comment What is the reasoning to derive this financial model called the Vasicek Model?
The equation at the start of your question is not a model preposition. It's just a model, it has some useful properties but doesn't follow from the usual axioms. It's not the truth. Why we want to use it is in the Discussion section there and in the papers linked in at the bottom of the Wiki-page.

comment Why we substitute volatility into other financial models?
Well that follows from the definition. For estimating the volatility different approaches exist, e.g. quant.stackexchange.com/q/11306/848. However, that's not what you asked, if your interested in estimating please rephrase your question. For now I will put it on hold as too basic since the formula follows (under the appropriate assumptions) from the definitions).

Well to model interest rates... Do you mean: why model them like that?

Hi Ginger, welcome to quant.SE! I've removed your 'disclaimer' and cleared up the title. However, I believe one thing is missing: what model are you using?

comment multiperiod optimization using R
I don't believe there is any universal package or approach for multi-period optimizing (but I'd love to be wrong). Can you be more specific what kind of problems you're trying to solve?
