Pick up drop off problem on fixed / dynamic route
If the routes are fixed and pre-defined, the problem can be reduced to a container loading problem or a variant of a bin-packing problem. In both cases, the orders might be split and assigned to the v …

What is the following VRP?
Would you see, Multiple Traveling Salesman Problem (mTSP). I think with add some limitation (as your constraints), it might be useful.

What is the state-of-art (in industry and academy) of this scheduling + routing problem?
Besides other useful answers, there is a nice introduction for Technician Routing and Scheduling Problem which has been found in the Gurobi host.
About the existing application, by googling you can ea …

Number of paths in asymmetric capacitated vehicle routing problem
I am pretty sure, this is not the best way to tackle such a problem, specifically from the computational complexity point of view, but at least it might be represented as an effort to solve small-scal …

How to remove or replace sub tour elimination constraints in the VRP variant models?
In many of vehicle routing problems variant (VRP), which can be formulated using MIPs, to avoid creating sub tour, we need to use sub tour elimination constraints (SEC). One of the known SEC is (I als …

Can I formulate a green vehicle routing problem with pyomo model then solve it with metaheur...
If you are interested to write the problem as a standard formulation, like mixed-integer linear programming, you can use Pyomo as a framework and solve the problem in an exact manner with your favorit …
