Abstract
AbstractThe mixed capacitated general routing problem (MCGRP) is defined over a mixed graph, for which some nodes, arcs, and edges must be serviced. The problem consists of determining a set of routes of minimum cost that satisfy the demand. Some problems like salt spreading have a time‐dependent demand which was ignored in the previous studies. This variation of demand is due to the weather or traffic conditions. This study presents a mixed integer programming model without graph transformation to node routing. We use CPLEX to solve small instances and we develop a Slack Induction by String Removals metaheuristic for large instances adapted to this problem. The proposed model and metaheuristic were tested on problems derived from a set of classical instances of the MCGRP with some modifications to include time‐dependent demands.
