An Airline Seat Management Model for a Single Leg Route When Lower Fare Classes Book First

Abstract: It is common practice for airlines to charge several different fares for a common pool of seats. This paper presents a model that has been used to address the problem of when to refuse booking requests for a given fare level to save the seat for a potential request at a higher fare level. This model assumes that lower fare passengers book before higher fare passengers book. This occurs quite frequently in practice, where lower fare passengers are usually vacationers and higher fare passengers are usually business travelers. In fact, many airlines mandate this practice by imposing advance booking requirements on lower fare classes to prevent business travelers from using them. We present an algorithm that finds a seat management policy that maximizes mean revenue by establishing a critical value for each fare class. Booking requests for a particular fare level are accepted if the number of empty seats is strictly greater than its critical value and rejected otherwise. This critical value is a decreasing function of the fare price and is equal to zero for the class with the highest fare.

Pore Space Partition by Symmetry-Matching Regulated Ligand Insertion and Dramatic Tuning on Carbon Dioxide Uptake

Abstract: Metal–organic frameworks (MOFs) with the highest CO2 uptake capacity are usually those equipped with open metal sites. Here we seek alternative strategies and mechanisms for developing high-performance CO2 adsorbents. We demonstrate that through a ligand insertion pore space partition strategy, we can create crystalline porous materials (CPMs) with superior CO2 uptake capacity. Specifically, a new material, CPM-33b-Ni without any open metal sites, exhibits the CO2 uptake capacity comparable to MOF-74 with the same metal (Ni) at 298 K and 1 bar.

Caring for High-Need, High-Cost Patients—An Urgent Priority

Abstract: Five foundations aim to improve care for high-need, high-cost patients by building U.S. capabilities in three vital areas: clarifying the needs of such patients, elucidating the best ways of caring for them, and assisting with the spread of proven approaches.

Marketing on the internet - who can benefit from an online marketing approach

Abstract: The research builds upon the literature in electronic commerce and past research in marketing with the objective of understanding factors that impact a product's adaptability to online marketing. A review of marketing channel choice literature reveals a set of factors and channel choice functions that are considered important in making channel decisions. Using this as a basis, four major channel functions, namely, product customization, availability, logistics, and transaction complexity are considered relevant in understanding the implications for Internet marketing. By building upon previous research in the area of channel selection, we provide a means of classifying Internet marketing initiatives based on product characteristics. The classification scheme based on product characteristics can help analyze the significance of each factor on the success of a firm's online marketing approach. Further, the classification scheme is used to discuss decision support implications.
