Описание: To a large extent, the air cargo market is a B2B service market between air cargo carriers and forwarding companies. Sellers strive to mitigate risk by engaging in advance sale of capacity via long-term contracts. However, these contracts often leave buyers with an incentive to default if unforeseen price and demand movements occur. This work proposes capacity options as an alternative contract type providing the desired flexibility and shows how capacity can be priced through option contracts. The analysis is conducted by means of an analytical multivariate optimization model under price and demand uncertainty. An application case study conducted on the basis of empirical data from a leading German air cargo carrier illustrates the financial potential. Furthermore, it is shown how capacity-option contracts integrate into the context of air cargo revenue management.

Описание: Because the theoretical part of the book is based on the calculus of variations, the exposition is very transparent and requires mostly a trivial mathematical background. In the case of open-loop optimal control, this leads to Pontryagin’s Minimum Principle and, in the case of closed-loop optimal control, to the Hamilton-Jacobi-Bellman theory which exploits the principle of optimality.Many optimal control problems are solved completely in the body of the text. Furthermore, all of the exercise problems which appear at the ends of the chapters are sketched in the appendix.The book also covers some material that is not usually found in optimal control text books, namely, optimal control problems with non-scalar-valued performance criteria (with applications to optimal filtering) and Lukes’ method of approximatively-optimal control design.Furthermore, a short introduction to differential game theory is given. This leads to the Nash-Pontryagin Minimax Principle and to the Hamilton-Jacobi-Nash theory. The reason for including this topic lies in the important connection between the differential game theory and the Hinfinity-control theory for the design of robust controllers.
Описание: The task to develop a practicable simulation tool for optimal control of soil vapor extraction was attacked by an interdisciplinary group consisting of
mathematicians, soil physicists, chemists and in cooperation with a remediation company. The purpose of this book is to describe the latest and most appropriate mathematical and
numerical methods for optimizing soil venting and to demonstrate the application beginning with a conceptual mathematical model, the derivation and estimation of model parameters,
generation of parameter distributions, sensitivity analysis, model calibration and numerical analysis of two spillage test cases, and stochastic optimization. The monograph considers
mathematical, numerical, technical aspects as well as the practical significance.
This book will be of interest to applied mathematicians, geophysicists, geoecologist, soil
physicists, and environmental engineers.
Описание: Updated to conform to Mathematica® 7.0, this second edition shows how to easily create simulations from templates and solve problems using Mathematica. Along with new sections on order statistics, transformations of multivariate normal random variables, and Brownian motion, this edition offers an expanded section on Markov chains, more example data of the normal distribution, and more attention on conditional expectation. It also includes additional problems from Actuarial Exam P as well as new examples, exercises, and data sets. The accompanying CD-ROM contains updated Mathematica notebooks and a revised solutions manual is available for qualifying instructors.
Описание: It presents recent and pressing issues in stochastic processes, control theory, differential games, optimization, and their applications in finance, manufacturing, queueing networks, and climate control. The book is dedicated to Professor Suresh Sethi on the occasion of his 60th birthday, in view of his distinguished career.
Описание: The purpose of this book is to acquaint the reader with the developments in bilinear systems theory and its applications. Bilinear systems can be used to represent a wide range of physical, chemical, biological, and social systems, as well as manufacturing processes, which cannot be effectively modeled under the assumption of linearity. This book provides a unified approach for the identification and control of nonlinear complex objects that can be transformed into bilinear systems, with a focus on the control of open physical processes functioning in a non-equilibrium mode. A wide class of non-linear control systems can be approximated using novel algorithms motivated by bilinear models. The goal of this book is to describe new methods, heuristics, and optimality criteria with less demanding computational complexity than exact criteria that result in robust adaptive algorithms. Emphasis is placed on three primary disciplines influencing bilinear systems theory: modern differential geometry, control of dynamical systems, and optimization theory.
Описание: The coordinated use of autonomous vehicles has an abundance of potential applications from the domestic to the hazardously toxic. Frequently the communications necessary for the productive interplay of such vehicles may be subject to limitations in range, bandwidth, noise and other causes of unreliability.The monograph is divided into six parts covering introductory, theoretical and experimental material and featuring:• an overview of the use of consensus algorithms in cooperative control;• consensus algorithms in single- and double-integrator dynamical systems;• consensus algorithms for rigid-body attitude dynamics;• rendezvous and axial alignment, formation control, deep-space formation flying, fire monitoring and surveillance.Notation drawn from graph and matrix theory and background material on linear and nonlinear system theory are enumerated in six appendices. The authors maintain a website at which can be found a sample simulation and experimental video material associated with experiments in several chapters of this book.Information consensus guarantees that vehicles sharing information over a network topology have a consistent view of information critical to the coordination task. Assuming only neighbor-neighbor interaction between vehicles, Distributed Consensus in Multi-vehicle Cooperative Control develops distributed consensus strategies designed to ensure that the information states of all vehicles in a network converge to a common value. This approach strengthens the team, minimizing power consumption and the deleterious effects of range and other restrictions.Academic control systems researchers and their counterparts in government laboratories and robotics- and aerospace-related industries will find the ideas presented in Distributed Consensus in Multi-vehicle Cooperative Control of great interest. This text will also serve as a valuable support and reference for graduate courses in robotics, and linear and nonlinear control systems.

Описание: After motivating examples, this monograph gives substantial new results on the analysis and control of linear repetitive processes. These include further applications of the abstract model based stability theory which, in particular, shows the critical importance to the dynamics developed of the structure of the initial conditions at the start of each new pass, the development of stability tests and performance bounds in terms of so-called 1D and 2D Lyapunov equations. It presents the development of a major bank of results on the structure and design of control laws, including the case when there is uncertainty in the process model description, together with numerically reliable computational algorithms. Finally, the application of some of these results in the area of iterative learning control is treated --- including experimental results from a chain conveyor system and a gantry robot system.
