and create virtual representations of real-world processes, enabling risk-free experimentation for optimization. These tools support decision-making through scenario analysis, allowing businesses to test ideas and predict performance without real-world consequences.
Model development follows a structured process, from problem definition to validation. Various software tools aid in creating simulations, with components like entities, activities, and resources mimicking real-world processes. and result interpretation help businesses optimize operations and guide improvements.

Simulation and modeling create virtual representations of real-world processes enabling computer-based experimentation
Process optimization benefits from risk-free experimentation allowing cost-effective analysis and time compression
Decision-making support through scenario analysis enables what-if testing and performance prediction
Types of simulation models include mimics sequential events, simulates individual behaviors, models complex feedback systems
Development of simulation models
Model development follows steps: 1) Define problem 2) Collect data 3) Conceptualize model 4) Translate model 5) Verify 6) Validate
Software tools for simulation include specializes in discrete event, AnyLogic supports multiple paradigms, Simul8 focuses on business processes, ExtendSim offers customizable blocks
Model components comprise entities (items processed), activities (tasks performed), resources (personnel or equipment), queues (waiting lines)
Validation techniques ensure model accuracy through face validity (expert review), historical data validation (comparing to past data), sensitivity analysis (testing input variations), extreme condition tests (checking model behavior in edge cases)
Sensitivity analysis with simulations
Sensitivity analysis varies input parameters to observe output changes assessing model robustness
evaluates process performance under best-case optimistic projections, worst-case pessimistic outlooks, most likely realistic estimates
