Analysis of the Risk of a Shortage of Operating Stocks in an Item-Unbalanced Spare Parts Supply System

Analysis of the Risk of a Shortage of Operating Stocks in an Item-Unbalanced Spare Parts Supply System

Paper in proceedings (conference paper)

Inventory creation of rechargeable batteries for vital operating equipment requires continuous monitoring of material flows and their optimization. Optimizing inventory processes and material flows in logistics chains is a complex task that depends entirely on knowledge of data on past flows and plans or predictions of future flows. Equally important are knowledge of the service life of materials and knowledge of mathematical models, including the possibilities and regularities of their application for various model situations. The input data for each specific subject reflects not only the business task, but also its concept and position in the sales or production market. It is obvious that the concept of inventory creation will be different for a manufacturing company, different for a commercial subject and different for a state-financed entity. The state-financed and managed entities have specific requirements for the creation of inventories arising from the purpose of their existence and concurrently from the restrictions given by the management systems and regulation of financial flows. It is the limitation resulting on the one hand from the methodologies and laws governing the principles of public procurement that may be in partial conflict with internal normative acts. Using the analysis of input parameters of purchases with subsequent application to a specific inventory creation model from inventory theory, the influence of standard inventory creation processes on the speed and completeness of spare parts deliveries and the resulting level of the maximum required amount of held inventory is shown on the selected entity.
