Heading:PROBLEMS AND OPINIONS

MRP concept: choice of inventory management strategy (Part II)

The article examines the main inventory management methods at dependent demand. The analysis showed that the results are debatable and, in fact, do not allow definitely choose the optimal inventory management strategy. To solve the problem calculations were carried out using the basic management strategies. Data from the literature and the authors' own materials were used for comparative calculations; comparison of the obtained results allowed to determine the best strategy in terms of minimum cost.

Versions of the motion forms of resource flows

The article presents the classification of resources movement forms, the preconditions and sequence the designing, formation and optimization of resources flows within logistics systems.

Key words. Logistics, resources flows, movement forms, front, channel, costs, time.

Development of methods and cost calculation algorithm for the milk delivery from the producers to the consumer-processor

Due to the difficult economic situation in Russia, providing of product market is very topical issue nowadays. Diary branch also needs rapid development. Created methodology of costs counting of the whole complex of services allows to simplify the work of logistics companies, which deliver milk from the producing regions to milk processors. Computer programme development is being held now on basis of presented algorithms in order to automize the way of costs counting.

Key words. Logistic services, milk, regions, methodology, approbation, program.

Multi-criterial model of warehouses optimal location in the supply chain (Part I)

The design of logistics chain is strategically important issue for almost every company. There is a large variety of model formulations and solving algorithms, which vary in fundamental assumption, mathematical complexity, etc. In this paper classification of models of dislocation of logistic capacities is considered and the multicriteria model of optimum dislocation of warehouses in supply chains is offered.

Key words. Facility location, logistics networks, mathematical modelling, optimum dislocation of warehouses.

System approach to the resources flows management

The paper contains the updated classification of material flows, the substantiated provisions of a system approach to the resources flows management, the proposed sequence of the design and optimization of material flows in the logistics system.

Key words. Logistics, logistics management, logistics flow, system approach, classification, logistics system.

Contemporary logistics problems in the transportation sphere

The article is dedicated to positioning of logistics as a certain kind of organizational activity oriented to particular objects of civil law, the most important of which are products (goods) and transportation services (services).

Model of the logistic structure (Part II)

In the paper is described the formation of a mathematical model of the logistics structure. The model provides a formal representation of the state of the structure and systematization of assets. On the set of states the model makes it possible to analyze the effectiveness of past and choose the preferred options for future activities. On the model of the illustrative structure is shown the implementation of some of the practical tasks of situations assessment.

Key words. Model of logistic, analysis of retrospective, assessment of the prospects, management of structure.
