Algorithm to establish a global ranking given individual rankings

Question

I am looking for an algorithm(s) that can compute a global ranking (partial ordering) given individual rankings, in some kind of principled manner.

I want to establish a partial-ordering of some projects, and had some users create their own partial orderings.

I've looked at these algorithms so far:

• borda-0
• borda-1
• Dowdall

My problem is that these algorithms were not really designed to establish partial-ordering and are instead for choosing N winners. I haven't been able to find any widely-used algorithms for this purpose.

I looked at adapting STV to this purpose, but raw STV gives no instructions on how to resolve ties, and it's unclear to me what properties it would have when applied to partial ordering.

Is there a widely-used algorithm/family of algorithms for the problem?
