A DSS for the multi-criteria Vehicle Routing Problem with pickup and delivery and 3d constraintsA DSS for the multi-criteria Vehicle Routing Problem with pickup and delivery and 3d constraints Πλήρης Δημοσίευση σε Συνέδριο Conference Full Paper 2024-11-202022enThe Vehicle Routing Problem (VRP) with three-dimension (3D) constraints (3L-CVRP) is a variant of the VRP with many possible applications in real-world scenarios. The purpose of this paper is to propose a Decision Support System for the VRP with pickup and delivery and 3D constraints (3L-CVRP-PD), considering multiple criteria. A Graphical User Interface (GUI) is developed, aiming to provide a better interaction experience with the software. The GUI includes a 3D representation of the loading bay for each vehicle, a feature that makes solutions easier to comprehend. The routing segment of the 3L-CVRP-PD is solved using a heuristic method, while item packing takes place in an exhaustive manner and multiple solutions are generated for each problem. The solutions are ranked by a Multi-Criteria Decision Method (MCDM). Two MCDMs are tested in this paper, the Preference Ranking Organization Method for Enrichment of Evaluations (PROMETHEE) and the UTility Additives* (UTASTAR), on modified instances from the literature.http://creativecommons.org/licenses/by/4.0/177–1898th International Conference on Decision Support System TechnologyDecision Support Systems XII: Decision Support Addressing Modern Industry, Business, and Societal Needs Stamadianos Themistoklis Σταμαδιανος Θεμιστοκλης Marinaki Magdalini Μαρινακη Μαγδαληνη Matsatsinis Nikolaos Ματσατσινης Νικολαος Marinakis Ioannis Μαρινακης Ιωαννης Springer Nature Vehicle routing problem Multi-criteria VRP Three dimensional loading Graphical user interface
