Operations research in the management of the airlines

This paper is intended to present an introduction to the use of operations research in the international airline industry, and to demonstrate the scope and significance of the airline OR activities. First, the special reasons for the viability and spread of airline OR are discussed. Then a functional framework for an airline is outlined, to be used in analyzing the problems of an airline and relating the OR work to it. Four major applications are described, corresponding to four major components of the framework. These applications are: schedule development, overbooking control, crew scheduling and engine management, respectively. In each case we describe the problem and its significance, indicate the types of solution techniques which have been developed, and assess the implemented solutions. The paper concludes with comments on the current state-of-the-art and the future of airline OR. A detailed bibliography is given.Both of the authors have been operations research directors in major airlines and more recently have focused their attention upon the industry as academic researchers. This background has provided us with an unusual opportunity to analyze the role of OR in the airlines, and our paper seeks to share with the reader some of the insights we have gained thereby.     

股东参与治理的私人收益和社会收益的实证研究

本文探讨了股东参与治理所带来的私人收益、特定股权结构的社会收益以及股权集中成本三者之间的关系。我们分析的结果表明,当股东与经理人员之间的利益冲突水平较高、其它治理机制的作用较弱时,股权集中(股东参与治理的积极性较高)可以创造大量的社会收益;反之,股权的集中与分散程度(股东参与治理的积极性较低)对社会收益的影响不明显。本文的研究结论为我国股东参与治理及股权结构改革提供了重要启示。     

Bangladeshi women migrants amidst the COVID-19 pandemic: Revisiting globalization,dependency and gendered precarity in South–South labour migration

The COVID-19 pandemic has triggered unprecedented societal disruption and disproportionately affected global mobility dynamics. Within such a troubled and intensifying crisis, the intersection of migration and gender is even more unsettling. Since the pandemic outbreak, Bangladesh witnessed a colossal crisis among millions of Bangladeshi migrants working overseas—a considerable section of them are women. By highlighting the plight of the Bangladeshi women migrants in the Gulf Cooperation Council (GCC) countries, this study expands the emerging literature that addresses the nexus among migration, pandemic fallout and gendered labour. Redrawing our understanding of globalization from below, the study attempts to further advance the theoretical perspectives on the predicaments of globalization and gendered precarity in contract labour migration. The study argues that the focus on the power asymmetry between the host and sending countries remains too limited to provide a comprehensive understanding of how inequalities are reproduced and transformed. Instead, it suggests that the challenges and disadvantages women migrants endure are embedded in the asymmetries of deep-rooted economic and social structures in tandem with the systemic practice of otherness and exclusion.
