To reduce the logistic cost and carbon emission improve customer satisfaction, this study proposes a multiobjective green time-dependent location routing problem (MOGTDLRP) model in which objectives are to minimize distribution total cost, delivery time, fuel consumption. This will be solved by several hyperheuristic algorithms include high-level heuristics low-level heuristics. There three acc...

One of the most important extensions of the capacitated vehicle routing problem (CVRP) is the vehicle routing problem with simultaneous pickup and delivery (VRPSPD) where customers require simultaneous delivery and pick-up service. In this paper, we propose an effective ant colony optimization (EACO) which includes insert, swap and 2-Opt moves for solving VRPSPD that is different with common an...

Electric vehicle routing problems can be particularly complex when recharging must performed mid-route. In some applications such as the e-commerce parcel delivery truck routing, however, mid-route may not necessary because of constraints on capacities and maximum allowed time for delivery. this study, we develop a mixed-integer optimization model that exactly solves time-constrained capacitate...

 We consider a pickup and delivery vehicle routing problem (PDP) commonly find in real-world logistics operations. The problem includes a set of practical complications that have received little attention in the vehicle routing literature. In this problem, there are multiple vehicle types available to cover a set of transportation orders, each of which has pickup time windows and delivery time...
