Within the data envelopment analysis context, problems of discrimination between efficient and inefficient decision-making units often arise, particularly if there are a relatively large number of variables with respect to observations. This paper applies Monte-Carlo simulation to generalize and compare two discrimination-improving methods; principal(More)
This paper presents a framework to analyze global alliances and mergers in the airline industry under competition. The framework can help airlines identify partners and network structures, and help governments predict changes in social welfare before accepting or rejecting proposed mergers or alliances. The research combines profit-maximizing objectives to(More)
T he aim of this paper is to present a model structure that analyzes the hub-spoke network design issue within a competitive framework. Under deregulation, airlines have developed hub-and-spoke networks, enabling them to increase frequency by aggregating demand and to prevent entry into the marketplace by reducing airfares. While liberalization in the(More)
This research investigates the traffic police routine patrol vehicle (RPV) assignment problem on an interurban road network through a series of integer linear programs. The traffic police RPV's main task, like other emergency services, is to handle calls-for-service. Emergency services allocation models are generally based on the shortest path algorithm(More)
Benchmarking airports is currently popular both in the academic literature and in practice but has proved rather problematic due to the heterogeneity inherent in any reasonably sized dataset. Most studies either treat the airport production technology as a black box, or separate the terminal and airside activities, assessing them individually. In this(More)
Small and regional airports frequently suffer from limited traffic given minimum fixed infrastructure requirements and insufficient revenues to cover their costs. The question is whether such airports could be structured, managed and possibly financially supported in order to survive efficiently. Efficient operations contribute to decreasing the financial(More)
Accounting for desire for variety within the consumer demand function, a two stage hybrid competitive-cooperative game analyzes di¤erentiated oligopolies under varying market structures from competition through pooling contracts up to antitrust immune alliances. From a managerial perspective, pooling agreements not only bene…t …rms by better matching supply(More)
