Build a simple, single-server queueing model with entity interarrival times of EXPO(0.25) minutes. Using the ReadWrite module, prompt and query at the beginning of the simulation run for the server’s process time mean (give a default value of 0.2 minutes). Use this value to establish a uniform distribution on [ a , b ] where a is 10% below the entered mean and b is 10% above the entered mean. Run the simulation until 300 entities have departed the model.
