SETTING SIMULATION PARAMETERS
A simulation contains six functional groups of parame-
ters. Parameters saved can be entered manually or read
in a fi le. These groups of parameters are as follows:
●
General: name of the simulation, units used through-
out the simulation, origin of the measurements, etc.
●
Scenario: description of the evolution of the measure-
ment conditions over time, including:
○
Simulation duration
○
Evolution over time of the physical quantities which
infl uence the measurements
○
Events which infl uence the measurements
●
Model: description of the detection assembly charac-
teristics including:
○
Detection effi ciencies of the radioisotopes
○
Sensitivity to the different nuclear backgrounds
○
Intrinsic and electronic noise
●
Algorithm: description of the algorithm parameters
(accessed from the MASS software)
●
Analysis: description of the statistical analyses to be
performed:
○
Defi nition of the confi dence rates to be evaluated
○
Defi nition of bias and standard deviation
●
Reports: description of the automatic reports to be
made during or at the end of the simulation:
○
Numerical and/or graphical printing
○
Data storage
SIMULATION BASED ON REAL MEASUREMENTS
It is possible to perform simulations in which the input
values provided to the algorithm are not simulated
values but are real measurements stored in ASCII fi les.
REPETITION OF IDENTICAL SIMULATIONS
The same event can be performed several times with
this SIMS functionality. This is especially advantageous
when evaluating response times. Indeed, if several iden-
tical simulations using different pseudo-random number
sequences are performed, reliable statistical information
can be obtained about the response times.
RUNNING A SEQUENCE OF SIMULATIONS
The SIMS software allows independent simulations to
be run sequentially and automatically using a “batch”
method.
