stella模擬軟體單機版

Use STELLA to:

• Simulate a system over time
• Jump the gap between theory and the real world
• Enable students to creatively change systems
• Teach students to look for relationships – see the Big Picture
• Clearly communicate system inputs and outputs and demonstrate outcomes

Key Features

Mapping and Modeling

• Intuitive icon-based graphical interface simplifies model building • Stock and Flow diagrams support the common language of Systems Thinking and provide insight into how systems work • Enhanced stock types enable discrete and continuous processes with support for queues, ovens, and enhanced conveyors • Causal Loop Diagrams present overall causal relationships • Model equations are automatically generated and made accessible beneath the model layer • Built-in functions facilitate mathematical, statistical, and logical operations • Multi-dimensional arrays simply represent repeated model structure • Modules support multi-level, hierarchical model structures that can serve as “building blocks” for model construction • XML-based model files support the new industry standard for common interchange of system dynamics models

Simulation and Analysis

• Simulations "run" systems over time • Sensitivity analysis reveals key leverage points and optimal conditions • Partial model simulations focus analysis on specific sectors or modules of the model • Results presented as graphs, tables, animations, QuickTime movies, and files • Data Manager archives and recalls simulation run data stored in a separate SQLite database file • Dynamic data import/export links to Microsoft® Excel or CSV files

Communication

• Flight simulators and dashboards describe model components and facilitate manipulation Click to Enlarge Screenshot  Dashboards bridge the gap  between theory and reality. • Input devices include knobs, sliders, switches, and buttons • Output devices highlight outcomes with warning flashers, text, graphs, tables, and reports • Storytelling supports step-by-step model unveiling • Causal Loop Diagrams present dominant feedback loops within structure • Export for NetSim supports publishing and sharing model over the web using isee NetSim add-on software • isee Runtime options support full-screen presentation of models so they can be easily shared or commercially distributed • Multimedia support for graphics, movies, sounds, and text messages • Model security features allow locking or password protection
