Dear Sir/Mam,
I am a new user of System Dyanmics and now a
days trying to make a model relaed to energies
like Oil, Gas, Coal and Electricity. My purpose is
to find "enerrgy demand forecast" and to find
"energy gab" with the help of supplies.
I already made a model and want some expert
to have a look and make changes as required.
So please see attachment for my model.
I really appreciate your self in advance.
Please answer me at "gparas111@yahoo.com". I am
waiting for the feedback.
Thanks
John.

Hi John,
Just have had a look on your model and would have the following advices:
1. Draw the reference modes for the variables in the model (the past behavior and the wished/feared)
2. Re-(Down-)size the model to the most essential feedbacks!
3. Start all over again (building up the model slowly) - indicating the causal relation (+) and (-) on each cause-effect
4. Involve other people in the early on discussion (friends, fellow workers, etc.), in order to find out the assumptions that have driven the behavior patterns in the past.
This may be not what you were looking for in the beginning, it will be worthwhile and the achievements and insights you will gain will be beneficiary.
Best regards
Ralf
