Elements Of Simulation -
are the components that provide service to entities. Because resources are usually limited, they create constraints . The interaction between entities demanding service and the limited capacity of resources is what typically creates bottlenecks, making this element essential for problem-solving. 6. Stochastic (Random) Components
These are the "knobs" the researcher turns to see how the system reacts (e.g., adding a second cashier). 4. Events and Logic Elements of Simulation
The first step in any simulation is defining the —the specific part of the real world being studied. Establishing boundaries is critical; you must decide what is internal to the model and what external factors (the environment) will influence it. For example, in a flight simulator, the aircraft is the system, while wind and air pressure are environmental inputs. 2. Entities and Attributes are the components that provide service to entities
These track the status of the system (e.g., the number of people in a queue). Events and Logic The first step in any
Simulations are driven by , which are occurrences that change the state of the system. In a "Discrete Event Simulation," the clock jumps from one event to the next (e.g., a customer arriving or leaving). The logic or rules of the simulation dictate exactly what happens when an event occurs, ensuring the model follows "real-world" physics or operational procedures. 5. Resources and Constraints
The of a simulation is a snapshot of the system at any given moment. This is defined by variables .
Simulation is a powerful technique used across science, engineering, and social studies to recreate the behavior of a real-world system over time. To be effective, a simulation must move beyond simple animation and incorporate specific structural components. Here are the core elements that define a simulation: 1. The System and its Boundaries
