9999 MEANS INFINITY

We consider the following self explanatory variables: TM = clock time of the simulation AT = scheduled time of the next arrival DT = scheduled time of the next departure SS = status of the server (1 = busy, 0 = idle) WL = length of the queue MX = length (in time units) of the simulation run IT = interarrival time ST = service time

Question 4 At a certain COVID19 vaccination site in Pretoria the arrival times (in minutes) and service times (in minutes) for the first 10 people arriving for vaccination were as follows: Arrival times : 10; 29; 61; 93; 97; 152; 176; 219; 302; 343 Service times : 38; 30; 53; 46; 16; 48; 22; 10; 70; 28. Service time includes data capturing done by support staff and the actual vaccination. Upon arrival, a person either enters service if support staff is free or joins the waiting line. There is always one person for data capturing (support staff) and one nurse on duty responsible for vaccination. 4.1 Simulate the system using the arrival (arrival times, not interarrival times) and service times given. Present your calculations in the table below.
