Оптимизация расходов оператора при распределении вычислительной нагрузки между серверами в интеллектуальных транспортных системах
We consider the problem of cars-to-train assignments, routing and scheduling, which is to minimize the weighted average time of transportation orders execution by consistently choosing the compound of trains, their routes from origins to destinations, and schedules. We offer the new integer problem settings to account for different cases of practical constraints.
This paper describes a prototype distribution network planning tool based on an iterative approach using a combination of mixed-integer linear programming and simulation. The prototype is implemented using an open-source optimization package GLPK and Anylogic software.
Traffic jam on the road network of cities, increasing transportation costs and other negative consequences, require new solutions to improve mobility in the traffic. This problem is one of the most important for old industrial cities, where it is impossible to expand the road network. This article is analyzed of the main ways to improve traffic management in old industrial city of using new innovation modern transport systems.
Generalized error-locating codes are discussed. An algorithm for calculation of the upper bound of the probability of erroneous decoding for known code parameters and the input error probability is given. Based on this algorithm, an algorithm for selection of the code parameters for a specified design and input and output error probabilities is constructed. The lower bound of the probability of erroneous decoding is given. Examples of the dependence of the probability of erroneous decoding on the input error probability are given and the behavior of the obtained curves is explained.
The dynamics of a two-component Davydov-Scott (DS) soliton with a small mismatch of the initial location or velocity of the high-frequency (HF) component was investigated within the framework of the Zakharov-type system of two coupled equations for the HF and low-frequency (LF) fields. In this system, the HF field is described by the linear Schrödinger equation with the potential generated by the LF component varying in time and space. The LF component in this system is described by the Korteweg-de Vries equation with a term of quadratic influence of the HF field on the LF field. The frequency of the DS soliton`s component oscillation was found analytically using the balance equation. The perturbed DS soliton was shown to be stable. The analytical results were confirmed by numerical simulations.
Radiation conditions are described for various space regions, radiation-induced effects in spacecraft materials and equipment components are considered and information on theoretical, computational, and experimental methods for studying radiation effects are presented. The peculiarities of radiation effects on nanostructures and some problems related to modeling and radiation testing of such structures are considered.
