Question on organic chemistry side-chain's naming rules

What are the rule(s) for naming an organic chemical compound that has more than one side-chains, such as ketone and a C-C triple bond ('yne')? 

Another words, which is the "ranking" of the importance of the side-chain which determines the naming of that entire molecule? 

I know that the alkyl/alkane has the least precedent.  But in my organic chemistry book, it doesn't mention the ranking and order of the side chains.
