My humble understanding is such:
Allocation - means allot a fraction of something to someone.
Allocation can be achieved by assessment or distribution.
I am puzzled what is meant by assessment. What is there to assess? Why assess?
Can I say that there must be a key used for distribution? can it be % (totalled to 100%) or ratio (totalled to 1) ?
As you can see, I am total greenhorn in this area.
Please help me, if you can. I promise to award points for the best clearest answers.
