Modeling Demand Uncertainty in Two-Tier City Logistics Tactical Planning

Service network design models for two-tier city logistics

This paper focuses on two-tier City Logistics systems for advanced management of urban freight activities and, in particular, on the first layer of such systems where freight is moved from distributions centers on the outskirts of the city to satellite platforms’ by urban vehicles, from where it will be distributed to customers by other, dedicated vehicles. We address the issue of planning the ...

Logistics capacity planning: A stochastic bin packing formulation and a progressive hedging meta-heuristic

We consider the logistics capacity planning problem arising in the context of supply-chain management. We address the tactical-planning problem of determining the quantity of capacity units, hereafter called bins, of different types to secure for the next period of activity, given the uncertainty on future needs in terms of demand for loads (items) to be moved or stored, and the availability an...

Multi-Modal Scheduled Service Network Design with Resource Management for Two-Tier City Logistics

Urban Freight Transport Demand Modelling: a State of the Art

The paper provides a review of freight transport demand models for applications in urban and metropolitan areas. The perspective adopted is the short-term one of public decision-makers involved in transport planning and traffic management. The paper recalls the general methodology to be used for assessing the city logistics scenario and the features of models in relation to the planning horizon...

An optimization model for management of empty containers in distribution network of a logistics company under uncertainty

In transportation via containers, unbalanced movement of loaded containers forces shipping companies to reposition empty containers. This study addresses the problem of empty container repositioning (ECR) in the distribution network of a European logistics company, where some restrictions impose decision making in an uncertain environment. The problem involves dispatching empty contain...
