Information of solving gear assembly

Hi all,

I am solving a gear assembly problem(15 gear in a assembly). Where I have details of the input RPM and output RPM.

1. In this case what type of analysis we have to carry out when multiple gears rotating?

2.If anyone have any example of solving these kind of problems and how to approach such kind of simulation problems.

Please help

Thank you
