Algorithms for solving routing problems with drones: a systematic literature review

The development of drones in routing solutions is increasing its appearance in the literature. More problem variants and the addition of drones to classical routing problems are being modeled. The high increase of papers in just a few years makes it difficult to track the advances in literature. This paper aims to present a systematic literature review, presenting a compact view of a wide range of years (from 2000 to March of 2025) and answer relevant questions about the state-of-the-art such as the most recurrent studied variants, most used methods to solve the problem, and other questions. The complete systematic protocol is presented. The literature revision is highly important in guiding promising and new leads and also prevents the proposal from being what was already proposed.
