Optimization of Hybrid Hub-and-Spoke Network Operation for Less-Than-Truckload Freight Transportation considering Incremental Quantity Discount

Centralized Carrier Collaboration Multihub Location Problem for Less-Than-Truckload Industry Hybrid Hub-and-Spoke Network

of profitability, spatially spread demand, and intense competition have incited a trend to seek solutions through ICT and the Internet (3). One manifestation of this is an increase in collaboration among small to medium-sized LTL carriers. That is, small to medium-sized carriers have begun to develop strategies that exploit synergies (such as excess capacity, overlapping lanes, and facilities),...

Modeling of Collaborative Less-than-truckload Carrier Freight Networks

Collaborative Transportation Planning of Less-Than-Truckload Freight: Request Exchange through a Route-based Combinatorial Auction

Collaborative transportation planning (CTP) within a coalition of small and mid-sized freight carriers can be used as a powerful instrument to improve the operational efficiency of the coalition members. In such coalitions, transportation requests acquired from different freight carriers are exchanged among coalition members in order to reduce the total fulfillment costs. We consider the CTP fo...

Patterns of Freight Flow and Design of a Less-than-Truckload Distribution Network

Quantity discount with freight consolidation

We study an integrated quantity discount and vehicle routing problem where truck utilization is increased by building multi-stop routes and increasing order sizes through a purchase incentive. We model the problem and prove it to be NP-hard. Our experiments show that commercial solvers do not effectively solve instances with more than ten buyers. We propose the use of non-compromising route eli...
