In this paper a different approach OFSTF (Origin, First, Second, Third, and Fourth quadrants) Method is applied for finding a feasible solution for transportation problems directly by having non linear to linear equation conversion technique. The proposed method is a unique, it gives always...

We extend the classical Pickup and Delivery Problem (PDP) to an integrated routing and two-dimensional loading problem, called PDP with two-dimensional loading constraints (2L-PDP). A set of routes of minimum total length has to be determined such that each request is transported from a loading...

The present paper studies a generalization of the less-than-truckload pickup and delivery problem. The problem at hand arises in the hinterland of container terminal where empty and loaded containers have to be transported between a container depot and a set of customer locations. However,...
