Simulation - Group 2
1.2 When is simulation not appropriate?
(Andy)
1st Rule
: When the problem can be solve using common sense
2nd Rule
: When the problem can be solved analytically
3rd Rule
: When the problem is easier to solve by performing direct experiments
4th Rule:
When the cost exceed the savings
5th Rule:
When the resources are not available
6th Rule:
When there is no / not enough time being allocated
7th Rule:
When there is no ability to verify and validate the model
8th Rule:
When managers haver unreasonable expectations
9th Rule:
When system behavior is too complex or cannot be defined
1.1 When is Simulation the appropriate tool?
(Yee tong)
When informational, organizational and environmental changes are required to be simulated
Effects of the model's behavior can be studied
When designing simulation model will bring
value add
to improve system that is under investigation
When a study or a realization of a
internal interactions
of a
complex
system or its subsystem are required
When observing and changing simulation values will obtain variables which are important and how the
variables interact
When the simulation can be used as a
pedagogical device
to reinforce analytic solution methodologies
When the simulation can experiment with new
designs
or
policies
prior to the implementation, to be
future proof
When simulation can be used to verify
analytic
solution
When by simulation
different capabilities
for a machine, its
requirements
can be determined
When the simulation model can be used for training purposes with the
cost
and
disruption
of on-the-job learning

Military
"Virtual simulations inject human-in-the-loop in a central role by exercising motor control skills (e.g., flying an airplane), decision skills (e.g., committing fire control resources to action), or communication skills (e.g, as members of a C4I team) From (

1.3 Pros and Cons
(Kai Ler)
Advantages
Allows exploration of the implementation of new procedures and operations
without disrupting existing operation
Interaction of variables can be observed
with respect to system performance
Allows for observation of
long-term effects
Provides an accurate
systems-wide overview
of operations
Allows rigorous testing of '
what-if
' scenarios
Disadvantages
Simulations output raw results, and thus have data that
could be difficult to interpret
Simulation modelling is
time-consuming and expensive to set up
Model-building has a
high barrier to entry.
There might be
better methods to simulate some aspects
of industrial systems
