Golden Rules of Simulation
Golden Rule 9
M/S VV&T activities should be considered as
confidence building activities.
Golden Rule 1
Model and/or Simulation (M/S) VV&T should be conducted hand in hand as integrated within the entire M&S application development life cycle.
Golden Rule 3
An M/S is built for a prescribed set of intended uses and its accuracy is judged with respect to those intended uses.
Golden Rule 4
M/S VV&T requires independence to prevent developer’s bias.
Financial Independence implies that the M/S VV&T agent is allocated its own budget and does not rely on M&S application development budget.
Golden Rule 8
Complete testing is not possible for large and
complex models and/or simulations.
Golden Rule 10
M/S VV&T activities should be planned and documented throughout the entire M&S development life cycle.
Golden Rule 2
M/S VV&T outcome should not be considered as
a binary variable where M/S accuracy is either perfect or totally imperfect.
Golden Rule 5
M/S VV&T is difficult and requires creativity
and insight.
Golden Rule 6
M/S VV&T is situation dependent.
VV&T is applied depending on the particular accuracy assessment task, M/S type, M/S size, M/S complexity, and the nature of the artifact subjected to VV&T.
Golden Rule 16
Certification should be conducted by an
independent third party.
Golden Rule 19
M&S application sponsor should clearly dictate the rules of conduct between the M&S application developer and M&S application certification agent.
Golden Rule 11
Errors should be detected as early as possible in the M&S application development life cycle.
Golden Rule 13
Successfully testing each submodel (module) does not imply overall model validity.
Golden Rule 18
A certification agent should be accredited.
Golden Rule 14
Formulated problem accuracy greatly affects the acceptability and credibility of M&S results.
Golden Rule 12
Double validation problem should be recognized
and resolved properly.
Golden Rule 20
Certification outcome should be presented with
a level of confidence.
Golden Rule 17
Certification should be conducted concurrently throughout the entire development life cycle of a new M&S application.
Golden Rule 15
Type I, II and III errors should be recognized and prevented. Three types of errors may be committed in developing an M&S application:
• Type I Error is committed when the M&S application results are rejected when in fact they are sufficiently credible.
• Type II Error is committed when the M&S application results are accepted when in fact they are not sufficiently credible.
• Type III Error occurs when the wrong problem is solved and is committed when the formulated problem does not completely contain the actual problem.
Verification, Validation, and Testing (VV&T).
Modeling and simulation (M&S)
Golden Rule 7
M/S accuracy can be claimed only for the intended uses for which the M/S is tested.
