Control points deployment in an Intelligent Transportation System for monitoring inter-urban network roadway

2022

Abstract The constant evolution of transportation systems and traffic in developing countries is nowadays confronted with a problem of road safety and therefore of a high accident rate, especially in the context of inter-urban road transport. In this work, we propose a communication architecture for an Intelligent Transport System (ITS) to provide surveillance in an inter-urban transport network in the context of developing countries. We introduce two types of control points: Relay Control Points (RCP) and Treatment Control Points (TrCP). We also designed two multi-objective models for the deployment of these points. In order to ensure good coverage, to minimize the cost of installation and…

eHealth-Extended Care Coordination: Development of a Collaborative System for Inter-municipal Dementia Teams: A Research Project with a User-Centered…

2015

- In Norway, a health reform was recently adopted to improve continuity of care. Services that were carried out in hospitals were transferred to municipalities. Small and medium size municipalities have established inter-municipal cooperation to provide specialized services across borders. The research project eHealth-extended Care Coordination studied the inter-municipal cooperation for assessment of dementia, identifying a need for improved communication and coordination. This paper presents the development process of a collaborative information system for dementia assessment using a user-centered design approach. Mixed methods, such as observations, semi-structured interviews and questio…

The CFO’s Information Challenge in Managing Macroeconomic Risk

2010

In this paper we examine the role of the CFO in setting risk management strategy with respect to macroeconomic risk, in particular, and we consider the information requirements for setting a strategy that is consistent with corporate objectives. We argue that macroeconomic risk management requires a broad approach encompassing financial, operational and strategic considerations. Furthermore, several interdependent sources of risk in the macroeconomic environment must be taken into account. Once this interdependence among, for example, exchange rates, interest rates and inflation are taken into account macroeconomic risk management can be considered a relatively self-contained aspect of Inte…

Heuristics for a Real-World Mail Delivery Problem

2011

We are solving a mail delivery problem by combining exact and heuristic methods. The problem is a tactical routing problem as routes for all postpersons have to be planned in advance for a period of several months. As for many other routing problems, the task is to construct a set of feasible routes serving each customer exactly once at minimum cost. Four different modes (car, moped, bicycle, and walking) are available, but not all customers are accessible by all modes. Thus, the problem is characterized by three interdependent decisions: the clustering of customers into districts, the choice of a mode for each district, and the routing of the postperson through its district. We present a t…

Job seeker's spatial equilibrium in a fuzzy mathematical framework

1990

This paper incorporates complex behavior in a job seeking strategy model. Since the state of information is imperfect, a job seeker faces an imprecise labor market. His behavior is fuzzy and variable. It is shown how this complex behavior can be described by fuzzy subsets theory and bifurcation analysis. The latter examines the discontinuous phenomena. Then it is proved that a job seeker’s fuzzy equilibrium with a spatial constraint exists.

New development opportunities for the craft brewing segment: the case study of a micro-malthouse

2017

In Italy in the past few years, the number of small breweries penetrating the craft beer sector has grown exponentially. Craft producers intend to give a strong added value and a local character to their production in different ways. One of these is the use of malt derived from small batches of local cereals and pseudo cereals. The aim of this study is the assessment of investment profitability, through a cost-benefit analysis (CBA), for a compact and a modular micro-malting plant in Sicily (Southern Italy). The CBA for a micro-malthouse was carried out considering both installation and operating costs. Net present value (NPV), discounted benefit-cost ratio (DBCR) and internal rate of retur…

Impact of covid-19 in gynecologic oncology: A nationwide italian survey of the sigo and mito groups

2020

Objective Coronavirus disease 2019 (COVID-19) has caused rapid and drastic changes in cancer management. The Italian Society of Gynecology and Obstetrics (SIGO), and the Multicenter Italian Trials in Ovarian cancer and gynecologic malignancies (MITO) promoted a national survey aiming to evaluate the impact of COVID-19 on clinical activity of gynecologist oncologists and to assess the implementation of containment measures against COVID-19 diffusion. Methods The survey consisted of a self-administered, anonymous, online questionnaire. The survey was sent via email to all the members of the SIGO, and MITO groups on April 7, 2020, and was closed on April 20, 2020. Results Overall, 604 particip…

Pricing and infrastructure fees in shaping cooperation in a model of high-speed rail and airline competition

2020

Abstract This paper studies the effects of cooperation in a hub-and-spoke network with high-speed rail and airline competition. The distinctive elements of our analysis are the consideration of: (i) per-passenger airport and rail infrastructure fees; (ii) mixed bundling pricing by partners, and (iii) an airline duopoly in the international market. We show that partners fix the cheapest bundle price of the combined trip, that non-allied operators respond by decreasing the prices per link, and that connecting traffic increases. Per-passenger fees significantly affect the price differences following cooperation. An empirical application confirms that it is privately profitable and that welfare…

Dinamiche competitive dei principali prodotti ittici in Italia: possibili strategie di intervento

2011

Over the last few years, the Italian fishery sector has showed a tendential reduction in the economic performance because of the contraction of the value of the product, as a result of the fall in the catches and in the production average prices of the main species, and of the growing operational costs. Therefore, the contraction of the National supply is balanced by the imports which, in terms of value in the reference period tested in the current study (2003/04 – 2007/08) have grown, causing a further burdening in the absolute value of the Italian trade balance. The outlined background is made further worse by the slowdown, in few years, in the rise in the fishery products consumptions, d…
