In this paper, we propose two heuristics: route first - cluster second, and cluster first - route second, to solve the problem efficiently. A new mixed integer programming formulation is also introduced to ...

WebOct 13, 2024 · The second manner is the route-first-cluster-second where vehicle capacity is relaxed to build a TSP called giant tour, then the TSP is break into feasible trips using a split function . The route-first-cluster-second was theoretically proposed in [ 5 ], but the first results for CVRP only were presented in [ 15 ]. WebOct 12, 2024 · In this paper, three cluster-first route-second approaches are proposed to solve the capacitated vehicle routing problem (CVRP) that extends a traveling salesman problem (TSP). In the first phase, a giant tour covering all customers is built using three different metaheuristic algorithms as an ACO, a GA, and an ABCA. Then, the giant tour is … remedio enjoo gravidez dramin b6
