Purpose or Uses of a Model:
  • Helps decision maker in better understanding of mnemonic operations
  • Helpful prior to to induction of new weapon systems
  • Evolving a new tactics
  • Planning the development of new costly weapon systems
  • Used in Analysis (R&E tools, Operation Support tools), Training & Education(Skill development, Exercise Drivers)

Effective Model:
  • Realistic Modeling--->Complex Models--->High Costs
  • Therefore, appropriate abstractions required to reduce the cost. Balance between the cost of model and actual system is essential to make the model effective
Model is NOT:
  • a substitute for hard thinking
  • a decision maker itself
  • address unasked questions
