Abstract
This paper considers a double-trailer drop-and-pull container drayage (DTDPCD) problem optimizing the number of employed vehicles. In the DTDPCD problem, a tractor is allowed to carry up to two trailers, trailers can be detached from the tractor during packing / unpacking operations. A mixed integer nonlinear programming model is built based on graphical formulation. The model is linearized so that it can be solved using optimizing software such as CPLEX. Computational results based on randomly generated instances show that tractors pulling two trailers can save transportation costs by 13.40% and 29.40%, compared to the single-trailer and stay-with scenarios, respectively.
