Singleserver - a fundamental example

• Basic model:
  • 
  • Generator creates entities with tG = 1
  • Queue with unlimited capacity, outputs current queue length nq
  • Server with tS = 1.5, outputs no. of stored entities (0/1) and blocking status
  • Terminator
• Implementation of Queue:
  • 
• Behaviour of the model:
  • push strategy = entities proceed as far as possible
  • complex cascades of concurrent events, e.g. when server gets ready and queue holds several entities
