[SHARP] Metaheuristic Optimization - P Median Problem

This repository contains the Jupyter notebooks, text files, and supporting documentation for the project activity on the p-median location problem. The objective of this project is to determine the optimal selection of facilities from a set of potential locations, minimizing the total distance for serving all demand points while ensuring that each demand point is assigned to its nearest selected facility.

Problem Overview

Given a set of n locations representing demand points and a set of m potential facility locations, the p-median problem aims to determine the optimal selection of p facilities from the set of potential locations.

Instances

• Instance 1: 100 locations, requiring 15 facilities to be open.
• Instance 2: 1000 locations, requiring 30 facilities to be open.
