Routing problems — Mathematical Optimization: Solving ...

A vehicle that departed from a specific point called a depot returns to the depot again via multiple customers. In this case, the order of customers passing by the truck is called a route (see Fig. 5.4). In this case, the truck is used as a generic term that refers to various means of transport such as trucks, trailers, and ships.

Savings Algorithm | Vehicle Routing Problem

The Clarke and Wright savings algorithm is one of the most known heuristic for VRP. It was developed on [Clarke and Wright 1964] and it applies to problems for which the number of vehicles is not fixed (it is a decision variable), and it works equally well for both directed and undirected problems.When two routes ${(0,…,i,0)}$ and ${(0,j,…,0)}$ can feasibly be merged into a single route ...
