drivers on Trip
Flows: Passenger Arrivals, Driver Logins, Matches, Trip Completions, Driver Logouts
Feedback Loops: Wait-driven surge (balancing), High-gain with delay (reinforcing oscillation)
Probes: price_multiplier, wait_estimate, riders_waiting, idle_drivers, arrival_rate, driver_logins, matches_per_min

Run

Fork

SIR Model with Vaccination

An SIR epidemic at the threshold: vaccinating past the herd-immunity line pushes effective R0 below 1 and the outbreak fizzles.

Level: Intermediate

population reinforcing-loop balancing-loop control

Stocks: susceptible, infected, recovered
Flows: infections, recoveries
Feedback Loops: disease spread (reinforcing), susceptible depletion / herd immunity (balancing)
Probes: susceptible, infected, recovered, r_eff

Run

Fork

Sleep Debt Simulation

A sleep debt simulation tracking caffeine, sleep patterns, and debt buildup.

Level: Intermediate

debt reinforcing-loop balancing-loop

Stocks: sleep_debt_hours
Feedback Loops: coffee reduces sleep (reinforcing), circadian pressure triggers sleep (balancing)
Probes: sleep_debt, subjective_energy

Run

Fork

Water Heater PID Control

PID control keeps a domestic hot water tank near its setpoint while balancing heater power and losses.

Level: Intermediate

pid-control thermostat energy balancing-loop household control-systems temperature

Stocks: water_temperature
Flows: heater_input, heat_loss
Feedback Loops: PID control (balancing)
Probes: temperature, heater_output, error, setpoint
