In particular, the problem has been tackled considering the requirements indicated for the Italian case related to the reorganisation of pre-primary, primary and secondary schools in integrated institutions managed in a centralised way. In order to solve the problem, two versions of a location model are proposed. The application to a real case study shows how the model can be used as a viable decision support system.

In Italy this reform process provided significant transformations of the national university system and of the students' mobility with a decentralization process characterized by an increase of university enrolment and of academic sites. In this paper we investigate the mobility of Italian university students using an adaptation of gravity distribution models. Results provided by the model are compared with official ministerial data, showing that the model can efficiently describe the students' mobility phenomenon.

An increasing number of researches have been devoted to the development of different kind of methodologies to cope with this problem. Nevertheless, while the number of applications is growing, there is little empirical evidence of the practical usefulness of such tools with a dichotomy between theoretical approaches and empirical applications. Considering this evidence, the goal of this paper is to contribute to understand the above dichotomy by implementing, in a corporate environment, a model for supplier evaluation based on the Analytical Hierarchical Process (AHP), one of the most prominent methodologies used to address the problem. The analysis of the implementation process of the methodology allows the identification of strengths and weaknesses of using formalized supplier selection models to tackle the supplier evaluation problem, also highlighting potential barriers preventing firms to adopt such methods. Relevant issues arising from the application and managerial implications for both customer and suppliers are discussed.

The aim of this paper is twofold. First, a careful scrutiny of the papers appearing in international scientific journals in recent years on the greener supplier selection problem is provided, highlighting utilised methodologies and current issues; second, a verification of the penetration of environmental and green criteria for the supplier selection in corporate practice is performed, using a questionnaire survey targeting the top 100 manufacturing companies operating in South Yorkshire (UK) and two in-depth interviews at large MNE firms operating in complex industries. Results show that, while interest in the literature is growing, there is little empirical evidence of the transfer of these applications into the real world, highlighting a persistent dichotomy between theory and practice. The reasons for this dichotomy are also investigated.

The potential of biofuels contributing to the UK emission reduction targets in the formulated UK ... more The potential of biofuels contributing to the UK emission reduction targets in the formulated UK Low Carbon Transition Plan (LCTP) and the UK's obligation in the wider EU emissions reduction targets are assessed using four scenarios. The scenarios were evaluated using hybrid lifecycle assessment developed in a multi-regional input-output (MRIO) framework. In the hybrid MRIO LCA framework, technology-specific processes in the biofuels and fossil fuels LCA systems are integrated into a generalised 2-region (UK and Rest of the World) environmental-economic input-output framework in order to account for economy-wide indirect GHG emissions in the biofuels and fossil fuels LCA systems in addition to other indirect impacts such as indirect land use change. The lifecycle greenhouse gas emissions of biodiesel (soybean, palm, rape, waste cooking oil) and bio-ethanol (sugarcane, sugarbeet, corn) were assessed and compared to fossil fuel (diesel and petrol) baseline. From one of the scenarios, biodiesel production from waste cooking oil and bioethanol from sugarbeet offer the biggest potential for emissions savings relative to fossil fuel equivalent and offering a maximum emission savings of 4.1% observed with a biofuel market share of 10% reached in 2020. It was also established that under current biofuel feedstock mix, to achieve the 6% emissions saving primarily from biofuels as proposed in the LCTP, 23.8% of the transport fuels market would be required to be held by biofuels by 2020.

The aim of this paper is to highlight, once more, the powerfulness of these seminal contributions by showing how the mathematical formulation of the Capacitated Lot Sizing Problem can be easily adapted to solve some further practical logistics applications (mainly arising in the field of coordination of transportation services) not strictly related to manufacturing and production environment. Mathematical formulations and computational experiences will be provided to support these statements.

In this article, the authors analyze shortcomings of extant indexes. Using multivariate analysis tools, they show that in the definition of composite indexes it is possible to individuate a limited set of more influencing and significant variables. This finding suggests the possibility of replacing some redundant variables with other dimensions that include other aspects of the digital divide that are not considered in extant measures.

As many conflicting factors should be taken into account in the analysis, the problem can be tackled using multi-criteria models and methods. In this work a careful scrutiny of the papers appeared on international scientific journals in the recent years about SSP is provided. The survey highlights that the most used methodology is the Analytical Hierarchy Process (AHP). Thus, an overview view of the current proposals based on AHP and its variants to cope with the SSP is provided. Crucial aspects which arise when the methodology is actually applied in real cases are identified and discussed.

The aim is to decide the optimal number of check-in gates to open for departing flights, in such a way to balance the operative costs of the service and the passenger waiting time at the terminal. We propose new models for this problem, which presents strong similarities with some well known combinatorial optimization models. We show the complexity of the models and computational results based on a real case study.
