Let's create visualizations to understand the VRPTW problem structure and solution characteristics.

Out[6]:
Visualization
Spatial map showing depot and 15 customer locations for VRPTW problem instance.
VRPTW problem layout showing the depot (red square) and 15 customer locations (blue circles) distributed across the service area. Each customer has a demand that must be satisfied and a time window for service.
Horizontal bar chart showing time window constraints for each of the 15 customers.
Customer time windows showing the service availability periods for each customer. The horizontal bars represent the time range during which each customer can be served. Overlapping windows create flexibility in route sequencing.
Out[7]:
Visualization
Spatial routes map showing three different colored vehicle routes connecting depot to 15 customer locations, forming efficient delivery paths.
Sample VRPTW solution showing three vehicle routes serving 15 customers. Each color represents a different vehicle's route, starting and ending at the depot (black square). The routes are designed to minimize total travel distance while respecting capacity constraints and customer time windows.
