Abstract

In the context of the DigiLab4U international project, this paper describes a simulation-based serious game that can be used as a virtual teaching lab in higher education courses, especially in Industrial and Systems Engineering, Data Science, Management Science and Operations Research, as well as Computer Science. The learning activity focuses on understanding distribution logistics problems related to transportation optimization using different techniques. These optimization challenges include the vehicle routing problem, the arc routing problem, and the team orienteering problem. As a result of the learning process in the virtual lab, it is expected that students acquire competencies and skills related to logistics and transportation challenges as well as problem-solving. These competencies and skills can be precious for students’ future careers, since they increase students’ analytical skills, capacity to understand heuristic-based algorithms, teamwork and interdisciplinary communication skills, programming skills, and statistical abilities. A preliminary version of this training activity has already been used in MSc and PhD courses held at universities in Spain, Italy, Ireland, and Portugal.

Highlights

  • It is expected that the economic impact of the Internet of Things (IoT) will be between 3.9 and

  • Routing problems can be classified into: (i) node routing problems, such as the vehicle routing problem (VRP) and the team orienteering problem (TOP), where nodes in a network can represent customers, and (ii) edge routing problems, such as the arc routing problem (ARP), where the service is performed on the arcs or edges of a network

  • Similar to the savings-based heuristic for the arc routing problem (SHARP), the Panadero and Juan savings heuristic (PJS) [46] adapts and extends the Clarke and Wright savings (CWS) heuristic considering the peculiarities of the TOP, such as the fact that origin and destination are different, the possibility to avoid visiting some nodes, and the customers’ rewards

Summary

Introduction

Digitalization is changing business and industrial environments worldwide. It is expected that the economic impact of the Internet of Things (IoT) will be between 3.9 and. They established a research project for integrating IoT in higher education called Open Digital Lab for You (DigiLab4U for short) In this project, physical laboratories are digitalized and connected virtually with other laboratories, offering virtual laboratories to students and researchers. The game handles popular transportation and logistics challenges (mainly related to distribution logistics processes) The game is structured to train the basic skills and offer the required knowledge to handle the described problems (Section 3.3). Authors translate their knowledge in solving these problems to students in this structure.
