Linear boundary value problems for functional differential systems are considered when the number of boundary conditions is greater than the dimension of the system in the case of approximate fulfilment of boundary conditions. Boundary value problems are connected with studying the problems on the attainability for given indexes of development to the economic system under consideration. The approach is based on theorems whose conditions allow one to check up them by special reliable computing procedures. Dynamic models under consideration cover many kinds of dynamic models with aftereffect (integro-differential, delayed differential, differential difference)

We consider linear boundary-value problems for systems of functional differential equations when the number of boundary conditions is greater than the dimension of the system. We allow the boundary conditions to be fulfilled approximately. We propose an approach based on theorems whose conditions allow the verification by special reliable computing procedures. ...

Динамические модели, рассматриваемые в этой работе, с одной стороны, представляют собой конкретную реализацию абстрактных функционально-дифференциальных уравнений. С другой стороны, они охватывают широкий класс моделей, возникающих при исследовании реальных экономических и эколого-экономических процессов с учетом эффектов последействия (запаздывания) и импульсных возмущений (шоков), приводящих к скачкообразному изменению основных показателей функционирования изучаемой системы. Рассматриваемые модели содержат одновременно как ...

Рассматриваются некоторые задачи экономико-математического моделирования, - задачи управления и задачи корректной разрешимости для динамических моделей в виде систем с запаздыванием, как для непрерывного, так и для дискретного времени. Для систем с непрерывным временем обсуждается влияние последействия в канале управления на общие затраты по целевому управлению системой. Для систем с дискретным временем рассматривается возможность коррекции противоречивых ...

For a functional differential system with continuous and discrete times, the general linear boundary value problem and the problem of control with respect to an on-target vector-functional are considered. Conditions for the solvability of the problems are obtained. Questions of computer-aided techniques for studying these problems are discussed. ...

We consider control problems for linear systems of functional-differential equations with both continuous and discrete time variables. The goal of controlling the systemunder consideration is prescribed by a finite set of linear functionals. The number of these functionals is independent of the dimension of the system. We describe the subset of controls generated by a ...

In social choice there often arises a conflict between the majority principle (the search for a candidate that is as good as possible for as many voters as possible), and the protection of minority rights (choosing a candidate that is not overly bad for particular individuals or groups). In a context where the latter is ...

This book provides a cross-cultural analysis of traditional social organization of the Old World Oikumene civilizations, which suggest that the world religions were its major determinant. The role of Christianity and Islam as determinants of social evolution is analyzed in more detail. Formal analysis performed in this book shows that though such factors as political ...

В книге обсуждаются общие закономерности эволюции Мир-Системы. Показано, что они могут описываться при помощи крайне простых математических моделей. Рассматривается соотношение между микроуровневым хаосом и высокодетерминированной динамикой на макроуровне. Анализируется соотношение между циклическими и поступательными процессами. Проанализированные данные и разработанные модели позволяют предложить ряд конкретных рекомендаций, например, выявить пути решения демографического кризиса в России. Книга представляет ...

One of the options for a more flexible approach to analyzing the reliability of supply chains is the principal component analysis (PCA). With a large number of variables describing supply chain, it is a difficult task to analyze the structure of variables in two-dimensional space. Within the analysis of the variables dependencies PCA allows to ...

We see globalization as the growth of the sizes of social systems and the increase in the complexity of intersocietal links. Thus, in certain respects, globalization may be regarded as a process connecting the past, the present, and the future—as a sort of bridge between the past and the future. The title and the composition ...
