Adaptive Stochastic Airline Seat Inventory Control under Parametric Uncertainty

2013

Airline seat inventory control is a very profitable tool in the airline industry. The problem of adaptive stochastic airline seat inventory control lies at the heart of airline revenue management. This problem concerns the allocation of the finite seat inventory to the stochastic customer demand that occurs over time before the flight is scheduled to depart. The objective is to find the right combination of customers of various fare classes on the flight such that revenue is maximized. In this paper, the static and dynamic policies of stochastic airline seat inventory control (airline booking) are developed under parametric uncertainty of underlying models, which are not necessarily alterna…

Improvement of Inventory Control under Parametric Uncertainty and Constraints

2011

The aim of the present paper is to show how the statistical inference equivalence principle (SIEP), the idea of which belongs to the authors, may be employed in the particular case of finding the effective statistical decisions for the multi-product inventory problems with constraints. To our knowledge, no analytical or efficient numerical method for finding the optimal policies under parametric uncertainty for the multi-product inventory problems with constraints has been reported in the literature. Using the (equivalent) predictive distributions, this paper represents an extension of analytical results obtained for unconstrained optimization under parametric uncertainty to the case of con…

La compatibilità della finanza islamica con l'ordinamento italiano: commento al progetto di legge del 2017

2019

In 2017 a draft law on shari’ah compliant contracts was presented to the Chamber of Deputies. According to Profit-Loss Sharing principle, which is at the basis of Islamic contracts, in addition to providing credit the lender shares debtor’s business risk, and the ban on ribà, associated with the prohibition of interest and usury. There is a problem of compatibility between the Islamic finance approach and the Western finance model, only partially addressed by the draft law. However, Islamic contracts pursue an interest worthy of protection on the basis of article n. 1322, 2nd paragraph, of the Civil Code, and the transition to the universal bank model makes it possible to bring the Islamic …

Optimal control of quantum superpositions in a bosonic Josephson junction

2012

We show how to optimally control the creation of quantum superpositions in a bosonic Josephson junction within the two-site Bose-Hubbard model framework. Both geometric and purely numerical optimal control approaches are used, the former providing a generalization of the proposal of Micheli et al [Phys. Rev. A 67, 013607 (2003)]. While this method is shown not to lead to significant improvements in terms of time of formation and fidelity of the superposition, a numerical optimal control approach appears more promising, as it allows to create an almost perfect superposition, within a time short compared to other existing protocols. We analyze the robustness of the optimal solution against at…

OS ECJ-TF 3/2017 on the Decision of the Court of Justice of the European Union of 16 May 2017 in Berlioz Investment Fund SA (Case C-682/15), Concerni…

2018

This article examines the decision of the Grand Chamber of the Court of Justice of the European Union (ECJ) in Berlioz Investment Fund SA (Case C-682/15) delivered on 16 May 2017, following the Opinion of Advocate General Wathelet of 10 January 2017. The case concerned the levying of tax penalties in circumstances in which a third party partially refused to provide the Luxembourg tax authorities with information requested, by way of mutual assistance under the Mutual Assistance Directive (2011/16), by the French tax authorities. Having clarified that when exchanging information by way of mutual assistance under an EU directive, EU Member States are implementing EU Law, the Grand Chamber con…

Has Pandora's Box Been Closed? The Decisions on the Legality of Use of Force Cases about the Status of the Federal Republic of Yugoslavia (Serbia and…

2006

In its judgments on the preliminary objections in the Legality of Use of Force cases, the Court held that the FRY was not a UN member in the period between 1992 and 2000. This finding is controversial, at odds with previous decisions of the Court, and has indeed attracted criticism from various judges. This article proposes a different construction of the question of the FRY's membership within the UN and reviews arguments that allow doubts to be cast on the reasoning of the Court. Because of the link between UN membership and the FRY's participation in the Genocide Convention, the Court's finding in the Legality of Use of Force cases may have some implications for two sets of proceedings s…

Aims To report corneal topometric and aberrometric values in mucopolysaccharidosis (MPS) and to investigate their correlation with biomechanical corneal parameters. Methods One randomly chosen eye of 20 MPS patients with no to moderate corneal clouding and one eye of 23 healthy controls with comparable age were prospectively included into this study. Corneal surface regularity was assessed by index of surface variance (ISV), -vertical asymmetry (IVA), -height asymmetry (IHA), -height decentration (IHD); keratoconus index (KI), central keratoconus index (CKI) and Zernike indices of anterior and posterior corneal surface using Scheimpflug imaging (Pentacam). Corneal resistance factor (CRF) an…
