Simulation method

Precautions, Comparisons and Steps for simulation use (I’ll share again some quotes from same book)

Simulation’s effectiveness is based largely on the modeler’s ability to identify cause and effect relationship in system and conduct appropriate experiment

PRECAUTIONS IN USING SIMULATION:

  • Can be expensive and time consuming to initially get started.
  • Sometimes easier and better solutions get overlooked.
  • Results can be misinterpreted.
  • Human and technological factors may get ignored.
  • May place too much confidence in simulation results
  • It’s difficult to verify whether the results are valid.

STEPS FOR GETTING STARTED SIMULATION

0: Management basic understanding and recognizing basic needs to business

1: Appoint a simulation champion

2: Determine Simulation needs

3: Asses current SIM techs (search and ask to recent users)

4: Evaluate and select SIM software

5: Acquire any additional hardware

6: Conduct pilot project

 

DETERMINE SIM NEEDS

  • Frequency of use: How often will SIM be used
  • Types of Application: Diverse or “what if” analysis
  • Charactheristic of system to be modeled
  • Users
  • Whom the simulation being used
