Development of analytical models of optimizing an enterprise's logistics information system supplies

Abstract

The creation of an efficient enterprise's logistics information system requires a set of mathematical decision support models. The existing inventory models that are used in warehouse logistics have low adequacy with the real logistics processes. The research examines the reasons for the low efficiency of the basic warehouse logistics models and analyzes their development. When determining the form of the total cost function in the EOQ model, the costs of delivery and storage related to different moments of time were not taking into account. Failure to fulfill this requirement is one of the main factors affecting the adequacy of the mathematical inventory models, which are based on the EOQ model. The developed mathematical models, representing the refined Wilson's model, allow to justify the consignment delivery using several vehicles. The conditions for applying the model to the order cost, depending on the consignment size were determined. The algorithm for determining the optimal number of vehicles for the consignment delivery was developed. Using the developed mathematical models will allow making the best decisions in warehouse logistics. The findings to the EOQ model development can be used for other inventory models that will create an effective information logistics system.
