Introduction
- Discrete systems
- many different modeling paradigms
- graphical methods
- abstract (Petri nets, state graphs)
- medium level of abstraction (entities
running through components)
- concrete (material flow applications, e.g.
PlantSimulation)
- medium level widely used
- sufficiently abstract to be universally
applicable
- concrete enough to be comprehensible by users
- process based (active components, e.g. Arena) or
transaction based (active entities, e.g. SimEvents)
- Closer look at transaction based modeling
- no well-established set of basic features and
components (cf. SimEvents 4.4 → 5.0)
- open issues
- shortcomings of current implementations
- missing concepts or components
- reasonable set of components
- strategy
- implement many different applications
- concrete: SimEvents 4.4 (Mathworks)
