Introduction to Modeling & Simulation Lecture 1 (Simplified Version)
Learning Goals Samajhna: System, Model, Simulation Simulation ki need kyu hai? Types of systems aur models
What is a System? Components jo ek sath kaam karte hain Input → Process → Output → Feedback Examples: Traffic system, Hospital, Banking system
Why Study Systems? Complex real-world problems ko simplify karne ke liye System analysis helps to: Identify objectives Boundaries define karna Components aur environment samajhna
What is a Model? Simplified version of a system Sirf important details ko represent karta hai Examples: Map, Equation, Flight Simulator
What is Simulation? Model ko chalana jisse system ki real behavior imitate ho Examples: Weather forecast, Traffic simulation, Flight training
Why Simulation? Real system pe test karna mushkil, costly, ya dangerous ho sakta hai Simulation is: Safe Cost-effective Repeatable
Classification of Systems Natural vs. Man-made Deterministic vs. Stochastic Static vs. Dynamic Continuous vs. Discrete Open vs. Closed
Examples of System Types Traffic lights → Discrete, Dynamic Weather → Continuous, Stochastic Solar system → Deterministic, Continuous
Advantages of Simulation Cost-saving Risk-free Time-saving Experiment repeatability
Limitations of Simulation Approximation hoti hai (100% accurate nahi) Valid data required Kabhi kabhi expensive bhi ho sakti hai
Applications of Simulation Engineering (aircraft, cars) Medical (disease spread, surgery training) Business (bank queues, supply chain) Computer Science (networks, AI)
Summary System = interconnected components Model = simplified version Simulation = model execution Simulation is useful, but not perfect
Review Questions System aur model me difference kya hai? Ek deterministic aur ek stochastic system ka example do. Simulation ki ek real-life application likho.
