博士 / 國立成功大學 / 交通管理科學系 / 103 / Zone pricing is a tactical decision that simultaneously determines the zone prices and an operational plan to use its operating capacity to maximize carrier’s profit while meeting the expected service level and operational requirements. We modeled this integral-constrained concave program using link formulation and proposed an implicit enumeration embedded with Lagrangian relaxation upper bounds to determine the optimal prices and operations plan. To meet the shippers’ expectation, we proved our model mathematically and demonstrated computationally, using Taiwan’s largest time-definite LTL freight carrier, that zone pricing has a negative impact on carrier profit in the process of aggregation.
If the operation network is designed to be 3 hubs model, the best alternative is to open the hubs of Wugu and Yongkang. If the operation network is designed to be 4 or 5 hubs model, the best alternative is to open the hubs of Wugu and Chiayi. The 4 or 5 hubs model will get more profit to 1.5 times than 3 hubs model.
