Machinations vs Arena Simulation
Machinations gives a team one shared diagram of how resources, incentives and feedback interact across an economy, ready to Play and discuss with collaborators.
Machinations and Arena Simulation at a glance
Arena Simulation and Machinations make different modeling choices. Arena is oriented around process flow and discrete-event operations; Machinations provides a visual language for connected resources, rules and feedback.

Who should choose which
Where Machinations may fit
Consider Machinations when the central question is how resources, incentives and feedback interact across an economy or complex system, and collaborators need to inspect and Play the model. Monte Carlo Forecasts, which Play a model many times to show the range of possible outcomes, run on Machinations’ cloud servers.
Where Arena Simulation may fit
Consider Arena when the problem is a process with ordered events, constrained resources, variability, throughput or cycle-time measures, and you need to explore operational scenarios.
How to decide
A process-flow model and a resource-flow model can describe different aspects of the same real system. Choose the approach that makes the decision variables and relationships in your question easiest to validate. In the table above, Cloud execution for Machinations means that its Monte Carlo Forecasts run on its cloud servers.
