Vehicle routing with private and shared delivery locations

2021

Abstract The rapid growth of e-commerce has led to an increase of home delivery requests. Providing efficient distribution systems for services on the last mile has become a challenging issue for logistics companies, where a trade-off between the classical approaches, attended home delivery (AHD) and usage of shared delivery locations (SDLs) has been identified. AHD provides a higher quality of service but implies very high costs for the company, while usage of SDL requires customers to perform the very last mile by themselves. For companies, this bears the risk of a decrease in the perceived service quality. However, due to consolidation effects, transportation costs can be considerably mi…

Understanding the Key Factors of Shared Mobility Services: Palermo as a Case Study

2020

The potential success of shared mobility services in the urban area strongly depends on careful tariff planning, adequate sizing of the fleet and efficient integrated public transport system, as well as on the application of policies in favor of sustainable modes of transport. The balance between earnings and expenses is not always an easy target for the companies in those cities where these services are not well-rooted in the citizens’ mobility habits. Often only large operators in the sector can continue to offer a service generating profit. However, several factors can determine the success or the failure of shared mobility services. The objective of this study is to identify, thanks to …

A multiple layered functional data model to support multiple representations and interoperability of GIS

2001

This paper presents a multi-layered functional data model to support multiple representation and information sharing among distributed spatial information systems. The key idea is that a geographical space (foe example an urban space) can be viewed as a set of abstract spatial functionalities on which different application classes can be derived to manipulate objects of the same geographical space and share the same abstract generic functionalities. The object classes define multiple views or representations of a domain. For example in urban management, transportation systems, water supply and sewage systems applications can share generic network functionalities defined by graph treversal o…

Charge loss correction in CZT pixel detectors at low and high fluxes: analysis of positive and negative pulses

2018

Charge losses are typical drawbacks in cadmium–zinc–telluride (CZT) pixel detectors. The effects of these phenomena are strongly related to the interaction point of the photons and are more severe for photon interactions at the inter-pixel gap and near the pixelated anode. In this work, we present some original techniques able to correct charge losses in pixelated CZT detectors at both low and high fluxes. The height, the shape and the arrival time of collected- and induced-charge pulses with both positive and negative polarities are analysed to recover charge losses after the application of charge sharing addition (CSA). Sub-millimetre CZT pixel detectors, fabricated by different manufactu…

Connection between Design and Nature Reflections and Projects for the future of the Planet

2022

Humanity’s delayed reaction to the consequences of the climate crisis is the result of multiple interests and strategies caused by denialist policies and piloted information. It is also true, however, that there is a strictly cultural responsibility, in the form of a lack of dialogue between sources of knowledge. Restoring the balance between humanity and nature is the most important issue that contemporary design must address. Design has the task of highlighting objects and strategies in re-establishing the relationship between Man and the context in which he lives by re-integrating the social and natural ecosystems. In this context, thanks to the evolution of natural sciences and technolo…

I project. Methodologies, strategies and results

2019

Every year since 2010 - between the end of August and the beginning of September - OC OPEN CITY International Summer School means a fantastic collective experience. Students (the main characters), professors, lecturers and tutors are involved in a great adventure where architecture and design build a common ground. Landscape 4.0 - the title of OC 9th edition - presents the results of the edition of the 2018. Landscape 4.0 is the landscape of sharing: sharing people, sharing ideas, sharing cultures, sharing experiences. "I Project" is a proposal of Landscape 4.0 for an abandoned military area in Piacenza (Caserma Pontieri). Landscape architecture has been considered as a plot of relations to…

La sharing mobility è un approccio alla mobilità sostenibile dal punto di vista dell’impatto ambientale? Alcune considerazioni basate su un’analisi e…

2020

L'influenza della sharing mobility sulla sostenibilità ambientale non è stata ancora pienamente compresa. Da un lato la sharing mobility consente ai consumatori di assumere comportamenti che portano ad una riduzione delle emissioni di CO2 grazie, per esempio, alla minore produzione di automobili (riduzione dell’acquisto di auto) e alla riduzione dei chilometri percorsi dalle auto (condivisione della corsa e maggiore tasso di occupanti per veicolo). D'altra parte, l'implementazione della sharing mobility porta ad effettuare un numero maggiore di viaggi in automobile. Infatti, un certo numero di chilometri che vengono percorsi oggi dalle auto condivise, erano percorsi prima con mezzi di trasp…

Enabling peer-to-peer User-Preference-Aware Energy Sharing Through Reinforcement Learning

2020

Renewable, heterogeneous and distributed energy resources are the future of power systems, as envisioned by the recent paradigm of Virtual Power Plants (VPPs). Residential electricity generation, e.g., through photovoltaic panels, plays a fundamental role in this paradigm, where users are able to participate in an energy sharing system and exchange energy resources among each other. In this work, we study energy sharing systems and, differently from previous approaches, we consider realistic user behaviors by taking into account the user preferences and level of engagement in the energy trades. We formulate the problem of matching energy resources while contemplating the user behavior as a …
