 The method of numerical simulation is used to study the effect of parameters of a simple discrete flow of inventory through a logistic three-level distribution system, as well as the parameters of the system itself, on the universal characteristics of its efficiency — relative levels of current stocks in the system and deficit indicators for end users. By flow parameters we mean the level of its power and its variation; under the system parameters - the type of applied inventory management (IM) model and the speed of reaction to the requirements for the supply of the next batch of inventory. The flow of consumer requirements arriving at the lower level of the system and causing inventory movement through the system corresponds to the Poisson law. Four basic ultrasound models IM are tested, and in each case the same model is used at all levels of the system. As a result, we obtained the corresponding number (total - 66, given in article - 22) of the experimental dependences and the regression equations adequate to them. Their brief interpretation is given from the point of economic aspects of distribution logistics. Conclusions are drawn regarding the nature of the use of the identified dependencies and the directions for further research on this issue. The study (its object and applied technologies) is not strictly tied to either a specific area of logistics (trade, industry, logistics services, etc.), or to the hierarchical level of the object of modeling (industry, distribution company, a single-plant enterprise, a production association, a large production unit, etc.).

 Managing costs and results of companies in the supply chain structure, and, as a consequence, in the context of the reproduction cycle is an important scientific problem since it determines the competitive level of domestic economy enterprises and their viability in fight for the consumer. One of the main roles in this context must belong to logistics, which is a system factor of profitability for logistic and overall costs of enterprises and supply chains. First of all, effective cost management requires determination of economic content of the central material flow and its structure, which is the main task of this article. As a result of the detailed analysis of functional activity of the enterprise which is one of components of created integrated logistics space, transformation of economic maintenance of manufacturing enterprise material flow is presented, the main forms of representation of value in system and supply chain structure of a reproduction cycle are revealed. On this basis an updated maintenance of costs and losses is submitted, which, along with the generated results, fixes in the dynamics the economic transformation of logistics flows. The revealed structure of costs, losses and indicators of effectiveness causes a number of requirements and features for the management accounting organization at the enterprise. As a result, the relevance of formation is proved and the main barriers in the account organization according to uniform policy in structure of a simple and expanded supply chain are revealed, and also the main objectives of scientific research in this field are set in this article.

The irrational organization of intra-productive material flows at the enterprise is the main reason of the increase of logistics cycle time and the emergence of additional logistics costs, reduce the capacity utilization rates, the difficulty of monitoring the production process and, as a whole, growth of the cost price of products. A study of intra-productive material flows in the company, engaged in the production and distribution of soft drinks, has revealed a number of significant problems associated with improper placement of the production equipment (mismatch between the location of the main principles of rational organization of production processes). In this article proposes an approach to the reorganization of the industrial material flow on the basis of the use of elements and instruments of various modern concepts of production logistics: Lean Manufacturing, Kanban, Theory of Constraints by E. Goldratt, Value Stream Mapping, REFA methodology. Proposals were developed on the spatial reorganization of the production process and improve the management of them with a view to ensuring the production line of the corresponding demand with minimal production and logistics costs. Given materials illustrates the effectiveness of the application of the presented approach to the production enterprise

This article demonstrates how to use the method of simulation modeling in AnyLogic in order to optimize the logistics network of industrial company operating in the industrial gas market. The model detailed basic processes associated with the transport of the product, the service requests of customers and distribution of the product to consumers. Factors were taken into account, bearing the stochastic nature, such as unevenness of production, weather conditions that affect the level of demand, the number of failures of vehicles, vehicle repair time. On the developed model, a number of scenario studies, which identified the optimal values of the control parameters of a logistics network: the number of rolling stock, additional storage capacity, minimizing the loss of the deficit and the lack of free rolling, leading ultimately to lower total cost of ownership (TCO) .

Logistical context of a business model

MAGAZINE №1 (66) February 2015


CATEGORY Terminology in Logistics and SCM


Multi- and interdisciplinary nature of the supply chain management and modern logistic strategic potential define logistical context of a business model.

Some implications have been made based on the reviewed articles about logistics and business models.  (1) It is evident that authors have little agreement about logistical challenges in business models that can be explained by lack of unity in understanding the business model concept.  (2) Logistics and business models are interrelated. Logistics influences efficiency, results and possibilities of a business model development. Moreover, a business model defines requirements for logistics. (3) Significance of logistics in a business model is determined by the object of logistics which is an aggregate of interrelated material, information and financial flows. The system of material flows ensures management of information flows in the value chain. This in turn is a basis of fair distribution of financial results between supply chain partners.

The author uses a consolidated definition of a business model as an object that deals with assessment, creation, distribution and supply of value to the client, and also with allocation of profit collected thanks to its acknowledgement on the market. The researcher attempts to update logistics as an instrument of developing and applying a business model. It is emphasized that it has an unquestionable primary role in the chain to create, distribute and supply value to the client.

The author suggests and describes the model of a logistics business model and develops a system of indicators to evaluate and analyze logistics in a business model.  The system of indicators can be used to complete two tasks. The first task is to evaluate logistical component of a business model to develop logistical strategy in a company. The second task is to analyze the results of logistical activity in the framework of a business model to understand the rationale to develop a new business model in a company.
