Логистическая модель поставки продукции со склада предприятия
In the article, the question of the organization of the mixed transportations of export freights is considered. Optimum giving of cars pays off with use of the developed model of interaction of railways transport and a warehouse from the enterprise.
Methodology of solving the problem of warehousing logistics is viewed, including the complex of problems of constructing warehousing network and optimizing warehousing economy. It is shown, that solving the problem of warehousing logistics lies in gradual consideration and mplementation of such taska as working out logistic strategy, including operating of warehousing network; forming optimal network in frame of locating warehousing capacities; projecting (reorganizing) warehousing economy; working out master plan of warehousing economy; working out optimal system of warehousing and volumetric planning decisions.
The problems of managing logistic process at the warehouse are analyzed in frame of optimizing parameters of trade flows, going through warehouse.
The Proceedings of reports presented at the 12th International Conference on Road Organization and Safety in Big Cities (St. Petersburg, 28-30 September 2016) covers a wide range of theoretical and practical issues related to road deaths prevention (up to “zero” level) – conceptual, legal, organizational, technological, informational, etc. Following the goal it builds up the knowledge base on the space (complete set) of factors affecting the level of road safety, as well as studies the preventive measures for potential causes of road crash fatalities. The research area includes all levels of the state system hierarchy related to road safety: from the first (the road) level, revealing the final causes of road crashes such as speeding, driving in the opposite direction, etc., to the upper government management levels that can bear the root causes of road crash fatalities and casualties. Subjects of research include general and regional road safety systems, technologies (techniques, methods, mechanisms) for their efficient organization and management, as well as the organization of various subsystems, functionally connected by the system-wide goal. The articles in these Proceedings focus on various subjects, such as the quality of legislative and regulatory issues ensuring system wide activities on road deaths prevention and their rigorous practical implementation; issues of development of transport infrastructure, including bicycles; issues of intellectualization of systems and processes, formalization (including mathematical) of modeling and design tasks of various objects in the system, their effectiveness assessment and sustaining the latter in the operational mode; issues of justification and practical application of the mechanisms of formation of the main functional properties of the systems that make up the quality and create possibilities for on-line monitoring of the functioning processes and prediction of their condition; issues of GIS modeling of road networks, modeling of transport accidents, prevention of drinking and driving, etc. The Conference holders believe that these materials will help find solutions and promote a transfer of the current road safety practices in Russia to a rigorous system approach, to methods of continuous (in CALS-technologies terms) modeling (improvement) of the road crash deaths prevention systems – the only generally recognized scientific tool for efficient complex systems study, to the development of a sustainable knowledge base and targeted experts systems – a tool to manage competence, responsibility and loyal motivation of personnel, and ultimately - to saving lives on the roads.
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.
