-
includes tools for assembling components and nesting assembled components
-
hide nested component details to
-
build complex systems
-
keep model uncluttered.
-
build complex systems

-
includes access to pseudo-random number generators such as
-
exponential
-
uniform
-
gamma
-
erlang
-
nonhomogeneous Poisson
-
user-built function of simulation state.
-
exponential
-
can use values in a SAS data set or view wherever pseudo-random numbers can be used to drive the simulation
-
displays sample data in charts such as
-
Strip Charts for displaying the age of transactions and saving simulation data in SAS data sets
-
Probes for sampling the state of Queues and Servers
-
Histograms and Box plots.
-
Strip Charts for displaying the age of transactions and saving simulation data in SAS data sets
-
animates the flow of transactions through the simulation network for presentation and model debugging (animation speed is
controllable)
-
analyzes sample data using statistical procedures in the SAS System
-
enables you to change model parameters interactively to
-
see the effects of changes
-
optimize the performance of the system.
-
see the effects of changes
-
enables you to selectively activate/deactivate components using the simulation controller with built-in time display
-
includes online documentation and help.
