Специальный аспект эффективности EOQ-модели с арендой мест хранения и учетом фактора грузовместимости

The article discusses the special class of EOQ models which are relevant to numerous practical applications. The models of this type take into account the vehicle capacity used for goods delivery, as well as the costs of goods warehousing in the form of warehouse slots rent payments. Models also take into account that a current consignment sales revenue partially covers the regular supply purchase costs. This will not only make profit on each reorder interval, but also increase the working capital profitability. These factors, which are not counted in most traditional EOQ models, have a significant impact on the effectiveness of actual supply chains of various types. As applied to parameters of the described EOQ model the article sets out the conditions which would allow the possibility of payment based on revenues of the relevant supply chains, taking into account the working capital. To take into account the various practical approaches to optimizing the systems of the specified type the general and special cases are considered, taking into account the time value of money and without it correspondingly. Defining the conditions mentioned above allows to allocate a specified class of EOQ inventory management models, and also provides the opportunity to implement the optimization procedures for specified types of models considering both the vehicle capacity and the time value of money. The developed models adequacy, as well as the convenience and simplicity of their use for specific supply chains are illustrated by the practical examples and calculations.
