can you specify what your model is?

ANNs are universal approximators, so with the right network, yes, you can model your problem.

i think Attach file will give better idea.

YES U CAN MODEL UR PROBLEM 

@Luma Alsamia..How?Can you define few lines?

I think if u want to use ANN for modeling NL transfer function u need ANN network with feed back, the structure will be as perceptron  with bias but it must be worked with feedback as Back propagation network, there is a learning stage and error calculation and there must be weights ,,,, BP network is better for this modeling
