Evaluation of Bakery Efficiency Using the CCR-DEA Model — Przegląd piekarski i cukierniczy 2021-3

The article addresses the problem of evaluating the efficiency of bakeries in order to compare their performance and identify the most effective units. The author shows that this issue belongs to the field of operations research, specifically Data Envelopment Analysis (DEA-CCR), used for benchmarking similar organizations.

In the technical part, a mathematical model is presented in which bakeries are compared based on multiple inputs (e.g. infrastructure, machines, labor, costs) and outputs (e.g. production volume, profit). The method uses linear programming and systems of inequalities to calculate efficiency scores. As shown in the tables and formulas (page 1–2), each bakery is evaluated through a set of constraints and optimization equations .

As a result, efficiency scores were obtained (e.g. Łopata and Lipinki = 1 as benchmark units, Bobry = 0.705), allowing identification of the best-performing bakeries and those requiring improvement. The article demonstrates that DEA and linear programming as methods of operations research enable objective efficiency assessment and support managerial decision-making.
