We describe vendor managed inventory concept of supply chain management. We propose the idea of using this metodology for the problem of motor fuel distribution from oil depots to filling gas oil stations. The advantages, risks and limitations of the concept introduction for this problem are shown.
Russian mining industry experiences a rapid growth providing an attractive market for suppliers of mining equipment. However, it's a customer-dominated market. The customers set stringent requirements for the initial equipment supply, as well as for the after-sale service and spare parts supply. The manufacturers of mining equipment are thus facing the need to rigorously analyze their supply chain, to develop a reasonable customer service policy and to adjust the supply chain to meet the requirements of the service policy. To fulfill the after-sale maintenance requirements, the manufacturers must stock spare parts within the supply chain and to design inventory control policies. This paper presents an agent-based simulation approach for estimation of the supply chain's key performance indicators and to explore the service - cost trade-off. The conceptual model and the description of its implementation in Anylogic 8.4 software are provided. A case-study of a global mining equipment manufacturer's branch operating in Russia is described. The model is used to estimate the inventory control policy parameters required to meet the target customer service level, to compare make-to-order against make-to-stock supply strategies, as well as to explore the service level - cost trade-off.
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 of actions. 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 considered.
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.
