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

Player model to illustrate differences in dashboards and scenarios between Player and GoldSim

Example model illustrating feedback from pressure and fatigue on productivity and quality

This simple model simulates the classic Polya urn problem in which stones, either black or white, are randomly selected (with replacement and addition) from a pot.

This is a model of the population dynamics of three groups adopting dove, hawk and lawabider strategies.

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.

This model illustrates perhaps the most famous example of chaotic behavior: that exhibited by the ´logistic difference´ equation to describe the growth of a population subject to a carrying capacity.

This example implements several predatorprey models taken from "Modeling the Environment" by Andrew Ford.

This is a simple model that simulates the life cycle of a salmon population as it migrates from the stream, to the ocean, and back to the stream. Although the data and model structure are fictional, it does provide a simple example of how such a model could be constructed.

These two models (continuous and discrete) simulate the spread of an acute infection through a population

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

A logistic growth curve model is employed to simulate the adoption and diffusion of a new idea or technology

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.

This is a demonstration model of an automobile supply chain. It represents two links in the chain: the OEM and a major tier 1 supplier (in this case, power trains).
