3 important questions on Simulation Software - Classification of Simulation Software

General purpose vs application oriented simulation packages

General-purpose simulation packages:
- can be used fro any application
- may have special features for certain applications

Application oriented simulation packages
- Designed to be used for a certain class of applications
Exists for: e.g: manufacturing, communications, supply chains etc

What's a process in the process approach

Time-ordered sequence of interrelated events separated by intervals of time, which describes the entire experience of an "entity" as if flows through a "system"

Disadvantages Process-interaction approach

∗ Parallel activities (like queueing and reneging)
- entities in queue are passive
- Requires complex hold on condition
- reneging is arranged by dummy entities who remove originalentities from
queue when deadline elapses
* Queueing and jockeying:
- if entity is in a queue we cannot keep track of it so we need a dummy variable

The question on the page originate from the summary of the following study material:

  • A unique study and practice tool
  • Never study anything twice again
  • Get the grades you hope for
  • 100% sure, 100% understanding
Remember faster, study better. Scientifically proven.
