Simulation

Simulation

1. System dynamic

   • Human based systems
     • Feedbacks
       • Positive
         • Adds variance to output
       • Negative
         • Reduce variance between actual output and target output.
     • Delays
   • Generic structure
     • Underlying causes behind behavior
   • Organisational learning
   • Identify system elements that produce dynamic behavior
     • Stocks
       • Accumulation of resources
     • Flows
       • Movement of resources
         • Falling, rising and maintaining stock
   • Transformation of resources
     • Sequence of linked levels

2. Discrete-event

   • Replicate the structure of the system (known structure)
     • Collect data
       • Process flows
       • Process times
       • Demand patterns
   • Discover how it behaves under different conditions
     • Prediction of a real system under different scenarios
   • Series of events
     • System performance and animation capabilities
       • VIS (Visual interacting simulation)
     • Attributes
