Production phases question

Hello everyone
Could you help me to understand these fields:

What are min capacity & max capacity?
And where do I need to input the phase duration? I guess ‹ Duration\cycle ›, but than what ‹ timing of implementation › means?

Maybe you can share some example what you input in these fields?

min Capacity : Minimum capacity for completion of the phase at each cycle
max Capacity : Maximum capacity for completion of the phase at each cycle
duration\Cycle : Duration of a production cycle for phase
