Many logistic activities are concerned with linking material flows among companies and processes. In such applications, we find a combination of quantity decisions, e. g. the amount of goods shipped (Inventory Management), and routing decisions as tackled in the area of Vehicle Routing. Clearly, both areas intersect to a considerable degree, complicating the solution of such problems. Recently,...

Logistic activities, from a certain point of view, are often structured around two concepts, the transportation of goods and the management of the same goods. Of course, these two activities are highly interlinked. It is possible to combine at the same time the problem of defining the amount of goods that have to be shipped (the Inventory Management problem – the quantity decision) and the rout...

In this article, we study an Inventory Routing Problem with deterministic customer demand in a two-tier supply chain. The chain network consists of supplier using single vehicle given capacity to deliver product type multiple customers. We are interested population-based algorithms solve our problem. A Memetic Algorithm (MA) is developed based on the Genetic (GA) and Variable Neighborhood Searc...

We solve a rich logistical problem inspired from practice, in which a heterogeneous xed eet of vehicles is used for collecting recyclable waste from large containers over a nite planning horizon. Each container is equipped with a sensor, which communicates its level at the start of the day. Given a history of observations, a forecasting model is used to estimate the point demand forecasts as we...

We consider a new approach to stochastic inventory/routing that approximates the future costs of current actions using optimal dual prices of a linear program. We obtain two such linear programs by formulating the control problem as a Markov decision process and then replacing the optimal value function with the sum of single-customer inventory value functions. The resulting approximation yield...

This thesis describes a stochastic ship routing problem with inventory management. The problem involves finding a set of least costs routes for a fleet of ships transporting a single commodity when the demand for the commodity is uncertain. Storage at consumption and supply ports is limited and inventory levels are monitored in the model. Consumer demands are at a constant rate within each time...
