In the 2L-CVRP with pickup and delivery constraints, delivery items are unloaded and additional pickup items are loaded onto the vehicle. Likewise, the VRP with pickup and delivery (PD) and 2D loading constraints is only researched in two works. The first one is proposed by Malapert et al. (2008) for solving the 2L-VRPPD. The second one is introduced by Zachariadis et al. (2016), the VRP with simultaneous pickup and delivery (2L-SPD) with LIFO constraints using a local search algorithm.
