[Grammar] What is this, I would call it, possesive form?

[Oidaladno]

Hello.
Cold you pleas help me to understand the miracle o belonging in the glorious language of English.
How are forms like these possible:
time management
business process modelling?
What part of speech is time here? Why do they use it instead management of time?

Bonus question:
Obviously you have nothing against forms like
The Order of Knights of the Hospital of Saint John of Jerusalem
So there's no need for avoiding too many of's, is it?

In time management, "time" is an attributive noun, which is a noun acting as an adjective.

It's fine to use of as often as necessary.
