  • Computing Warranty Costs

    This model illustrates how to use the Convolution element to compute cumulative warranty costs.

  • Moving Averages

    This model illustrates how an Integrator can be used to calculate moving averages.

  • Insert Time Step Overflow

    Compares reservoir outflow and overflow with and without the Advanced Simulation Setting to allow unscheduled updates selected.

  • Unscheduled Time Steps

    This model demonstrates how different Simulation Settings affect the plotted time history results for a simple pond overflow model.

  • Reservoir Reporting Periods

    The purpose of this model is to demonstrate the use of Reporting Periods in GoldSim.

  • Mono Lake Water Balance

    Water balance model illustrating a negative feedback loop and of the use of scenarios with a dashboard

  • Inventory Management

    A simple inventory management model that illustrates the structural differences between how such a model is constructed in GoldSim, and how it would be constructed using a classic System Dynamics code.

  • Predator-Prey Models

    This example implements several predator-prey models taken from "Modeling the Environment" by Andrew Ford.

  • Population Growth Aging Chain

    Example model illustrating population dynamics modeling with Discrete Change elements and Integrator arrays

  • Aging Chain

    Simulate an aging chain using various methods to keep track of the age structure of a stock of material or items.

  • Probability of Buying a Bike

    Tutorial model that calculates the probability that Jason can buy a bike given his income and spending

  • Competing Demands on a Reservoir

    This simple model shows one method for allocating competing demands on a Reservoir.

  • Controlling Reservoir Discharge

    This model explores 3 different methods of controlling discharge from a reservoir. The difference between these methods is important to understand for models that contain multiple reservoirs where discharge from one is being sent to another.

  • Dam Breach Hydrograph

    Simulate the breach in a dam as it grows through time and the resulting discharge hydrograph

  • Single Pool Reservoir

    Simulate the operation of a simple reservoir with an overflow spillway.

  • Simple Reservoir Operations

    This model illustrates how several methods for calculating a reservoir discharge can be combined into a single model. The methods includes calculations based on fluid physics, lookup tables and volumetrically under low-level conditions.

  • Simple Inventory Models

    This model file includes 5 variations on a simple inventory model. In each case, there is an initial inventory, a sinusoidal demand and a production rate that is constant, stochastic or influenced by feedback.
