Optimization of Heterogeneous Fleet Vehicle Routing Problem (HVRP) using Google Ortools Solver

Objective of the model is to create routes such that:

• Number of vehicles used are minimized
• Travel is minimized
• Cost of not-serving order is minimized

Subject to constraints such as:

• Different end times for vehicles
• Max waiting for vehicles
• Different start times for vehicles
• Different service times for vehicles
• Different travel times for vehicles
• Different capacity restrictions for vehicles
• Different max working hours for vehicles
• Time windows for orders
