• Optimal Order Quantities Determined by the Economic Order Quantity Method — Przegląd piekarski i cukierniczy 2020-12

The article addresses the problem of determining the optimal order quantity in a bakery in order to minimize total costs related to inventory management. The author shows that this issue belongs to the field of operations research, specifically the Economic Order Quantity (EOQ) model, which is a classical optimization method. In the technical part, a mathematical model is presented that includes different types of costs: ordering costs, holding costs, and capital-related costs. The model uses a formula for EOQ, which allows calculating the optimal order size based on these parameters. The analysis also involves cost functions and calculations of total annual inventory cost, supported by a graphical interpretation of cost behavior depending on order size . As a result, the optimal order quantity was determined (Q = 102 units), which minimizes total costs. The article demonstrates that mathematical optimization methods in operations research, such as EOQ, enable more efficient inventory management and support rational economic decision-making in production enterprises
