GPSS
- General Purpose Simulation System (GPSS):
- one of the oldest existing modeling languages
- uses the transaction-based paradigm
- text-based
- GPSS elements:
- generation and destruction of entities
- entering and leaving of queues
- reservation and freeing of servers
- delaying of an entity for a given (service) time
- GPSS user chain:
- flexible queue element in GPSS
- entities enter with link at
front or back end
- entities can be extracted with unlink
and routed arbitrarily
- possibilities of unlink depend on GPSS implementation
- MatlabGPSS:
- Matlab-based GPSS implementation
- freely available
- combines GPSS statements with general Matlab code
- Matlab for control structure, statistical and
graphical results
- unlink only for first or
last entity
