To the extent that axiology is about values (what is good/bad), it is about preferences (what would one rather do), and is thus tied to decision theory in that it offers the place from which numbers gets assigned to different decisions even if it doesn’t say how to choose among them. I assume most people are familiar with preferences and it may or may not be very relevant for your work as it’s already pretty similar to issues in morality that requires choosing between options, but thought it worth mentioning.
