Air ticket sales revenue is an important source of revenue for travel agencies, and if future air ticket sales revenue can be accurately forecast, travel agencies will be able to advance procurement to achieve a sufficient amount of cost-effective tickets. Therefore, this study applied the Artificial Neural Network (ANN) and Genetic Algorithms (GA) to establish a prediction model of travel agen...

The Kassa module is part of a ticket ordering system developed by a company. It is a front-end running on client machines used by ticket sales clerks in ticket agencies and box offices. The Kassa module is operational and several of the company’s customers use it. The module is written in Java and about ten years old. The architecture of the Kassa module has become deprecated and is hard to mai...

Several authors have argued that because modern computing and communications technologies reduce buyer search costs and other market inefficiencies, there should be intense price competition between sellers in electronic markets. This paper examines this prediction using data on the airline ticket offerings of online travel agents (OTA). We find that different OTAs offer tickets with substantia...

This memo documents a method for a Kerberos Key Distribution Center (KDC) to respond to client requests for Kerberos tickets when the client does not have detailed configuration information on the realms of users or services. The KDC will handle requests for principals in other realms by returning either a referral error or a cross-realm Ticket-Granting Ticket (TGT) to another realm on the refe...

Replay attack and password attacks are serious issues in the Kerberos authentication protocol. Many ideas have been proposed to prevent these attacks but they increase complexity of the total Kerberos environment. In this paper we present an improved method which prevents replay attacks and password attacks by using Triple password scheme. Three passwords are stored on Authentication Server and...

The start of the European Electronic Toll Service (EETS) appears far from being thoroughly realized, because of the unclear definition of a business model especially from the point of view of the EETS Providers. Toll Chargers started to approach EETS at a greater speed, as they shall accept any possible Provider from October 2012. The EETS Directive is one of the factors affecting the next arch...

U.S. airlines achieved a startling turnaround in 2009. Profits rose to $2.3 billion after a loss of $3.3 billion the year before. Also during 2009, the airlines collected $2.7 billion in baggage fees (U.S. Bureau of Transportation Statistics 2010). In other words, by charging separately for a service once associated with the price of a ticket, the airlines turned a potential loss into a profit....

In this paper, I analyze the setting of ticket prices when teams receive subsidization from the public. I model teams as entertainment providers, where entertainment is generated by selling wins and amenities. I argue that subsidization of teams generally comes from subsidizing the amenities in and surrounding the teams’ stadiums. Subsidization of the amenities lowers the marginal cost of provi...
