In this example, you’ll learn how to use mathematical optimization to solve a vehicle routing problem with time windows, which involves helping a company figure out the minimum number of vans required to deliver pieces of lost or delayed baggage to their rightful owners and determining the optimal assignment of vans to customers.
This model is example 27 from the fifth edition of Model Building in Mathematical Programming by H. Paul Williams on pages 287-289 and 343-344.
This modeling example is at the advanced level, where we assume that you know Python and the Gurobi Python API and that you have advanced knowledge of building mathematical optimization models. Typically, the objective function and/or constraints of these examples are complex or require advanced features of the Gurobi Python API.
