INTRODUCTION TO SIMULATION
WHEN SIMULATION IS AN APPROPRIATE TOOL
The
STUDY AND EXPERIMENTATION
with the internal interactions of a complex or subsystem within a complex system
Informational, organisational, environmental changes simulated to
OBSERVE
the effects of alterations on the model's behaviour
Knowledge gained to
RECOMMEND IMPROVEMENTS
on the system under investigation
To
IDENTIFY
the
MOST IMPORTANT VARIABLES
and
HOW VARIABLES INTERACT
by changing simulation inputs and observing the outputs
Can be used as a pedagogical device to
REINFORCE
analytic solution methodologies
To
EXPERIMENT
with new designs or policies before implementation to
PREPARE FOR WHAT MIGHT HAPPEN
To
VERIFY
analytic solutions
DETERMINE MACHINE'S REQUIREMENTS
by simulating different capabilities
Enables
CHEAPER
and
LESS DISRUPTIVE TRAINING
Able to show system in simulated operation to
VISUALISE PLANS
TREAT
the internal interaction of a modern complex system
ADVANTAGES OF SIMULATION
NEW PROTOCOL
can be explored without disrupting current system operations.
NEW INFRASTRUCTURE
can be tested without committing resources for their acquisition.
HYPOTHESIS
about how or why certain phenomena occur can be tested for
FEASIBILITY
.
The manipulation of time allows for either
ACCELERATION or DECCELERATION
of the phenomena being studied.
INSIGHTS
can be obtained about the
INTERACTION OF VARIABLES
.
INSIGHTS
can be obtained about the
IMPORTANCE OF VARIABLES
to the performance of the system.
BOTTLENECK ANALYSIS
helps identify areas that are
EXPERIENCE EXCESSIVE DELAYS
.
Simulation studies reveal how a system
TRULY OPERATES
, distinct from individual perspectives on its functioning.
"WHAT IF" QUESTIONS
can be answered.

Additional Application
WHEN SIMULATION IS
NOT
AN APPROPRIATE TOOL
RESOURCES
are
UNAVAILABLE
TIME
is
UNAVAILABLE
Simulation
COST EXCEEDS SAVINGS
NO DATA
or
ESTIMATES ARE UNAVAILABLE
It is
LESS EXPENSIVE
to perform
DIRECT EXPERIMENTS
Model is
UNABLE TO BE VERIFIED AND VALIDATED
Problem can be solved
ANALYTICALLY
INSUFFICIENT TIME
and
LACK OF AVAILABLE PERSONNEL
Problem can be solved by
COMMON SENSE
System behaviour is
TOO COMPLEX
and
CANNOT BE DEFINED
DISADVANTAGES OF SIMULATION
Simulation modelling and analysis can be
TIME CONSUMING AND EXPENSIVE
OFFSET:
ADVANCEMENTS IN HARDWARE AND SIMULATION PACKAGES
permits the rapid running of scenarios
Used in cases where
ANALYTICAL SOLUTIONS
were
POSSIBLE or PREFERABLE
OFFSET:
CLOSED-FORM SYSTEMS
(
any formula that can be evaluated in a finite number of standard operations
) are not able to analyse most complex systems
Simulation results can be
DIFFICULT TO INTERPRET
OFFSET:
Development of
OUTPUT-ANALYSIS CAPABILITIES
which can perform very thorough analyses
Model Building requires
SPECIAL TRAINING
OFFSET:
Development of models that
ONLY REQUIRE DATA INPUT
