Abstract
Transportation planning has been established as a key topic in the literature and social production practices. An increasing number of researchers are studying vehicle routing problems (VRPs) and their variants considering real-life applications and scenarios. Furthermore, with the rapid growth in the processing speed and memory capacity of computers, various algorithms can be used to solve increasingly complex instances of VRPs. In this study, we analyzed recent literature published between 2019 and August of 2021 using a taxonomic framework. We reviewed recent research according to models and solutions, and divided models into three categories of customer-related, vehicle-related, and depot-related models. We classified solution algorithms into exact, heuristic, and meta-heuristic algorithms. The main contribution of our study is a classification table that is available online as Appendix A. This classification table should enable future researchers to find relevant literature easily and provide readers with recent trends and solution methodologies in the field of VRPs and some well-known variants.

Summary
We analyzed recent literature published between 2019 and August of 2021 using a taxonomic framework. We restricted the reviewed literature to the following features: only relevant articles published in English-language journals were considered, meaning books, conference proceedings, and dissertations were excluded. The search was limited to articles that were extended by highly cited articles published in any ranked journal (Google Scholar top 20), excluding review papers. The abstracts of selected articles were read to determine their relevance to the subject This search strategy resulted in a final set of 88 articles. This selection is not exhaustive, it contains the majority of recent articles on VRPs and can be considered as representative of the field
