The location routing problem (LRP) integrates operational decisions on vehicle operations with strategic the of facilities or depots from which distribution will take place. In other words, it combines well-known (VRP) facility (FLP). Hence, LRP is an NP-hard combinatorial optimization problem, justifies use metaheuristic approaches whenever large-scale instances need to be solved. this paper, ...
The latency location routing problem (LLRP), a combination of the facility and cumulative capacitated vehicle problem, is recently proposed variant problems. It corresponds to customer-centric in which aim minimize sum arrival times at customers. This paper proposes three novel metaheuristic algorithms solve LLRP. They use simulated annealing framework, after each temperature reduction intensif...
The increasing demand for multimodal freight transportation makes the expansion of new secondary hubs necessary. carbon tax has also received attention from various sectors due to development requirements green transportation. Therefore, this study proposed a transport hub location problem, where emissions are specifically considered achieve strategic planning. A mixed integer non-linear progra...
Facility location decisions play a prominent role in strategic planning of many firms, companies and governmental organizations. Since in many real-world facility location problems, the data are subject to uncertainty, in this paper, we consider the P-center problem under uncertainty of demands. Using Bertsimas and Sim approach, we develop a robust model of the problem as an integer programming...
