4. Specifying the MM1 Queue

In order to specify the M/M/1 queue and its characteristics, a file mm1_queue.py has to be developed.

# mm1_queue.py

import numpy as np

class MM1Queue:

def __init__(self, arrival_rate, service_rate, max_time):

self.arrival_rate = arrival_rate

self.service_rate = service_rate

self.max_time = max_time

self.reset()

def reset(self):

self.current_time = 0

self.next_arrival_time = self.generate_interarrival_time()

self.next_departure_time = float(‘inf’)

self.queue = 0

self.total_customers = 0

self.total_waiting_time = 0

self.total_system_time = 0

self.total_idle_time = 0

self.num_customers_served = 0

self.arrival_times = []

self.departure_times = []

self.queue_lengths = []

def generate_interarrival_time(self):

return np.random.exponential(1 / self.arrival_rate)

def generate_service_time(self):

return np.random.exponential(1 / self.service_rate)

def simulate(self):

while self.current_time < self.max_time:

if self.next_arrival_time < self.next_departure_time:

self.handle_arrival()

else:

self.handle_departure()

def handle_arrival(self):

self.current_time = self.next_arrival_time

self.queue += 1

self.total_customers += 1

self.arrival_times.append(self.current_time)

if self.queue == 1:

self.next_departure_time = self.current_time + self.generate_service_time()

self.next_arrival_time = self.current_time + self.generate_interarrival_time()

self.queue_lengths.append((self.current_time, self.queue))

def handle_departure(self):

self.current_time = self.next_departure_time

self.queue -= 1

self.num_customers_served += 1

self.departure_times.append(self.current_time)

if self.queue > 0:

self.next_departure_time = self.current_time + self.generate_service_time()

else:

self.next_departure_time = float(‘inf’)

self.queue_lengths.append((self.current_time, self.queue))

def calculate_performance_metrics(self):

if self.num_customers_served > 0:

self.total_waiting_time = sum(self.departure_times) – sum(self.arrival_times)

self.total_system_time = self.total_waiting_time + sum([self.generate_service_time() for _ in range(self.num_customers_served)])

avg_waiting_time = self.total_waiting_time / self.num_customers_served

avg_system_time = self.total_system_time / self.num_customers_served

avg_customers_in_queue = np.mean([length[1] for length in self.queue_lengths])

else:

avg_waiting_time = 0

avg_system_time = 0

avg_customers_in_queue = 0

return avg_waiting_time, avg_system_time, avg_customers_in_queue

5. Main Simulation Loop

In the main.py file, the major simulation loop should be developed.

# main.py

import numpy as np

import matplotlib.pyplot as plt

from mm1_queue import MM1Queue

def main():

# Parameters

arrival_rate = 1.0  # Average arrival rate (lambda)

service_rate = 1.5  # Average service rate (mu)

max_time = 1000     # Total simulation time

# Create M/M/1 Queue

mm1_queue = MM1Queue(arrival_rate, service_rate, max_time)

# Run simulation

mm1_queue.simulate()

# Calculate performance metrics

avg_waiting_time, avg_system_time, avg_customers_in_queue = mm1_queue.calculate_performance_metrics()

# Print results

print(f”Average waiting time: {avg_waiting_time:.4f}”)

print(f”Average time in system: {avg_system_time:.4f}”)

print(f”Average number of customers in queue: {avg_customers_in_queue:.4f}”)

# Plot queue length over time

times, queue_lengths = zip(*mm1_queue.queue_lengths)

plt.figure(figsize=(10, 6))

plt.plot(times, queue_lengths, drawstyle=’steps-post’)

plt.xlabel(‘Time’)

plt.ylabel(‘Queue Length’)

plt.title(‘Queue Length over Time in M/M/1 Queue’)

plt.grid(True)

plt.show()

if __name__ == “__main__”:

main()
