Abstract: We study the unilateral transportation problem, a new routing problem originated from the practice of outsourced line-haul transportation in the express delivery industry. Its objective is to find a set of outsourced routes that minimize the total transportation cost, while fulfilling certain transportation tasks and respecting vehicles’ capacities. Particularly, we have considered practical features including heterogeneous vehicles, uncapped demands, and the toll-by-weight scheme. We formulate this problem into a cover set based model, and design both a fast heuristic and an exact algorithm to solve the model. The effectiveness of our algorithms have been demonstrated in the computational experiments.
