Despite the fact that there is a large body of literature on Production Routing Problem (PRP), we were struck by dearth research outsource planning and lateral transshipment. This paper presents mixed-integer linear programming model for incorporating outsourcing, transshipment, back ordering, lost sales, time windows into production routing problems. Then robust optimization will be introduced...

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...

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. Our basic contribution is the incorporation of supply capacity into the traditional transshipment model. Our goal is to analyze the impact on system behavior and on stocking locations’ ...

We first present a unged formulation to three problems in VLSI physical design: Layout compaction, Wire balancing and Integrated layout compaction and wire balancing problems. The aim of layout compaction is to achieve minimum chip width. Whereas wire balancing seeks to achieve minimum total wire length, integrated layout compaction and wire balancing seeks to minimize wire length maintaining t...
