Because of its great utility in modern transport systems, the DVRP is now a very motivating and still attractive line of research for new studies. The complexity of this problem comes from the fact that it belongs to the VRP family in addition to the dynamism of its components. In this article, a very little studied variant of the DVRP is dealt with. This is the multi-tour DVRP with overtime (MTDVRPOT). We treat this problem from a multi-objective point of view, based on a bi-objective mathematical modelling. The first objective is to minimise the total travelled distance, while the second objective is to minimise to maximal performed overtime. A heuristic based on the iterative exact method was proposed to solve this problem. Its principle is to divide the working day into time periods and resolve iteratively the mathematical models. Each mathematical model corresponds to one subproblem of one time period.

The first approach is based on an exact method, the second is a hybrid ant colony system, while the third is a memetic algorithm. The tests are performed on small instances, and the results show the efficiency of the memetic algorithm. {\textcopyright} 2020 IEEE.}, keywords = {Ant colony optimization, Comparative studies, Dynamic vehicle routing problems, Exact methods, Hybrid ant colony systems, Memetic algorithms, Multi trips, Vehicle routing, Vehicles}, doi = {10.1109/GOL49479.2020.9314727}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-85100211299\&doi=10.1109\%2fGOL49479.2020.9314727\&partnerID=40\&md5=b18f63526f7e1ac4b3feb37e42ce0faa}, author = {Ouaddi, K. and Mhada, F.-Z. and Benadada, Y.} } @conference {Benadada2020, title = {Foreword}, booktitle = {Proceedings - 2020 5th International Conference on Logistics Operations Management, GOL 2020}, year = {2020}, note = {cited By 0}, doi = {10.1109/GOL49479.2020.9314742}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-85100213701\&doi=10.1109\%2fGOL49479.2020.9314742\&partnerID=40\&md5=13d6605e4e394d8af7eb3cbeec9515f1}, author = {Benadada, Y. and Mhada, F.-Z.} } @article {Ouaddi2020643, title = {Memetic algorithm for multi-tours dynamic vehicle routing problem with overtime (Mdvrpot)}, journal = {International Journal of Industrial Engineering Computations}, volume = {11}, number = {4}, year = {2020}, note = {cited By 8}, pages = {643-662}, abstract = {After three decades of its introduction, the dynamic vehicle routing problem (DVRP) remains a fertile field for new studies. The technological evolution, which continues to progress day by day, has allowed better communication between different actors of this model and a more encouraging execution time. This encouraged researchers to investigate new variants of the DVRP and use more complicated algorithms for the resolution. Among these variants is the multi-tour DVRP (MTDVRP) with overtime (MTDVRPOT), which is the subject of this article. This paper proposes an approach with a memetic algorithm (MA). The results obtained in this study are better than those of the ant colony system (ACS) applied to the same problem and published in an earlier paper. {\textcopyright} 2020 by the authors; licensee Growing Science, Canada.}, doi = {10.5267/j.ijiec.2020.4.001}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-85090725004\&doi=10.5267\%2fj.ijiec.2020.4.001\&partnerID=40\&md5=d438b38f932a7acfddc0489585ccfa79}, author = {Ouaddi, K. and Mhada, F.-Z. and Benadada, Y.} } @article {Ouaddi2018306, title = {Ant colony system for dynamic vehicle routing problem with overtime}, journal = {International Journal of Advanced Computer Science and Applications}, volume = {9}, number = {6}, year = {2018}, pages = {306-315}, doi = {10.14569/IJACSA.2018.090644}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-85049537762\&doi=10.14569\%2fIJACSA.2018.090644\&partnerID=40\&md5=05f62f74b7943a59ae4ebc2b7d73e82e}, author = {Ouaddi, K. and Benadada, Y. and Mhada, F.-Z.} } @conference {Ouaddi2016, title = {Multi period dynamic vehicles routing problem: Literature review, modelization and resolution}, booktitle = {Proceedings of the 3rd IEEE International Conference on Logistics Operations Management, GOL 2016}, year = {2016}, note = {cited By 0}, abstract = {Being member of the VRP family, the Dynamic VRP (DVRP) has been a topic of interest in the realm of research, especially in the last decade. The steps of resolution were based on various approaches, ranging from the exact meta-heuristic to customized methods. This paper presents a literature review of the DVRP by classifying relevant studies according to the adopted approach of resolution. The dynamic extension of a version already present in the literature of the turned VRP multi classical is described then. A mathematical modeling is proposed for this extension. For the resolution of our problem, we adopted an approach based on the system of the colony of ants. {\textcopyright} 2016 IEEE.}, doi = {10.1109/GOL.2016.7731706}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-85001930738\&doi=10.1109\%2fGOL.2016.7731706\&partnerID=40\&md5=a7ddfd023d856f524eb379bb4ae1805a}, author = {Ouaddi, K. and Benadada, Y. and Mhada, F.-Z.} }
