Random Variable Models Quiz

Sample space = Represents all possible outcomes for a random variable Stochastic model = Uses one or more random variables as inputs to the simulation System state = Collection of state variables needed to describe the system at a specific time Conceptual Model = Focuses on how comprehensive the model should be and identifies dynamic state variables

Deterministic Model = Simulation inputs consist of known values with no random variables Dynamic model = Represents a system as it evolves over time, like a conveyor system in a factory Discrete system = State variables change only at specific points in time, like in a bank example Continues system = State variables change continuously over time, as seen in the head of water behind a dam

Events = Instantaneous occurrences that can alter the system state without taking any time Mathematical model = Represents the system using logical and arithmetic relationships Simulation clock = Variable indicating the current simulated time value Validation = Ensures that the computational model aligns with the system being analyzed

<p>Balking = Customers decide not to join the queue Renege = Customers leave the queue after joining Jockeying = Customers switch between different queues Queue discipline = Determines order of service for customers</p> Signup and view all the answers

<p>Infinite-population models = Characterized by interarrival times of customers Scheduled arrivals = Customers arrive at specific times Random arrivals = Customers arrive at unpredictable times Interarrival times = Usually follow a probability distribution</p> Signup and view all the answers
