Model the system described below: A simple public hospital system may be described as follows: Patients arrive to the hospital for medical checks. They will first be interviewed by a nurse and thereafter a medical check will be made by the doctor. Based on the result of the check 50% of the patients will undergo a small operation performed by the doctor assisted by a nurse and then leave the hospital. Those which do not need an operation leave after the check. There are two nurses and one doktor. The patient arrivals are negative exponential with mean time 45 minutes. The interview takes 10 minutes, the check from 10 to 15 minutes, and an operation 20-40 minutes to perform (both uniformly distributed). Question 1: Draw this scenario using following modeling technique. a) Control Flow Pattern b) Petri Nets c) Event Driven Process Chain d) Graph Based Workflow e) Business Process Model and Notation
