LA COSTA, LA CITTÀ E IL PORTO. IL COORDINAMENTO TRA PIANIFICAZIONE URBANISTICA E PORTUALE NEI PORTI DI INTERESSE NAZIONALE E INTERNAZIONALE

2013

Lo scrittto, ricostruita la storia del rapporto tra la potestà urbanistica comunale e l'amministrazione del porto, si occupa di individuare gli attuali profili di conflitto tra interessi della città e interessi dell'autorità portuale, concentrandosi sulla fattispecie degli scali di rilevanza internazionale o nazionale. Da tale prospettiva, l'articolo individua le soluzioni che sul piano procedimentale sono in grado di risolvere il problema della difficile adozione, presso la gran maggioranza degli scali del paese, del piano regolatore portuale introdotto dall'art. 5 della legge n. 84 del 1994.

Modelling sediment delivery processes by a stream tube approach

1999

Abstract The sediment delivery processes due to the travel along a hydraulic path having an uniform slope and to the concave shape of the path are modelled. In particular, using a power equation for modelling the slope profile and RUSLE with two different expressions of the topographic factors, a criterion to define the erosion active slope length, i.e. the slope length in which no deposition processes occur, is initially proposed. Then, the RUSLE equation is adapted to concave profiles by a correction factor of the topographic factors depending on slope curvature. Finally, the deduced relationships (equations (19) and (27)) for correcting the topographic factors for a concave slope are exp…

Effects of distance and scale dependence in geographical models of cities and territories

2019

International audience; This third chapter questions the essential role of distance and scale dependence in models to analyzing the spatial configuration of human settlements and activities, as well as the processes that lead to their evolution, with reference to urban or regional study areas. The subject of study therefore concerns both the form of human settlements and the actions of people (individuals, groups) in their territory (or territories). A human settlement consists of the materialization in space-the physical inscription-of one or more human activities. It is characterized by a certain degree of sustainability. It can be a group of a few buildings or a larger group of thousands…

Large‐scale set partitioning problems: Some real‐world instances hide a beneficial structure

2006

In this paper we consider large‐scale set partitioning problems. Our main purpose is to show that real‐world set partitioning problems originating from the container‐trucking industry are easier to tackle in respect to general ones. We show such different behavior through computational experiments: in particular, we have applied both a heuristic algorithm and some exact solution approaches to real‐world instances as well as to benchmark instances from Beasley OR‐library. Moreover, in order to gain an insight into the structure of the real‐world instances, we have performed and evaluated various instance perturbations.

Maritime Supply Chain Security: A critical review

2013

The importance of container security for international trade is well established and has been the subject of recent research in the follow up of the implementation of global security initiatives and the imperative of avoiding supply chain disruptions and reduce vulnerability. This article provides a review of the emerging literature on container security specifically in its interface with global logistics systems. The paper highlights the topics that have emerged as well-established research areas and indicates in what areas scholarly attention is most needed.

Solving a large multicontainer loading problem in the car manufacturing industry

2017

Abstract Renault, a large car manufacturer with factories all over the world, has a production system in which not every factory produces all the parts required to assemble a vehicle. Every day, large quantities of car parts are sent from one factory to another, defining very large truck/container transportation problems. The main challenge faced by the Renault logistics platforms is to load the items into trucks and containers as efficiently as possible so as to minimize the number of vehicles sent. Therefore, the problem to be solved is a multicontainer loading problem in which, besides the usual geometric constraints preventing items from overlapping and exceeding the dimensions of the c…

Mathematical models for multicontainer loading problems

2017

Abstract This paper deals with the problem of a distribution company that has to serve its customers by putting first the products on pallets and then loading the pallets onto trucks. We approach the problem by developing and solving integer linear models. We start with basic models, that include the essential features of the problem, such as respecting the dimensions of the truck, and not exceeding the total weight capacity and the maximum weigh capacity on each axle. Then, we add progressively new conditions to consider the weight and volume of pallet bases and to include other desirable features for the solutions to be useful in practice, such as the position of the center of gravity and…

Mathematical models for Multi Container Loading Problems with practical constraints

2019

Abstract We address the multi container loading problem of a company that serves its customers’ orders by building pallets with the required products and loading them into trucks. The problem is solved by using integer linear models. To be useful in practice, our models consider three types of constraints: geometric constraints, so that pallets lie completely inside the trucks and do not overlap; weight constraints, defining the maximum weights supported by a truck and by each axle, as well as the position of the centre of gravity of the cargo; and dynamic stability constraints. These last constraints forbid empty spaces between pallets to avoid cargo displacement when the truck is moving, …
