A New Way to Improve Logistics Efficiency and Aircraft-Onground Recovery

The objective of this project was to bring more efficiency to logistics, improving time of Aircraft-on-Ground (AOG) recovery and developing possible saving for airlines operations. There proposed goal was to develop a system that would allow airlines to easily visualize an available space at the aircraft cargo bay on a desired flight and book its company materials (COMAT) on it, still respecting all appropriate regulation and the final availability of space. This project was inspired by an existing system called MyIDTravel that allows jointed airline’s personnel to buy available tickets with low fares. The objective was to develop something similar for COMAT. The personnel responsible for logistics at jointed airlines would be able to check available cargo bay spaces on the desired flights and book COMAT transportation paying regular prices but having priority over regular cargo. This would enhance the utilization of empty space and optimize the transportation of required material to restore or maintain the airlines operation

A Dynamic Programming Model to Optimize the Capacity Control with the Priority of Air Cargo

This paper concentrates on the problem of the air cargo space management strategy with a comprehensive, abstract and simplified way, on the basis of the actual characteristics of transport demand in China's air cargo market. We focus on the urgent transportation of goods and general cargo transport whose time requirements are different. The paper first proposes a single-leg cargo space management dynamic programming model according to the different time limit of different kinds of goods, and then the two dimensional single-leg air cargo problem is transformed into one dimensional two-leg airline network problem. After that, we use the expanded method of dynamic programming decomposition to solve the model. A numerical example is solved and simulated to verify the effectiveness of the program

Dynamic Capacity Control in Air Cargo Revenue Management

This book studies air cargo capacity control problems. The focus is on analyzing decision models with intuitive optimal decisions as well as on developing efficient heuristics and bounds. Three different models are studied: First, a model for steering the availability of cargo space on single legs. Second, a model that simultaneously optimizes the availability of both seats and cargo capacity. Third, a decision model that controls the availability of cargo capacity on a network of flights

INTERNATIONAL PRICE TRANSMISSION IN THE U.S.-JAPAN SOFTWOOD TRADE

This article explores the supposition that international price margins in the U.S. Pacific Northwest-Japan softwood trade are influenced by nontariff trade barriers and inelastic supplies of international transportation services. Furthermore, it pursues the hypothesis that a regime separation occurs in the log trade with the existence and extent of rent creation related to conditions in the export market. Estimated price spreads which depend on trade volume serve as evidence. These factors magnify elasticities that measure the response of Japan's prices to changes in U.S. prices. Moreover, U.S. supplies on this market are more price-inelastic than its sheer size would suggest.International Relations/Trade,

What comes to count as sustainable in Rosendal? : a study of how sustainability is being reproduced in an urban sociomaterial assemblage

Urban districts around the world are increasingly developed to be sustainable. In this thesis Iexplore what comes to count as sustainable in Rosendal, a developing urban district inUppsala, Sweden. I view Rosendal as an example of contemporary urban sustainability. Inlight of how urban sustainability initiatives tend to reproduce the status quo, my aim is toquestion taken-for-granted meanings of sustainability and open up for alternativeperspectives. I explore which everyday practices residents of Rosendal associate withsustainability, by drawing upon practice-theoretical approaches. Additionally, I analyse theSustainability in Rosendal discourse by focusing on the perspectives of Uppsala Municipalityand property developers. I approach Rosendal as an urban sociomaterial assemblage,constantly in the process of being made. This perspective helps account for the variouspractices, discourses and ‘more-than-humans’ shaping what comes to count as sustainable,while decentring humans and bringing forth human interdependency with ‘the environment’.Additionally, the emergent character of assemblages points towards the possibility for urbanenvironments to be developed differently. My findings show that prevailing sustainabilitymeanings reproduced within practices and discourses, do not initiate the type oftransformation often called for. Much of what currently comes to count as sustainable inRosendal is underpinned by a neoliberal growth logic where attractive districts are developedfor the chosen few. I show how more-than-human actants, including allotments, cars andwooden panels, contribute to what comes to count as sustainable in Rosendal. By payingattention to the effects of these actants, I envision alternative trajectories for the urbanassemblages making up Rosendal. Finally, I suggest that integrating feminist care ethics intourban development can foster more just and transformative sustainabilities

The Role of Financial Markets in the Pricing of Crude Oil: An Examination of Oil Pricing through the Structural Changes of the early Twenty-first Century

Title from PDF of title page, viewed on June 20, 2016Dissertation advisor: James I. SturgeonVitaIncludes bibliographical references (pages 160-164)Thesis (Ph.D.)--Department of Economics and Social Science Consortium. University of Missouri--Kansas City, 2016The debate over the causes of the path of the price of oil over the twenty-first century has failed to address the method of oil pricing. The thesis guiding this dissertation is that the crude oil pricing method constrains the influence of financial investors in oil futures via (1) a two-part price system, (2) the role of both spot and contract markets, and (3) the connections between the futures market and the specific physical market related to the futures contract. Market participants construct the pricing method and adjust it through historical time and context, similar to methods of pricing found in manufacturing and retail markets. The details of the physical oil market, grounded in the pricing method, leads to the application in chapter 5. The chapter examines the behavior of prices for WTI and Brent-related futures markets as well as for one light sweet and one medium sour crude oil at the US Gulf coast. Data pertinent to conditions in the physical oil market includes levels and quality of production and imports to the US, changing environmental standards, US refining complexity, demand growth and others clearly supports the path of these prices. The following illustrates the limits placed on financial investors in determination of the price of oil through the method of pricing and the conditions in the physical oil market.Introduction -- Review of the literature -- Pricing method -- Context of the crude oil market -- An application of the pricing method: the US Gulf Coast -- Conclusions and further researc
