Dear Abdolali,
My understanding of sensitivity tests are that they test the sensitivity of the "model" to certain input variables.  In the sensitivity analysis you are testing to see if the model is realistic enough for subsequent use.

Scenario analyses evaluate the likely consequences of particular "real world" management options given certain scenarios (e.g. changing weather patterns or management options etc...).  You use the model to help answer the real world questions, assuming that the model is realistic.

So these two types of analyses used in modelling are quite different in objective.  Does this help?

Kind regards,
Garry O'Leary
