The technique, which allows to makes modeling of parameters of use of vehicles and infrastructure of multimodal logistic projects of delivery of freights with participation of railway transport, a transshipment complex and navy presented in article. Is given the example of use of this technique in the developing the logistic part of the investment project of new steel works in the city of Beloretsk.
The paper studies the problems of venture investment development in Russia. The conclusion on the need for serious changes in the existing legislation of Russia in the sphere of venture investment is made.
The article is dedicated to the prospects of intermodal contrailer transportation in Russia. The comparative analysis of the accompanied and non-accompanied contrailer services is given. Different types of contrailer service operators are examined. The "Concept of contrailer transportation development in the 1520 area" is critically analysed. The possible efficiency of introducing contrailer transportation in Russia is evaluated.
The purpose of this research is the analysis of the most crucial internal parameters influencing financial decisions connected with personal perception of entrepreneurial activities and objective characteristics of the project. Given received assessments, entrepreneurs with higher education and permanent job in majority of cases apply for informal loans to finance business with low value added and minimal start-up costs. Thus entrepreneurship takes the form of self-employment and not an activity that generates new products and technologies.
A model for organizing cargo transportation between two node stations connected by a railway line which contains a certain number of intermediate stations is considered. The movement of cargo is in one direction. Such a situation may occur, for example, if one of the node stations is located in a region which produce raw material for manufacturing industry located in another region, and there is another node station. The organization of freight traﬃc is performed by means of a number of technologies. These technologies determine the rules for taking on cargo at the initial node station, the rules of interaction between neighboring stations, as well as the rule of distribution of cargo to the ﬁnal node stations. The process of cargo transportation is followed by the set rule of control. For such a model, one must determine possible modes of cargo transportation and describe their properties. This model is described by a ﬁnite-dimensional system of diﬀerential equations with nonlocal linear restrictions. The class of the solution satisfying nonlocal linear restrictions is extremely narrow. It results in the need for the “correct” extension of solutions of a system of diﬀerential equations to a class of quasi-solutions having the distinctive feature of gaps in a countable number of points. It was possible numerically using the Runge–Kutta method of the fourth order to build these quasi-solutions and determine their rate of growth. Let us note that in the technical plan the main complexity consisted in obtaining quasi-solutions satisfying the nonlocal linear restrictions. Furthermore, we investigated the dependence of quasi-solutions and, in particular, sizes of gaps (jumps) of solutions on a number of parameters of the model characterizing a rule of control, technologies for transportation of cargo and intensity of giving of cargo on a node station.
This proceedings publication is a compilation of selected contributions from the “Third International Conference on the Dynamics of Information Systems” which took place at the University of Florida, Gainesville, February 16–18, 2011. The purpose of this conference was to bring together scientists and engineers from industry, government, and academia in order to exchange new discoveries and results in a broad range of topics relevant to the theory and practice of dynamics of information systems. Dynamics of Information Systems: Mathematical Foundation presents state-of-the art research and is intended for graduate students and researchers interested in some of the most recent discoveries in information theory and dynamical systems. Scientists in other disciplines may also benefit from the applications of new developments to their own area of study.
One of the most important indicators of company's success is the increase of its value. The article investigates traditional methods of company's value assessment and the evidence that the application of these methods is incorrect in the new stage of economy. So it is necessary to create a new method of valuation based on the new main sources of company's success that is its intellectual capital.
