One real life problem in math is calculating the optimal route for a delivery driver to save time and money on gas. This problem is known as the Vehicle Routing Problem (VRP), which is a type of combinatorial optimization problem.
According to the American Mathematical Society, “The VRP is one of the most difficult combinatorial optimization problems and, at the same time, one of the most important. This is due to the fact that the VRP can be found in a variety of applications in real life”. Such applications include logistics, transportation, and supply chain management.
The goal of the VRP is to determine a set of routes that minimizes the total distance or time traveled by a fleet of vehicles in order to serve a set of customers with known demands at different locations. This problem becomes increasingly complex as the number of customers and vehicles increases.
One approach to solving the VRP is the use of heuristics or algorithms designed to find good solutions quickly, although not necessarily optimal. For instance, the famous Nearest Neighbor algorithm works by selecting a starting point and then choosing the nearest unvisited location until all customers are served.
In modern times, VRP has become even more important as online shopping and home deliveries become increasingly popular. As noted by Giovanni Rinaldi, a mathematician and pioneer in VRP research, “In recent years the problem has gained renewed attention due to the emergence of new areas of application and to the availability of unprecedented computing power.”
To illustrate the complexity of the VRP, below is a table showing the distances between various customers and the time it would take to travel between them in a hypothetical scenario with 6 customers and 2 vehicles:
| Customer | 1 | 2 | 3 | 4 | 5 | 6 |
|---|---|---|---|---|---|---|
| 1 | – | 5 (10) | 4 (8) | 6 (12) | 4 (8) | 2 (4) |
| 2 | 5 (10) | – | 2 (4) | 3 (6) | 5 (10) | 9 (18) |
| 3 | 4 (8) | 2 (4) | – | 7 (14) | 2 (4) | 1 (2) |
| 4 | 6 (12) | 3 (6) | 7 (14) | – | 6 (12) | 5 (10) |
| 5 | 4 (8) | 5 (10) | 2 (4) | 6 (12) | – | 3 (6) |
| 6 | 2 (4) | 9 (18) | 1 (2) | 5 (10) | 3 (6) | – |
The numbers along the diagonal represent the distance/time of traveling from a customer to themselves (which is impossible), while the numbers in parentheses represent the round-trip distance/time in each case. Notice that the distances/times are not necessarily the same for every pair of customers due to factors such as traffic, road conditions, and road congestion.
