The Linkages Among Market Structure, Market Conduct, And Service Quality: Analysis Of The U.S. Domestic Airline Industry, Amirhossein Alamdar Yazdi

Doctoral Dissertations

As supported by the dynamic structure-conduct-performance (S-C-P) paradigm, market structure affects conduct, and conduct determines firms’ performance (Mckinsey & Company Quarterly, 2008). Several researchers have looked at the S-C-P relationship with focus on price. Boreinstein, 1990; Beutel and McBride, 1992; Kim and Singal, 1993; Morrison, 1996; Veldhuis, 2005; Peters, 2006; Zhang and Round, 2009 looked at the effect of airline mergers on fares; some others have looked at the linkage between the imposition of fees and stock values (Barone, et al., 2012), ticket prices (Henrickson & Scott, 2012; Brueckner, et al., 2015); and some examine the effects of low-cost carriers …

Game Theory For Security Investments In Cyber And Supply Chain Networks, Shivani Shukla

Doctoral Dissertations

In a constantly and intricately connected world that is going digital, cybersecurity is imperative to not just the success but also the survival of a business. The ubiquitous digital transformation is fueled by a convulsive growth of devices and data that are leading important innovations in the domain of cyber-physical systems. However, this growth has also enabled internal and external threats to skyrocket, depicting the inherent dichotomy. With an evolving threat landscape, a perpetrator has to be successful once, while the defenders have to continually succeed in fending-off attacks to protect critical infrastructure and digital assets. Businesses are facing a …


Retail Analytics And Optimization For Store-Wide Shelf-Space Management, Tulay Flamand Nov 2016

Retail Analytics And Optimization For Store-Wide Shelf-Space Management, Tulay Flamand

Doctoral Dissertations

A major constituent of modern-time economies, retailing is a vibrant business sector that is marked by high competition, tight profit margins, novel business strategies in online and in-store environments, and demanding consumers. Driven by massive volumes of point-of-sale data, retail analytics has become instrumental for unveiling better managerial practices. Our research falls under the umbrella of retail shelf space management. In self-service outlets, shelf space constitutes a scarce resource and its management is central to ensuring an attractive shopping experience and a profitable business. We investigate how, under a given store layout, the allocation of product categories can be optimized …


Service Improvement And Cost Reduction For Airlines: Optimal Policies For Managing Arrival And Departure Operations Under Uncertainty, Heng Chen Nov 2016

Service Improvement And Cost Reduction For Airlines: Optimal Policies For Managing Arrival And Departure Operations Under Uncertainty, Heng Chen

Doctoral Dissertations

Annual U.S. air travel demand has been growing steadily by 4-5% over the last decade, and it is estimated that the demand will nearly double in the next twenty years. It has also been estimated by the International Civil Aviation Organization that global demand for commercial aircraft will increase at an average annual rate of 4.1% by 2034 (IATA, 2014). However, airport expansions and aviation infrastructure upgrades have not kept pace with the increase in air traffic demand, as only 3% of all the new airport projects around the world are planned in the U.S. (CAPA, 2015). Thus, the operation …


Network Game Theory Models Of Services And Quality Competition With Applications To Future Internet Architectures And Supply Chains, Sara Saberi Nov 2016

Network Game Theory Models Of Services And Quality Competition With Applications To Future Internet Architectures And Supply Chains, Sara Saberi

Doctoral Dissertations

The Internet has transformed the way in which we conduct business and perform economic and financial transactions. One key challenge of the Internet is the inefficiency of the mechanisms by which technology is deployed and the business and economic models surrounding these processes (Wolf et al. (2014)). Equilibrium models for the Internet generally assume basic economic relationships. However, in new paradigms for the Internet and in supply chain networks, price is not the only factor; quality of service (QoS) is also of increasing importance. Supply chains networks, which give us the means to manufacture products and deliver them to points …

Quality Competition In Supply Chain Networks With Applications To Information Asymmetry, Product Differentiation, Outsourcing, And Supplier Selection, Dong Li

Doctoral Dissertations

The quality of the products produced and delivered in supply chain networks is essential for consumers' safety, well-being, and benefits, and for firms' profitability and reputation. However, because of the complexity of today's large-scale highly globalized supply chain networks, along with issues such as the growth in outsourcing and in global procurement, as well as the information asymmetry associated with quality, supply chain networks are more exposed to both domestic and international quality failures. In this dissertation, I contribute to the equilibrium and dynamic modeling and analysis of quality competition in supply chain networks under scenarios of information asymmetry, product …
