In this paper we focus our attention on the operational decision problems related to the seaside area of maritime container terminals. In particular, we face the Quay Crane Assignment Problem (QCAP) and Quay Crane Scheduling Problem (QCSP) with an integrated simulation-optimization approach. A 0/1 MIP model is developed in order to...

In this paper we present a discrete event simulation model to approach the decision problems arising from an expansion plan of a marine container terminal. In particular the preliminary study herein presented starts from a collaboration with the Southern European Container Hub (SECH) sited in the Port of Genoa, Italy. The planned expansion will...

In this paper the train load planning problem arising in a seaport container terminal is considered. This problem consists in determining the optimal assignment of containers to wagon slots in order to maximize the train utilization and, at the same time, to minimize unproductive operations in the terminal. Different solution approaches based...

The present paper deals with the problem of locating hubs for freight mobility in urban and suburban areas. In particular, we present a heuristic method that combines aspects coming from both classical simple plant location problems and shortest path ones on multimodal graphs. In the first phase of the proposed heuristics, we identify those...

In this paper we deal with a capacitated hub location problem arising in a freight logistics context; in particular, we have the need of locating logistics platforms for containers travelling via road and rail. The problem is modelled on a weighed multimodal network. We give a mixed integer linear programming model for the problem, having the...

We study some complex distribution network design problems, which involve facility location, warehousing, transportation and inventory decisions. Several realistic scenarios are investigated. Two kinds of mathematical programming formulations are proposed for all the introduced problems, together with a proof of their correctness. Some...

In this work, we deal with a food distribution problem that can be considered as a generalization of the asymmetric capacitated vehicle routing problem with split delivery. In particular, we are involved with a real application related to an Italian company that holds food markets along the national highway network and has to determine the...

In this paper we deal with the problem of finding optimal routes in multimodal networks. Since modal change nodes play a relevant role in the choice of origin – destination paths, and consequently in the computation of multimodal shortest paths, we evaluate the performance of such nodes with the aim of increasing their attractivity. We propose...
