Solving NP-Hard Challenges in Logistics and Transportation under General Uncertainty Scenarios Using Fuzzy Simheuristics Juan, Ángel A. Rabe, Markus Ammouriova, Majsa Panadero, Javier Peidro, David Riera Terrén, Daniel Logistics and transportation Metaheuristics Simulation Fuzzy logic In the field of logistics and transportation (L&T), this paper reviews the utilization of simheuristic algorithms to address NP-hard optimization problems under stochastic uncertainty. Then, the paper explores an extension of the simheuristics concept by introducing a fuzzy layer to tackle complex optimization problems involving both stochastic and fuzzy uncertainties. The hybrid approach combines simulation, metaheuristics, and fuzzy logic, offering a feasible methodology to solve large-scale NP-hard problems under general uncertainty scenarios. These scenarios are commonly encountered in L&T optimization challenges, such as the vehicle routing problem or the team orienteering problem, among many others. The proposed methodology allows for modeling various problem components-including travel times, service times, customers' demands, or the duration of electric batteries-as deterministic, stochastic, or fuzzy items. A cross-problem analysis of several computational experiments is conducted to validate the effectiveness of the fuzzy simheuristic methodology. Being a flexible methodology that allows us to tackle NP-hard challenges under general uncertainty scenarios, fuzzy simheuristics can also be applied in fields other than L&T. 2024-11-04T07:19:39Z 2024-11-04T07:19:39Z 2024-11-04T07:19:39Z 2023 Article http://hdl.handle.net/2072/473723 Agencia Estatal de Investigación PDC2022-133957-I00 Agencia Estatal de Investigación PID2022-138860NB-I00 Ministerio de Ciencia e Innovación RED2022-134703-T Algorithms ; Vol. 16, Issue 12 (December 2023), art. 570 open access Aquest document està subjecte a una llicència d'ús Creative Commons.
