Simulate Poisson Process Python

Simulate Poisson Process Python is like designing a series of incidents that are occurring randomly in a periodic manner, in which the duration among every incident adheres to an exponential distribution, is the main function of a Poisson process which is considered as a stochastic process. In order to design the event of random incidents periodically, it is generally employed in domains like queuing theory, finance, and telecommunications:

We suggest a procedural instruction to simulate a Poisson process in Python in an effective manner:

Step 1: Install Necessary Libraries

We plan to utilize matplotlib for visualization and numpy for numerical processes, in this simulation. When we don’t have already, it is advisable to install them with the aid of pip:

pip install numpy matplotlib

Step 2: Write the Poisson Process Simulation Code

The following is a basic Python script to simulate a Poisson procedure efficiently:

import numpy as np

import matplotlib.pyplot as plt

# Parameters for the Poisson process

lambda_rate = 5  # Rate of the Poisson process (events per time unit)

time_end = 10    # Time period for the simulation

# Simulate inter-arrival times

inter_arrival_times = np.random.exponential(1/lambda_rate, size=1000)

arrival_times = np.cumsum(inter_arrival_times)

# Select only the events within the time_end period

arrival_times = arrival_times[arrival_times <= time_end]

# Plot the Poisson process

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

plt.step(np.concatenate([[0], arrival_times]), np.arange(len(arrival_times)+1), where=’post’)

plt.title(‘Poisson Process Simulation’)

plt.xlabel(‘Time’)

plt.ylabel(‘Number of Events’)

plt.grid(True)

plt.show()

Step 3: Run the Simulation

1. The code must be saved as poisson_process.py.
2. With the support of Python, we execute the script:

python poisson_process.py

Step 4: Customize the Simulation

In several ways, we are able to prolong and adapt this simple simulation:

• Different Rate Parameter: In order to simulate Poisson procedures with various event rates, we focus on varying the lambda_rate.
• Multiple Realizations: Numerous realizations of the Poisson procedure ought to be simulated. To examine the changeability, our team plans to plot them collectively.
• Histogram of Inter-Arrival Times: A histogram of the inter-arrival times has to be plotted to validate that they adhere to an exponential distribution.
• Non-Homogeneous Poisson Process: Periodically, in the event that the rate parameter changes, it is advisable to simulate a non-homogeneous Poisson procedure.
• 3D Visualization: To investigate the distribution of incidents, we intend to visualize several realizations of the Poisson’s procedure in a 3D plot.

Description of the Code

• Lambda Rate: The rate of the Poisson process is indicated by the parameter lambda_rate. Generally, this parameter depicts the average number of incidents per unit time.
• Inter-Arrival Times: The inter-arrival times is described as the time among succeeding incidents in a Poisson procedure which adheres to an exponential distribution. To produce inter-arrival times, our team aims to employ np.random.exponential.
• Arrival Times: Generally, through collectively totaling the inter-arrival times, the arrival times of incidents are estimated.
• Plotting the Process: Through the utilization of a step plot, the Poisson procedure is visualized in which the y-axis depicts the cumulative number of incidents and the x-axis demonstrates the time.

Instance: Non-Homogeneous Poisson Process

The following is an instance based on how we could simulate a non-homogeneous Poisson procedure in which the rate parameter varies periodically:

def non_homogeneous_rate(t):

return 5 + 2 * np.sin(2 * np.pi * t / time_end)

# Generate non-homogeneous Poisson process

arrival_times = []

current_time = 0

while current_time < time_end:

rate = non_homogeneous_rate(current_time)

inter_arrival_time = np.random.exponential(1 / rate)

current_time += inter_arrival_time

if current_time < time_end:

arrival_times.append(current_time)

# Plot the Non-Homogeneous Poisson Process

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

plt.step(np.concatenate([[0], arrival_times]), np.arange(len(arrival_times)+1), where=’post’)

plt.title(‘Non-Homogeneous Poisson Process Simulation’)

plt.xlabel(‘Time’)

plt.ylabel(‘Number of Events’)

plt.grid(True)

plt.show()

Additional Extensions

• Simulate a Poisson Process with Batch Arrivals: As a means to enable numerous incidents to happen at the same time (batch arrivals), it is approachable to alter the procedure.
• Queueing System Simulation: In a queuing model, simulate the arrival of consumers through the utilization of the Poisson procedure.
• Markov Chain Integration: In order to design more complicated models, we plan to incorporate the Poisson procedure with a Markov chain such as a birth-death procedure.
• Jump Process: A jump procedure has to be simulated in which variations in the conditions of a model are generated by the Poisson’s procedure in the same manner as in a financial system.
• Point Process on a Spatial Grid: For simulating incidents on a 3D or 2D grid, our team prolongs the Poisson procedure to a spatial domain.
