Systems simulation Flashcards
(30 cards)
What is a model?
A simplified representation of reality used to understand, predict, and control systems or phenomena.
What are the types of models?
- Mathematical Models
- Physical Models
- Computational Models
What do mathematical models use to represent systems?
Equations and formulas.
What are physical models?
Tangible representations, such as scale models of buildings or wind tunnel models for aerodynamics.
What are computational models?
Simulations and algorithms to represent systems, such as weather forecasting or population dynamics.
What happens when coefficients in a quadratic equation change?
It affects the graph’s shape and position.
What is the importance of physical models in engineering?
They help engineers test real-world behavior without full-scale prototypes.
What does the wolf-sheep predation simulation demonstrate?
How predator and prey populations fluctuate in cycles.
What does S(t) represent in the wolf-sheep interaction model?
Sheep population at time t.
What does W(t) represent in the wolf-sheep interaction model?
Wolf population at time t.
What is the role of the sheep growth rate (rS) in the model?
It indicates how fast the sheep population increases.
True or False: More wolves lead to an increase in the sheep population.
False.
What is a simulation?
A virtual experiment that mimics real-world processes using computers.
What is the purpose of simulation?
Saves time and resources by avoiding physical testing.
What is time-stepping in simulations?
Dividing a process into small time intervals.
What is discrete event simulation (DES)?
Models a system as a sequence of discrete events.
What is Monte Carlo simulation used for?
Estimating outcomes in uncertain situations.
What does agent-based simulation model?
Interactions between autonomous agents.
What is continuous simulation?
Models systems with continuous change, often using differential equations.
What is hybrid simulation?
Combines discrete and continuous simulation methods.
What is system dynamics simulation focused on?
Long-term behavior using feedback loops and time delays.
What is virtual reality simulation (VR)?
Immersive environments for training, gaming, and therapy.
What is simulation software?
Programs that help create and run simulations for analyzing complex systems.
What is MATLAB used for?
Numerical computing and visualization.
