Factoring in Vehicle Capacity in Multinomenclature EOQ-models
For the multiproduct EOQ-models the analysis of several vehicles deliveries feasibility factoring in vehicle capacity is conducted. It is proved that such deliveries with an increase in the number of vehicles that simultaneously used for a single delivery cannot be effective, if a discount is not given for the cost of such a delivery. The necessary and sufficient condition that sets the threshold level of the discount, at which the deliveries by several vehicles are able to compete with the traditional solutions, is established. The cases of numerical calculations are presented in the article.
The book focuses on the original classification of models and methods applied in logistics; analyses and summarizes approaches used in procurement, production and distribution logistics; provides either improved or newly developed models and methods solutions: intermediaries choice, ABC-XYZ analysis, EOQ, multi-item and multicomponent deliveries, determines working and safety stock as well as models and algorithms of transport and warehousing logistics. etc.
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.
Supply Chain Management in modern conditions requires close integration of business processes of transport companies and information technology. We know that today there are a large number of applications and information systems for the automation of logistics activities. Currently there is no complete and consistent classification of software products of the Transportation Management System (TMS). Their diversity is relevant in the context of the fourth industrial revolution ("Industry 4.0"). It's difficult to navigate existing and emerging information systems and choose the most appropriate. The most important class TMS products are designed to plan, organize, and account for the operation of the vehicle fleet. However, their practical use is often ineffective for several reasons. One of the common problems in the implementation of the information system is the lack of or inadequate investigation of all operating activities of the enterprise and its strategic position in the market, the analysis of information flows, evaluation of employees of business roles, mechanism of decision-making. The reason for this is the lack of logistics management competencies in the field of information technology, and on the other hand, often poor understanding of IT-managers of the transport processes. Therefore, a practical approach synchronization strategic goals, objectives, business processes, supply chain management with business logic implemented information system. The paper discusses the use of proper Zachman enterprise architecture framework as this approach. This proper framework is simple enough to understand, and is known for a long time in the IT industry. Therefore, its use in the development of the information supply chain management system in practice, it seems appropriate for small and medium-sized freight enterprises. It is known that the business processes of all transport companies in general are often very similar. However, in practice often requires a flexible adaptation of the information system for each of them.
This book constitutes the thoroughly refereed post-conference proceedings of the 8th International Conference on Learning and Optimization, LION 8, which was held in Gainesville, FL, USA, in February 2014. The 33 contributions presented were carefully reviewed and selected for inclusion in this book. A large variety of topics are covered, such as algorithm configuration; multiobjective optimization; metaheuristics; graphs and networks; logistics and transportation; and biomedical applications.
The article covers innovations in stategical logistic managment of a trade company: defining the optimal number of branches depending on the demand. All parameters in the model are dynamic: the cost of delivery, the cost of storing and the cost of rent of the warehouse. In the model were used the modified method of fuzzy cluster analysis, genetic algorithms, theory of optimal control. The model was applied for an alcohol trade company for which it was estimated the optimal number of branches on the territory of Russia with several variants of their accommodation. For all branches it was calculated the schedule of deliveries and the changes in warehouse’s capacity.
To serve target customers better than their competitors, supply chain management (SCM) teams today look into new technologies such as Big Data, Internet of Things (IoT) and Blockchain. These new technologies allow managers to develop and provide complex supply chain services and products faster with improved reliabilities. With these technologies, SCM teams can build complex models of a supply chain or systems of supply chains using a data-driven approach. With the growth of aviation domain across the world, there has been increasing demand in aircraft for airlines and other customers. In this domain, SCM teams deal with complex networked supply chains for aircraft’s spare part purchase and delivery for aircraft’s maintenance and repair. Aircraft’s spare parts are shipped to single assembly hubs, located globally. All parts come with certain life expectancy, specific requirements and maintenance attributes. With thousands of spare parts, hundreds of parameters, and number of manufactures distributed globally, SCM team need to deal with very large amount of data. In this paper, we use an industrial scenario of aviation industry SCM to demonstrate the necessity of having decentralized system based on distributed data-driven application technologies such as Blockchain, not only to assist in maintaining inventory of the aircraft’s parts but also to monitor the performance, usage, etc. This will help to achieve a transparent network of supply chain for aircraft’s parts and reduce the risk of availability of aircraft’s parts in black market. These new data-driven technologies when embedded into SCM scenarios will help the SCM managers to analyse the supply, demands, source of availability of spare parts and provide methods to procure them from the right sources.
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.
