On AIX there is something similar for use rpm?

AIX Open Source Packages | FAQs / FAQs (Frequently Asked Questions)
As Michael Perzl says on his site (the link you quoted) yum needs rpm version 4.4 and above. AIX uses rpm version 3, so there is no real remedy for this. MP offers a - not ideal, but feasible - remedy: cycle through the packages, listing every prerequisite of each, collect the output into file and use sort and uniq to remove duplicates.
AIX has its own packaging system (installp) and rpm was just included as an effort to "look open", back then in ~2000 with AIX 5 and the "Linux compatibility Initiative". This was more a marketing hype by IBM than a genuine effort to make their product better. It stll is.
I hope this helps.
