We present a method for solving the transshipment problem---also known as uncapacitated minimum cost flow---up to multiplicative error of $ 1 + \varepsilon in undirected graphs with nonnegative...

We provide a new approach to the analysis of the optimal joint inventory and transshipment control with uncertain capacities by employing the concept of L-convexity. In this approach, we use variable transformation techniques and apply two recent results to establish the L-concavity of the profit-to-go functions, which significantly simplifies the analysis in the existing literature. Some varia...

Transshipment hubs are important components of the global container shipping network. Nowadays, hybrid ports emerging, handling both gateway and transshipment traffic depending on their significant maritime connectivity. Effectively identifying hubs, including traditional with high incidences sufficient capabilities, is crucial to gain a good understanding networks. The method reinforced struct...

We present an optimization model for the yard allocation process in an automotive transshipment terminal. The cars arrive and depart by ships in large batches and the yard planners have to dynamically assign incoming cars to parking rows. The integer linear programming model has been implemented in a commercial solver (CPLEX). We will present at the conference the model, the CPLEX computational...

ABSTRACT We consider coordination among stocking locations through replenishment strategies that explicitly take into account lateral transshipments, i.e., transfer of a product among locations at the same echelon level. The basic contribution of our research is the incorporation of supply capacity into the traditional emergency transshipment model. We formulate the capacitated production case ...

We consider a single-item, two-echelon spare parts inventory model for repairable parts for capital goods with high down time costs. The inventory system consists of a central warehouse and multiple local warehouses, from where customers are served, and a central repair facility at an external supplier. When a part fails at a customer, his request for a ready-for-use part is immediately fulfill...
