This repository contains the implementation of an innovative approach to optimizing warehouse locations for e-commerce platforms through geospatial clustering techniques. The project leverages advanced spatial clustering and optimization algorithms to identify optimal warehouse locations that improve delivery speed, reduce costs, and enhance customer satisfaction.
Efficient warehouse placement is crucial for the operational efficiency of e-commerce businesses. This project introduces a method that uses density-based spatial clustering combined with optimization techniques, leveraging real-world geolocation data to streamline e-commerce logistics.
- Geospatial Clustering: Utilizes density-based spatial clustering of applications with noise (DBSCAN) and its hierarchical version (HDBSCAN) to identify high-demand areas.
- Optimization Model: Integrates travel distances and durations derived from the Google Maps API into the optimization process, utilizing Random Optimization (RO) techniques to fine-tune warehouse locations.
- Dynamic Weight Parameters: Incorporates variable weight parameters for distance metrics, allowing customization based on geographic and demographic factors.
The model begins with an application of density-based spatial clustering algorithms, specifically DBSCAN and HDBSCAN, to analyze and segment geolocation data into clusters indicative of high customer density. This initial clustering provides a foundational sketch of potential warehouse locations.
Following the spatial clustering phase, the model transitions into an optimization stage where the identified potential locations are refined for logistical efficiency and cost-effectiveness. This optimization phase leverages several advanced Random Optimization (RO) techniques:
- Particle Swarm Optimization (PSO): Used for its efficacy in navigating multi-dimensional search spaces, PSO adjusts the coordinates of potential warehouse locations by simulating a social behavior among particle agents that 'swarm' towards optimal solutions.
- Nelder-Mead Algorithm: Employs a simplex of points in the solution space to find the minimum or maximum of a function without the need for gradients, which is particularly useful for problems involving noisy measurement data.
- Simulated Annealing (SA): This probabilistic technique is used to approximate the global optimum of a given function, ideal for finding efficient solutions in large search spaces with numerous local optima.
These RO techniques are integrated with the Google Maps API, which provides real-time data on travel distances and durations. The optimization considers these factors, along with the weight parameters optimized for each distance metric, to finalize the warehouse locations that best reduce delivery times and operational costs.
