M&S Exam Solved 100% Correct
System (Encyclopedia Americana) - Answer- An aggregation or assemblage of things
so combined as to form an integral or complex whole
System (IEEE Standard Dictionary) - Answer- A combination of components that act
together to perform a function not possible with any of the individual parts
In the study of systems, we are primarily concerned with: - Answer- - quantitative
analysis of systems
- techniques for system design, control, or use
- measurement or evaluation of system performance
A system that is the subject of a simulation study often is called the _____ - Answer-
Simuland
Model - Answer- A physical, mathematical, or otherwise logical
representation of a system, entity, phenomenon, or process
Simulation - Answer- A method for implementing a model over
time. Also, a technique for testing, analysis, or training in which real world systems are
used, or where a model reproduces real world and conceptual systems.
Modeling and Simulation - Answer- The process of using:
• Models
• Simulations
• Visualization
• Analysis
as a basis for making managerial or
technical decisions.
This includes, but is not limited to,
emulators, prototypes, simulations and
simulators.
Fidelity - Answer- A technical term that characterizes the accuracy of a simulation result
compared to the performance of the simuland
Resolution - Answer- A technical term that characterizes the
level of detail included in the model
representing a simuland
Scale - Answer- A technical term that characterizes the
size of a model representing a simuland or
simulation scenario
, Verification - Answer- Process of demonstrating that the simulation code accurately
represents the developer's conceptual description and specification for the system
model
Validation - Answer- Process of demonstrating the degree to which a model and
simulation represents the simuland
Static System - Answer- A system in which the output depends only on the input and is
independent of the system state
Dynamic System - Answer- A system in which the output depends on both the input and
the system state
State of a System - Answer- The information required at t such that the output y(t), for
all t>t0, is uniquely determined from this information and from the input x(t) for t>t0.
State Variables - Answer- State information usually represented components in a vector
q(t)
State Space - Answer- The set of all possible values that q(t) may take (denoted by Q)
Continuous-State System - Answer- A system in which the state space Q consists of
vectors which can assume a continuum of values. We say that q(t) ε R (reals).
Discrete-State System - Answer- A system in which the state space Q consists of
vectors which can assume only a discrete set of values. We say that q(t) ε I (integers).
As a consequence, state changes occur at distinct time instants.
Event - Answer- A specific instantaneous action or occurrence which results in an
instantaneous change of system state
Event-Driven Systems - Answer- With each discrete-state transition, we associate an
event. Further, we attribute the state transition to the occurrence of the event
Time-Driven Systems - Answer- The system response varies as a continuous function
of time, even when there is no change in the system input. Thus, the system state
appears to evolve simply because time advances
Deterministic System - Answer- A system in which all variables are deterministic
Stochastic System - Answer- A system in which one or more variables has uncertainty
or variability. In this case, the system state becomes a random variable and a
probabilistic framework is required to describe system behavior.
Continuous-Time System - Answer- A system in which the time variable is represented
by a continuous variable; t ε R
