Options on what, and what are you trying to explain. Generally there are 3 methods: Taylor Series (where you get exposed to non-linearities), overlay (where you explain 100% of the P&L but don't see the non- linearities known casually as bumped) and bump and reset where you reset each parameter.Have seen some stuff where Theta has been broken up into the gamma component and a time component. Also seen some royal stuffing up around dividend curves etc.If that is what you are looking for I have a high-level introductory paper somewhere that explains some of these concepts. PM me if you want a copy.
