Run all data generation scripts for the delivery route optimization project. |

|

This function orchestrates the creation of all synthetic datasets needed for |
|
|
the route optimization problem, including delivery data, vehicle data, and |
|
|
travel time/distance matrices. |
|
|
|
|
|
Generated Files: |
|
|
-------------- |
|
|
1. Delivery Data: |
|
|
- Contains information about delivery locations, time windows, packages, etc. |
|
|
- Used to define the delivery stops in the routing problem. |
|
|
|
|
|
2. Vehicle Data: |
|
|
- Contains information about the delivery fleet, capacity, depots, etc. |
|
|
- Used to define the available resources for delivery routes. |
|
|
|
|
|
3. Travel Matrices: |
|
|
- Contains distance and time information between all locations. |
|
|
- Used by the optimization algorithm to calculate route costs. |
|
|
|
|
|
Usage: |
|
|
------ |
|
|
These generated datasets form the foundation of the delivery route optimization |
|
|
application. Together they define: |
|
|
- Where deliveries need to be made (delivery data) |
|
|
- What resources are available for deliveries (vehicle data) |
|
|
- How long it takes to travel between locations (travel matrices) |
|
|
|
|
|
The route optimization algorithm uses these inputs to determine the most |
|
|
efficient assignment of deliveries to vehicles and the optimal sequence of |
|
|
stops for each vehicle. |
