Принятие управленческих решений в случае возникновения дефицита
Stock-out – an inventory shortage, is a situation which periodically or constantly
retailers, networks of retail trade (and other commercial organizations connected
with replenishment and stocks expenditure) face worldwide. Numerous publications
of foreign authors proposing practical solutions for such organizations is
a vivid example of it. Some retail chain stores and enterprises even issue guidebooks
to handle stock-out.
In domestic literature, there are publications describing various stock-out
forms, as well as recommendations associated with the decision-making on them.
Nevertheless, the experience connected with the prevention and struggle
against the stock-out consequences is uncoordinated, lacks common structure, and
sequence of actions. An enterprise facing stock-out receives only fragmentary data
on the nature of this phenomenon, necessary instruments of influence and the sequence
To give an idea of the existing spectrum of analytical approaches and possible
practical solutions, is one of the main objectives of this article. At the same time,
issues related directly to determining the stock volume and other parameters of a
company's inventory management system are considered. Based on the analysis
of the issues described above, a possible algorithm of actions an organization can
follow in the event of a stock-out, is presented. The possible development of an approach
to manage the most complex stock-out case – «with a lost demand» is also
It is developed and presented an approach to inventory management EOQ-model optimization in this paper taking into the deferrals provided for the order cost payments. They summarize the results for the traditional EOQ-models taking into account the deferrals of payments which relate to payment of the batch of goods, with the payment of storage costs, and of the delivery costs payment. Presented modifications of EOQ-formulas will allow for managers to while considering the above features also to take into account he specificity costs of storage charging, in the form of rent, and for the used place on stock, to improve the decisions on the organization of the supply chain quality.
The article presents the derived formulas for calculating the parameters of the EOQ model that takes into account simultaneous multi-product supplies and differential discounts as well as the developed algorithm for calculating the parameters of this model.
The article presents a special modification of the EOQ-formula for a diversified EOQ-model of inventory management with account to specifics of lot deliveries. It will allow managers to determine the optimal parameters of the inventory management strategy if it is required to take into account the following features: 1) the possibility of order payment deferral; 2) time value of money at cashflow modelling 3) incomes specifics, when the proceeds come with a delay 4) specificity of storage costs payment (in form of rent or by the occupied storage space). In addition, the article specifies some options related to the possibility of using such a formula if it is necessary to additionally take into account: a) the restriction on the allowable length of the delay in payment of goods, so that the point of receipt of the proceeds did not exceed the corresponding reorder interval duration (on average); b) the vehicle capacity. The presented research materials on optimization of supplies will allow managers to estimate the effect of permissible delays in order payments, delays in receipt of proceeds, and the factor of vehicle capacity on the parameters of the optimal strategy of inventory management. The procedures of EOQ formula modification for inventory management systems are performed in relation to interesting and business-relevant models of this type that correspond to efficient deliveries, where these delays allow to make order payments from revenue at reordering intervals.
The article summarizes the results of optimization of the inventory management strategy, taking into account the joint impact of factors that are important for the practice: the cargo capacity of the vehicle, delays in payment for the cost of goods, delays in payment for storage costs, delays in payment for the cost of delivery of goods. A new modification of the EOQ-formula is presented, which will allow to take into account the specified specificity of the supply chain operation.
It gives us great pleasure to welcome you on the 17th edition of the International Conference on Harbor, Maritime & Multimodal Logistics Modeling and Simulation (HMS 2015) part of the 12th International Multidisciplinary Modeling and Simulation Multiconference (I3M). HMS 2015 upholds a long tradition started in 1999 in the field of simulation and computer technologies applied to logistics, supply chain management, multimodal transportation, maritime environment and industrial logistics. As time goes by, HMS looks at the future of science and practice seeking to capture new and emerging development trends but not only. As challenges are put forward by the fast changing social, technical and economic situation, a great effort has been done to set up an advanced scientific program with lots of talks, seminars, research presentations and discussions. Valuable research experiences need to be shared for developing new knowledge and generating new groundbreaking ideas. This is, in essence, the inner meaning that HMS nurtures. Therefore HMS gives a not‐to‐be‐missed chance of networking among colleagues to set up new relations and strengthening long‐established ties on joint research interests. It’s our firm determination that HMS 2015, as indeed past and future editions, could end with some strong take‐home messages rewarding merits and scientific excellence. To this end, HMS provides the Authors of the best papers with the opportunity to extend their works for publication in International Journals Special Issues.
The sections of the discipline "Economic and mathematical methods and models in logistics" are presented, related to procedures for optimizing supply chains on the basis of methods of mathematical theory of inventory management, methods and models of graph theory, methods for solving the transport problem, methods for optimizing flows in networks, optimizing network project schedules. The foundations of the method of simulation are given.
The article presents a model of optimization of inventory control strategy in terms of risk in the supply chain enterprises meat industry. On study the approach to the transformation of the model under conditions of uncertainty in the model of risk management by using the method of decision tree. Based on the method of decision tree for the corresponding model in terms of risk determine the optimal strategy, which provides a different attitude to risk.
Smoking is a problem, bringing signifi cant social and economic costs to Russiansociety. However, ratifi cation of the World health organization Framework conventionon tobacco control makes it possible to improve Russian legislation accordingto the international standards. So, I describe some measures that should be taken bythe Russian authorities in the nearest future, and I examine their effi ciency. By studyingthe international evidence I analyze the impact of the smoke-free areas, advertisementand sponsorship bans, tax increases, etc. on the prevalence of smoking, cigaretteconsumption and some other indicators. I also investigate the obstacles confrontingthe Russian authorities when they introduce new policy measures and the public attitudetowards these measures. I conclude that there is a number of easy-to-implementanti-smoking activities that need no fi nancial resources but only a political will.
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.

At present many industries reveal tendency for setting up of vertically integrated companies (VIC) the structure of which unites all technological processes. This tendency proved its efficiency in oil industry where coordination of all successive stages of technological process, namely, oil prospecting and production -oil transportation - oil processing - oil chemistry - oil products and oil chemicals marketing, is necessary. The article considers specific features of introduction of "personnel management" module at enterprises of oil and gas industry.
