| Abstract | ||||
| This study introduces a new application of aggregate production planning (APP) in the manufacturing of carbon steel pipes and hot induction bends. Given the strategic importance of this type of industry, enhancing productivity through cost-effectiveness, and economic performance optimization has become crucial in such industry. The study proposes an APP optimization model that is both inspiring and realistic, aimed at increasing profitability by minimizing both production and inventory costs. The model is formulated as a deterministic, multi-product, multi-period model, and three alternative optimization techniques were applied: linear programming, genetic algorithms, and hybrid genetic algorithms, as a case study in a steel pipes manufacturing company. The results indicate that linear programming yields the same results as hybrid genetic algorithms, but in less time. Additionally, a feasibility study evaluated the effectiveness of the proposed model against the original planning system in the company, revealing a 12% decrease in overtime wages and a 9% increase in profit. | ||||
