The focus of this book is risk assessment methodologies for network architecture design. The main goal is to present and illustrate an innovative risk propagation-based quantitative assessment tool. This original approach aims to help network designers and security administrators to design and build more robust and secure network topologies. As an implementation case study, the authors consider an aeronautical network based on AeroMACS (Aeronautical Mobile Airport Communications System) technology. AeroMACS has been identified as the wireless access network for airport surface communications that will soon be deployed in European and American airports mainly for communications between aircraft and airlines. It is based on the IEEE 802.16-2009 standard, also known as WiMAX. The book begins with an introduction to the information system security risk management process, before moving on to present the different risk management methodologies that can be currently used (quantitative and qualitative). In the third part of the book, the authors’ original quantitative network risk assessment model based on risk propagation is introduced. Finally, a network case study of the future airport AeroMACS system is presented. This example illustrates how the authors’ quantitative risk assessment proposal can provide help to network security designers for the decision-making process and how the security of the entire network may thus be improved.

MIMO-OFDM for LTE, WIFI and WIMAX: Coherent versus Non-Coherent and Cooperative Turbo-Transceivers provides an up-to-date portrayal of wireless transmission based on OFDM techniques augmented with Space-Time Block Codes (STBCs) and Spatial-Division Multiple Access (SDMA). The volume also offers an in-depth treatment of cutting-edge Cooperative Communications. This monograph collates the latest techniques in a number of specific design areas of turbo-detected MIMO-OFDM wireless systems. As a result a wide range of topical subjects are examined, including channel coding and multiuser detection (MUD), with a special emphasis on optimum maximum-likelihood (ML) MUDs, reduced-complexity genetic algorithm aided near-ML MUDs and sphere detection. The benefits of spreading codes as well as joint iterative channel and data estimation are only a few of the radical new features of the book. Also considered are the benefits of turbo and LDPC channel coding, the entire suite of known joint coding and modulation schemes, space-time coding as well as SDM/SDMA MIMOs within the context of various application examples. The book systematically converts the lessons of Shannon's information theory into design principles applicable to practical wireless systems; the depth of discussions increases towards the end of the book. Discusses many state-of-the-art topics important to today's wireless communications engineers. Includes numerous complete system design examples for the industrial practitioner. Offers a detailed portrayal of sphere detection. Based on over twenty years of research into OFDM in the context of various applications, subsequently presenting comprehensive bibliographies.

Обобщенная оптимизационная задача производственно-транспортных процессов на предприятии
Данная статья содержит модель обобщения трех ранее известных задач линейного программирования: 1) производственной задачи (классическая постановка), решение которой представляет собой вектор количества произведенных конечных продуктов, найденный при ограничениях на количество ресурсов с учетом максимизации прибыли; 2) задачи учета времени, которую можно трактовать как дополнительное ограничение в общей системе ограничений и которая относится к целевой функции (минимизация затраченного суммарного времени на транспортировку груза); 3) транспортной задачи, решение которой определяет маршруты и объемы перевозок продукции на графе дорожной системы. Постановка задачи, объединяющей все три вышеперечисленные проблемы в одну комплексную, в точности подходит к случаю, когда стоит задача определения объема производства различных типов продукции с последующим определением маршрутов перевозок в каждый пункт потребления (потребителю) с целью минимизации с учетом пропускной способности графа дорожной сети транспортных издержек. Впервые задача была сформулирована для объектов лесоперерабатывающего комплекса в процессе производства и реализации товара. Настоящая статья посвящена построению линейной смешано-целочисленной модели и нахождению метода оптимального решения производственно-транспортной задачи. Такую задачу можно отнести к классу нетривиальных комбинаторных задач принятия решений на предприятии.
Синтез стохастического регулятора для вывода нелинейного дискретного объекта в заданное множество состояний
Автором рассматривается задача управления на многообразиях сложным (плохо формализуемым, нелинейным, с наличием неустойчивых состояний) объектом второго порядка, представленным в виде системы нелинейных разностных уравнений, правые части которых могут содержать неопределенности стохастической природы. Представлен алгоритм для аналитического конструирования закона управления, обеспечивающего стабилизацию исходной системы в окрестности заданного целевого множества. Дается информационная модель системы робастного управления на многообразиях, обусловленная двойственностью постановки задачи: стохастическим шумом измерительного типа и необходимостью корректного описания целевого множества. Приводятся результаты численного моделирования сконструированной системы управления для экономической балансовой модели.
Гибридное кибермоделирование в экономике: теория акторных сетей, симуляция, НЕ-факторы и сверхнечеткая логика
Компьютерное имитационное моделирование обычно заключается в запуске параллельных взаимодействующих вычислительных процессов, аналогичных реальным процессам, но в виртуальных пространствах и времени. Такая модель позволяет получать метрологические характеристики реального процесса, натурное исследование которого или очень дорого, или невозможно по причине риска получения невосполнимого ущерба. Однако для создания модели иногда нет полного набора исходных данных удовлетворительного уровня значимости, и создавать модель приходится в условиях неопределенности. В таком случае наряду с программами, получающими метрологические характеристики, возникает необходимость включать в модель программы, реализующие методы искусственного интеллекта для получения новых квалиметрических характеристик. В этом направлении идет развитие современных методов имитационного моделирования и соответствующего software.
