net.simplace.client.simulation.lap.generators.RandomSimGenerator

Generate simulations with parameters created randomly from specified distributions.

Distributions

For each parameter the user can chose one of the distributions

Distribution	Parameters	Return datatype	Remark
Uniform	min, max	DOUBLE
Normal	mean, sigma	DOUBLE
Exponential	lambda	DOUBLE
Poisson	lambda	INT
Binomial	n, p	INT

If min and max are specified and the generated value exceeds them, new random numbers are generated until one fits the interval. The number of trials is limited. If no number is found, the parameter set is skipped.

Generated parameter sets can be further restricted by constraints.

Variable specific configuration

Arbitrary number of calibration variables (either INT or DOUBLE, depending on distribution used)

<cal id="VariableName" ...

For each calibration variable the distribution and it's parametrization.

<cal id="VariableName1"
<input id="distribution" datatype="CHAR"
<input id="mean" datatype="DOUBLE" ...
<input id="sigma" datatype="DOUBLE" ...
<input id="lambda" datatype="DOUBLE" ...
<input id="p" datatype="DOUBLE" ...
<input id="n" datatype="INT" ...
</cal>
<cal id="VariableName2">
<input id="distribution" ...
<input id="mean" ...
...
</cal>

See the list above for possible Distributions and their required parameters.

General configuration

Name	DATATYPE	Description
cCount	INT	the number of parameter sets to be generated, mandatory
cRandomSeed	CHAR	optional random seed for the generator. Can be a long integer, therefore it has datatype CHAR

The number of created simulations can be smaller than Count.

the min and max attributes of the generated values may prohibit generation of some parameter sets
an additional constraint on the parameter set may prevent generation of a simulation

The random seed is set only on initialization of the generator. That means, that a subsequent iteration or a subsequent project can not set it's individual random seed.
