• The Process of Minimizing Flour Purchase Costs Using an Operations Research Algorithm — Przegląd piekarski i cukierniczy 2021-10

The article addresses the problem of minimizing flour purchasing costs in a bakery while maintaining required production levels. The author shows that this issue belongs to the field of operations research, specifically linear programming, used to optimize resource allocation under constraints. In the technical part, a mathematical model is presented with decision variables representing amounts of different types of flour, a cost-minimizing objective function, and a set of linear constraints related to production requirements (bread, rolls, pastries) and processing time. The model is solved using the simplex method, based on systems of linear inequalities and supported by computational tools . As a result, the optimal solution indicated using only one type of flour (R3) in a specific quantity, achieving the lowest possible daily cost (29,744 PLN) while satisfying all constraints. The article demonstrates that linear programming as a method of operations research enables effective cost optimization and rational decision-making in production processes. Publication link: https://sigma-not.pl/zeszyt-6746-przeglad-piekarski-i-cukierniczy-2021-10.html
