Introduction to Stella Architect




Stella Architect is a product of Isee Systems, a company that is dedicated to increasing understanding of our world through modeling and simulation software. Stella Architect is the latest version of Stella, which has been around since 1985 and has been used by thousands of educators, researchers, consultants, and policy makers around the world. Stella Architect is based on system dynamics, a method of modeling that focuses on the feedback loops and delays that shape the behavior of complex systems over time. Stella Architect also supports discrete event and agent-based modeling paradigms, allowing you to integrate different types of models into the same framework.

How to use Stella Architect for modeling and simulation?




To use Stella Architect for modeling and simulation, you need to follow three main steps:



  • Create a model using causal diagrams and equations.



  • Run a simulation using different settings and scenarios.



  • Analyze the results using graphs, tables, statistics, sensitivity analysis, etc.




Creating a model




To create a model using Stella Architect, follow these steps:



  • Create a new model file by clicking File > New or by pressing Ctrl+N (Windows) or Command+N (Mac).



  • Name your model file by clicking File > Save As or by pressing Ctrl+Shift+S (Windows) or Command+Shift+S (Mac).



  • Select a modeling paradigm (system dynamics, discrete event, agent-based) by clicking Model > Paradigm or by pressing F6.



  • Create a causal diagram by dragging icons from the palette onto the canvas. Connect them with arrows to represent causal relationships. Double-click on icons or arrows to edit their properties (name, equation, units).



  • Add text boxes or pictures to annotate your diagram by clicking Insert > Text Box or Insert > Picture. Resize or move them as needed.



  • Add submodels or modules to organize your model into hierarchical levels by clicking Model > New Submodel or Model > New Module. Drag icons from one level to another to link them together.




Running a simulation




To run a simulation using Stella Architect, follow these steps:



  • Select a simulation setting (time horizon, time step) by clicking Simulation > Settings or by pressing F7.



  • Select an initial condition (default values) by clicking Simulation > Initial Condition or by pressing F8.



  • Select a scenario (alternative values) by clicking Simulation > Scenario Manager or by pressing F9. Create new scenarios by clicking New Scenario button. Edit scenario values by double-clicking on cells in scenario table.



Analyzing the results




To analyze the results of your simulation using Stella Architect, follow these steps:



  • Select a graph or a table that displays the output variables you want to analyze.



  • Use the toolbar buttons to zoom in, zoom out, pan, or reset the view of the graph or table.



  • Use the legend to show or hide different variables or scenarios on the graph or table.



  • Use the context menu to change the graph or table properties, such as title, axis labels, colors, fonts, etc.



  • Use the statistics window to see summary statistics for each variable or scenario, such as mean, median, standard deviation, min, max, etc.



  • Use the sensitivity analysis window to see how sensitive each variable is to changes in input parameters.




How to publish and share your Stella Architect models?




To publish and share your Stella Architect models with others, follow these steps:


Publishing options




Stella Architect allows you to publish your models to different platforms and formats. You can choose from the following options:
