Nie znam kontekstu tej wypowiedzi, ale zakładam, że można powiedzieć to w ten sposób:

I do not know the pattern/plan/scheme your company uses to organise arrivals and departures for business clients.

bardzo dziekuję za pomoc !!!

I am not aware of your company arrivals and departures scheme for business customers.

"I am not familiar with the plan of arrivals and departures for business clients in your company."
or:
"I am not familiar with your company's arrival and departure scheme for business clients."
"I am not familiar with the scheme your company uses to organize arrivals and departures for business clients."
'I am not aware..." w tym kontekście jest źle.
