We compare two iterative methods for solving the Planar Single-Facility Location-Routing Problem (PSFLRP), involving optimizing the continuous-valued location of a single depot by iteratively solving instances of the Vehicle Routing Problem (VRP). An Ant Colony Optimization (ACO) algorithm is used for solving the routing problem, a procedure using Weiszfeld's algorithm and a simple Evolution Strategy...
Most research into the Container Loading problem has been done on theoretical problem sets and while taking one or two constraints into account. In this paper we discuss the successful implementation of a self-adaptive Genetic Algorithm applying only mutation, with a variable mutation rate. This is applied to a real-world problem with actual problem instances from industry. We introduce an abstract,...
Truck Loading Optimization problems from practice tend to involve a lot of constraints. In automatically solving these problems, a rule set has to be compiled that governs the generation of valid solutions. This rule set is either defined manually, or distilled automatically by analyzing solutions of human planners. This paper describes the extension of an existing optimization approach with statistics...
