Simulation and Modelling

Notes 8. In discrete-event simulations, as opposed to real time simulations, time 'hops' because
events are ......................

10. ...................... could conceivably be carried out by hand it can be computationally intensive,
therefore will invariably involve computers and software.
11. Results & Statistics are important in ...................... the model and for providing performance
measures.

12. Simulation approaches are particularly well equipped to help users ...................... issues in
complex environments.
13. A working model of a system allows management to understand ...................... drivers.

14. Many small orders may cause ...................... due to excess changeovers.
15. ...................... takes this concept one stage further by allowing the model to be created
interactively.

4.6 Review Questions

1. What is Discrete System Simulation? Examine the various components of discrete event
simulation.
2. What do you think are the common uses of discrete event simulation?

3. What is Visualization? Explain how does it enables the status of the model to be viewed as
it progresses.
4. Make distinctions between traditional program development and Object Oriented
techniques.
5. Scrutinize the implementation of Plasmodium Falciparum Malaria in discrete event
simulation.
6. Analyze the distinctive points between Fixed Time Step vs. Event-to-Event Model.
7. The simulation must keep track of the current simulation time. Elaborate.
8. Do you think the simulation maintains at least one list of simulation events?

9. Single-threaded simulation engines based on instantaneous events have just one current
event. Comment.
10. Explain the key features found in the software simulation model.
